DNS

Hi, I was wondering if anyone is able to help me.

I have version a atv 2 jail broken and was using unblock-us to view US Netflix. Everything was working great til a few days ago.

Suddenly the ATV boots up but gets stuck/frozen after starting up. If the network is disconnected, it will sit on the nitotv menu path after booting up but when plugging in the network cable it will display the movies menu. In Either case, the remote is unresponsive. I suspect the issue is associated to the dns being used and was wondering if there was either a way to fix it or alternatively a ssh command that can be used to set a new dns.
