Slow WIFI connection...

How come I get so slow speeds when copying a file over WIFI from my desktop computer? I get about 420kb/s and when I check the WIFI connection the signal quality is 70% or higher and connected at Tx 54Mbps / Rx 48Mbps.. Shouldn't I get something like a few Mb/s with that connection??
Using Resco Explorer to access shared folder on desktop computer and copy files btw...

Is it set for best battery? If it is, that's the problem.

No.. Best performance...
Any idea why its only giving me 450ish Kb/s? What SHOULD I be getting with 54Mbps?
The WIFI router is a Zyxel P-320W btw.. It supports 802.11b/g..

if you read specification of your phone you should know this, taken from htc homepage
Up to 7.2 Mbps download speed
Up to 2 Mbps upload speed
so i dont think it matters if you got 54/48Mbps
this is my guess to your issue
someone right me if im wrong here..

Damn.. Thats slow.. Can't even watch XViD's over WIFI..

you might want to enable wireless N through either BSB Tweaks or
Tboy2000's thread...it might help?

7.2 Mbps = HSDPA, 2 Mbps = HSUPA
NOT WiFi

So what is the supported WIFI speeds on the HD2? 802.11b/g is supposed to be alot faster than the ~5 mbits I seem to be getting Or is the network(WIFI/HSDPA etc) controller limited to 7.2mbps be it WIFI or through 3G?

Well, those 7.2mbps and 2.0mbps are probably not wireless specifications as they stand for HSDPA connection. Wireless speeds are specified by 802.11 standards, e.g. 802.11a supports up to 2mbps bandwidth, 802.11b up top 11mbps and 802.11g 54mbps. so, these should be the speedlimits for HD2. I have seen that it is possible to enable 802.11n for HD2 but i havent tryed it out yet as I have difficulties using wireless with my HD2 even with the slow speeds.
no matter where I try to use wifi, it works for ~30secs and after that the phone can't find any wireless networks, sometimes even hangs. After waiting for about 1 minute, it finds wifi again and same scenario happens again and again. It hasn't worked right from the moment I took it out of the box. should return it probably but before that, maybe someone has had same problem and knows what the reason is for that?

Best wi-fi performance

I noticed in the advanced wifi settings the option to tick 'best wi-fi performance' it says this may use more power. Anybody know what it actually does? Also is the DHD wireless n standard without having to do anything?

What rom are you using? I do not see this on leedroid

Just the standard ROM that comes on the phone as i havent rooted.

I have a question on this also

It will be there. You have to press menu on the wifi settings page.

Yep, this definitely uses more battery, this unfortunately is a must for me since I have the phone in a case and I get very poor reception with Wifi otherwise. GPS is also weak takes ages to lock.
It's under Settings -> Wireless & Networks -> Wi-Fi Settings -> Press menu button -> Advanced and it's there.

So enabling it will help WiFi reception? I though it will only boost speed or something. Going to turn it on for a few days and see!

Remember that the signal is never 100% and there is some loss in speed. I always use best wifi performance as it improves the signal and from my room which isn't too far from the router I can max my 5mbs connection which I find quite impressive. On 1.5mbps connection you should be maxing at around 170kbs.

it need more power than normal using

but, i dont know in leedroid hay rev have it

Speedtest.net with best wifi performance: 3703 kbps down 1244 kbps up
Without best wifi performance: 2909 kbps down 1214 kbps up
Makes a slight very slight difference. This was upstairs away from the router. Downstairs I can get 9-10 Mbps whether it is on or off, whereas on my laptop I can get 12-13 Mbps.

It does not apply the n-setting, because if I turn on the n-setting on my router, my phone disconnects from WiFi.

I suppose you have a 1.5 megabit connection and a downstream of 600 kilobyte per second? One byte = 8 bit.
Because if it is like that, you should, as ErOR22 mentioned, not be able to get over 187.5 kB/s (if my calculation is accurate ^^).
If you really mean that you have 1.5 megabyte downstream you could try to get closer to the router and/or minimize the number of walls between you and your router. This should boost your speed.

battery drains real bad when you switch best performance to on and it does activite the n setting its one off HTC's power saving tricks. I have dual band router an my DHD connects fine
for signal, covering the battery cover kills wifi as thats were the antenna is.

My line is 1.5mbytes not bits. I usually hit 1600kbytes a second on my upstairs computer using WiFi g and not n. I should easily be getting 1MB/s at least on my phone
Edit: just did a few speed tests, 1mBps but when doing a lan transfer, it peaks at 900kBps averaging 600kBps. This is my problem. Lan share is useless

That's interesting, you got your numbers wrong again lol. On 1.5Mbs connection you say you download at 1600kbs which is 1.6Mbs lol. Funny that, on LAN you should be getting a lot more. When testing LAN are you coping from from another computer that's on wireless?
When I turn on Best WiFi Performance I idle at around 70mA and with it turned off it's under 10mA, so a huge difference but I need it unfortunately.

lowercase b is bits
uppercase is bytes
8 bits per byte, 1024 bytes per kilobyte, etc etc
speed varies because because tv runs off the same line. ~15mb/s without any TVs going or shows being recorded and ~10mb/s or so when 2 or more are being used, but I still only get like ~6-7mb/s on the dhd, same with lan shares accessed from the device

You have your units all mixed up.

