[Q] 5GHz WiFi on Nexus 10? - Nexus 10 Q&A, Help & Troubleshooting

Okay, so we know that dual band WiFi is listed in the Nexus 10's tech specs, and I've had two Play Store tech support people confirm that it should indeed be 5GHz capable, but it just won't recognise or connect to my 5GHz network.
I've had 3 Nexus 10s now (all 32GB), and the behaviour below has been consistently observed on all of them, both in 5GHz only mode and Auto mode:
(The behaviour is identical on JVP15P, JOP40C and JOP40D)
- Does not show my 5GHz network in the network list
- Will not connect if the SSID and key are manually entered
- inSSIDer shows the 5GHz band as empty
I know this is not being caused by an issue with my network as I have half a dozen 5GHz capable devices all working on 5GHz without any problems at all, so my question is; has anyone successfully connected a Nexus 10 to a 5GHz WiFi network?
Thanks.
13 Jan 2013 - Just to update, it appears there could be ranges of channels the N10 will not operate on. These are 52-64 and 100-140. Channels outside theses range appear to work fine.
I would be especially interested to hear from anyone who has got an N10 working on channels 52-64 and / or 100-140.
Thanks.

I have a netgear router my nexus 10 connects to the 5gHz at 300 mbps

I have a BelkinN600 and switching to 5ghz is not an issue for me as well.
Do you have your Wifi frequency band settings on your N10 to run auto or strictly 5ghz? Maybe its checked at 2.4ghz?

Thanks for the replies.
jjdevega - I've tried this setting on both 'Auto' and '5 GHz only' and none of the 3 tablets I have recognise my 5GHz on either setting.
It seems improbable that I've got 3 tablets with exactly the same WiFi fault, so I'm rather stumped as to what's causing this.
Would both of you mind letting me know if inSSIDer shows your 5GHz networks in the spectrum view?
Thanks.

I can verify that 5 ghz works beautifully with the Asus NT-56 router as well.

Make sure the Channel Width (on the router) for the 5Ghz signal is set to 20Mhz, not 40Mhz or Auto.

5GHz worked swimmingly on my Nexus 10. Maybe it's an issue with your router?

It is a configuration problem on your own router if it is not working.

Yup getting the full potential of the 5ghz

Okay, I've been digging deeper into this and I've turned up something interesting.
None of the Nexus 10's I have here seem to work on the 5GHz channels numbered 100+
My network resides on 100 and 104 usually, and all my other 5GHz capable kit can use these channels just fine.
If I set my router to one of the lower channels (I can force the router to 36, 40, 44 and 48) then the the N10's see it fine.
Can I ask what 5GHz channels people are using? Does anyone have an N10 using channels 100+ ?
Thanks.

Mine is using channels 36 and 157. Both are Asus routers. I can see my neighbor's 5Ghz also on channel 157. Time to switch channels I guess.

Thanks, that's really interesting
I'm in the UK so can't use 157 - it's not a licensed channel here and so is disabled on the router Whereabouts are you?
It's curious though - all the channels that require dynamic frequency selection (and transmit power control in Europe) seem to be inoperable on the N10 (channels 52 - 64 and 100 - 140)
36 - 48 are only licensed for low power use, and don't quite provide the range I need. My router chooses 100 and 104 when set to auto and uses them at full power, and this provides the range I need. It's a shame the N10 doesn't seem capable of operating on those channels.

I'm in the States (Houston, TX). Unfortunately I can't use 100 or 104. I just moved my second router to 149, the lowest of the block of channels above 100 available here. I can't think of a way to test your scenario here. Hopefully someone from the UK will chime in.

I can't remember the exact conditions, but I was able to not have my 5GHz network shown on my Nexus 10 one time, and have it shown another. I was messing with channel frequency though, but can't recall numbers used.

Huh. I tried 5 ghz and it doesn't work. Why? Do you need a faster internet to make it work? Ours is 117 MB btw.

