The I747MVLALH1 OTA Telus update has disabled the ability to change the Wifi frequency band in Wifi Settings Advanced. I had mine selected at 5GHz. Now I can't see 2.4 GHz SSID's. I had selected 5GHz because it solved a problem with Wifi disconnects.
Any ideas on how to fix this?

OK I'll answer my own question! It seems that others have had this issue as well with other carriers and other than applying this fix:
http://forum.xda-developers.com/showthread.php?t=1801993
(which I'm not even sure will work on Telus) you can do a factory reset. I did, and it sorted the problem out.
Oh well ...
IDK.
I put this on today, and is it me or can anyone else verify that the WIFI is WORSE than the prior official release?
I run 2.4 AND 5Ghz wifi in my home. Both are "N" Only, and I even have an extender for the worse part of my home for 5Ghz. Here's a photo of my connection and guess which one the GS3 is picking to connect to? The 2.4 network....
I DON'T like that I can't select the band (2.4/5Ghz) anymore.
I DON'T like that it seems to have ZERO logic to pick the strongest signals.
It DOESN'T appear to like to pick the 5Ghz band anymore. Even when you force it to.
Does the leaked LH1 work better?
(I uploaded a second shot after I reconfigured my extender to drop the _EXT, and that worked a bit better, at least it's 150mb again; I have 60mb service.)
There is a flashable cwm zip that is for wifi band selection the are 3 settings auto/2.4/5.0

I was wondering if there is a way to make my tMob SGS3 do better at seeking and maintaining a WCDMA connection?
I know I can change the Mobile Network Mode to WCDMA only, and I do sometimes.
However, when it is in Auto mode, it switches back and forth constantly between GSM and WCDMA. In my home when I force WCDMA mode it has 2-3 bars of WCDMA and it does not drop the connection. When I put it on auto, it switches back and forth every minute or 2. I flashed and tried every modem possible but the results are the same.
Is there any way, besides WCDMA only mode, that I can make my phone more aggressively seek and keep WCDMA when it is available?
Thanks!

Dude I feel ya. I seriously think it all started once they switched to the 1900 band for 3g. Cause when I had my HTC HD2 it was mostly 3g in my house. Now it hardly ever switches to 3g unless I force it.

It works great when I switch it to WCDMA only, however I keep forgetting to switch it to GSM/WCDMA when I leave the house or work. I'm thinking of getting some TecTile NFC stickers to cause my phone to remind me to switch or maybe try to find a way to automate it with them or something.
If it sits at G or E until you start a data transfer and then jumps to 4G this is how it was originally set up to operate. The intent was to save both battery and banwidth. It was like this for me until I updated and it stopped. It was annoying so I'm glad it was changed. But if you are on either build UVALEM or UVALG1 try updating to the latest official build UVALH2.
Otherwise it may just be the tower you're connected to is under heavy load and is trying to conserve bandwidth, or it may just not be functioning correctly.
One other thing it could also be is if your area hasn't been refarmed yet. (It may be that this is what changed it for me but its been a while and I know I had updated about the same time I noticed it, so I attributed to that) the more I think about it now, if updating doesn't change its behavior, this is probably what's going on.

Thanks. I am on UVALH2. I think the way it is supposed to be setup is to sit on UMTS while conserving bat/data and switch to HSPAP when moving data (Both WCDMA protocols). It actually has been much better today. Don;t know if the tower in my area was having issues the last few days.
I checked for NFC programs that would allow me to change my networks based on location and none have that fine level of settings.
It isn't really a problem if I switch it to WCDMA only, it's just that I forget to switch it back to both when I'm on the road and I end up missing calls.
Well, I guess that answers whether it was the update that did it for me! I'm guessing it must be due to the network refarming then. Like I said, it did the same for me for a while, but I haven't had it hapoen at all for some time now.
You could look for an app that lets you create location based profiles. You can set it to be one way at home and when you leave it'll automatically change to your other settings.
I would imagine Tasker could handle this as well, but I've never used it.

Wondering if anyone else is having issues connecting to a 5ghz network? I wasn't able to get it working, wouldn't even show up in available networks. That was stock out of the box, and after flashing a couple ROMs. I'm using slimbean now and am able to connect, but I have to turn WiFi on/off several times on the n7 before it shows up and connects. My s 3 connects no problem.
And I've tried all the standard troubleshooting on the router. Even changed some settings on the 5GHz band.
So if someone could double check for me that would be great!

