after jailbreak

hi and thankyou to all that made jailbreaking possible.i have saved shsh from appletv that was already jailbroken.i have restored and all went well.only problem im having is when i plug any kind of internet connection to the machine it keeps rebooting.i havent seen any threads about this and was wondering if anyone can shed some light and lead me in the right direction.once again thx to all

does anyone have an idea.can it be its because i have software 4.3 on it presently.maybe thats why it reboots.when i unplug the eithnet cable it doest.its really odd
