When our satellite was recently converted from Direct to Dish, the installer entered the wifi password into the television receiver box. What do we gain from having the two tied together? One reason I ask is because in the next couple of days, a new router is going to show up and I'm wondering if we should ask the guy to tie the two together again as they are now. Would have been nice had the Internet been left alone since we were with Century Link with Direct and will be again with Dish. TIA
