My Roamio plus is usually connected by Ethernet. I unplugged the cable to use the cable elsewhere. Can't connect, dhcp seems to be issue. The odd thing is wifi works on many devices including my Bolt. As soon as I replace the cable everything is fine. Not a big issue unless I have to use the WiFi at some point. I have an Xfinity gateway. I am an anal retentive who wants it to work even if I don't need it.
