WiFi Problems - Galaxy S I9000 General

[Q] Do you have speed problems with Wifi? (N-band)
I have wifi N router and set to N only. I have two laptop both wifi N capable. When I transfer file usung file sharing betwen two laptop I m getting speed abt 3Mb/s but when i transfer file between laptop and SGS I only get speed of 300 Kb/s. SGS support wifi N standerd then why it so. Well I use ES file explorer to access file in my laptop over Wi- Fi.

It's a mobile device, they have lower throughput and probably only 1 antenna (most 802.11n devices have 3). There are a lot of factors, but basically, all that's important is that it supports the 802.11n protocol. Optimisation may lead to faster speed boosts over time though.
Network traffic might also be set to a low priority to help ensure the phone runs reliably for other tasks, but I have no idea why exactly it's slower exactly.

I get 1.5mbs from my nas and wireless n network

i get 19.5mb downlaoding speed
and 4.3mb uplaoding speed
on my wi-fi
my connection 500/500mb

I m talking abt internet speed. I m asking abt file transfer speed betn my SGS and laptop
Sent from my GT-I9000 using XDA App

87 Mbps according to mine
i'll grab a screen shot when i get back home

87 seems too much I only get 25 while copy file on hard drive it self
Sent from my GT-I9000 using XDA App

that's actually low for me, but is better than nothing
my PC down in the cine room gets around 218+ Mbps

I get about 80Mbps laptop <-> network (802.11n 5Ghz), and about 5Mbps SGS <-> network (802.11n 2.4Ghz). Not horrible, but certainly not wonderful. I wish it had a 5Ghz radio too, so I could turn off my 2.4Ghz stuff :-/

[Q] Do you have problems with Wifi? (N-band)
Since my phone is on it's way to the repaircenter I would like to ask you all this Question.
I have problems with my wifi connection. The strange thing is, is that my router is brandnew! b+g+N!!!
The weird part is that it has only problems with the N-band
SO I hooked up another wireless router only with the b+g band and BAM it works.
But that's just messed up to have 2 wireless routers one for laptops and one just for my mobile phone...
So can u try the same thing and give me your comments about this issue?

there was already a topic about this
however one topic we did not touch base on, on the other topic was about the B+G bands
if you read the documentations you'll noticed that for N to work at full speed, it must only listen to N no B no G
when you use Mix mode, N doesn't work well
to use N, you need 2 bands, B + G only needs 1 band
if you enable all 3 B+G+N you only get 1 band for all, so making the N useless
the trick is to update all your old hardware that still runs G or B to N
then you can use pure N, and gain full speed
the SGS phone can run up to 87 Mbps on N
meanwhile computers can go up to 280+ Mbps

Can't connect to home WPA2 wifi
Hello!
The problem is that I've been trying to connect to my home wifi like 100 times or more, but I'm still unable to get it working... The wifi it's WPA2 and it has a long sentence password...
Any ideas? Thank you!

[Q] manual wifi fix app?
Hey, like many Android users I'm often having problems with Wifi not connecting to APs. While that can be fixed by restarting Android that takes a lot of time and is more than annoying. There are some apps to solve this issue, they "fix" wifi whenever the screen is turned on (e.g. http://www.appbrain.com/app/wifi-fixer/org.wahtod.wififixer http://www.appbrain.com/app/blade-wifi-fix/com.bladewififix).
That however I don't like either as due to the fixing taking place always wifi connection becoming established takes quite a lot of time. So my question: Is there an app that fixes the wifi connection but does so only manually, e.g. by clicking a widget button?

[Q] Can't connect to Wifi?
I select my Wifi network, I enter in the password, it says connecting, authenticating, connected, remembered, then it says disconnecting, searching, authenticating, and it repeats. The H at the top never disappears, no Wifi icon ever appears, what is the issue exactly?
And yes, I am connecting to a Wireless-G signal.

Don't worry I can't connect to your home network either so it's not a problem with your phone

I suggest you delete the password from the router and try and connect .
If you connect setup again with the password .

I had the same problem and i manage to fixit with "WIFI STATIC". It's free on Market. Access your router config and add your Galaxy Mac adress, then fill the parameters in WiFi Static. It Works! Never had problems again! Oh, i think you have to put your's computer(s) mac adress too in the router.

is there really no such app? :-(

Wifi router working for anyone?