Slow WIFI Transfer

Hi,
I would like to ask if it's normal to have <1MBps wifi transfer rate on my Galaxy S4. I'm trying to transfer a movie file from my phone to my PC (gigabit-lan) via my TP-LINK N750 router.
I checked my phone and it's currently connected using 2.4Ghz spec with 72Mbps linkspeed. Theoretically.. the wifi transfer speed should be around 8MBps not <1MBps.
Any clues why my transfer speed is slow? My forte is more on network stuffs so I'm not really sure if my phone is causing the bottleneck here or not. See attached for reference.
Thanks guys!

I have the same issue across several different ROMs and modems. Laptop with external HD is connected to router with gigabit LAN, phone connected to router via wireless-N and I get roughly 1mbyte/s. However download speeds with my phone via WiFi is roughly 8 megabyte/s (fiber optic) so I know higher speeds are possible.
My other desktop PC achieves around 11-12megabytes through WiFi but my phone just gets nowhere near it.
Odd thing is when I stream videos to my phone though my WiFi from a hard drive the phone buffers at well over 5megabytes/s but file transfers are somehow limited... I could never figure this one out

Thanks Swizzy!
I also noticed this.. somehow I thought it was because of my router. So I decided to buy 450Mbps Dual Band router to test it. Unfortunately, it is still capped @ ~1MBps transfer rate even I used the 5Ghz spectrum

Complain to google
I have done some testing with a fast windows 7 system as the target and a Nexus 5 and an xperia neo v. I have also tested with XP and Linux smb clients. Basically the maximum I get get with stock 4.4.2 or 4.0.4 is about 4.5 Mbps (550KBps) pull down and 9Mbps push up. Wifi is 11g and XP gets 15 down and 19 up. openSUSE linux gets more or less the same as XP. The problem exists with ES Explorer and File Manager. I tried SFTP into linux with ES Explorer and that was a little slower. The standard USB transfer from windows explorer is really fast to the N5. This looks like a design or configuration problem in android 4. Complain to GOOGLE.
I am glad I found this just before I spent a lot of money on an ac router to speed up large wifi file transfers

So a device running pre version 4 should not have the limitation?

I have a Galaxy S4 with the newest firmware from samsung I9505XXUGNF1 (Kitkat 4.4.2). My router is a Asus RT-AC66U to which My S4 connects to with max speed of 433 Mbps. My internet connection is 120 Mbps.
When I do a speedtest on the S4 I get results of over 110 Mbps, but when I'm downloading a file over LAN from the disk connected directly to the router I get download speed only of ~20Mbps (2.4 MB/s) which is very sucky!
My Laptop have only a N network card, and connects to the router with max 300 Mbps and when I download the same file I get over 7.5 MB/s!! (~65 Mbps).
Speedtest also shows results of over 110 Mbps...
I remember when the phone was new, and it had Android 4.3, I had LAN download speed of over 9-10 MB/s...
I tried with different file managers like X-Plore and others, but it looks like it is not the app problem. Maby is a KitKat problem??

In short blame Broadcom or Samsung for using Broadcom BCM4335's BCM4335 wifi chipset. You need to understand how 802.11n works. To achieve 300mbps speed, you will need 2-3 spatial antennas which can be found on modern laptops with Intel Wifi chipset (such as 6300). Our galaxy note has only one antenna (should be 1 for each radio band (a/n, b/g/n), but it is "N" compatible. Unfortunately this is a case of the manufacturer misleading it's customers ( I would say out right lying to us). Its is compatible with N, however it can not support N speeds, as far as I have seen all phones that claim 802.11n are actually limited to 65mbps. So really are not 802.11n at all, rather just a little faster than 802.11g.
part of the problem is the maximum number of data spatial streams the radio can use. Also assuming equal operating parameters to an 802.11g network achieving 54 megabits per second (on a single 20 MHz channel with one antenna), an 802.11n network can achieve 72 megabits per second (on a single 20 MHz channel with one antenna and 400 ns guard interval); 802.11n's speed may go up to 150 megabits per second if there aren't other Bluetooth, microwave or WiFi emissions in the neighborhood by using two 20 MHz channels in 40 MHz mode. If more antennas are used, then 802.11n can go up to 288 megabits per second in 20 MHz mode with four antennas, or 600 megabits per second in 40 MHz mode with four antennas and 400 ns guard interval. Because the 2.4 GHz band is seriously congested in most urban areas, 802.11n networks usually have more success in increasing data rate by utilizing more antennas in 20 MHz mode rather than by operating in the 40 MHz mode, as the 40 MHz mode requires a relatively free radio spectrum which is only available in rural areas away from cities. Thus, network engineers installing an 802.11n network should strive to select routers and wireless clients with the most antennas possible (one, two, three or four as specified by the 802.11n standard) and try to make sure that the network's bandwidth will be satisfactory even on the 20 MHz mode.
Data rates up to 600 Mbit/s are achieved only with the maximum of four spatial streams using one 40 MHz-wide channel. Various modulation schemes and coding rates are defined by the standard and are represented by a Modulation and Coding Scheme (MCS) index value. The table below shows the relationships between the variables that allow for the maximum data rate. GI (Guard Interval) : Timing between symbols.[6]

