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

Thanks. Does sound like just me then
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’m struggling with my Xperia Z3 these days. It’s because of the WIFI speed issue. This happen suddenly when I access the internet through the WIFI connection. Internet speed is really slow in Chrome Browser, Facebook and other applications. But the thing is when I use the ookla internet speed test I got my full bandwidth in network connection (20 Mbps +). And I tried to update my apps through the google play store. Sometimes it’s not updating. Sometimes its download speed is 100/200 Kbps. And i enable my mobile data and disable WIFI connection. It works really well in mobile data connection apps also works charmly. So I have tried couple of things to solve this problem.
1. Clear cache + data in Google Play Store -> Not fixed
2. Re install marshmallows firmware -> Not fixed
3. Rollback to the KITKAT version - > Not fixed
4. Install WIFI analyzer -> Seems okay instats
5. Disconnect and connect phone to WIFI router -> Not fixed
6. Connect to my other WIFI router -> Not fixed
7. Change WIFI settings in phone -> Not fixed
8. Create WIFI hotspot using another mobile phone and connect to the hotspot -> Not fixed
But my issue is still exist. It's really weird. My other mobile phone works well in same WIFI network. So i really need to solve this problem. I'm really appreciate someone can help to my issue. Thanks.
Note: i'm not a native english speaker
Anyone knows about this issue?
Just found a clue
I've installed "Super VPN" to my mobile and i saw my WIFI connection become stable but internet speed is still slow. When i install app from google play store it downloading without drop the download. But 100/200 Kbps constant speed. Another option I've tried again yesterday, but i was done this before. Add google DNS (8.8.4.4) to my WIFI network. Then it getting more that 100/200 Kbps but not constant. Well i don't know the exact reason.
But i'm using Customized UK firmware version. But i'm living in south asia.
Router settings perhaps?
Does you router have a 5ghz wifi option? because I sometimes have the same issue when using 2.4ghz wifi, while 5ghz is always fine
@mantin36 and @bookworth I've two WIFI connections in my home, so both have same issue. Also I've tried every channel in one router. Still not solve this issue. Both routers are 2.4 Ghz. But the thing is this phones WIFI connection worked before like solid. After couple of days from the purchased date this issue happens. Any idea?
Hi everyone,,
I'm having problem with my phone "UMI ZERO" , when I first purchased it it was working fine but after a year I noticed that Bluetooth isn't working properly, after a while the wifi started to disconnect and some times work but at 1mb/s even though my router supports 20mb/s and it works and connects only to a specific WiFi connection in my house, if I tried other WiFi connections it either doesn't connect to it at all, or connect to it but the connection speed is 1mb/s only even if the WiFi router supports higher speed.
I tried to format the phone and installed some WiFi apps but no luck!
Can any tell me how to fix it ?
Thanks in advance..
????????????
Hi,
I bought 2 months ago a Bll-l22 (BLN-AL30) build BLL-L22C636B384 and everything went fine... until I use wifi sharing (I use it all day long in my work). Back to my house, I experienced a really slow wifi connection, in download only : about 0,9Mbps in download max vs 10Mbps in upload (about 100Mbps up/down with my surface pro on the 5GHz channel). I can't even stream a low-res video from my NAS to my phone in these conditions.
The seller sent me another BLL-LL22 (BLN-TL10) but I experienced the same problem. Since it doesn't to be a problem from my wifi router (no pb with others wifi devices) nor a hardware (same pb on 2 differents devices), I wondered if it's a software bug : I resetted my 2 phones to factory settings and both recovered a full working wifi... until I use wifi sharing with them.
Does somebody experienced the same problem, and if it exists, is there a custom rom with full working stuffs for this phone ?
Thanks !
Same wifi problem here

hey, i got the samed problem here, any solutions?.
i had the same issues. used smartphone as hotspot for my ipcam at home for whole day. then connection wifi from phone had become throttle down. even the internet is much faster and my router had no problem with other devices.
i tried restart and on off wifi few times. but no luck.
all i did was reset network setting
then its back to normal again
hope this works for you too
wifi not using connection to router unless I turn on airplane mode in phone.
see EDIT at bottom of this post...
LG Stylo 4 Plus, stock ROM, no mods.
router is SBR-AC1750, connected to comcast @ 200Mb
in router, set up wifi connection over 2.4Ghz called xxx
In phone connect to xxx.
Ookla speed test app says maybe 5Mbps - about what I would get OTA.
Turn on airplane mode,
re-turn on wifi connection to xxx.
Ookla says 37-40Mbps.
What am I doing wrong.
It is as if it is using/trying to use OTA, - even though the SIM is removed for this test!!!
Acts the same way with SIM in.
Note, addy the same in wifi/advanced in either situation, but when in airplane mode, phone will see somebody's samsung, and my roku.
Behaviour seemed similar on one of my Moto X4's though I didn't pursue it endlessly.
Mod move if necessary but there is no appropriate Stylo 4 forum and nobody on the X4 forum would know. BTDT.
EDIT: I just changed from the 2.4G to 5Gbps router output and (without airplane mode) speed was 137Mbps. ASTOUNDING!! - so I can use this and yes, this is a fix(normal use range is about 2'), but wish I understood why it is so slow/problematic on 2.4G ???
EDIT2: I played with settings in router for 2.4Ghz and used g,n and 40Mb and improved things (Ookla) to about 30Mbps, but switched back to 5Ghz and immediately got 105Mbps. So I don't understand it but I will mark this solved.
Thanks all.
