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.

My P6800 has a wifi problem . sometime can not find wifi channel 12,13,(14). in Korea we use 13 channels.
your Access Point set channel 13 and open wifi analyzer(app) and turn on and off WIFI of P6800,
in my case sometimes 6800 did not search channel 12,13(,14).
how to solve this problem?
So, after browsing a bit about this I'm still unable to connect to my work wifi network. Every other network I'm able to connect just fine.
I put the wifi password, authenticates, goes to "obtaining ip address", goes back to authenticate.. and doesn't connect.
Forcing (using manual IP configuration) connects but doesn't open websites, even tho I'm using the connect gateway / dns servers. (even used 1st dns same as gateway).
Got a LG 4x next to me connecting just fine, problem is only on my nexus 5.
So far happens on 4.4.2 and 4.4.3.
Tried some tips that I saw around the web like disabing nfc or turning on and off airplane mode (although there isn't much logic in these), but still nothing.
Wifi password is correct.
Problem it seems is somewhere obtaining the ip from the router or something, as it goes back when it reaches this point, but then again forcing it allows me to connect but doesn't open websites.
Any tips? I'm suing WPA2 PSK at home and it's fine.
The network is in a 2ghz range channel 10.
Any help is appreciated.
PS - Router is a linksys WAP54G.
Thanks a lot!
Dear XDA members.
I purchased my D820 Nexus 5 a couple of days ago, connected to my home router to set things up but then I noticed something, the device is connected to the router in every single room in the house with at least a fair-strength connection but I actually don't have Internet access unless I'm about 6-10 ft away from the router which is a bother.
Things I tried:
-Restarted router
-Connected to router using other devices
-Edited router settings flipping between 802.11 b/g/n bands
-Changed security type and encryption
-Used a static IP connection instead of a DHCP
-Installed two different roms to test the connection (CM11, Mahdi)
-Installed Wifi analyzer,apk to check surrounding traffic (to avoid wireless interference) and then changed router channel to a suitable one.
I have searched loads of websites and haven't found any working solutions, I'm so desperate for help.
Sorry for writing a long thread and thanks in advance.
Frogi.
In your phone's advanced WiFi settings there is the option to choose between 2.4Ghz or 5Ghz try those. If that doesn't work trying flipping the mobile data switch off and see if that helps.

What happens if you remove any security type and encription?
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 am using a router which broadcast both 2.4ghz and 5ghz band using single SSID. how do i force my phone to only allow to connect to the 5Ghz wifi network. i cannot turn off the 2.4ghz band as there are other devices in my house that only support 2.4ghz or do i want to split the bands into 2 SSID.
Thank you.
i was able to split my router to 2 different SSID for both bands
In the past there used to be an option in advanced wifi settings that made the 5GHz "preferred" but Google took it out for some reason.
The disabling of the 2.4 GHz or having 2 separate SSIDs might be the only way right now (not sure for a rooted phone tho)
Sent from nowhere over the air...
Yes not sure why did Google remove that option. Any hidden secret code i.e. *#00*# etc that allowed us to make changes to network setting.
Some routers have band steering which will force devices to 5ghz if supported while keeping 2.4ghz for devices that can't.

I turned off Auto Connect on my 2.4ghz, so it stays on 5ghz all the time.

Mine only 1 ssid for both band. Seem like there is no solution and i had to split the bands into 2 ssid.

I only have 1 ssid. Like I said, I turned off Auto Connect for 2.4ghz so it always stays on 5ghz.

thanks, but for me both the bands are broadcast into one SSID. which means i can only find one wifi connection and the wireless router will change the band connection based on the signal strength when i am moving around the house. it will change the connection to 2.4ghz when i am in some place where the 5ghz connection is weak. why i wanted to stay with 5ghz when the connection is weak because it give a much higher download/upload speed compare to the 2.4ghz connection which somehow got much weaker internet speed to the extent of unusable.

Buy a new router where you can separate them and then disable or turn off the 5ghz connection
Looks like this is quite an issue for N2Us. I have a 4 year old iphone and it stays connected to 5GHz in the same place and N2U reverts to 2.4. I have band steering and have been really well on all other devices. Issue lies only with N2U.

Mine can separate them but since it is only affecting my phone, I hope the change can be on the phone instead. By separating them, I will need to configure all those devices that can only connect to 2.4ghz. e.g. ring peephole
Did you solve issue? Same problem here :/

Errr...you actually DON'T have one SSID but 2. The band is appended on the name and they are actually 2 different WiFi networks with different names so you could turn off auto-connect on the 2.4GHz one
I use the Wireless Mac Filter on my router to block 2.4Ghz Band for my phone mac address, so the phone can only connect to 5Ghz
If you are using a Samsung phone in the advanced settings for wifi, turn off use randomised MAC address and use the phones actual MAC. This fix has been tested on Netgear routers and works, phone will join the faster 5ghz and still be able to switch to 2.4 if you are at a distance from the router

This is what i did .
(It might give you an very easy option /idea .)
My current setup is a Nokia fibre router that has 2.4 ghz and 5 ghz bands
I bought a reasonable priced wifi mesh 'TP DECO M4 "then
connected it to my fibre router ( ethernet cable )
The TP wifi mesh comes with an Android app fo configure it (settings )
All i did was swicth off the 2.4 ghz band in app, for my TP decom 4 model .
So if i wand to use only 5ghz i connect to my TP DecoM4 ( which is connected to my Nokia fibre router)
My othe devices( that only use 2.4 ghz bands ) i connect dirrectly to my Nokia fibre router, that has 2.4ghz band active ...and also the 5ghz ,
So fo me its a matter of to switch 2.4 ghz on and off in the Android TPlink app .
Hope this give you an very straightforward option ?
good luck
see screenshots below
Hi...
I don't if you already solved you problem but, probably, if you have router which broadcast both band with the same SSID you have option, in router settings, called SMART CONNECT set to the "ON"...
I found a solution that worked for me, i am using a xiaomi router and a s21
Samsung S21 Ultra 5G not connecting to 5Ghz wifi channel
Hi folks . I have a Samsung s21 ultra 5g. I can connect to the 2.4ghz WiFi but more than often I can't seem to connect to the 5ghz wifi channels .I'll have my laptop right infront of me onnected to the 5ghz wifi channel , yet my phone won't be able to the same. My router is netgear nighthawk...
