Wifi Problems for rooted users please check this.

[m3red]

Wifi problems have been solved.

UPDATE - Please read before flashing roms!!!!!!



Please check the config file for your Wifi hardware to see if its the same. Im wondering if this is the source of the problem. If its not the source Please help me find the source so all of us can work out this problem. Or the problem is the file did not fully download correctly or install fully.

Install RootExplorer.apk then goto /system/etc/wireless/RT2870STA/RT2870STA.DAT - highlight and hold until a pop comes up and then check on text edit. All check the permissions and make sure that the following has a check by it. Owner, Group and Others - Read, Write, Execute

Download the APK file here - RootExplorer 2.16
Download this file onto your your SD card by using your computer and install it onto your tablet using your tablets APKinstaller app open the app then click on install then goto the location of the file then click then file and install it.

This is my config and my wifi is working with no problems. This is copy and pasted from my tablet.

well mine does not work and i have the same stats as yours.

 

[m3red]

please post a picture of the Wifi setting page. Also try turning the wifi off then back on and you may reboot your tablet each time you change the setting. Let see if we cant fix this.

Hi M3red, The problem that you don't have the option or the ability to switch the wifi on/off. so by saying turn off then on and reboot, the only available status is wifi error for us.. We all appreciate the willingness from anyone to fix this issue, because it's really becoming a common problem. My wireless file is exactly same like yours. have you checked the wifi folder and the file under that? could it be changed to something useful?

 

[Echoes]

The error message people are getting is particularly useless in terms of diagnosing the problem. If one installs a terminal emulator, is there a way to toggle the wifi from the command line to get something a little more useful?

Hi,

I'm new at this. I have looked at other source and tried the following command in the Terminal

$svc wifi enable
[1] killed svc wifi enable.

Then tried

$ifconfig tiwlan0
tiwlan0: no such device

Here is the output of the #dmesg after a clean boot.

I only see Wifi Launch and then timeout after 10s.

Thanks for the help on this.

 

[vdubbus77]

#chmod 777 /system/etc/wifi/wpa_supplicant.conf
#reboot

 

[lucas_sylvie]

#chmod 777 /system/etc/wifi/wpa_supplicant.conf
#reboot

I tried it and it did not change anything

Here is a new file with dmesh

Theres a stock wifi app that you can open and close the wifi. Has anyone tried that?

Hi m3red,

I'm not able to select open or close using the wifi app it's all greyed out.
I have taken a picture of the Wireless & Network settings as well as the wifi app.


I think that Regena have a valid point on the following post. http://www.androidtablets.net/forum...-market-clean-rom-img-file-10.html#post166810

Just wanted to let you know that if you have a craig738b with 2.2.1 that z4root will root the tablet.I tried it and it works. This way you can install an uninstaller or tittanium backup and remove that little darn security guy that wouldn't let anyone install the market in the first place.
I don't know who made the roms on original post but the reason wifi is not working is more then likely the wifi module is mismatched with the kernel.

I hope this helps

Thanks

Where do we launch the terminal to try this anyway?
