Hi guys...
there's a way to improve Wifi reception for our Gtab? I have a Lg P500 and it's wifi reception is much powerful than gtab 7+
In the same place lg takes the signal and gtab none
i had the same problem. in a forum i read about channels of my router.. if you put your router on auto channel, it might choose a channel that doesn't work as they should in yout tab
solution?
put manual channel on the wifi radio.. from 1 to 7. i choose 7 and my issue with wifi just go away.
cheers
Just a small bug I encountered when using Katkiss. It seems Katkiss with EMEA etc. can't discover a wifi router which is using channel 13.
It did find the wifi after I changed the channel of the router to 6 or something.
Change wifi regulatory domain in wifi advanced settings
I've two WiFi set in my house.
WiFi 1 in channel 13 and WiFi 1 in channel 6. Each router is separated, both have same SSID, encryption, security password, etc..
On my nexus 5 I've no problem, phone switches to the best signal in range router automatically. One plus one just connecting to channel 6 router but not working with channel 13 one.. I've tried changing WiFi region to USA but no luck.
I enter WiFi passphrase and it tries to connect so fast I can't even read text. Then it's says "saved secured with wpa2". I've already tried to forgot WiFi, reboot device, etc..but no luck.
Any idea?
Changing the Wi-Fi setting to USA would make it NOT connect to channel 13. It would only connect to channels 1-11.
Try changing the country to one that supports channel 13 or just change your router's Wi-Fi channel to a USA supported channel.
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.
Hi all,
I have had to hard code my 5ghz WiFi router channel to get my Chinese tablet and ROM (zui13) to connect. This is mentioned on other threads.
I noticed that with the 5ghz channel out of range, the tablet would also not connect to the 2.4Ghz channel with the same ssid.
I was wondering if anyone has found a workaround on the tablet to get the full channel range working. I don't want to risk changing region and breaking widevine or anything else, neither do I really want to hard code the 5ghz channel - the lower range are unavailable and are the best choice for my environment as no other use nearby from neighbours.
Any ideas?
Would love to know this too. They really do not want us ROW people buying up great value hardware without some teething pains do they!
Can yours detect Wi-Fi in your neighborhood?
If so, try different channel on your router or AP to see. You can unhide your SSID to see does it connect
As far as I know without access to the kernal source we cant change the available wifi channels to the chinese rom even with root.
So without the region cuange i rhink yall out of luck.
That is weird. I have no issue with both 5ghz and 2.4ghz. I can connect to both without issues.
