I can`t enable internet in MIUI

After installing MIUI I can`t enable data transfer (2g/3g internet). Data transfer is turning on, but there is no 2g/3g logo and internet. This happens after installing all MIUI stock and custom roms. APN settings is correct, before it was ok. I`m installing via Clockwork recovery v5. Device is G2x (P999)
What should I do? How to enable it?

I believe for the g2x you should see an H next to the bars, that is if you are in a good service area.
Otherwise I think it also shows G, and E.
If it doesn't have anything at all, then I'm not sure.
Does the internet work when you go inti the browser?

I'm having the same issue....
im using rg2x right now and the only way to fix it is with a hard reboot every time i turn my phone back on

try reflashing the faux kernel it worked for me to fix a problem i had not being able to turn my wifi on it should work for you too
what i have a problem is the backupp app does nto work for me im runing rg2x miui by richie

Yah I have the same problem, I notice it works but when you use WiFi then your done w/ the wifi and shut it off the regular cell data never comes back on - You have to completely reboot the phone...I'm using SINGH-UI - same thing

Please give me a link to that rom (Richie). How to reflash faux kernel?? I should do it after installing MIUI? Or you mean MIUI Rom with faux kernel? I`ve tried lots of MIUI roms (( Same problem anyway (

I`ve tried SINGH UI too, as I remember wi-fi is on by defalut, isn`t it? So, I turned it off, and use my phone few days. Rebooted it few times, but data not worked ((

I had this problem before, go to ur APNs and go to authentication and make the authentication "None" instead of "Not set". That will enable ur data

Hey go to SETTINGS->MOBILE NETWORKS->ACCESS POINT NAMES-> in here select option button in your android phone, in the menu select NEW APN, you will get the APN settings as seen in this. In the link ACCESS NUMBER = SERVER in mobile.
As I am not allowed to post link for first ten TIMES! will guide you through
google search -> "vodafone apn address" the third result will be GPRS APN Settings with Username and Password - Modem Unlock. Click it and follow the method above mentioned.

Wifi won't work on ICS, only on HC - Help needed

Hello all I hope you can help me with this...
I'm having the strangest issue with my P6200L... Everything was working fine a couple of days ago... I was using latest CM9 by aorth here, browsing the web and everything when suddenly.... Wifi disconnected and never reconnected again...
The symptoms are:
- displays all available networks in range
- if I force to connect, all networks disappear and saved connections are "not in range"
- if I turn off/on again it displays all networks in range again, saved ones are "disabled", if I force connect it repeats the cycle.
I tried factory reset dozens of times. Didn't work.
I tried flashing CM9 again (with this and another patch I found on the thread (forgot where it is)) dozens of times. Didn't work.
I tried flashing official ICS (Open Austria) dozens of time. Didn't work.
Needless to say, I did data wipe/factory reset/format cache/clear dalvik twice between each flash.
And then I flashed stock Honeycomb. It worked. Wifi connected! All was fine!
Marvelous! Or so it seemed...
Now that I got it working again, I want to upgrade to ICS, so I flashed ICS Open Austria. Wifi stopped working.
"Ohh well", I thought, "let's try everything again"
Flashed stock Honeycomb again. Working.
Flashed CM9 + patch. Stopped working.
Flashed ICS Open Austria. Still not working.
Flashed stock Honeycomb yet again. Working.
Flashed ICS Open Austria. Not working.
Flashed stock Honeycomb. Working.
My conclusion: Wifi works only on stock 3.2.
Why? I have absolutely no idea whatsoever.
I've tried every possible combination of flashing and wiping data (except from stock ICS recovery, as I have one of those bad chips and I'm afraid of the brick bug)
Is there anything else left to try? Maybe copying some system files over from stock Honeycomb to an ICS firmware?
I'm really getting desperate here and I've run out of options. I'm hoping the community here on XDA helps me solve this mystery.
It is similiar to this bug here, but although the user there fixed it by several wipes/flashes, apparently I'm not having the same luck.

Hahahaha I'm 100% sure this is NOT the issue here
Wifi networks keep dissapearing when I try to connect. I have tried in 3 different routers with different encryption settings, so I'm sure this is not on my end.

