I have two DVR receivers. I have an ethernet connection for one, but not the other. I was going to run a phone cable under my house to get to this receiver but that proved problematic. Instead, I can run a phone cable across the floor but don't want to leave it out because of kids, etc. Is there a way to program the update so I don't have to leave the cable out? If so, how many times would I have to do this a month to negate the programming access fee?
