I'm having an issue with my wifi on my S3, but only with one AP. We just installed a Cisco Aironet 1024 AP at our church, and initially my phone connected to it without problem. I've been doing some work on trying to get it configured as I want, and now my phone has issues connecting to it. What is strange is that my tablet and laptop both connect with no problems.
Here's what's happening. The AP is broadcasting on both 2.4 and 5 GHz bands. My tablet doesn't support 5 GHz, but connects to the 2.4 GHz band just fine. My laptop supports both and connects to both fine. For whatever reason my phone doesn't see the 2.4 GHz band, only the 5 GHz one. It will connect to the 5G one fine, but then it drops and reconnects repeatedly. My phone connects to both my 2.4 GHz and 5 GHz bands on my router at home just fine.
I'm assuming there's something screwy with the way my AP is configured at the church, but it still seems like there's something screwy going on with my phone. I've tried deleting and re-adding the AP, I've tried a factory reset, and tried restoring my nandroid. None have solved the problem. Anyway, I'm at a loss here, so do any of you have ideas of what I'm missing? What could be causing my phone to have issues with this one AP when all my other devices work just fine? I'm currently running CleanROM 5.0 with KindaCrap Mods installed. Thanks in advance!
Hi.
I bought a Western Digital N900 (N750s are not available in my country) as recommended by some people in the GeForce forum since it apparently streams well but I always get disconnected from Limelight every 20-30 minutes. Frames start dropping and I'm kicked out. A quick reconnection fixes the issue for a while. I'm like 2 meters away from the router with no walls in between as I was testing it. So I'd like to ask for suggestions on how to improve the performance. If you don't count the getting kicked out, it's smooth.
Setup:
Router A with Internet is connected to PC through Wifi (In a different room and floor)
Router B (N900) is connected to PC through Ethernet (Only Shield and PC are connected).
N900 uses same SSID for 2.4 and 5 GHz
I have tried using different SSIDs for 2.4 and 5 GHz but issue remains.
N900 Smart QOS is on.
I used Wifi Analyzer and I picked the best channel for 2.4GHz and I'm the only one in the area with a 5GHz router.
5 GHz is set to 20/40 MHz Auto (There's no 40 MHz only).
Limelight (rooted) is set to 20 720P/60fps.
Shield is using latest update and rooted.
I've tried normal Gamestream but it's choppy due to 30 FPS and there are weird audio sounds at times.
Is there anything wrong with my setup? Any tips to fix my issue?
I have a 2.4/5GHz dual-band Wireless-AC network at home that my Nexus 5 connects to just fine. At work there are various wireless gateways that run at 2.4 GHz that my phone can also connect to just fine. However, the main work network, which I need to to connect to is a 2.4/5 GHz network with access points all over the building and my phone just refuses to connect to it. It will say 'connecting' for several seconds and then go right back to 'saved'. I have tried disabling and reenabling my wifi, I have tried forgetting the network and reentering the password, and I have even tried setting my phone to 2.4 GHz only (since I had heard something about Nexus phones having strange issues with 5GHz networks), but nothing has worked. I really need to get my phone on this network, so I'm hoping someone can help me.\
In case it's relevant, the 5 GHz band of the work network is on channels 36, 40, 44, 48, and 157, and the 2.4 GHz band is on channels 1, 6, and 11.
Hi all,
Strange problem following my OTA lollipop update yesterday. My (UK WIFI version) Shield tablet is unable to detect my router's 5ghz signal. Kit Kat had no problems and all my other devices can still see it fine. I have also tried changing the settings on my router to see if Lollipop is more fussy about frequency/band etc, but still no joy
Anyone else having strangeness with this? Or is it just me?

I flashed the US ROM last night, and during setup it took maybe an additional 20 seconds before the 5ghz routers (including mine) to show up in the list. 5ghz has always been kinda weird for me though. On a few occasions I've had to disable WiFi, wait 10 seconds, then restart so that the tablet will connect.
I also have the UK wifi version, and my tablet even connected first to the 5ghz network, I was actually surprised.
No issues here with 5ghz wireless.

Thanks guys,
It's very odd, because I run wifi analyzer at home and it doesn't show my 5ghz network at all, yet in the office it does show the 5ghz one.
It was working before the update and all my other devices can still connect fine, so a real mystery

Reboot the router?
I'm having this issue with my Nexus 4: http://forum.xda-developers.com/nexus-4/help/lollipop-5ghz-wifi-t2945330
Upon further inspection, it appears the only 5ghz channels that work are the first couple in band A (36 - 48) Nothing else seems to work.
Can anyone else confirm this behaviour? Try using a 5ghz channel other than 36 - 48
Band A : 5150 - 5350 MHz (channels 36 - 64)
Band B: 5470 - 5725 MHz (channels 100 - 140)
This is pretty rubbish if this is the case, as the band B channels allow a higher output and give me a much stronger signal in my house

I can only connect when I use channels 36-48, Band A UNII 1. Can't even detect the AP with WiFi Analyzer on the shield if I go above 48.
Using the non-US 32GB LTE version in the EU, btw, same frequencies are allowed here as in the US.

