[Q] NO DATA CONNECTION on MIUI for T-Mobile G2x HELP!! - Android Q&A, Help & Troubleshooting

Hello, I recently installed the MIUI port for the T-Mobile G2x (here at http://forum.xda-developers.com/showthread.php?t=1421713) and I really do enjoy it, but about 80% of the time, my data connection isn't working. The icon doesn't show up in the status bar and it just doesn't work. It usually works at first, but once I turn WiFi on for the 1st time, use it, then turn it off, data quits working. Occasionally, I can get it to work after rebooting several times, but I'd like it to work normally. I've reflashed the ROM, rebooted, toggled Airplane Mode, and so on, but nothing gives. How can I fix this problem?? Thank you for answering.

Wifi error after OTA update

Rooted the phone then applied the OTA update and since then i keep getting a wifi error. Im currently out of the country so can't connect to sprint. Any ideas?
Anyone?

Yup, had this problem after applying this OTA.
When I click the checkbox to enable wifi, it just shows "error" and does not enable wifi.
A factory reset fixed it for me.
My wifi turns on and connect but won't give me any data

The Atrix has a driver related issue that causes problems connecting to WiFi access points in certain countries. I'm pretty sure they have figured out a workaround over in the Atrix XDA section, sorry I don't have a link for you.
Hi,
My name is Fisher, I have the same problem, I have the phone in Australia and I updated over wifi then my wifi just says error underneath it, also 4G does not work. I can turn wifi on by first putting the phone into aeroplane mode then restarting and turning wifi on while still in aeroplane mode. I have managed to get all working occasionally by having aeroplane mode and wifi on, then going to system updates which are greyed out then turning off aeroplane mode by holding down the power button and when ive done that i have a second or so before the wifi dies to click motorola software update that is now not greyed and it sometimes kicks everything on;-)
I have tried factory resetting the phone 3 times and formatting internal sd on third time, did nothing.
Now i have some dmesg logs with the wifi under error, working in aeroplane mode and all working with my trick, so let me knowif u want them all.
I have a feeling the issue could be a sprint app or process that disables it, look at the access/security settings for sprint zone, it can control wifi, everything seems to be briefley activated when i start the phone in the notification bar then wifi and 4g die, so maybe a sprint process detects that the phone has not activated or something and kills wifi and 4g.
I have reported this on the motorola forum in the thread someone else started, look for " motorola photon wifi error" in google and it might be the first hit.

Sounds good. Ill give that a shot. Lemme know if you find out more
Mine is working fine, though today I turn WIFI off and my battery had a run away effect. The battery drained 30% in 10 min and the phone was at 116 degrees. It also rebooted itself twice but now it is fine and I turned wifi on and off a few times and no ill effect.
and yep I have the update.
Wifi ERROR after OTA update
hello everyone
i am not a US resident and i bought this amazing phone i am using Cellcom Israel Sim card
i just saw the firmware update,the update run smooth but after the reboot i try'd to turn Wifi on
and getting an ERROR.
try'd to reboot the phone - wifi not working
try'd to pull out the battery and restart - wifi not working
the only thing that works is when i restart the phone in AIRPLANE MODE the wifi works
but soon as i turn the AIRPLANE MODE off the wifi disconnected and cannot turn
it on again until turn back the AIRPLANE MODE again.
i do not using any data plan connection i dont have any...
what can i do??
Just do a factory reset. That will solve this problem.
Its a known problem. Lot of people are facing it after applying OTA. Just do factory reset and you should be fine.

Factory reset doesnt do a thing bro
Hi, I had the same issue actually watch the router and say the wifi connect and then drop, i installed wifi manager and then for some reason it started working and i haven't had a issue since.
no sure why it did this but i also restarted the phone multiple times trying to get it syncing and it wouldn't until that program was installed then after i got connected i uninstalled the app and it still connects without the app
got installed "wifi manager" and again error "error enabling wifi"
Factory resetting does nothing for me, I even formatted the internal memory as well on the third time, the only way so far I have managed to turn wifi and 4g back on and also data as data seems disabled is by:
Enable aeroplane mode, restart and then enable wifi, then go to system updates and you will see the 3 options greyed out, disable aeroplane mode by holding down the power button then click on update motorola software and most of the time that has worked for me.
kc_sheets mentioned installing wifi manager, I have installed it but not restarted my phone as I've managed to get it all temporarily working and Ill test the wifi manager when I have to restart.
Let me know if anyone else can get them all working using my method.
For troubleshooting, I know dmesg is good and probably lsmod, what other linux info can help me find out what the issue it, I would not be surprised if sprint has done something to disable wifi, 4g and data as the phone starts up, but it looks like it only disables at the last minute, does anyones wifi connect as you start the phone up, I think mine may have done.
I'm hoping we can just rename the process or app that is the issue and have a non crippled phone what we paid good money for.
Fisher
just flashed the phone and guess what??
wifi working again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! w000ttttttttttttttttt
----------------------
after reboot the wifi error starts again.
that means no luck
I'm also out of the States and I just started having wifi issues today. It would see the SSID, try to obtain IP, then fail. I just set a static IP, default gateway, etc... and that did the trick.