I have a vodafone uk hd2 and have been really impressed with it as a product. I have not had any luck with the supplied wifi router software, I go through the minimal setup and press start and as far as the phone is concerned the router is up and running, the problem i have is that neither of my laptops can see the router.
Has anyone had any luck using it? Is it possible that vodafone have disabled it somehow?
Alternatively so i can manually add the router does anyone have the following details that would be setup automatically;
wep in use? is it 128 pass phrase or 40/128 key?
open system authentication or shared key?
im guessing the wep index would be 1?
Thanks
Search .. it was discussed 10 times already.
Thats as maybe but none of the several threads have a real answer as to why some people have it working and others dont. It also seems that the functionality can be effected by soft reset which isnt ideal at all. Also i havent been able to find any of the above original settings that i asked for in the threads hence the post.
Works for me
Hi,
works great for me - just have to make sure that you're not connected to WLAN with the HD2 when trying. Disabling WLAN, then starting WIFI-Router does the trick for me.
Good luck !
I am on vodafone and wifi router works perfectly for me. It worked when I had the stock 1.43 rom and it works with all the cooked roms I have used since.
i did notice it only works with 802.11g not with 802.11b devices like PSP or some other phones..
Is that really the case that it only works with 802.11g devices? Im fairly sure my netbook isnt new enough to have 802.11g and as such probably wont see the router. Has anyone found a way to get the router visible to 802.11b devices?
Wonder if u have enable the N band function . I think Wi fi router will not work properly when it is enable. I did numerous testing with my laptop and iphone . When n band is enable on HD2 , Iphone can surf net thru HD2 but not the laptop . When n band is disable , device can connect no problem ..... So , to get wifi router to work , just have to stick with g band until someone can solve the issue .
Just to add on my previous post , I tried using WMWIFIRouter , also come back to same result ....

The N band doesn't work anyway on the HD2.. better turn it off.. just because there's a parameter in the registry doesn't mean it works..
I have a N router at home and while it looks like it's doing N and it states "auto" instead of 54mbs, it still connects to the narrow band channel on the router..
N Works

N Works. I have a Linksys WRT320N router that can operate on N only, and the phone connects fine (at regular 2,4 ghz, the new 5 ghz doesn't work). Didn't speedtest.
I tried the standard sharing prog and wmwifi router (different versions) and can only, with a lot of effort, get my laptop on the net through the BT of my HD2. I have the N tweak on. Also did the trying in range of the router.
Any chance it's the computer you are trying to connect with? Tried with my work computer, but couldn't because our Dells have computer to computer(adhoc) connections locked out for security. Does the wifi router function show up as adhoc or access point?

ok, now try and get N speed with only one antenna...
Ok Ive got a similar problem with the wifi router and vodafone
everything works hunky dory wifi router turns on, computer connects all is good only when i try and access a website i get a http error 403 forbidden message as if voda have restricted access i have no idea how this would be possible though.
Ive tried many site same result and many browsers chrome, safari, ie, firefox and opera
same thing
the strange part is that tweetdeck and skype work while the browsers don't
HHMMM
anyone else experienced this problem
As I'm on O2 I was quite keen to flash a new ROM to get the wifi router working as they did the dirty on us by ripping it out of the 1.43 they shipped it with...suffice to say that I'm not overly impressed with it after the couple of trials I've made using 1.66 ROM as the speeds its capable of generally fall short of what you get if you simply connect it via usb and use data sharing..bear in mind that I've only tried it twice so far and as such I may refine my opinion with further trials in different locations but as I was hoping to avoid repeatedly connecting leads to the usb socket it's a bit of a blow sooner or later, wear and tear will be an issue to think about.
my findings
had a play with the router, just to see and initially thought it wasn't working.it connected, but wouldn't pass any data.
25 minutes of my best network technician skillz later still no joy... that is until I remembered the laptop has a fixed ip and default dns server address set. as soon as I set them to automatic, bingo, fully working.
did a speed test from the laptop (mobilespeedtest.com) and got just under 900kbit over 3g. winner!
The connection only shows as 802.11b, but that's fast enough for the 3g connection so no worries.
the only down side is that it's adhoc, so the wifes n95 doesn't see it..but then again thats possibly a blessing In disguise!
EDIT as mentioned by the poster below, I had three connections present, (wap.o2.co.uk, mobile.o2.co.uk and paymonthly.o2.co.uk) and the router wouldn't work on them all, though I forget now which it would and which it wouldn't.
I never tried with 1.43 O2 ROM, but after flashing to 1.66 stock rom I just tried this.
For some reason I have 3 internet connection options:
1) Pay monthly contract
2) o2 active
3) mobile web
My standard connection is "mobile web" so I tried this first, and my laptop couldnt see the HD2 as a WIFI router. I then tried the "pay monthly contract" option and it worked straight away.
Now under my Notifications screen under O2 3G UK, I have two connections running, and the download speeds running the same as my home broadband due to the HSPA connectivity available through the phone.
Anyway, I just thought I would share this with anyone it may help.