Sorry, you're right 48 does also work.
So that's confirmed then, they have for some reason heavily limited the 5ghz channel selection! I wonder why?
It's not a hardware limitation as it was working fine with KitKat, so I wonder whether it's possible to get the other channels unlocked?
Just to be sure, ClownShoes, does channel 140 work for you? I can't test this because my fritzbox router doesn't have an option to change channel width to 20MHz, and channel 140 isn't available to me for this reason.
Same problem for me here. No 5ghz detected when my Xperia Z1 Compact detect it . Even Wifi Analyzer can't see it . I restarted my tablet & stuff, nothin' . I'll try to make a nandroid backup, make a fresh install and I will see the result.
Same problem for me here with my samsung galaxy note 3 32 gb(sm-n9005). If I restart router phone view and connect to 5 GHz. When phone leave coverage are for same hours when come back don't see 5 Ghz wireless. This is strange because I have another phone with windows which work perfect. I will try to change wireless channel if don't work, I thing serious to go back at android 4.4.2
Update: I changed channel from auto to 48 and works.
Just dropping in to say I had the same issue: I had my router on channel 112 and the Tablet wasn't even seeing it.
Switched to 48 and everything works fine now.
Same issue here, hoping Android 5.1 fixes this silly issue. I was wondering why i couldnt see the 5Ghz network at channel 140, 80mhz. had to bring it down to channel 48.
US wifi version here. 5.1 Lollipop, stock rooted.
I can connect to channel 149 with turbo mode (40MHz channel width) & the upper Extension channel, but WiFi analyzer shows my router is broadcasting on channel 153. I tried so many other channels & combinations but this is as high up as I could go & have the tablet connect. It did, however, see channel 161 but got an authentication error & wouldn't connect with the router.
So, back to 149. The signal is slightly stronger & have better throughput than channel 48!
On a side note...I use 5GHz here in this LARGE apartment complex because everyone here is on Verizon FIOS or Cox Communications, so Wi-Fi Analyzer sees 17 (give or take a few for signal strength or weakness) access points around my place & the 2.4 band is completely choked up! There is only 1 other router close by on 5GHz, so using that band is the only option for wireless internet here. I don't use Verizon's wireless AP. They only have 2.4 wireless, no 5. My Netgear simultaneous dual band router is plugged into the back of their cable modem & my Netgear is on 192.168.2.1. That way I can use DD-WRT & my own router instead of theirs for wireless. Easy-Peasy!:good:
I have the same issue. After switching my channel from 100 to 40 the 5GHZ wifi showed up on (two) shield tablets just fine
I believe the SHIELD Tablet only supports United States Non-DFS channels, so 36-48 and 149-165. I personally have mine on Channel 149 and 80MHz bandwidth.
I have an ASUS wireless router, and my wi-fi connection at home is dropping all the time (especially while playing Hearthstone, frustratingly). Is anyone else experiencing this and/or know how to fix it?
My experience has been that the wifi on my phone works great, leading me to wonder about either your router or your environment.
questions and things to try
1. Does you phone work well with other access points? i.e. is the problem only at home but it works elsewhere?
2. is your home a "noisy" wifi environment? i.e. lots of other nearby access points or other devices in the 2.4 Ghz band?
a. Get an app from the play store called Wifi analyzer (its free). You can see a chart with all the access points your phone can see and what chanel they are using. It can show both the 2.4 and 5 Ghz bands.
b. If your router is showing up on the same channel or a nearby channel as one or more other access points, try manually setting the channel on your router to something else that no one else is using or near.
c. If you router is dual band (i.e. has both 2.4 and 5 ghz) and you are using 2.4 Ghz, try using 5 Ghz. You can set your 2.4 and 5.0 Ghz to different SSID's (network names) so that you can easily tell which one you are connected to.
3. Do other wireless devices you have also have connectivity problems? Consider a new router?
I had problems with wifi dropping. I went to Comcast and swapped out my modem for a new modem/router and haven't had the problem since

I've had very poor speeds on WiFi compared to my nexus 6p. Annoying it's so slow

I suspect the issue has to do with my Asus router. Apparently Samsung devices and Asus routers don't play well, according to what I've read, but I have no idea how to fix it.