Posted on motorolla forum:
Hey guys, same problem - briefly:
Sprint customer - overseas for the next 6 months,
1. OTA update successful, achieved over wifi
2. phone restarted, wifi connectivity lost "error" as with fisher and the rest
3. airplane mode allows wifi connection until GSM is connected again, at which point it gets knocked off
4. I /also/ fat fingered my phone during one of the restarts and had both wifi and GSM working, but it's my nature to test things, so i restarted and of course now it's gone.
5. I am not able to attempt wally's re-register with Sprint approach as I will be away from the states untill January
6. I tried the update sprint zone fix - no luck
7. I tried the disable roaming guards - same as fisher, some of them are green and grayed out, no luck
Thank you !

[Q] Problem with Simvalley SP-140

Hi
I need help with my Simvalley Sp-140, my wifi is not working. It turns on sometimes, and sometimes not. Also when i press to turn on wifi from on it goes to off. I gave factory reset but it's still not working.
I tried a lot wifi apps but with no resault.
There is no update for my phone.
Or if there is compatible rom i'll like to try it.
Android phone without wifi, useless.

[Q] WiFi Hardware Failure, need help.

Hey guys, So here's the problems. I believe my WiFi/Bluetooth hardware in the phone took a crap. I was running stock (rooted) and the wifi was starting to give me problems like tethering would not always be visible and whatnot then it just stopped working completely.
I installed CM10.1.2 along with flashing the boot.img (phone is S-On) and no help, the support thread there told me to try a sense rom and if that didn't work its most likely hardware failure... so I did (EclipticRez v8) along with installing their kernels blah blah blah same problem.
So here's what happens. The WiFi will stick on the "Turning on WiFi" so it seems like it just keeps attempting to turn it on. Occasionally it will just say error. When it is stuck on the Turning on WiFi it absolutely kills my battery. 10% an hour with the screen off in Airplane mode. When it says error my battery life is fine, but when I open any app that uses data wifi tries to turn itself on. I have tried the settings to "Never auto turn on WiFi" and it doesnt help (I think wifi needs to be off completely for that setting to help, but I cant get it to any other state but error or turning on wifi.
So obviously this is not fun at all for me or my battery. Now where I need help is if there is a way to just completely remove wifi from android. Like is there a way to just get rid of the kernel driver for wifi so It doesnt even exist on my phone?
Any other suggestions would be greatly appreciated
So if Wifi and BT don't work. Hardware then. Seems like it's starting to happen more frequently nowadays.
Same thing started happening on my wife's Rez last week. Mine is still running fine. I wiped and installed 3 different roms to establish that it is hardware related. She still isn't convinced it isn't due to me flashing new kernels, etc.