Internet speeds shouldn't affect it; it's what wireless channel your router is using for 5GHz that matters. May want to play around with different values.

No worries, thanks for trying. Out of interest, do you know what channels your router would select in automatic channel selection mode?

No, those channels are all licensed for use in the US.
With 5GHz WiFi, a lot of the channels require the use of DFS as part of their usage license. These are 52-64 and 100-140. Because the selection of these channels must be dynamic you cannot force a standards-compliant router to use them, which is why they cannot be manually selected. They can only be selected by the router its self when it is in automatic channel selection mode. In Europe those channels also require the use of transmit power control (TPC).
It appears that the Nexus 10 will not operate on any of these channels, however the reason for this remains unclear.
That means the N10 seems to only operate on 4 of the 19 licensed 5GHz channels in Europe, and only on 9 of the 24 licensed channels in the US.

I haven't ever set mine to automatic. I manually set them to opposite ends of the spectrum, but I could try using auto to see what they do.

Wireless N problem

My Nexus 7 doesn't seem to connect in wireless n. Here's the situation. When my router (Linksys WRT300N) is in mixed mode 2.4GHZ , the Nexus connects fine (using WPA2 security) with a link speed of 54Mbps. If I change the router to Wireless N only (2.4GHZ) , the Nexus can't connect. The Nexus sees the router and I put in the password but it won't connect Now, my HTC Sensation works fine in Wireless N only mode. So is my Nexus only connecting in G?
Anyone else having this issue?

Same here, my Nexus 7 won't connect over 54Mb/s, laptop and Epic 4g touch will just fine. I'm starting to think that either jellybean is broken, or they lied about the wifi capability of the nexus 7.
Mine says 65 mbps so it seems to be on 802.11n (note that this chipset doesn't have 40 mhz channel support so 65 mbps is the maximum). I have a Cisco E4200 router.

I have the exact same router and had connectivity issues. If you're familiar with flashing stuff, goto Dd-wrt and flash the aftermarket firmware (read everything!). Fixed all my problems and UI is much better than Linksys' limitations.
Good luck!

Not so sure its the router
I have this problem too on my Nexus 7.
I've a Netgear DGN3300 which is a/b/g/n 2.4Ghz and 5Ghz. My Samsung Galaxy 2 phone connects at speeds up to 65Mbs fine. My Nexus 7 refuses to connect at anything abover 54Mbs. My laptop connects all the way up to 300Mbs with no problem.
I can have just my phone connected at 65Mbs and nothing else using Wi-Fi and still the Nexus refuses to connect at anything beyond 54Mbs.
While I accept it may be a router problem, with a phone and a laptop connecting fine at N speeds and the Nexus 7 not... it looks like a Nexus 7 issue to me.
If its not really capable of consistently making Wi-Fi N connections then it shouldn't be advertised as such.
Please change encryption type from TKIP to AES from your router settings, and you will have 72 Mbps......
My Wi-Fi is already set to AES which is why my phone works fine at greater than 54mbs speeds.
The N7 simply refuses to connect at anything more than 54mbs.
Maybe I have a faulty N7

All but one of 5 access points I tested at home are set to N only. The WRT54 was not. I have no problem connecting to it and getting good speed while having only a good connection...
At work the access points are set to mixed mode for the very wide selection of devices that need to connect to it though.

Try changing the router channel N uses. I've noticed devices that have "N" not connecting if the channel is above 149.

Edit: Just tried and I didn't see a difference, its worked in the past for other devices like my old Asus netbook. The Nexus 7 has N support right?

FWIW, same problem here. If I put my dd-wrt wrouter into NG mixed mode, my nexus 7 connects fine. If I go to N only, in any frequency, it won't connect. Security is set to WPA2 and AES encryption. It can see the network, but won't attempt to authenticate. I have tried setting a static ip as well. It worked in mixed mode, but not n only.
My other samsung phone connects to the n just fine. There is without a doubt something wrong with the nexus 7.
for those with problems... can you see if the wireless N channel width is set to auto or 20mhz or 40mhz in your settings? If it's set to 40mhz can you try 20 or auto?

