Chinese android tablet wifi problem

**abuck01** · 03-05-2013, 05:14 AM

Hi to all

I have acquired a 7" chinese tablet from a friend who gave up with it because the wifi will not turn on, as soon as you turn it on it turns back off. I was wondering if flashing it with new firmware might fix it because several factory resets have failed to fix the issue. Having done a bit of digging around it would appear that this is a minefield for the uneducated such as myself. The make and model is unknown, there is no text or name of any kind on it but the info in the "about phone" section states the following:

Model number - SoftwinerEvb
Android version- 4.0.4
Baseband version- 1.5
Kernal version - 3.0.8+android3@Linux#80 Wed Nov 7 15:50:34 CST 2012
Build number - nuclear_evb-eng 4.0.4 IMM76D 20121108

any help here would be great else I fear it may have to be filed under "B"

I am sitting with a similar problem with the same type of Tablet.

The tab picks up the wi-fi and connects to it, but then error message comes up "Authentication Problem".
Bit annoying that one cannot get these thongs to work, but then I suppose this is what happens when people want to buy cheap and not original.

Hi,

I don't know if the region where you buy your devices means that you end up with a different piece of hardware but I have this similar WIFI problem only after I've updated to 4.1.2 and above.

I have a NOTE 2 LTE bought in HongKong. I used it in China and I had no problem at all until I updated to 4.1.2 last week. And I have a hell of a problem to connect to WIFI. Sometimes I have to forget the network, reconnect and reenter the pwd for it to work. Sometimes, I have to reboot the phone.

I have the same problem on my Galaxy Tab 10.1 when I installed the latest Cyanogenmod build, 4.2.2.

So my guess is that it is software related! The updates killed the WIFI. The behavior is so erratic (works now, doesn't work in 30 minutes...). It's very annoying.

If someone knows the reason and has a solution, please share.

The tablet I have does not do what you describe, when I try to switch the wifi on, it just turns straight back off again although the display indicates that it is actually 'turning on wi fi'. I suspect that re flashing with a different ROM might fix it, but its finding the right one. The device is already rooted and everything is in place to do a ROM update, I just need the right ROM.

Ok, so I did a bit of digging around and it turns out there is a conflict with the wireless driver failing to load when requested, I would really like to flash a new rom to the device but not sure how to go about it. I do know that Clockworkmod will not yet work with my model which is SoftwinerEvb on a A10 processor so don't know what else there is to use. I need to backup my current rom before I do anything else but have not had any success there either. I have downloaded QtADB for windows which allows me to connect to my device but that's it, attempts to backup my rom with it have proved fruitless. Can anyone recommend a utility which will allow me to back up my rom ?