keep loosing wifi connection at home

Not sure if im the only one but every so often my tab does not connect to my home wifi, it does connect to my vibrant via tether no problem. Now i have had this issue a few other times and the only solution i can come up with is to do a factory reset, once i do that i have to set up the connection then im up and running. Does anyone have the same issue? Any suggestions? Dont want to keep reseting the tab just to get a working connection.

i dont think its anything to do with the router as i am able to connect my Vibrant and my laptop via wifi and no issues, but with my tab sometimes it just sits there trying try to connect
It is probably your router!
My primary router (WRT300N) connects just fine to my laptop, Wii, HD2 (with winmo) Touch pro II with older android port. But refuses to properly connect the Tab, company laptop (IBM), wife's laptop (Packard Bell), Touch pro II with newer Android ports.
It either does not get a IP or with an IP there is no data transfer.
Connected a WAP54g and all connect just fine!
DD-wrt is not supported for this router (V2), so cannot try that.
Is your ssid hidden? i believe froyo was suppose to able to connect to hidden ssids but try disabling that feature. Change it to wep just to check. I am using wpa2; I haven't had any issues.
Bought myself a new router, and now all can connect just fine.
I have the same problem. It just constantly connects and disconnects. Not sure what to do.
Which is the best router ?
Hello,
i own a TP-Link (TL-WR1043ND) Router. My Speed is "only" 65 Mb/s.
Channel 13
11 bgn mixed
Max Tx Rate 300 Mbps
WLAN is lost after xx minutes when the Galaxy Tab goes in standby.
(WLAN Policy: Never)
Which is the best and fastest router for the galaxy tab?
Thx

Hi,
I have the same problem here, connection gone after a few mins, Wifi shows still connected although I can't access the net.
Contacted Samsung in the UK and they have asked me to return my Tab to them for repair!
Just a shot in the dark, but maybe useful. Some programs like Locale scan WiFi periodically for location info. It drove me nuts isolating the problem when the WiFi tether on my Droid would stop working after 5-10 minutes (random time but constant, because of when in Locale's scan cycle I started the tether). For those that are having problems of being able connect, but then the connection showing on, but seeming dead, that may be the issue. Toggling WiFi off and on reestablishes it, or you could just disable the program doing the scan until you head out to move around again.

The Tab doesn't support 5Ghz 802.11n or MIMO (the tab only has a single antenna) so 72Mbps is the best you can hope for over the 2.4Ghz channel, which you _might_ get if you stand right beside the router.
In most cases, 65Mbps is the best you can expect from any router with the Galaxy tab. Virtually no mobile devices seem to support the 5Ghz spectrum that the "fast" 300Mbps 802.11n requires.
Also, you'll get faster speeds if you change your setting from "bgn mixed" to "n only" and see if the tab still connects.
I often have difficulty connection to my WLAN at home, often I need to turn wifi off & on again a couple of times and leave it for a minute before it eventually connects. I don't think the WiFi in Android is particularly robust.