Nexus 10 = wifi FAIL

I have been fortunate enough to have enough Nexus 10's in stock at local walmarts to be able to validate a persistent problem with 3 32gb Nexus 10 Devices.
The first one I returned thinking it was simply defective. After the second, I suspected a bigger problem. Picking up a third tonight to do back to back comparisons has confirmed that there is a major problem with these devices and wifi connectivity/stability.
There are two problems that I've encountered on all 3 of these devices. The first is serious catastrophic signal drops at random times with no interference. The second is after network drops due to poor signal, reconnecting results in an endless Authentication/Obtaining IP loop regardless of signal strength that requires disabling wifi and then reenabling before it will be able to connect again.
The signal drops seems to happen consistently at a point in the house where I'm getting around -70 dbm. If I have a good strong signal, the drops don't appear as noticeable.
Network info: e2500 dual band router running 5ghz on channel 40 using WPA2 and 2.4ghz on channel 11 using WPA2. I've changed channels, set to static IP, set DHCP reservations, enabled 2.4ghz only, enabled 5ghz only. Unique SSID's for 2.4 and 5ghz bands. No router settings make a difference.
For good measure I swapped out the e2500 for an ASUS RT-N66U and attempted the same as above as well as playing more with security and channel width, antenna strength, etc. No difference. The issue is software/hardware related with these devices only. All other devices in my home maintain good strong signals. (cell phones, Internet TV's, Laptops, Blu-ray players, etc)
The signal drop was not observed on the newest tablet while it was still running 4.2. It wasn't until taking 4.2.1 that it displayed the same drops. The drops occurred on the devices independently of each other, again indicating it wasn't network related, but a device issue.
The pictures attached were taken at the same time for each device. They speak for themselves.

I havent had one single wifi issue with my Nexus 10. its running the newest 4.2.1 update. Im also using the Asus N66U Router. I have mine setup to detect both the 2.4 and 5ghz frequencies. Maybe ur security settings on the routers isnt playing well with the nexus? NM: just reread ur article. Not sure how i missed the entire paragrah on the security settings u used. Im not sure then. See if anyone else posts anything. Sorry i cant help any further. mine seems to be working awesome. Sorry about ur luck. Maybe wally world got a bad batch of them in then. I dont like buying electronics from there. for some reason, maybe its just me, the items dont seem as good even tho its the same thing. I always wander if vendors send walmart their 2nds. Who knows.
n10 working fine with asus ac66 router here. I use it on the 5ghz band.. I ran a couple of iperf throughput tests and it worked great in the same room as my router and also on the 2nd floor of my house...
This sound more like a problem with your router. No way are 3 in a row going to be defective...
EDIT: sorry if that sounded asshole-ish lol. I really think you are having problems with you router, so you should look into resetting it, and setting up your router again if need be. Try that, and try going to Starbucks or somewhere with free WiFi to test as well. Hope this helps

I would agree that it seems like a problem with your router. Either that or walmart is giving you the same tablet after you return it.
I know you have tried a lot but I would make sure you update the tablet and then do a hard reset of your router. Seems to me like you may have some issues with settings.

Before I updated my n10 to 4.2.1, I didn't have any issue with the wifi, no discconections, no lose of signal. Once I updated, I found out that all those problems came to me.
Even if it is a 4.2.1 problem and not his router, that doesn't mean the Nexus10 itself has a problem, just the current firmware. I'd be interested to see the same wifi monitoring done using a different router, and then with a different ROM (such as CM10.1)
Nexus 10 = No WiFi Problem...

