I'm on CM dal .32 test build 3.1
Today I tried setting up a VPN but failed. The screen became frozen and I decided to reboot my Nook Color. However, after rebooting my wifi is no longer working. It says "connecting" but then "disconnected" Scan option didn't show any network.
Anyone can help me?
CM7.0.3 with Nook Color no longer works
Hi,
I've run into the same issue with my nook color. I'm not sure if this is an issue with the kernel or the physical device. I know that this is not a router issue since I'm able to connect other machines to my router. Also, I no longer see any other hotspots with the Nook.
I tried some suggestions that I've found on other websites, which include
Shutdown Tablet and start again
Re-install Google Apps
Use Fix Permissions in Rom Manager
None of these work. Any suggestions or is this a known bug?

Same here, I was using nightly 115 with Dalingrin's 6/18 OC kernel when the problem started. I've since rebooted multiple times, fixed permission both from CWM and in Rom Manager, flashed nightly 117 without flashing OC kernel, and still haven't solved the problem.
Wifi just stays "Connecting" and then changed to "Disconnected" briefly and go back to "Connecting" again.
Just reflash your ROM or the latest ROM and DON'T mess with any OC kernels.
Does it work? If so, try the OC kernel again. If it fails, let Dal know in his OC kernel thread, and just re-flash your ROM again to return to the stock kernel. Wipe cache/dalvik as necessary, but don't wipe data and you're not going to lose anything.
One suggestion I have is if you're using AES on your router, try changing from WPA2 to WPA or changing WPA AES (or AES+TKIP) to just WPA TKIP and see if that fixes the problem.
There's a long standing issue with some routers regarding AES in Android, and apparently some laptops also had this issue on older kernels.
Flashing to the latest rom without messing with the kernel was the first thing I tried (other than turning wifi on and off multiple times). It didn't work.
What eventually worked was when I wiped data and factory reset it. Some how that fixed the wifi.
The strange thing is I had just recently factory re-setted coming from an old (pre 2.6.32) nightly a couple of days ago, and had not gotten around to installing much, and I did not restore from backup. i.e. the only thing installed when the wifi problem suddenly appeared were the google apps, Aldiko, QuickPic, Rom Manager, MoboPlayer, and a few ADW themes. None of which sound like they should do anything that messes up the wifi.
I doubt it has anything to do with the router, because I tried connecting it to my router (tkip), hotspot from my android phone (unlocked) and hotspot from my iphone (unlocked). My phone just did not see any network around at all, not even the 5-6 different network from other people in the building.
As mentioned, I have factory wiped my NC and all is fine again now, so I'm not too concerned right now, just curious what could have caused the problem.

I just finally got sick of waiting for an official Froyo(Bell isn't about to give me an upgrade anyhow.) So I went to a froyo rom that was based on one of the stock roms. But I figured since I'm rooted anyhow why not play around, and grabbed cyanogen 6.1 and installed it. Then I end up with the issue of its not connecting to my wifi, I have no issues on the stock 2.2 roms. One thing I have noticed is the cyanogen shows the network as wep, but it's actually wpa encrypted. I flashed into it from the stock without clearing it first and it worked until I shut off and came back to it. Any ideas on what might be the issue. I'm fairly new but I did look and couldn't find anything to fix this.
I assume you flashed 6.1 stable version? I have no issue whatsoever on my device (and I also used official froyo previously). Did you wipe all before flashing 6.1?
He said he "flashed without cleaning"...so I presume no wipe. This could be the problem, a wipe is strongly adviced if going to CM from a non CM ROM. Also check the number of WiFi channels set by default in advanced settings of wifi. It is set for 11 and if the router is set to 13 or 14 it could not work

I had the same problem when i was installing CM6.1. (with wipe)
The phone could just se a wep version of my network and not the wpa that i have. But after i turned on and off the wifi a couple of times i suddenly saw the wpa version of my network and after i connected to that the problem was solved. I also did click "forget network" on the wep version.
Hope this will help you

