Wifi Tether Connection Problems With Thunderbolt

**priapos#ac** · 09-14-2011, 07:50 PM

Greetings,

I have a rooted Htc Thunderbolt running Cyanogen.

I also have a Galaxy Tab 10.1 that I cannot connect to the wireless tether program or Barnacle wifi.

It sees the SSID from wireless tether but is stuck "obtaining IP address."

In Barnacle it doesn't even see the network created.

My Ipad connects to the wifi tether feature of either program without significant trouble.

Any thoughts on how to remedy this problem?

Thanks in advance.

There's a fix on XDA to get ad-hoc tethering to be identified by the Tab. I would assume that this is the issue with Barnacle not picking up the wifi. I'm not sure what the problem is with it being hung obtaining an ip.

Here is the XDA thread :

It worked on my wifi tab with TW. Backup if you plan on doing it.

Here is a post in the above thread that breaks it down if you'll be using Root Explorer (or Es Explorer) to do the mod:

Again, make sure to backup via a Nandroid or rename the original file wpa_supplicant_bak then copy the downloaded replacement into the /system/bin. This will allow you to delete the new wpa_supplicant file in the future and remove the "_bak" portion on the original and have it restored. Or, you can just restore the backup you made before doing the mod.

It should work if you use WPA2 as the encryption method... Doesn't seem to work with just WPA, same symptoms as you describe. I switched and it works fine...

Can you describe how to do this.. I don't see any such settings in barnacle or wifi tether. Thanks

In the wifi hot spot settings use WPA2 (AES) found in the security section. My Thunderbolt works fine with this setting. I can't use it using simple WPA security, won't aquire an ip address...

Update to this thread for anyone have the same problem.

The suggestions in this thread did not help me unfortunately. I didn't even understand some of them.

Fortunately if you have a rooted phone with cyanogen, portable wifi hotspot is included. It is buried in the wifi settings, and the galaxy tab has no trouble connecting via this option.

Barnacle and Wifi tether were both terrible and couldn't establish a connection with my tab. They are not even consistent options for connecting other devices, frequently crashing.

The built in wifi hotspot on cyanogen is fantastic in my opinion and just plain works. No need to root your tab at all if your phone is rooted with cyanogen.

I finally got it working on my rooted Thunderbolt (running latest HTC GB release).

Download the latest wifi tether: .

I changed two settings: Setup-Method:"Softap (master)" and check "Routing Fix."

After that, I was able to connect my non-rooted Tab 10.1 to my Thunderbolt.