Have the same issue on two N10s on a Linksys e2500...it feels to be software related

Does no one read?
Two routers, same issues with these tablets on both routers. These pictures are of TWO tablets back to back at the same time. 3 different walmart stores and 3 different unique tablets.
I've also been able to reproduce on my phone's hotspot by moving the phone far enough away that the signal degrades to around the -60 to -70 dbm. THAT seems to be the "sweet spot" so to speak. These drops when happening on stronger signals don't seem to be much of an issue unless you're streaming content. For surfing you don't notice the drop as your strength is still more than adequate. However, at these distances the drops result in freezing in browser and disconnects from the network.
Strange issue. I'm getting excellent WiFi results with my Nexus 10. My router is dinosaur... An Actiontec (not even 802.11N!) provided by Verizon with a FIOS bundle about three years ago. It's sitting in the basement at the opposite end of the house and I'm currently on the second floor. Signal seems just fine. No drops at all in a few weeks of heavy daily use. Any chance of some kind of RF interference?

Try only connecting to the 2.4 GHz and see what happens. It sounds from your post that maybe you have your n10 setup with both 2.4 and 5 GHz at the same time which is causing it to constantly pick the best signal and reconnect. For me personally, the 5 GHz range of my e3000 isnt good enough for me to even program my n10 to connect to it. I use 2.4 only.

No there shouldn't be any interference. I went over the possibilities with a Google support rep and the phones in the house operate at 1.9 ghz and one older phone at 5.8ghz, neither of which would interfere.
Additionally if you look at both devices at the same time, they were showing drops independent of each other so one device would be good at the sime time the other device drops...suggesting no interference.

Tried this and switched security to wpa personal and no change.
The is no specific issue with the nexus 10 WiFi. In fact, I've never had a better performing device signal strength/throughput wise. Look on the xda forums for any device, and you will find people with WiFi issues.
Ultimately, 802.11n is a specification and there are many different implementations of this. Some implementations have issues working with others, for a cacophony of different reasons. Seems you're having a bit of back luck at the moment.
First, you need to simplify your setup. Turn off any turbo boost modes, turn on any compatibility modes and reset to default settings. Turn off encryption. If you still have issues, research the advanced wifi settings of your router, and check nothing is set to a bad setting. If you still can't getgood results try a different router.
Done, Done, Done and Done.
The e2500 is a very simple router. No turbo boost modes, switching to the most basic n option, b/g option, specifying channels, turning off security, disabling firewalls, etc. doesn't make a difference.
And for the last time I DID try a different router using default settings and spent 2-3 hours messing with settings to see if I could find a sweet spot with it too.
Let me reiterate NO other devices of mine show signal drops. Laptop upstairs, Internet TV upstairs, Blu-ray downstairs, Two cell phones (Razr MAXX and SIII), etc. NONE, but ALL 3 Nexus 10's do. There is most certainly an inherent issue with all 3 of these Nexus 10s and they all share the same symptoms. It's a software or hardware design issue persistent on each of these. Even if I was able to resolve the issue with a very specific way of setting up my router, that would still be a huge FAIL. Your wireless device should be able to accommodate very basic and common security and configuration settings.
Instead of making a lot of claims that your device doesn't have problems and there isn't an inherent issue, how about some meaningful testing attempting to reproduce the issue as I've done?
Move to a range where you get -60 to -70 dbm, install network signal info and watch your signal strength on 4.2.1 for 10-15 minutes validating you don't have any drops and screen shot that.
Here's a back to back comparison showing the poor signal on the N10, yet great signal on a RAZR Maxx.
@ga9213
Well, if youre sure its not a router problem, you have 2 options:
Revert to stock 4.2 if you love running stock, OR try flashing several custom ROMs to see if the issue can be temporarily corrected until an official update arrives. (Optional 3rd: return your tablet to Wal-Mart for a full refund and cry yourself to sleep...the end)

