Not reconnecting to mobile data - ONE Q&A, Help & Troubleshooting

Can someone help me ?
I come from COS12 where everything worked fine. Then i flashed COS13 (twrp) and i'm starting having trouble that when my phone lost wifi connection, mobile data (LTE/H+/E) wouldn't turn on again (had to reboot phone and then it was fine again)
Then i did a data/cach/dalvik wipe and reinstalled COS13 => same problem (went back to a nandroid of COS12 => No problem)
I then wiped again and installed resurrection rom in the hope it would be gone but NOPE no luck....... I now found that if i put the prefered network in 3G instead of 4G it works again and i can switch back to 4G.
But that can't be the meaning i think and it's pretty annoying !!
So anyone have a clue what the problem could be ?
Thnx

Click to expand...
Click to collapse
I did experience this with cursorsense rom but only when the wifi network was open, if it had encryption it would be fine.
Very annoying at the airports as they aren't encrypted haha
My phone was fine to connect wifi last few day. I dunno how it cured itself, weird enough.
But today my phone reboots again when connected to wifi network
Can someone help me out?
Is it related to cursorsense rom?

[Q] Wifi not working after rooting micromax A52!!

I recently flashed stock rom of micromax A52. There were no problems. I then also created a backup of stock rom using clockworkmod but then when I install any custom rom with root on my phone, my wifi started working incorrectly. It starts but as soon as I try to use it, wifi disconnects and shows the wifi which it out of range(although it still there). I tried to restore the backup but now with it the same problem occurs. Will I be able to restore back it? Please help me....

[Q] Xperia SP Wifi Doesn't Turn On After A Reboot After Factory Reset

I had the 'Can't Establish a reliable connection to the server' issue on my Xperia SP [C5302, Android 4.3, Build - 12.1.A.1.205, and rooted, of course]. So, I tried factory reset and it didn't work until I installed Lucky Patcher and reset the hosts file to original state. Now, Google Play works.
But there's another problem. On the first boot after reset, wifi worked fine. But ever since I rebooted it, wifi has stopped working. The wifi slider is kinda unresponsive (have a look at the screenshots I've attached).
Does anyone have any solution?
Restored using recovery. Problem solved.
Okay, after trying many different things in vain, finally restored my phone using an old backup I had. Done!
Same issue with any JB rom used with multirom as secondary rom. Searching for resolution please...

After rebooting cant get network signal..

So I was on omnirom, then I tried multirom. Multirom didnt go well for me and I noticed that when I used a nandroid omnirom backup as my secondary rom I was having these signal issues. My primary rom wasnt even working. So I uninstalled multirom, I cleaned wiped device and started over and I still have signal issues. Only way I resolve issue is to make a connection via wifi and suddenly my network shows up, I can shut wifi off and network signal stays working. If I reboot, I have no network connection again unless I do my quick fix. I did flash the latest 12.1 firmware, not sure if I'm firmware confused. Any help would be appreciated as to why this is happening.

[help] lg g2 wifi and bluetooth not working

I have an LG G2 ( d802 - International) which has some issues with wifi and Bluetooth. On my phone mac addresses(both wifi and Bluetooth) are not showing up. It happened yesterday when I was using my phone which was running cm13, all of a sudden the wifi stopped so at first I tried to turn it off and on again, which didnt seem to work because the wifi didnt turn on (I dont really need bluetooth as of my daily life). So I rebooted my phone and the problem persisted. So i decided to factory reset with TWRP ( I normally reset once every so often to speed up my phone again , and at this point my phone was getting really slow). Which I did, but then something wired happened... The upgrading android dialog box came up after the reset and it showed ~140 apps. But normally that wouldnt happen after a reset. I didnt mind that and checked to see if the wifi worked again, yet no luck. So I went for a full format of data, which also popped up with the upgrading android. So I thought maybe it was to do with the rom, and decided to try out some other rom. So i had 2 roms on my sdcard at that time, Dorimanx-V9.7-LP and the stock lg rom. At first when i tried the Dorimanx rom it didnt work and wasnt booting right so I was not bothered to fix and I went for the stock rom which worked.. and it happened again... upgrading android dialog box. So i started researching and saw it mention that this could be a cause of bootloaders not being the right version, now i do not know a lot about bootloaders so I couldnt really do anything. I tried to update twrp with auto rec ( i got the apk thru usb from pc to phone), which worked yet still no fix.
*Seen some other threads and tried the following with no success*
Deleting the contents of : /data/misc/wifi/

Details:

Running :Stock Lollipop rom for lg
