Wifi just scans and never connects

I just upgraded to 5.1.1 ...I posted an update http://forum.xda-developers.com/showthread.php?t=1008702 to my post but assumed most never saw it....
anyhow....ever since moving to the update my wifi just spins. It recognizes that there are services available but it never gives me an option to connect to them. Any ideas?

after a sleep? or after upgrade to 5.1.1?
I have encountered this issue before on tnt lite 4.2. I simply rebooted it and reset your wireless router. and then no issue to me.
check out this thread if it is after a sleep.

I don't 100% remember but I think that there is a custom kernel to fix/improve the wifi problem? Anyone can confirm it?

There were some issues regarding sleep (mostly failures to wake, causing reboots, and CPU throttle getting stuck on sleep).
However, those on the 5.0 TNTl are stuck with the existing kernel. Not to bash TNT - I've used 4.X and 5.X versions and think its great - just that it's in its own little world as far as kernel and recovery options.

no sleep...just straight after the update. I have searched the forum and done anything that looks like it might work. Reset the router several times, stood within 6" of the router. Re-booted probably 100 times.
I went back and cleared the darvlick cache and did a factory reset. Re-installed 5.1 thinking this might help but from my noob eyes it looks like 5.1.1 is still running (based on the background wallpaper only).
That is the frustrating thing for me...if this happened on my pc I would go get a new driver or reinstall the hardware and I would be back up and running...with Android and ROM I am completely lost.
++UPDATE++
Just checked into the hotel and the wifi works on an open connection. I really don't want to open my home network if can avoid it...typical suburban cul de sac with too many people that would to steal some wifi

Issues I'm having with CM12/ OS12 - WiFi and Swiftkey

Hey guys,
So I installed CM12S using the tool provided so I believe this was a clean flash.
I did come from a custom CM12.1 rom so Idk if this is the reason I'm having any of the following issues.
WiFi - It says I'm connected however I know it isn't working because I stop getting whatsapp messages...it works at first then stops unless I disconnect and reconnect.
Swiftkey - It can't seem to connect to Gmail, keeps failing.

[Q] Connectivity issues on Nexus 5

Hi,
I have serious connectivity issues with my Nexus 5.
Most of the time I am only picking up 2G signal, sometimes the connection drops compeltely. However, I had a very unstable 3G/H/LTE connection for a few minutes sometimes in the last days.
This started after changing the battery and upgrading from Cyanogenmod 12 to 12.1. Unfortunately I did both changes at the same time, so I am not sure what caused this problem.
The following things I could rule out/test:
- Another phone (Nexus 4) picks up H+ with my sim
- My phone doesn't pick up 3G/H/LTE with another (working) sim
- I have checked the connections of the both cables running alongside the battery, I also checked the cables itself.
- I fiddled with the apn settings, also I never touched them before and everything worked fine.
- I have updated the radio image.
The one thing I couldn't try is flashing an older cyanogenmod 12, because I have no backup and couldn't find one online.
Does any of you have any ideas what I can do?
I would be really thankful for any kind of help.

Who is your carrier :/

I probably should have added that in the first place.
My carrier is T-Mobile in germany.

I have the same problem. Also i'm tryed flash Android 5.0 and Android M, in stock i have Android 5.1.1. Who khow how to fix this ?

I have no solution yet. The next thing I want to try is to roll back to Cyanogenmod 12, but I guess I am going to build it myself because it seems to have vanished from the internet.
I do occasionally get LTE, but it is very unstable and doesn't work most of the time.

Wifi gets disconnected/stops working

Hello all,
I have faced issues with the Wifi on my OPO since the day I got it. I researched a lot about it and found out that it's a problem faced my a lot of OPO users. Just to summarize the problem: The Wifi connects but after a few minutes (in sleep and sometimes even when the phone is in use) the data transmission stops. The Wifi icon shows that it is connected but you can't access the internet.
I had this problem on the 11s and when I read 12s had solved the problem I moved to 12s. But the problem still persists. Here are the things I have already done:
Wifi in sleep - Always
Restored factory settings
Installed app WifiKeepAlive
Installed 12s (15th Aug build)
I have seen a lot of posts but haven't seen a resolution in them. Appreciate if someone could help out.

I used to have a similair problem on my old One until it broke due to water damage. My new one doesn't have this however.
Perhaps a kernel issue? Try flashing a different one and see if the problems persist.