S4 i9500 5Ghz Wifi: Wont see SSID if channel >48

Folks,
i have Apple Extreme Base Stations (802.11n - one generation before the latest 802.11ac model).
i'm currently running 2.4 and 5ghz networks. the 5Ghz when set as auto uses channel 149 and up.
the 2.4Ghz is on channel 9 - no problems.
iPhone 5 sees the 5Ghz network if its on channel 149 or any channel >48
S4 wont see it- Wifi Analyser configured to scan all channels does not see it as well.
if i reconfigure the AEBS to use channel 36 or below 149 - the S4 sees the 5Ghz SSID.
I have a i9500 Octa Core international phone. my iPhone 5 is a GSM EMEA phone.
Can anyone explain this? how come iPhone 5 can use channels >48 while the S4 does not.
Per apple its better to use the higher channels to get better performance and they also transmit more power signal than the lower channels.
Thanks

Dont count on this 110% but i believe it is an Apple issue.
I had a similar problem with a new 2012 Macbook Air, in which it was unable to connect to network channels above about 15 i think, router was a Non-Apple router.
Not your exact problem but will hopefully narrow down your search somewhat
I really doubt it. All my macbooks and even a Lenovo X200 sees the 5Ghz network if i use 149+ channels.
Only Samsung lame S4 (sic.) cant see the 5ghz network if such channels are used. either its a driver bug, or the 802.11n implementation in this device is botched.

i'm currently running 2.4 and 5ghz networks. the 5Ghz when set as auto uses channel 149 and up.
the 2.4Ghz is on channel 9 - no problems.
iPhone 5 sees the 5Ghz network if its on channel 149 or any channel >48
S4 wont see it- Wifi Analyser configured to scan all channels does not see it as well.
if i reconfigure the AEBS to use channel 36 or below 149 - the S4 sees the 5Ghz SSID.
I have a i9500 Octa Core international phone. my iPhone 5 is a GSM EMEA phone.
Can anyone explain this? how come iPhone 5 can use channels >48 while the S4 does not.
Per apple its better to use the higher channels to get better performance and they also transmit more power signal than the lower channels.
Thanks
tal

1. Does your router have the latest firmware update ?
2. Wireless multimedia extensions enabled or disbaled ?
3. Latest i9500 firmware ?
4. Low power mode disabled on S4 via *#0011#

1. Yes router has the latest apple firmware. all apple devices and other laptops which are not apple work fine. only S4 does not.
2. Wireless Multimedia EXT cannot be selected on apple devices - the router has virtually zero wireless option configuration except for
Country, Channels and which wireless protocols to support. Currently the Apple routers are on Country: USA (i can only select Americas continent related countries (USA, Mexico, Braizl, Argentina, etc) as the router was bought in the US - all have the same channels numbers).
Needless to say iphone 5 (GSM EMEA), ipad 4 (European model, GSM) my lenovo X200 (europe model, Intel 802.11n WLAN) and my Macbook Pro (US Model) see all 5ghz SSID no matter what channel i select.
3. Latest i9500 per my local provider. i did not put any customer firmwares or stock which are not provided by the locals here.
4. Did not enable any power mode savings anywhere. the phone is like 14 days new

I decided thus
router does not applets
put the country in a router taiwan
channel 56
all devices see 5GHz network
MB Air 2013 MB Pro, MacMini 2012, iphone 5, Ipad mini, Ipad 2 and SGS4 I9500
can you help
I have after installing the country and channel it was necessary to restart the router

5GHz WiFi dropping

Anyone else having this issue? My tablet will randomly stop seeing my 5GHz network, other devices aren't having this issue, and it's still seeing 2.4GHz networks.

Try changing the channel manually in your router settings. Some mobile devices are really picky about this...same issue happens to my gf's Galaxy Nexus. I don't own this device yet, but this is some general advice that I'd try first.