Could be that you flash and incorrect firmware, maybe for the p6210 tab?
Sorry, I'm just guessing , I don't know what could be the problem.

No problem about that, we're all guessing
But no, I'm sure it's for the P6200 because it worked the first time I flashed. If it was for the P6210 my tab wouldn't even boot, partition layout is different...

I'm having this kind of issue aswell. Wifi is doin' fine with HC 'til flashed it to ICS. Damn, I really hope someone could help us regards with this issue. I also tried Wifi fixer, it helps but not that enough. 'Cause it connects me to my wifi but after a minute or two. It'll disconnect and reconnect. This is happening again and again. And it's kinda annoying when watching video on youtube or surfing the net. Well, just sharing my issue.

Yeah, I know how it's like... I reverted back to ICS while there isn't a fix... It's weird because it also happens on official ICS from Samsung, which it shouldn't

guys, I had the identical problem with wifi on ics. I returned to the hc and wifi worked. Then again the ics and did not work. Wipe cache, Dalvik, data, everything I tried several times and no results . Then I installed wifi fixer and it was a little better, over *# 94 349 # tablet began work with the occasional stop. a couple of times I rebooted it. and after one reboot started to work normally. I know that I m not helped, but it is my experience.

Are you talking about this app? I've tried that, but the only thing it did was to keep disabling/enabling the wifi... Several reboots later, same results... I'm glad it worked for you, but so far I'm not in luck

OK, I got some progress.... But it's still bad, keeps disconnecting... Here's what I've done...
I flashed CM9 with wifi patch and tried the app above. Restarted, no luck. Still didn't work.
I removed my SIM card, restarted in CM9, and Wifi worked! If I put it back in, wifi stops working.
I tried changing country codes with the app above, lost 3G SIM card connectivity. No wifi and no 3G, I though I f***ed up everything.
ODINed back to stock Honeycomb. Got a "no SIM card" error. But wifi worked.
Restarted several times, tried changing country codes several times, still got the "no SIM card" error.
After several attempts by removing/inserting the SIM card and restarting I got it working, finally.
Tried flashing ICS Open Austria. Both Wifi and 3G works!!! However wifi keeps disconnecting every 40 seconds or so.
Tried Wifi Fixer from Market, but all it does is monitor when wifi disconnects and then resets it. It connects again, but 40 seconds later it disconnects again, thus repeating the cycle.
It's still not usable, but it is some progress. I'm afraid to factory reset in official ICS because of brick bug, but I'm willing to do some more steps if anyone got some more ideas
THANK YOU very much for your response petrenj! We're getting somewhere here! :good:

Unfortunately I'm experiencing the same problem as yours. I have 3 tabs and all of them exhibits the problem in ICS. Wifi seems a lot more stable in honeycomb. I already tried xxlpl and xxlpn with/without wifi fix from aorths cm9. I'm also experiencing force reboots when I disable and enable wifi for sometime.

How odd... It's weird that some people have this issue while others don't... Also, I'm beggining to wonder if this is something that aorth or other dev can fix, seeing as it affects several different devices with ICS, and not only our tab. I don't think it's a hardware problem, because wifi works in Honeycomb...
So far, if we want to use wifi in our tabs we must remove the SIM card or just stick with Honeycomb... I've stopped using my tab for a while due to the constant data wipes/flashes and dedicated it to try to fix this issue... I really don't want to restore all my apps twice a day while switching between ICS and HC versions
Are there any P6210 users reading this? If yes, are you able to use wifi in your tab? As the P6210 doesn't have a slot for a SIM card, this shouldn't affect you, right?
Anyway, let's wait for aorth to be back from his trip and introduce this thread to him. He should be able to clarify something to us.

Wi-Fi Won't turn on any more

Hey guys,
I've noticed in the last few days that my Wi-Fi just doesn't work any more. It won't even allow me to turn it on. When I go to the settings, it shows the option to turn Wi-Fi on, but it is greyed out now. I don't know what happened.
I'm using CM10 nightlies. I usually flash the new one every night and that's when I noticed this start happening. Since it started, I have tried flashing back to some older ones, even doing the full factory resets and cache wipes. No luck. Even after doing a fresh wipe, when the phone starts the initial google set up, the LTE isnt even working. It takes a few minutes for LTE to finally turn on, but the Wi-Fi has yet to.
Any suggestions as to what I should do?
Thanks

I just tried this right before I read your message. I wiped and flashed CleanROM 5.0. Sure enough Wi-Fi was working, but then went back to the CM10 ROM and it appears to not be working again. I've been looking at the CM10 thread and nobody else seems to be having this problem.