[Q] WiFi problems and questions

My WiFi on the Atrix crashed all my 3 routers (ActionTec/Dlink/Linksys), sometimes after a few minutes, sometimes after several hours.
The routers needed restart after that. Also wired connections were affected.
I tried messing with static IPs and sleep mode, nothing worked!
Now I upgraded my Dlink DIR 655 from 1.11 to 1.33 (supposedly the best).
Things changed
Now my Atrix takes only itself down, the Dlink keeps working for other wireless and wired devices.
The Atrix says its connected and I get the icon with full bars, however no data is transferred. The market and other apps say network error.
I can switch connection over to my other WIfi network and all is good again.
Has anyone seen this behaviour?
Also is there an app that shows me the link mode G or N and the current link speed? I cant seem to find a good app. I would also like to see if I can lock the Atrix to G or N only. Is there such a toggle switch?
Thanks.
Update: Switched connection from Dlink to Linksys and it worked for about 30 minutes then the linkksys crashed (could not reconnect got no IP). Switched back to the Dlink, got connected, good signal but no data. Even after a phone reboot. So I think it might be still on the DLink side although I have Netflix (PS3 wireless) and another PC connecting fine. This and the VOIP mic problems (Skype etc...) bug me the most about the phone.
ive been having this same problem since i got my phone and im still having problems. its pissing me off. cant even use my netflix through the Wii to watch on the big screen

Nexus 4 ruins my home wi-fi !?

Every time i connect nexus 4 to my home wi-fi. Every other device gets terrible connection speed... Before nexus 4 my Nexus 7 had steady speeds up to 20mbps. With nexus 4 connected speeds go down to 5-3 mbps and even when i disconnect n4 from my home wi-fi router still acts really strange and i have to reboot it. Anybody experienced anything like that?

I have three desktop computers, an iPad, an iPod, a Roku unit, and two smartphones sharing the same wifi signal. My speeds don't seem to vary any regardless of the number of devices sharing it at any given time. I would have to call my service provider if I found myself in your situation.

Yep, same.
To the op, I'd say either reboot the router (which you probably have done) and / or see if there's a firmware update for the router.
If no cure, call your internet provider.
Ok.. Forgot to mentioned that n4 also loses wifi connection from time to time.
Seems like im not the only one.. People post similar problems.

I have seen this before. It happens in mixed networks (old B laptop used to crash the WiFi AP when G clients were also connected).
1) Check for a firmware update to your router. This is most likely where your issue is. The router speed should drop and increase as needed, but buggy firmware may only keep in last slowest speed until a reboot.
2) Mixed encryption (WPA & WPA2) is a nightmare Force "WPA2 only with AES only" -or- "WPA only with TKIP only". Some clients may try to use WPA with AES and this was what was crashing my AP at the time.
3) If you still have issues, try using "G&N" only, or even force G only. Some older G clients don't hear N traffic, so they just transmit on top of it.
4) Last resort, look for a used router that can run DD-WRT firmware. Personally, I will never go back to OEM router firmware.
Hope this helps...
i used Wi-Fi Analyzer and it showed 2 really strong signals on the same channel.. one being mine and the other someone's else. i manually changed it from 11 to channel 5 and everything back to normal/// 20mbps just like before!

Hi every one. I just got my N4 last week and i experiense the exact same thing!!!!
this is realy bad because every time i use the wireless network every body in the house starts complaining because my N4 shuts down all connections here.
It works alright with the main router wich is a thomson. but it fails with the other two routers (that are Belkin - N) that are only access points!
I realy want this fixed because not having internet at home is quite bad!

[Q] G2 WiFi speeds N+AC

Does anyone notice there's a big bug with WiFi on the G2?
I have 2 WiFi ac routers, one at home and one at the Office, an Asus RT-ac66U and a Linksys ea6700. Both capable of 1750mbps max speeds.
Internet speeds are 120/6 and 200/20.
Scenario is exactly the same for both routers;
When fresh reboot the router, G2 connects at a speed of 433Mbps.
Speedtests show results of 119/6 at home and 190/20 at the office.
Great you would say!
But here goes. Once WiFi get disconnected and reconnected, speeds go down to ~40mbps. No matter what I do!
These are N speeds, not AC
When looking at connection settings it still shows a link of 433mbps
Tested dozens of times, on both routers, so it has to be an issue with the G2.
Anyone else noticed the same??
DAMN, should have been in Q&A, mods plz move
I'm not an expert on wi-fi, but have stumbled through setting up several routers around the house. But I do not have an ac router.
Is the home router in mixed mode? Ignoring a/b/c for a moment and focusing on g and n (and implying ac), I have two wireless routers in the house. One runs N only (but both 2.4 ghz and 5 ghz) and the other runs G only. Now, my N router is capable of running in mixed mode (to handle both N and G) BUT in mixed mode, my max speed when connected in N is lower than it would be if I ran in dedicated N mode.
Most of my devices now are at least N (2.4 or 5) but I have an older printer and wii that only do G. But as mentioned above, rather than run my best router in mixed mode, I run 2 separate routers, one in N only and one in G only.
Maybe something similar might help with your ac speeds?
Really appreciate your input!
But I already tried settings like AC only etc. Doesn't make any difference.
Once connected for the second time and up to the router no more AC speeds...

