hi, I am having problems with my a780. It is connected to my router and the orange and green lights are on the Ethernet port but the box still doesn't seem to have access to the network? when I go to s/w update it just sits there saying 'searching new update' and doesn't do anything else.i have a second a780 and when I plug it in in the same place as the other it works fine so the router, cables etc etc are all ok and it must be box related.has anyone had this before and knows how to fix it? fta works fine it just doesn't unscramble the pay channels (just like the Ethernet cable isn't plugged in? thanks