I see similar speeds on my S4 when doing wifi transwer. varies depending on which network i am on and what I am transferring to.
still faster than crappy USB connection..

@XeoNoX thank you for educational lesson.

WiFi Powersave mode
You may check if the WiFi power save mode is on. If it is on, you may turn it off and check if the speed improves.
To enter Service Menu, open dialer and press *#0011#
In the service menu, select menu > wifi
check if the WiFi power save mode is on or off. Turn it off.
If it was off, then you've wasted your time trying this

[Q] LG G2 WiFi speed

Can someone explain why my LG G2 connects at 39 mbps to wifi router N(150 mbps) ?
I have 2 other phones and tablet and they all connect to 150 mbps link speed and internet speed is realy blazing fast.
On my G2 I got around 2 MB/s MAX, usualy ~ 1 MB/s (I thought that G2 supports all kind of wifi standarts - a, b, g, n, AC ?)
P.S. router has latest firmware! No other devices has this problem.

Are you connected over 2.4 or 5 GHz? That can make a huge difference. Use 5 GHz band if possible.

In the wifi settings choose 5gz only and see if it will connect.

No difference at all, I've tried to use 11N only and bgn-mixed - still no difference. G2 connects to router using link 40-50 mbit and the best download speed achived is ~2 MB/s other devices ~10 MB/s
...I have another N router - same problem there..
any other suggestions ?

You realize that its 150Mbps INTERNAL. Not external. Meaning. You get 150Mbps wifi transfer between internal devices..

1) Yes I realize that. BUT the thing is that I have INTERNET download speed of ~15 MB/s AND other devices download with ~12 Mb/s
I've tested to download file from my local PC to LG phone using wireless storage and I barely get over 2 MB/s. I'm definitely using WiFi as I turned off data network.
Also, other phone tablet and PC shows Link connection speed 150 Mbps, only G2 is connecting to the routers on 39 Mbps or even lower.

This shoud not be a problem as connection to the router does not play role in WiFi connection speed, plus 100 mbps is like 12.5 MB/s which is much more than 2.5 MB/s; Plus I've got cat 6a patch cable that interconnects my router to modem and PCs so I've got 40 MB/s PC to PC speed and Tablet to PC ~ 10MB/s (same router); my tablet conection speed is 150 mbps
Only my G2 connects to router using 72 mbps speed link (I've tried all variations of settings - no luck)

I can connect to the 5 GHz network but i can't get expected 433 Mbps link speed with a AC Router instead of that it only gets 72 Mbps (WiFi N).

Maybe try a custom ROMto see if it is a hardware issue or a ROM issue? I have no issues with 433mbps on 5GHz AC.
If you can also try another 5GHz network to ensure that it isn't a compatibility issue with your router, then we can narrow down the possible issues.
Did it ever connect at a higher rate than 72mbps? Or have you only had this phone for a short time? Maybe see if you can find an older stock ROM to fastboot flash to ensure it isn't the ROM that is messed up?

In 2.4 GHz it's completely normal unless you set your router channel bandwidth to 40 MHz (not recommended if you live in a very populated area with a lot of nearly WiFi networks) and enable channel bonding on your devices and you'll get 150 Mbps.

I unlocked the bootloader and flashed latest fastboot ROM with MiFlash using clean all and lock, I'm still getting 72 mbps but the WiFi signal has improved and also now I have Mi Drop, Mi Community and Mi File Manager preinstalled. I'll try a custom ROM in this days and I'll post the results.

In which channel if your 5 GHz network working?
PD: This is my second Mi A1 because the previous one got stolen from my house so when I bought it the first thing that I did was installing Oreo and then a factory reset. Also I bought the new router the next day so I've never tested it with Nougat.

It's on auto, currently channel 36. I have no problem with 433Mbps connection on 5GHz, being about 20 feet away in another room with 2 walls in between. I can be upstairs in a bedroom, not directly above the router, and still have over 300Mbps connection.
This is running a Linksys EA6900 router with XWRT Vortex/Merlin custom firmware, and Mi A1 running Pixel Experience with Franco Kernel R2.

I'll give Pixel Experience a try if Xiaomi doesn't launch Android 8.1 with Project Treble this month.
