Sucessful Apple TV OS 4.2.1 Tethered Jailbreak With Problems

 So I've successfully jailbroken my AppleTV using these instructions

 

http://www.appletvhacks.net/2010/12/16/how-to-jailbreak-apple-tv-2g-on-ios-4-2-1-with-pwnagetool/#more-860

Of note I had to use iReb from ih8sn0w to install the package I built with pwnage through iTunes with no errors.i

 

UNFORTUNATELY I can get neither wifi nor ethernet usage rendering the device essentially useless.  I was wondering if anyone had had some success with this matter. 

 

Additionally I gave this a shot 

http://www.mobilefiledownload.com/downgrade-with-no-shsh-no-host-files-edit-4-0-2-4-01/

where you put an old 4.1 build into a 4.2.1 package and as long as I used iRed and the tiny-umbrella server on my own computer instead of the itunes authentication sever it makes it almost all the way through until I get a 1600 error at almost the end of the process.

 

 

ANYONE WITH ANY INSIGHT ON EITHER DEVELOPMENT I'D LOVE TO HEAR IT. THANK YOU.

Sorry for the double post but if anyone can recommend another forum to post these questions in I'd appreciate that too.

This tutorial did it for me: http://www.youtube.com/watch?v=4EWKr7Ww_c0