5ghz works great for me. Reception is the best I've ever gotten on that band. Currently on stock, but it's worked in CM10 too
The 5 ghz didn't show up for me either. Had to manually enter the SSID and it connected right away.

On the first boot it didn't show my 5GHz WiFi, but after I connected it to my 2.4GHz, it immediately downloaded an update and rebooted itself. When it came back up, it saw my 5GHz.

Mine didn't at first either, but after update/reboot no problem. Now connecting at 150meg on 5ghz.

Still hit or miss for me. Sometimes its connected when I reboot. Usually I have to toggle WiFi on/off 2-3 times.

My Nexus 7 connects to my 5ghz router band all the time. I think it actually prefers it. I'm using it right now.
Sent from my Nexus 7 using xda premium
Well I think I have it working. I gave the n7 a static address and now after a half dozen reboots its auto connecting every time. I tried changing channels on the router. Tried 20/40 MHz channel width. Ticked on/off all the options on n7 WiFi settings. Nothing worked. Then I set static address on my tablet and router and like I said so far so good.
I'll update if there are any other issues because doing a search showed a lot of other devices having this issue. But none of the results recommended setting a static address. Maybe I got lucky. I could use my 2.4GHz network reliably but I want full network speed since I only have the 16 GB model and do a lot of folder syncs to keep my SD storage free.
Edit: scratch that. Worked half dozen times in a row. Rebooted after I wrote this and it didn't connect.

During initial setup i was not able to connect to my 5ghz but i was able to connect to my 2.4ghz. After setup was complete i was able to go in and switch it manually to the 5ghz network. If i power the device off and turn it back on it would not connect to my 5ghz or my 2.4ghz. I then went into wifi advanced settings and switched to 5ghz only and it connected immediately to the network and hasn't lost it since. This was true before and after the update, i am stock, unlocked and rooted. I also do not broadcast my ssid.

If I am connected to 5ghz and go in advanced and select 5ghz only, it disconnects me from WiFi. It will still show my 5ghz network in range with good signal but if I now try to connect..it does nothing. Keep clicking connect and nothing happens. Then go back and put frequency on auto and the 5ghz disappears. I then have to toggle WiFi 4-6 times before it connects again to the 5ghz.
Strange.

I had the same problem at first too. Here's what solved it for me: set 5ghz frequency to 20mhz instead of auto, change the channel from auto to any number you want, 5ghz will most likely be completely clear in your area so just choose any channel. After doing that it should see the 5ghz network every time and connect automatically.

Same issue here. But i have to restart my device. Is it hardware or software you guys think?

I'm not sure. Seems like software to me because once its connected it stays connected. And the signal range is really good. Better WiFi than any phone I've ever had. Better than my laptop too. My s3 has no problems connecting. Even with all the router settings I've tweaked its never had an issue connecting with the s3.
Are you able to connect?
In another thread someone noticed his WiFi settings were set to Europe. He said he hadn't changed them and that he was fresh on stock (his first time booted). Double check your settings if you're still having issues.
Settings | WiFi | advanced | WiFi region code.
Mine was also set to Europe as well for some reason. If your router is setup to use a channel not available in Europe this would cause the problems described here.

Update..powered on after a few hours and it did not connect to 5ghz. Went in to the advanced settings and switched from 5ghz to 2.4 and back again and connected right away. Will try the region code, to see if it helps.
update to the update: flashed vanir 4.3.081213 and wifi connected to my 5ghz right away and has continued working through two reboots so far. On stock rooted 4.3 i had to toggle wifi frequency to get it to connect after every reboot.

OK guys, I think I have as real solid lead on this bug. I'll update with some info a little later, I want to test this some more. But for now I'll say that I made some changes and I have had zero disconnects or problems connecting while toggling or after reboot. And I mean 100% connection rate after 50 toggles and a dozen reboots.
Till I can get the info up, one question for you guys having the same issue. Do you have multiple routers in your network and/or custom firmware on your router?

For some reason when my phone goes to sleep it will wake up and be stuck on edge or gprs. This seems to only happen in one particular location. I tried a different apn but this didn't fix it. I'm wondering if it's a phone issue or a network issue. This seems to be a rather new problem.
Do u have any profile application that sets your network mode based on the location you are at?
Does that particular area have 3g? Have u tried it on another phone?
