I have Roku XD, model 2050X. I am using D-Link 615 wireless router. I have reset and re powered Roku. I have changed batteries in remote. I have reserved a specific IP address in the router. I have added both my PC and Roku MAC address to the 2 added IP addresses in the router. Roku sees my wireless network but will not recognize the Passphrase which I KNOW is correct. Other PC, cell phone and other devices connect wirelessly without a problem. Also the remote will not function properly. ( IE) will not go the the home page when that button is pressed. I am out of options. Can anyone assist??