Mine is similarly having trouble connecting to 5GHz networks from time to time. It seems that when the tablet set to 'auto' it stops scanning for 5GHz networks. If you manually set it to 5GHz it will immediately find the network. Hopefully there will be a bug-fix.
check your routers 5Ghz settings. Make sure you have it on a 20mhz channel if given the option as 40mhz or hybrid 20/40mhz will usually give you connection errors.

dont set auto, try manually and check router settings, it could be help to fix bug
Haven't connected mine to 5GHz on either of the dual band routers at my house. I always just use 2.4GHz with all of my devices. I'll try them both in little bit to see what my results are though.

The issue I think is that 5GHz is not nearly as effective at maintaining a strong signal through obstructions like 2.4GHz is. I only get a 2 bar signal in a room on the other side of my router while I get a 4-5 bar connection strength with 2.4GHz in the same room.
I was having trouble with 5Ghz too (I was using 802.11a). In order to even get a stable connection, I had to change channels on the router. But as previously noted, it does seem that it has more problems with obstructions. I sometimes lost connection with just one wall between me and the router, but with 2.4Ghz, everything was fine.
I have never had this problem with my GS3 or with any other phone that I've used on 5Ghz.

I think higher frequency in general is harder to penetrate obstructions. Same with my 5Ghz on both my routers. Will have to change the channel to see if it helps my connections. I leave it on 'auto'
Not having any issue connecting to 5ghz band. It does get a little weak when upstairs but has not dropped.
I was seeing 25 MBS down the first time I connected to my 5ghz, and then it dropped it one day and never showed up until I reset my network and now I'm only getting 8, 12 if I'm lucky.

You saying you were getting faster speeds on 5GHz than you do on 2.4GHz? Or were you just mentioning the speeds because it's now slower on the same 5GHz router?

I would normally only get 8-15 on 2.4ghz on my tablet, and I when I went to my 5ghz network, it was set to auto on the channel width And for some reason it knocked off and I couldn't join again. After I reset it, I was only getting 6 mb on the 5ghz. I just changed it back to 20mhz channel width, and it's flying. 64mbps link speed, and 24mbps down, 2.80 up.

I am having the same issue it losts 5ghz when i try to reconnect. Just reported it to Google they are looking into it.
If youre in the US or canada, Check your WiFi settings, many are reporting their tablets being shipped with wifi region set to Europe. Europe uses slightly different settings then the US and Canada.

I have had issues with my N7 dropping signals altogether. I have one router (upstairs) w/ 5ghz and another (downstairs) on 2.4ghz. My N7 doesn't even see the 2.4 and will occasionally drop the 5 and rebooting won't fix it, nor turning on airplane and off.

802.11ac tests on Google Fiber Gigabit

I have Google Fiber Gigabit. Their Wifi router doesn't support 802.11ac so I attached one that does and so far am able to get over 300Mbps consistently and near 400 with GS5 802.11ac. Might be able to tune router for even higher.
More on Google Fiber here...

If you switch to the 5ghz wifi band you can get 1.2gbps

I do connect to the 5Ghz. In the SG5 WiFi connect info, it shows Link Speed as 866Mbps.
I'll try other speedtest sites as well as look into other router settings. The router is an Asus AC68U.
In comparison, my N7 (2013) tablet can do about 100-130Mbps on same router. And hard wired computers can consistently do over 800Mbps on Google Fiber.
Edit: It might be the test sites because they only use a small sample download when it notices a mobile device and doesn't get a chance to sustain a higher speed, not sure.
Question I have always had is how do you know when the device is connected the ac instead of n? Just off the data speeds alone? Does not seem to be any indicator to tell. I have an ac router and can't figure this out. Any suggestions?

Not true.
For starts the phone only has dual antenna design meaning limited to 866Mbps "link rate".
Next, WiFi has about 40-45% overhead so even at a perfect 866Mbps and perfect noise, which won't ever happen the BEST you could hope to see would be around 500Mbps and again that's all under perfect conditions.
You don't want to be too close to the router or you get overdrive, too far signal degrades.
I would say when you got around 370-380 that's probably around the realistic best to expect. If no other 5GHz devices existed, nothing else wireless connected to your router and you was perfect distance you might be able to get more but a phone is never going to see the perfect conditions and I would be shocked to see a phone do too much better. Maybe another 50M at best but that's about the limit for how the phone is engineered and real world conditions.