Wifi being stuck on or on/off troubleshooting

So I know this topic has a few posts many a year or so old but I'm looking for a possible work around for this issue. Here's a background of what happened:
I have a rooted note 4 originally running cm12, I wanted to return to a stock build and when I did something happened (can't remember what) and my wifi stopped working it would click on them immediately off my first thought was kernel so I flashed a new one but didn't help I tried a different stock build 5.0.1 instead of 5.1.1 but still same issue. I went back to the cm12 and that seemed to work fine still, I looked for another stock build because I'm stubborn and flashed a different kernel than the previous ones I've tried. This seemed to fix my wifi issue at least for a day then back to the same issues. Anyway here's what I've been messing with to try and figure this out.
I'm focused around the file wpa_supplicant.conf as I've tried restarts and all that but that won't do anything. What I have noticed recently is when I don't have any networks saved in that file I can toggle airplane mode and try toggling wifi, after a few sometimes dozen attempts it comes on and works fine so long as it stays on. If I turn it off I have to restart my process of going into wpa_supplicant.conf>deleting my saved network>toggling airplane>then spamming wifi. As I'm able to repeat this it leads me to believe it's not hardware related, slim chance on loose cable, But if there's a way to prevent the system from auto saving a password that might help with a workaround. I've tried changing that files permissions as well as the ones in the system>etc>wifi folder but they get changed back
Anyway I'm still working on finding the root cause but will update if I find anything also tried deleting the wpa file and that works to after a restart but issue comes back and so does file which doesn't seem to me that its a corruption issue
Update:
So I somehow crashed my Samsung messenger app switch to hangouts and then back so decided to wipe my phone and refresh the OS. I factory reset then advanced wiped cache, dalvik, system and data. When it rebooted I tested the WiFi in the system setup and it worked fine I could turn it on and then off normally so I decided to continue setup once fully setup and no other apps installed I retested the WiFi. It worked fine I connected to an access point and it stayed connected I then forgot the network cycled wifi and tried again and again still worked so I let it sit and would test it throughout the day. About an hour or so later the problem reappeared which was odd. I did my old workaround deleting wpa_supplicant.conf and toggling wifi until it turns on. I got it to turn on and connect to my home WiFi and left it, so far I've kept my wifi on and it's stayed active for 24hours now and reconnects fine to my home router when I'm in range and back to lte when I'm away so right now it seems I can have wifi if I don't toggle it off. Still not sure what's causing this issue as since I'm currently using wifi to write this I don't see it as a hardware issue. After trying multiple kernels I don't see that as the cause either, although possible. Will keep messing around and update if I find anything further
Update 2: so far I've been able to keep my wifi working great as long as I keep it on and don't toggle it off. Doing this has kept it active and auto connecting to my home wifi for a week straight. I make sure to keep wifi I during sleep so it won't disconnect but it also seems to stay active through restarts which is great. This still leads me to believe it's software related and not hardware but not sure where the issue is.
Update 3:
So far I've just kept my wifi on while trying to find the issue. The only other issue I've come across was since my wifi is on 24/7 and auto connects if I want to use my lte instead i have to either turn off wifi or forget my home network which neither is an option. But I have found a solution:
I was able to add a shortcut to my home screen that actually disables the current wifi connection without disabling wifi and forgetting the password. To do this you must have Tasker just create a new task in second tab, I named mine disconnect wifi, click the plus sign and select "net", next select "wifi net" there is an option that says disconnect. Have that selected then go back and thats it,add in icon on bottom right to use as a shortcut. I've tested this and it works great one tap and it disconnects the wifi but keeps wifi turned on and if I want to re connect just go into WiFi settings and choose the one to connect to

I need help

Ok so to start off im gonna give you some information: my phone was rooted with magisk and it was running b360, it worked just fine until one day my wifi kept turning it's self off for no reason.That kept happening but not very often so i didn't mind it. Today my wifi wouldn't start at all(the switch thingy went blue then gray immediately) again and if i tried to turn it on again my phone would reboot.I then unrooted and went into safe mode to see if it would fix the issue but it was the same, so i tried recovering my data from twrp. That didn't fix anything once again, so i did a factory reset(that prolly screwed me over big time) after the factory reset i realized that my phone wouldn't finish the setup thing because it needs to connect to the internet to check for new updates. So my issues are that i can't seem to be able to access my phone through adb since when i use "adb devices" it doesn't show my device, and that my phone is basically unusable right now since it wont get past the "checking for updates" phase. So what should i do? Any help is appreciated!
*update*
I got past the "checking for updates" phase and i completed the setup by sheer luck(my wifi worked for a couple of seconds), but the problem still persists. My wifi can't be turned on, or when it turns on it stays like that only for a couple of seconds and then goes off again also my phone crashes from time to time aswell(usually when i mess with the wifi, but sometimes it just does it on it's own).
I know is abvious, but is WiFi+ turned on? That can turn off your WiFi for you if not near a saved hotspot. Could be a confusion between this and location services.

WiFi+ is turned off. From what I've observed so far after i restart the phone i can use the WiFi for about an hour or two, after that it stops turning on. But if i use it for about 20-30 mins, turn it off, and turn it on again after a while when i want to use it again, it works (obv if i use it for 1-2 hours the problem will occur again). So what I've been doing so far is just use it for about half an hour then turn it off until i need it, and repeat. I know that im probably not making much sense right now but i don't know what to do anymore.