Is there a way to test LAN speeds on Android? I have the same Asus router but my wan speeds are so pitiful that I wouldn't be able to tell if the phone was dropping to N speeds. If I could test speeds to my desktop across the local network I might be able to test what you are experiencing.

Is there a way to check on the phone, which band it's connecting to? I haven't found anything.
I have the same router and my issue is on reconnect. I leave my wifi on all the time. When I get home, it connects automatically the moment I pull up to the house. The problem is, the speed is severely crippled. Range is awesome, speed is bad. I have to cycle the wifi and reconnect. Once done, no more problems.
One thing I should note, I was having the same issue occasionally on my Droid RAZR after getting the ASUS. Does anyone know if they use the same wifi hardware? Maybe it's an issue with the router itself?

@jasonff
Don't know about an app to test lan speeds unfortunately.
Think a google search would come up with lots of options.
@crashN2u
I leave my wifi on too all the time for now, it keeps it at full speed then.
There's no way to check which band you are connected to.
Router doesn't have an option to choose AC Only, only N +AC
And in the mean time I have tested it with 4 AC routers, Asus RT-AC66U, Netgear R6250, Linksys EA6700, D-Link 868L.
With all routers exactly the same conclusion. First time everything is great. Excellent speeds. If you never turn off WiFi it remains at high speed.
But once you turn off WiFi on the Phone and turn it back on it immediately drops to ~36-40mbps max (N Speeds).
This remains until I rebooted each router and after that full speeds again.
It must be something in drivers LG used.
There's the solution to for, I'm sure of it by now.
Well, I can see I won't be much help -- especially since the same result on 4 routers!
I am not sure if the following app supports AC, but a very helpful and free app I use is called "Wifi Analyzer". I can't post links but that is the exact name (author = farproc).
It has many useful tools/functions that you may find helpful, switchable between 2.4 and 5.0 ghz, channel scanner, etc.
Does your 2.4 ghz N and 5.0 ghz N/AC have different SSID's? From what I read, AC is 5 ghz only and N can be either 2.4 ghz or 5.0 ghz. I wonder if you are dropping from 5.0 AC to 2.4 N because the 2.4 N is being detected as "stronger signal" than the 5.0 AC at reconnect time?
I named my 2.4 ghz N SSID as "Blah" and 5.0 ghz N SSID as "Blah_5ghz" just so I know what frequency I'm on at a glance (using a widget that shows the SSID) but many routers by default will have both SSID's the same, making it less obvious what band you are connected to. I also use an app called "WIFI Prioritizer" (author Robert Botha), which will allow me to connect or re-connect in the SSID order I specify: i.e. when I get home I will connect to SSID "Blah" (2.4 ghz N because it has the longest range). Every 5 mins (you can specify), it checks to see if my SSID "Blah_5Ghz" is in range and will switch to it if it is (you can also set signal strength connect and disconnect thresholds).
Anyways, I probably can't help further but am following this thread with interest. Good luck!

