[Q] Wifi not connecting at all on CM10

I had the wifi issue on 4.0.4 too, where my ion wouldn't connect to my wifi after it got disconnected but it would have worked again if I put my phone into airplane mode, disabled wifi, then turned it back on, took it out of airplane mode and reconnected the wifi, but after I installed the cm10 it doesn't connect at all it can't even find my network. I've tried adding the network manually but it still says its out of range. anybody else having this issue? has there been a fix to it ?

my wifi on cm10 working great, had no problem since i installed cm10.
maybe you can try re-install cm10, better do clean install, wipe data, wipe cache, wipe dalvik and format system.
hope it help you.

Well I figured it out it connects if you change the region code in the wifi settings and that's great cause there's no need to reboot the device anymore every time.

WiFi not turning on?

Ok so a couple of days ago I installed a 4.0 ready radio on my galaxy s2 and then went on to install Jedi Knight 6 ROM (4.0.4 and radio is UVMC6) and after installation everything was working fine.. I was messing around for a while.. it worked today, I shut my phone off to charge it up real quick, and when I turned it back on my WiFi would not connect. Well not necessarly connect.. it just wont even turn on. When I go into settings and click WiFi, it just sits there saying, Turning WiFi on, and never changes.. I can't seem to imagine what could have happened to it, and I really dont wanna have to reinstall the ROM again because i just spent hours getting this one all set up to my liking...
Anyone got any ideas?
EDIT: BTW, I have tried many things.. Tried airplane mode to disable everything then turn it back on, obviously tried rebooting the phone, i have tried wiping cache in CWM recovery and also tried fix permissions in recovery (another topic said to try those..)
Nothing has worked so far, i'm about to try reflashing my radio, see if that works.. but I really really dont want to have to reflash my whole ROM.. So if anyone has any other ideas please help, i'll edit if the radio works..
EDIT 2: Reflashing the radio did nothing.. it's really wierd, the data, bt, gps.. all of it works fine, it's just the WiFi that's frozen turning on... cant get it to stop turning on and can't get it to actually turn on..
EDIT Final: Ok well, i guess nobody knows what might have been going on.. so I just wound up reflashing my ROM, which obviously fixed it.. i just had to lose all that time spent setting everything up... But oh well.. Kinda sucks nobody even tried to help..

+1 I'm going through the same thing now

I have been having this same issue as well. It started out as stock happening sporadically. One thread suggested rooting and removing my account. Problem still occurring. Tried flashing multiple ROMs and now WiFi hasn't connected at all always stuck at turning on. I have tried clear cache, fix permissions, as well as reinstalling ROM dirty and with factory reset. I'm hoping this isn't hardware failure because I just bought this phone used but it seems to be a reoccurring problem with others as well. Any NEW suggestions not given from quick Google/xda search?

I'd suggest to check your Wireless Access Point (modem or router) wireless settings for security, check and see if it's set to use WPA/WPA2, which is common on some modems/routers, change it to either WPA or WPA2 (preferred) not both, it's a known issue with WiFi networks and having it set to using both, I had the same problem before with my phone connecting to my WiFi.
Also if you use MAC Address Filtering on the modem/router, you should disable/clear that and let phone re-connect before enabling mac filtering again.

The problem I am having is not that it won't connect to a particular network. Wifi will not initialize on the device at all and is stuck in "Turning On..." state. I found more and more posts where people ended up having to send in to Samsung so I spoke with them and even though I purchased the phone used its thankfully still under warranty and they will be replacing it. The did not confirm whether or not it was a true known device issue but were quick to file the exchange for me.

sigh, me too!
Just started having this problem on 4.3.1
great.

In my case, I had to wipe system and data before reinstalling my ROM.
Though the only reason it was happening to me was because Beanstalk 4.4.2 didn't want to get past the splash screen when I tried to install it so I downgraded back to ICS 4.0.4 without wiping. Good luck getting this issue fixed. Also another kernel might fix thingz for you if your current one does not like your device.

I have a similar problem. After a while, WiFi gets disconnected. If I go in settings - wifi, i get the message "unfortunately, settings has stopped" and I can't get WiFi to work again until I reboot the phone. The Wifi works again for a couple of minutes then stops.
I have flashed various different ROM (CM11, PA) but keeps getting the exact same behavior.
I've rebooted in safe mode and I don't get the problem now.

[Q] Unable to connect to secured wifi networks.

Hello!
This began about a month ago. I was using Lollipop 5.0 and had absolutely no problems with my phone until one day, all of a sudden I wasn't able to connect to my home wifi network. I enter the password and it just says saved,secured. Then I discovered I was unable to connect to any secured wifi network. I tried soft and hard restarting my phone, restarting my router, forgetting my home network and trying to reconnect, I tried clearing my Google services frame work data, and still nothing.
I finally decided to downgrade to Kit Kat and did a factory reset and loaded a stock version; no dice, I still was not able to connect to secured wifi networks. I tried rooting my device and deleting wpa_supplicants.conf, still back to square one.
I find that I am able to connect to unsecured wifi networks.
Im at my wits end, I really do not know what to do. Please help.

Suddenly device can't access internet

I'm running the latest beta rom, and since yesterday my device can't connect to internet no matter if i'm connected to a wireless router (i have tried 3 different routers in different places, home, work, friend's home) or using my data plan. Last thing I was doing was sending and receiving messages. After that I went to sleep and when I woke up device had no internet access even though I could see the Wi-Fi symbol or/and the 4G symbol from my carrier.
I have rebooted the device, switched it off, enabled airplane mode, wiped cache from within recovery. I even dirty flashed latest beta zip on top of the rom i'm already running, but nothing helped.
Any suggestion on what to do?
If it's possible I don't want to wipe everything and set the device up all over the beginning. The device isn't rooted and I don't have Titanium backup installed in order to restore the device in few minutes.

Wipe system, reflash the rom. You don't lose anything it just overwrites the system partition and pray it works. Otherwise you are going to need to do a full clean install. Keep in mind it's Open Beta, stability issue might be there more often.

All very fine in my Op5t with 8.1 5.1.1

Do you have battery saving apps installed and are you running stock? I've got the same issue here. Deep sleep breaks wifi. When I turn the screen on (exiting deep sleep), I either need to wait long for it to connect, or sometimes just have to reboot to get it to connect at all. I've contacted support but I think this may take some time...

Same problem here. I reflashed 5.0.4 after a factory reset. It still happens. The ONLY thing that changed is I keep getting notified to update my os. There's a check box to automatically download over WiFi. Could this have screwed something up?
I've started having other strange problems like Chrome getting very laggy periodically, and have had to reboot more these past two weeks because of connectivity issues than I have in the entire time I've owned the phone.
My next step is to do a complete wipe off everything and start completely over, but I'm doubtful this will help.

This is the issue! If you switch the setting to "always on", there is no problem. So yeah I am having the same problem, very annoying. "wifi only on when plugged in" is broken, and then wifi settings keep crashing!

i also have this problem sometimes

I upgraded to 5.1.1 after a wipe off everything (data, cache, system, sdcard, every check box available on TWRP) and it still has a problem.
Any suggestions on how to debug this?