Trying this now but no go. Sometimes will flash it as wpa and then jump back to wep. This is after a full wipe. What I was trying to say was once I flashed in without wiping and it worked for a bit but jumped right back to not working, after the phone going to sleep.
Bump.
Any insight into this issue? Still only reading my network as wep.
Try installing "WiFi Advanced Configration Editor" from the market. You should be able to change to WPA manually with it.
Did you try to reset your wifi router?sometimes the issues came up from wifi router, not the phone itself.
Mine is fine. I share my broadband wifi to my phone using connectify.
The only problem remains is wifi disconnect frequently, but I heard that it's due to a new kernel which I use (.32 kernel)
hope it helps
Ya reset the router a few times, and it still came up like that. I did install the wifi advance config software mentioned it seemed to fix it. I didn't actually set anything up on it and it seems to have fixed it. Thanks.
CM 6.1 messed up my wifi. Wiped everything, but it suddenly doesn't find my networks.
Wiped again and restored nandroid backup of working rom but STILL the same issue now!! Can I flash the wifi drivers again somehow?
I recently bought a nook color and flashed CM7 to the internal memory. It worked perfectly for about 2 weeks. Then the trouble started. My wifi would not connect. It would get to the point where it would say, obtaining IP address, then begin the process again without ever actually connecting. So i decided to try to reinstall CM7 hoping that would fix the problem. I attempted this, and to my disappointment, the nook wouldnt boot past the green cm7 logo. I reverted to stock from a backup i made initially, and the nook booted just fine into the stock OS, but the wi fi still would not connect (doing the same thing as in cm7). I reinstalled cm7 and again was greeted with the same boot issue as before. I then followed the "dummies guide to fixing my nook wont boot" and returned it to the stock image and reformatted the data and system partitions as the guide states. I then (again) flashed CM7 (nightly 134). This time, it booted as it should, but the wifi still will not connect, and also the softkeys are not present. In settings, if i select the CM7 settings, i am given a force close notification. I am beyond frustrated at this point and would greatly appreciate any help.
Thank you
I have the same problem with my wifi. It's really weird. It was working last night, then I backed up the current rom and when it rebooted the wifi wouldn't work again. I'm about to just remove cm7 because I don't have the time to fiddle with trying to figure out how to troubleshoot it. A buddy of mine at work is the one who flashed it for me but it hasn't been a great experienced. Rom Manager also doesn't show an updated version of cm7, I think the one that is flashed on my NC is like from may 25th or something.
idk what the hell's going on with it...i cant get it to work no matter what I do and it's driving me crazy. I posted here and on the CM7 forums and havent gotten any help yet, nor have i seen anyone else with the same problem (aside from the above poster).
After a few days running Dlev's 4.2 ROM, my wifi stopped working suddenly. When I try to turn it on it says error or unable to start wifi. I've exhausted several initial options I began walking myself back through various ROM's back to the original 2.1 stock ROM. Without success I even performed a master clear and several reflashes of the orininal stock ROM, nothing is working. I tried FXR Wifi fix and rescue. Does anybody have any ideas on what I should do?
Thanks,

Kernel?
What kernel were you running with the custom ROM? Talon's being updated really frequently, so if it's Talon, you might try the latest version of that (0.4.4.22, as of this writing)

Did you try rebooting your router or device that gives you wireless signal? also see if other devices can connect.
It was Talon 0.4.4, but I've gone all the way back to stock ROM/kernel etc and that makes me think that this is a HW malfunction.
AT&T had me reboot the router too, my laptops are able to connect just fine. It's not really a connection problem either, Wifi will not turn on at all.
I called Samsung and they want me to ship them the phone, still debating that one since I will have to go without a phone.

Hello everyone,
I flashed CM 10.1.2 with build-date 2013 Jul 11 and I can't activate my WiFi anymore.
Bluetooth is ok, but I can't disable NFC - same as WiFi.
I push the button and it's "working" to activate wifi or deactivate nfc - but nothing happens. [edit: nfc working after reboot]
I've got not many ideas what I can do. Everything is working fine with the stock rom v.20a EUR_Open.
Has got someone an idea what I can try?
I did every step on it's own to have a look on which point the problem appears - after installing cm 10.1.2 with cwm recovery.
Bootloader is unlocked.
I'm looking forward to your suggestions and please accept my apologies for my bad english.
Kind Regards
FChaos
For nfc, just restart once, that will fix it
Hey,
im having the same issue with wifi.
When i try to activate the switch gets stuck in grey but it does not activate.
I have it since I installed CM 10.1.2 stable. Before everything worked just fine.
Any solutions for this problem?
Greetz
Wipe cache & dalvik cache
Fix permissions
Reboot
If that doesn't work then full wipe and reflash.
Note: WEP encryption will not work with CM v10.x so make sure you are using WPA on your wireless networks.
I already tried everything you mentioned, but nothing works for me.
WEP is not the problem, because I can't even get to the point to select my router. Also I'm using WPA2 at home.

I presume the CM build you refer to is a nightly? Try a different one or CM stable - nightlies are a beta software and may have random bugs.
The problem occurs since I installed the CM 10.1.2 stable.
After that I also tried some of the new CM 10.2 nightlies, but the problem still exists.
Any other ideas?
Edit:
When I install Android 4.1.2 Stock everything works just fine, but the moment I install CM wifi does not work anymore.
I have had this problem ever since I installed my first rom (FreeXperia unofficial cyanogenmod 11) and stayed ever since
The problem is that every time I try to connect to my home network it will say "saved, secured with wpa" but never connects.
so far I have tried:
Forgetting and re-adding
Factory reset
Flashing different kernel
Flashing different rom (Vanir and official AOKP)
unchecking wifi-optimisation
changing region.
Non of these work, somebody please help me figure this out
P.S it also happens on WPA2 but less.