You may be right, thank you for the detailed explanation Either way the host servers and such that we download our data from are almost always the cap for our actual download speed of files, so we shouldn't really even reach the 300mbps that he's getting when it comes to real world use.

Yup, and that's the other thing.
Servers traditionally had faster connections because they are serving multiple users at once.
A server with a 1Gbps connection, depending on what it's doing, has a low chance of letting you max out your line even.
All it takes is 2 people and now that BW is shared. Even if you have 1Gbps and the other person only 100Mbps you now won't be able to ever max out your line.
Most speed test sites have trouble even testing, the only ones that somewhat can decent are because they are hosted on the providers net probably on 10Ge connections, and again, imagine if 11 Google internet people did speed test at same time, now that 10gig connection can't max all 11 of you out even.
Faster connections are slowly going to hit a wall. At which point only changes in the way the internet works will make the speeds useful, be this by multiple streams via different path's or just more user multitasking.
You take all that into account and now you have the HW side of things. It takes a decent amount of CPU power to process 500Mbps of data. Phones are just now getting to the point where the CPU can handle such burdens because remember, the CPU's are doing many other things at once. It's not like a router that is specifically designed to handle traffic and even a lot of them struggle at 1Gbps. Just cause something has a 1Gbps port doesn't mean it can process at that
Either way though for a cell phone I think it's great.
I personally was glad when 802.11ac devices started going in cell phones that they went for the 866.7Mbps version of AC. I was afraid they would do like they did 802.11N, single antenna which would have limited it to like 466Mbps, which while half of that is good speed wise still, with the dual you actually gain better coverage because the increased signal gained plus now have more bw for weaker signals.

I believe 802.11n at 5Ghz can only do up to 600Mbps. On the GS5, go to the WiFi settings and click on the SSID that your are connected to. Scroll around and you can see the 'link speed'. My link speed shows 866Mbps, so likely using AC.

Yeah, I actually get better performance sometimes when in next room. I have been able to validate I get an 866 link rate.
Here are the advanced options on my router. Any suggestions on what else to tinker with? Someone suggested actually turning off beamforming, which didn't change anything.

Enable wireless scheduler No
Set AP Isolated No
Roaming assistant disabled
Enable IGMP Snooping disabled
Multicast Rate(Mbps) auto

Will try to torrent some Linux ISOs and see what max is when I get a chance. I was able to get about 500Mbps while torrenting on hard wired computer.

Preamble Type - changing to short should get better BW, not by a lot but some.
Beamforming should be fine either way. Most the newer 802.11ac stuff has it properly finally.
Beyond this though you can't get too much more out of a cell phone. Due to it being a cell phone the tx power on it alone is going to be limited. A laptop has the ability to use much more power thus faster rates.
Link rates are almost always useless though, they give you a very rough idea of signal strength/quality but far from a true reading.
I would say you're probably at the limits of the phone CPU and power wise.
Wow ! DL Speed?! That's freakin' awesome!
Great ! You guys are very fortunate to have that kind of internet connection DL Speed.
Here in the Philippines, We only have a maximum internet connection of 10-15 Mbps that is for commercial or business type connection $140 - $170. 3-5 Mbps around $75 - $130 for residential use. It really depends on the ISP(s). It's so unfortunate and saddening to know that the connections they are providing which really cost so expensive are definitely from either Sprint or AT&T which we all know that these two ISP Sprint/AT&T are the best when it comes to Internet Connection and also known for the reliable and cheap plans/offers. Hopefully AT&T and Sprint have their own branch or company here in the Philippines.
