[Q] Firmware, Custom ROM Required for Xtab A10 3g Model

Hi I Recently Bought Xtab A10 3g model with inbuilt Sim from NXG Electronics.
The Sim Connectivity is very bad and am not able to connect to the Internet Properly. It is disconnecting automatically after one hour of use. The Network goes of then and when i tried searching for networks there is no response.
Kindly provide a solution for solving this problem.
Secondly the Apps are crashing very often. Even though the Table is powered with 1 GB Ram apps not opening smoothly.
Experts here can help me solving this problem through an update.
Thanks
Vivek

I have got Xtab 2G. I'm searching a custom ROM for it. Haven't checked out the phone connectivity yet, but I get problems with the wi-fi connection.

Wifi bug - connects to network, but not internet

I'm experiencing a bug on my Nexus 5, when I first unboxed my device and setup this problem arise for the first time, problem is Nex 5 is connected to my home wifi network but no internet connection/data transmission !! at that time I tinkered a little bit like forget network and reconnected it then it was fixed, after that this problem rarely appear. Then comes the real problem yesterday I rooted my phone then it wont connect to internet same as before connection is accepted and have full strength signal but not connecting to internet, I've tried rebooting, forgetting and connecting, troubleshooted PC etc but nothing seems to fix the problem !! I double checked my network like I connected my tab with wifi and it's working perfectly fine.
Is this a common/known bug with Nexus 5 ? Or it's just me ? (h/w issue)
Any known fix other than I mentioned ?
Does rooting caused this problem appear more frequently ?
Any response will be highly appreciated.
Thank you

Try connecting to a different network, it may be a compatibility issue. Also try rebooting your router/wireless. If that doesn't work then try restoring factory image.
If none of those options fix it then there could be a problem with your Nexus 5's hardware

I'm now flashing factory images, if that doesn't work I'll do a replacement.

I have this issue too, with different WiFi routers.
(Full stock Nexus 5)

Out of intetrest what countries are you connecting in. When I had a Desire HD I had trouble connecting to Turkish routers. Different frequencies? Have you ever connected to your router with an actual connection?

Have yu tried disabling wifi optimzation?

I did tried with each and every option toggled with but still no way.
Sometimes out of nothing it gets ok then goes bad again.
I'm from India and using Teracom router. Funny thing is my tab here working just fine with my home wifi network, I'll try with another wifi network tomorrow.

Merely rooting the device would have no effect on the Wifi connection. Did you also install a custom rom or kernel?

Yeah, so it's a wifi thing. Did you try changing the channel on the router? You can use inSSider to find the best one.

I am having the exact same issue. started today around noon. i performed a phone reset and the problem persists. i would love if someone could help us out!

Hey guys I'm having the same issue. I was on lollipop, flashed Kitkat factory image, same problem. Have deleted, wiped, etc everything I can do. Tried safe mode. Nothing works. Started around 10AM today. It was working fine before.

I'm having the same issue. Has anyone found a fix?

has anyone found a remedy for this?

Exact same problem!!
Any answers wud be much appreciated

There is a known problem with a zero-battery drain killing the radio - i suffered it myself. Does that match any of your experiences?

I too am experiencing this problem. My phone died the other day and when I turned it back on there was no cellular signal. I can use wifi & bluetooth fine.
edit. I was considering replacing the antenna wires, don't know if that'll even help though. How do I troubleshoot this?

All of you check this thread:
http://forum.xda-developers.com/google-nexus-5/help/nexus-5-radio-refuses-to-t2834540
If your N5 runs totally out of battery, something happens to kill the radio module. I searched everywhere for a week for a solution - there isn't one.

Terrible WiFi performance. Anybody having the same issues?

Started having this issue from a week or so. Its so terrible can't even stream a single YouTube video without network connection issues. I have a xiaomi mi3 connected to the same network and it can perform without any issues. First screenshot is from xiaomi mi3 and the second from opo. Does anyone have the same issue with their opo. Please let me know if their is a way to fix this. Opo is running stock cm 11s version xnph44s.

Maybe you have apps that slow down your WiFi Connection. Are you rooted or have you made any changes on your system? A Factory Reset should fix the problem.

Thanks for the reply. I am running stock cm 11s. Didn't root or not running any mods. Its bare stock. I couldn't even have a good network connection for at least 5 mins straight. Play store downloads take forever. Thanks appreciate the help.

Yes, me too.
Worse connection "power" compared to my old Galaxy s2 and sometimes I have random disconnection...

And failed to mention that there is no problem at all with lte mobile network connection. My OPO stays connected to the WiFi network and signal strength is strong but can't get packets.

[Q] Connection drops going from Wifi to 3G

Hi, does anyone else have this problem on the latest firmware?
When I'm leaving the house after being connected to Wifi, my phone won't connect to 3G. I have to turn the data connection on & off to get it working.
If I'm going from Wifi to 4G or 4G to 3G it works fine.
I'm running 23.1.A.1.28 UK stock firmware, but the same thing happens on Moonbreakers 2.5. It's not my phone as I've tried 2 different ones and the same thing happens...
Cheers

You can try diferent baseband

im running german version 23.2.A.1.62 and don't see this issue, when I leave a wifi area it automatically puts the data connection on
