[Q] Nexus 7 3G (Wifi problem) - Nexus 7 Q&A, Help & Troubleshooting

Hello xda
I use a Nexus 7 2012 3G edition. Last year when I first inserted my SIM the wifi stopped working, it's suck on the message "Scanning for wifi networks" although every other device connects with string signal, after looking through these awesome forums I found that the problem is with country wifi code (I live in Sudan) and WiFix Manager app solution worked for me (I just need to make sure wifi is off whenever I restart for it to work).
This is the WiFix manager thread: http://forum.xda-developers.com/showthread.php?t=1445766
Kudos to the developer
My nexus 7 is rooted and the WiFix worked from stock rooted android 4.2.2 up to 4.3
Now when I side loaded Kitkat (4.4) WiFix manager would not work and the message "Unfortunately WiFix Manager has stopped" appeared.
The wifi would not work unless I take out the SIM card and do a factory reset, and when I reinsert the SIM card the wifi stops again. I had to restore my android to 4.3 for it to work again.
Things I tried to no avail:
1. WiFix manager
2. Wifi Codes app (http://forum.xda-developers.com/showthread.php?t=1982149) to change wifi country code.
3. Market unlocker and choosing AT&T carrier
4. Script and sqlite3 (http://forum.xda-developers.com/showthread.php?t=1436683)
So I was wandering if anyone has encountered this issue and have a workaround solution
Thanks in advance

Play store problem. plz help.

Hey guys!!
I really need your help. Is My IP blocked by google? Playstore works fine on GPRS but when I try to download applications through Wifi on galaxy note it shows server error. When i click download, it say country not supported. It lets me download through GPRS. Can anyone pls help? 'this item can not be installed in your device's country'
Regards,
Abhi
It was working fine uptil now. I have been downloading applications since 6 months. Every time I try to login it gives me server error but it works fine through GPRS. One more thing, I can download all the apps which I had downloaded previously from my apps without any problem. I don't want to use market unable to resolve this. Can you please help?
search online for the app "market unlocker" or something like that,
makes you go to the market through proxies in different countries.
Market unabler, right? I don't want to use that. It's not a country problem I am sure because no one else from India is having such issue.
you may try and fix permission on bootloader. i had your same problem with a custom rom, i fixed permission and now it is ok. let me know how it goes
@PazzoPazzini
Ah! not using custom rom. I have not rooted the note yet. Just bought it before 2 days. My bro is facing same issue on same wifi. He has galaxy ace.
wifi goole play server error
me too hvng the same problem
Since when you are facing this problem? I am having this problem since one week.
No one seems to have solution for this. I found an alternative which might help few ppl. You have to turn on the GPRS first and click on download (any app you want to download from play store.). Once download animation starts, you can turn wifi on. Strangely, it allows to download through wifi then. Otherwise, I get an error that this item can not be installed in your country. I am not sure how long thing alternative will work.
I am having same same problem since yesterday. Error 921 or 941. I don't get it, because when I try download something on my S2 it does it without problems. But my Note doesn't download at wi-fi or over network data connection. Tried remove battery, restart the phone, nothing. Running everything stock, DBT latest firmware, unlocked phone on AT&T network with unlimited data.
My problem is solved now ... Remove all account information from account and sync by doing hard reset. Created another gmail account with US address. After that, unchecked the background data button and unabled it after some time. It started working without any problems

[Q] wifi not working after inserting SIM card

Hi,

Did you restore from settings, or reflash with fastboot? If from settings, then download the image and flash from fastboot fresh.

[Q] Phone cannot connect to Mobile Network (CM 10.2)

Hello, I had successfully flashed my LG G2 (D802) from stock to CM 10.2. The sim card was recognised and joined immediately to EE (UK - Mobile Network *T-Mobile/Orange*). During Christmas I tried flashing a new nightly from Cyanogen Mod (11), however I had an outdated clockworkmod version (even though I couldn't update it further). I couldn't launch back to CM 10.2, as the data was wiped when trying to flash CM 11 (Nightly).
Due to not having a back up file, I reverted to factory settings first, then wipe 'all' data off my phone using ALL the options avaliable on CWM. I then had to use 'adb' to push CM 10.2 back into to the phone. It successfully flashed and it was running stably. During the set up pages, CM gave me a pop up to look at sim card instructions to 'get it working', i thought this was a minor problem and couldn't to set it up. When this was finished, gave me everything (WI-FI, bluetooth etc.), however I didn't connect to my Mobile Network 'EE'.
I set 'Data Enabled', Network Mode: WCDMA Preferred.
I tried automatically/manually connecting via the CM settings, but response was 'Could not connect to this network. Please try again later.'
So no luck so far in connecting the phone function back up.
I would be truly thankful if everyone could help with a solution. ^_^
Many Thanks!
I've found out that the phone is locked to a HK network, but I am currently studying in the UK. The problem is that I can't unlock the phone in the UK with using the HK network; I have a HK sim card as well as UK, but since the phone is locked I can't use a UK sim card and the HK sim card doesn't seems to register UK Networks.
Anyone got suggestions to bypass this?

[Q] Problem with network after flashin SlimKat and Cyanogenmod

Hello.
I have a problem with my LG Optimus L5 E610.
First I flashed SlimKat ROM (I had stock 4.1 before that so I had v20 baseband). At that point I had network but not WiFi.
I din't like that so I flashed CyanogenMod 10 (without previously flashing v10 baseband required for it) and I had WiFi but not network.
I tried flashing v10 baseband but the network problem persisted.
My IMEI is still in my phone, i get it when I click *#06# so that's not the problem.
Then I tried flashing v20 baseband and install SlimKat again - same problem (no WiFi and no service - WiFi never seemed to work on SlimKat but last time I installed it it had service)
Then I flashed v20 again and installed CyanogenMod 11 on the phone. As of now everything is working except the network.
Apps are running normally, WiFi is working, Bluetooth is working.
I tried: Toggling Airplane mode, rebooting, toggling GPS, Bluetooth, toggling 2G data only.
I simply do not know how to fix this and after a few days of googling without answer I came here to see if anyone can help me.
The main problem is that says I don't have a SIM card in but I do (tested SIM card on other phones - it works)
I would be very grateful. Thank you in advance!

Any custom rom has wifi problems.

Hi guys,
I've got a Samsung Galaxy S4 with this custom rom.
Unfortunately, the wifi connection drops or doesn't even work at all. I downloaded another custom rom, Cyanogenmod 11. For me, this rom also has the same wifi issues. So I followed this tutorial here on XDA to update my modem and bootloader to XXUHOF2. (I also flashed the wifi fix for that bootloader in pda/ap).
The modem and bootloader update worked, according to these screenshots: (See attachments)
But the wifi connection still drops or doesn't even work at all.
Also, the mobile connection and wifi indicator have sometimes got an exclamation mark next to them. (See attachments)
When I go back to stock, the wifi works perfectly. (But I don't want stock because I hate touchwiz).
By the way the mobile data, texting and calling also works fine.
What do I need to do to get the wifi working?
Thanks in advance,
Twitmuck.