Well, I can see I won't be much help -- especially since the same result on 4 routers!
I am not sure if the following app supports AC, but a very helpful and free app I use is called "Wifi Analyzer". I can't post links but that is the exact name (author = farproc).
It has many useful tools/functions that you may find helpful, switchable between 2.4 and 5.0 ghz, channel scanner, etc.
Does your 2.4 ghz N and 5.0 ghz N/AC have different SSID's? From what I read, AC is 5 ghz only and N can be either 2.4 ghz or 5.0 ghz. I wonder if you are dropping from 5.0 AC to 2.4 N because the 2.4 N is being detected as "stronger signal" than the 5.0 AC at reconnect time?
I named my 2.4 ghz N SSID as "Blah" and 5.0 ghz N SSID as "Blah_5ghz" just so I know what frequency I'm on at a glance (using a widget that shows the SSID) but many routers by default will have both SSID's the same, making it less obvious what band you are connected to. I also use an app called "WIFI Prioritizer" (author Robert Botha), which will allow me to connect or re-connect in the SSID order I specify: i.e. when I get home I will connect to SSID "Blah" (2.4 ghz N because it has the longest range). Every 5 mins (you can specify), it checks to see if my SSID "Blah_5Ghz" is in range and will switch to it if it is (you can also set signal strength connect and disconnect thresholds).

My Phone is packed with tools like Wifi Analyser, InSISDer etc etc atm
I always separate 2.4 and 5ghz networks to be able to see exactly what's going on but thanks for the heads up :good:
From further investigation and thinking, and with your suggestion about stronger signals;
Thing is, AC routers are more or less all simultanious routers.
That combines 2.4 and 5ghz signals for higher transfer speeds.
I think in there lies the problem when drivers are not 100%.
In theory 2.4 signals are stronger then 5ghz signals and have wider range.
But in testing I made sure that I was in the same room and no more than 2 meters away from the router.
when testing it showed equal signal strength up to -20 so really strong signals.
Therefore I concluded that N on 2.4 whas equally strong as 5ghz and then again I isolated 5ghz SSID so that's not it unfortunately.
I promised to stay away but I can't resist!
Have you tried some of the more generic troubleshooting tips (on the home network), such as trying with no security or lesser security (WEP) to see if it still reconnects at the lower (N) speeds? I realize that usually that test is of course for a more basic issue than yours but maybe the G2 has trouble handling security overhead.
Some devices and routers just don't like each other (as many know), but 4 different routers...?! Gotta be the G2 side, as you've surmised. Wish I knew someone with an ac router so I could test myself. I'm debating on getting an ac router but you've got me spooked! (kidding/teasing)
Well haven't tried lower or no security.
When I have the chance (aka the wife is away and not *****ing about wifi not available ) I'll sure try that.
But I don't think that WEP will be an option because AC requires AES protection if I'm not mistaken.
But really do not be afraid to get yourself an AC router hehe.
No honestly, I've tested 4 routers with:
AC Capable:
HTC One. Goes all the way to max isp speeds. All the time, no issues
LG G2.
Not AC Capable.
IPhone 5. Max speed at 5ghz (constantly tested) is ~90-100mpbs.
HTC One X. Max speed at 5ghz (constantly tested) is ~70-90mpbs.
So even if your hardware maybe not be capable of AC speeds you still get excellent connections
Oh and for the record.
Here's my personal listing of the hardware I've tested. From best to well not so good.
1. Netgear R6250.
Excellent constant speeds. No drops whatsoever with around 6 devices connected. Excellent range!
2. Asus RT-AC66U
Shame Asus introduced a new wifi driver some time ago which doesn't perform that well. Constant speed drops.
They know about it but thusfar no solution.
When you get this one, stay on old firmware for now!
3. D-link 868L
Real looker this one. Can be put in plain sight in the room like a picture frame :silly:
Great constant speeds, but some drops here and there.
Excellent range.
4. Linksys EA6700
Linksys is sold to Belkin by Cisco.
Up to now I have never seen anything good coming from Belkin!
What a piece of crap.
With a really thin wall between router and phones coverage went down more dan half. Hell even when distance less than 2 meters away coverage was about -45.
Do not get this crap!
I wonder... the wireless N spec (not sure if also AC) calls for devices and routers to have a 'low power mode', which may or may not be enabled in routers and/or phones (e.g. GS3) by default. According to some article I read, newer routers may go into a power saving mode if it detects low traffic and supposedly ramp up when the traffic increases.
Possibly it doesn't ramp up fast enough when a new device connects and the device mistakes it for not having the highest speed (AC) capability. Might explain fast speeds after router bootup but not later. If there is any truth to that (no clue here), it might speed itself up either by testing with a larger file or seeing if the "2nd connect" condition changes while say, streaming videos from the PC to the Xbox or watching Netflix on the main TV. Certainly, either would be considered high traffic and if there is no change to the 2nd connect, well -- there goes that idea.
Is there a wifi power saving mode on the G2 like there is on the GS3? (i.e. dialing *#0011# to turn it off).