[SOLVED] WIFI will no longer turn on

Hey all,
I installed several custom ROMs and WiFi would no longer turn on. In an attempt to restore it, 24 hours of disaster later I have a completely stock image on my phone. Nothing changed, and wifi still will not turn on. Everything I have attempted has not worked. It was working just fine until I installed SlimKat ROM. Any ideas on how to get working wifi again, or at least a method to test if it is now a hardware problem or software?

Wifi unable to reconnect when coming back in range

I have this rather annoying problem with my OPO: When I'm on WiFi and go out of range and get within range of another WiFi (eg leaving from home in the morning and getting on the train where there's also WiFi) my OPO will not connect.
I've tried switching WiFi off and back on, tried forgetting network and connecting again but the network just displays as "Saved". Only thing that works is a reboot. Funny thing is that it actually detects open WiFi's and displays the question mark in the notification bar.
I've read that themes can cause WiFi problems so I haven't changed that. I'm using the Apex launcher with no visual changes.
I've rooted my phone but left the bootloader locked.
Any advice?

I'm rooted with the TWRP custom recovery installed. I had the same thing happen to me. If you toggle airplane mode on/off, it will reconnect. But, as for a solution, my fix was to restore a previous TWRP backup of my phone. I also had heard that the problem could be coming from a theme. What themes have you used? I bought the Flux theme and have been using its style and fonts. I was running the stock CM11s when this happend just a few days after getting my OPO. I would try a factory reset first. If that does not work, there is a thread in the OPO forums about flashing a factory image and getting back to 100% stock.
I have switched to the CM11 nightlies as of a couple of days ago. I will probably refrain from messing around with the theme packs for now.

I'm now on KTU84P and the problem is still there
Yesterday I failed to flash MAHDI and ended up clearing everything from my phone. I had to follow this guide:
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
to get back to pre-KTU84P (can't remember the build number).
So I guess it's safe to say that my phone has had all sorts of memory cleared. And the problem is still there...

I really hate to hear that you are still having the wifi issue. One would think that if you flashed all partitions with a factory image that it would solve the problem. You might want to have a look at this thread. This guy was unsuccessful in fixing his efs and bluetooth problems until he flashed Color OS and then went back to CM.

I find flashing yet another rom (ColorOS) sounds a bit drastic. Really no way of debugging what's wrong?

Thanks for sharing. I think there are two things that can produce a major restore/fix to a phone - a nandroid restore and a major rom update. I hope it fixes yours. The nandroid restore is what saved mine.

Been there. Done that. Read the book. Got the t-shirt.
Flashed ColorOS.
Factory reset.
Booted and got through into ColorOS (skipped account setup).
Booted into recovery.
Factory reset.
Restore backup of CM11S.
No dice :'-(
What are my options now?
A couple of days ago I completely wiped my OPO - radio, modem, everything and flashed a new stock image. Nothing has helped.
I really find it hard to believe this to be a hardware issue.

Just for clarification - after flashing Color OS, did you turn on wifi and use it to see if the problem was still there while in Color OS?

If your WiFi 2.4 or 5GHZ?

Yes. I would recommend you consider doing that. If it works then I would flash a fresh Cm11s rom, not a nandroid backup. Flash the Color OS and do a full check of the Wifi.

I was having the same issue, but here's what I did and it seems to have resolved my issue.
1) Updated firmware on my ASUS AC68 router
2) Boot into recovery mode (volume down+power), wipe cache and media, then factory wipe
3) When setting up phone, did not apply CM theme on the options after logging into CM account.
It seems like WiFi might drop when you get to homescreen, just reboot phone and Wifi should reconnect. Make sure to go into your WiFi settings and remove any networks that was saved, and re-add.
Still not ideal (since it seems like themes might be killing WiFi for some users), so hopefully a new OTA update will solve this problem.
