I am having trouble getting my receiver to connect to the Network. The last time I used network functionality on it was a few weeks ago, and when I went to connect today it just went to black screen and in really tiny letters on the front of the receiver the word "Net" blinked. I tried going to the initial setup and doing the network connection test, and it said no connection was available. So I took the ethernet cable connected to my TV and switched it with the one connected to the receiver. They are both plugged into a TP-Link network switch. The TV could still connect and the receiver still could not. Don't really know what else to do but a full factory reset which I don't really want to do, as I don't fell like doing Audyssey all over again. Any other suggestions?