Good point!
Well, there is a setting in wifi, advanced to minimize use of wifi when screen is off. Sounds like a power save mode to me.
But, just tested it and that makes no difference.
With that setting deactivated on the G2 still at first boot AC speeds and when I switch off and on wifi I still get N speeds max.
And besides that, on the Asus router there's a setting called "Enable WMM APSD". Which stands for "Automatic Power Save Delivery".
I read up on that and the custom firmware guru RMerlin writes about that setting that especially Android devices could suffer from that setting.
So I disabled that a long time ago.
On other routers I couldn't find such setting.
But to iron that setting out I just tested it once more.
First with setting off. Still first connect AC speeds, after turn off/on back to N speed.
Then turned wifi off, enabled the setting and rebooted the router.
But this time to let the supposedly power save kick in I let my Phone idle for 15 minutes so that it surely was in deep sleep.
Then turned screen on, and again AC speeds when first connected.
After that turned wifi off, screen of for 15 minutes. Turned screen on again and once more N speed.
And link speed is always shown as 433mbps btw, which is correct.
There's just some bug in driver code by LG which doesn't work correctly.
I'm more and more convinced of that.
For now I just keep wifi on all the time so that I always get full speeds.
Batt is capable enough so no problem there

I found a tool to test local network speed. It uses two android devices for a p2p test or you can install a server program on your PC. I'll do some testing and see if I can reproduce what you are seeing. Here's the link: http://pzoleeblogen.wordpress.com/2013/08/12/local-network-speed-test-for-android/ and the market link: https://play.google.com/store/apps/details?id=com.pzolee.android.localwifispeedtester&hl=en
And to be sure I understand, you boot your phone with wifi on, AC speeds. Turn off wifi on phone and turn it back on, N speeds. Reboot phone with wifi on, back to AC speeds. Correct?

Thanks for the app!
Gonna test this for sure since I also have a HTC One lying around which is also AC capable
Not 100% corect.
I can do with phone what I want until wifi gets turned off.
Then a reboot of the router is required to get AC speed back.
No need to reboot the phone.
Quite busy atm so don't have enough time I would like to be testing

Between my wife on her laptop, my son on his Chromebook and my daughter streaming Netflix on our Roku, I hardly ever have a chance to reboot the router without someone complaining
Since I haven't rebooted my router in days, from what you are saying I shouldn't see anything above N speeds until I reboot the router. Do you actually have to turn off wifi on the phone to have it drop from AC to N or is it enough to leave the range of the wifi and then come back? And does if turning it off is required, do I have to be connected to the router at the time I turn phone wifi off?
I'll try testing this weekend.

Going out of range isn't a problem as long as you don't have an app or setting on in wifi, advanced to switch off wifi.
As long as wifi isn't turned off I can go everywhere, in&out of range, other routers connect but speeds remain AC, everywhere on every router.
I can reproduce everytime that when I turn off wifi on the phone and back on from then on I only get ~36-40mbps max.
It's like the phone thinks that's max capable speed altough wifi link speed is again shown as 433mbps.
If I have switched off wifi on the phone and back on, on all 4 AC routers I tested all needed a router reboot to gain full AC speeds again.
Oh and maybe a small tip, I always say to the misses at home that there's a small problem with connection so a quick reboot is required.
Up to now that still works

I just did a few tests from my phone to my pc with 100MB data sets. I got between 200 and 260 Mbit/s down both before and after toggling my phone's wifi off and on. Didn't seem to make a difference. I got about 6Mbit up.
So, I didn't seem to experience the problem you have. But try repeating what I've done with this local network app. Maybe you won't have the issue with it that you are seeing on your WAN connection.

Wow and do you really see real transfer rates of 25-30 MB/s to your G2?
I'm using a Qualcomm Atheros based AC-router and my G2 (running latest CM11) hardly goes over 10 Mbit ~ 1,5 MB/s. Weak I know. (Confirmed 433 Mbit link using a wifi app.)
Maybe I need a broadcom-router like yours to see some real AC-speeds.
Thanks for the reply. Take care
