[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.

Wi-fi should work the same, if anything you should have data or network problems.
Try booting into recovery (Volume Up + Home + Power, hold together). It doesn't require root, you will be in Samsung's stock recovery.
Clear only Cache then reboot your phone. This will not clear your data or apps, this will simply delete their temporary files and force them to re-configure themselves to adjust to your current phone's state.
Maybe try connecting to a different wi-fi connection?

you've to flash it 2 times for that it works well, and in between the flashes you've to do a factory reset and cache wipe...
also make sure that in odin f reset time and auto reboot is ticked

[Q] SlimKat 4.4.4 and WiFi Reconnect issue

First, I've had this issue since Build 6.8. I was hoping a Clean Install using Philz Touch Recovery v6.48.4, which is the latest, and selected Wipe Data and select Clean to install new ROM which Formats /data, /cache, /system. I also wiped Dalvik.
Once completed I did the following:
Clean Install of Slim-d2lte-4.4.4.build.7.0-OFFICIAL-5979
I then installed
Slim_full_gapps.BETA.4.4.4.build.7.x-190
Rebooted and waited for SlimKat to boot-up. WiFi/Data both full scale. Everything Restored just fine and things are running smooth.
Then after running a few errands outside of WiFi Range, I returned home within WiFi range only to find out that WiFi had not reconnected. It tells a WiFi connection is available but will not reconnect to it. So I go into Setting and select WiFi and tried to manually reconnect. It says connecting and then goes back to Saved Connection without connecting. This same thing on other WiFi connections such as McDonald's or other open WiFi Connections.
I then do a re-boot and everything is back to normal. WiFi connects without issue and again things are fine and running smooth.
Every time I leave WiFi range and then return within WiFi range, the problem re-occurs. A Re-Boot and everything back to normal.
One thing I've always noticed when doing a Clean Install as stated above, all of my previously stored WiFi connection are still there. Same on Ringtone/Notification Tones.
With the problem I'm having, could it be something that is not being wiped/cleared out during the Clean Install process. Or wondering if it could be somehow that the WiFi Radio has gotten corrupted.
I have also tried different Kernels but again the result is the same.
Hope this is not too much of a noob question and I have searched about everything I can think of. Wondering if anyone has had this problem or have any ideas of what could cause the problem.
I really hope I can get this figured out. Thanks

If you don't have to manually reconnect and enter your password, then its not being wiped. (Or you are restoring it from a backup.) Have you tested it after the clean flash, but before restoring anything? What are you restoring and how?
It sounds like a Rom issue otherwise and you should probably ask in the rom thread.

First I don't know what I've missed wiping. When I say restoring, I'm referring to letting Google re-downloading everything from the Play Store.
I know the WiFi radio are in a different location but like you, when I do a Clean Install by formatting /data /cache /system and wiping dalvik, I wasn't expecting all the stored WiFi connections to still be there, but they are.

Its possible its being restored by Google's backup, but I don't use it myself so I'm not certain about that. Its also possible the rom may save the config file elsewhere. Again though, I don't use cm/aosp based roms so I'm not too familiar with any of their specifics.
Next time you try a clean flash, do not sign into google during setup. Instead go straight to testing wifi to see if it still remembers the connections. Do you have it set to auto connect to any open networks? If so you might want to turn that off.
Have you searched or asked in the roms thread yet? It might be a known issue or something a few others have encountered and know how to fix.

Ya I don't sign into Google at the initial start up after the flash because my WiFi is no able to connect. I will double check the auto connect feature. But I having this issue with other 4.4.4 ROMs also because I tired however on those ones I am amvle to toggle WiFi on but in advanced it has the region set to Europe and when I switch it to Canada it doesn't want to save the change

"LTE !"

Hey all, hope you are having a good weekend.
the problem that I am having is that my phone is showing that it's detecting LTE data, but nothing will load with it because most of the time the icon indicates "LTE !" This problem started about a week ago and I'm unsure if this is a carrier data network issue or something to do with my phone. I am running cm13 and here are a few of the things I have tried:
-factory reset data
-restore to backup of a time when my phone worked properly
-advanced wipe data, system, cache, etc. everything except internal and external storage
-do the previous but install the latest version of cm available with gapps
none of these attempts successful. anyone dealt with this before? any input appreciated

There is an option somewhere in settings to enable only LTE or 4g. Did you set it to 4g/LTE only to see what happens ?

Yeah it was already set to Lte only. I also tried switching it to 3g and then back to Lte only to see if that would make a difference. another thing i tried was taking out the sim card and re inserting it

Okay so if it's not the network ...then it could be the modem image itself. Did you come from stock or an another custom ROM to cm 13 ?.

Just turn on and of AirPlane Mode. Then it'll work fine. Just a DNS bug or something. Not really a bug deal.
