my Roamio is connected via its built in wireless to my N home network and shows a 70% signal strength and is updating normally each day. My old Quad premiere elite tivo I call "Quad Elite" is connected to my home network via the wireless N tivo branded ethernet adapter. In "my shows" on the Quad Elite at the bottom of the list I can see my Roamio and delete programs remotely. lately however on my Roamio, in my shows at the bottom it has an exclamation point to the left of the "Quad Elite" with a message that the "Quad elite cannot be found". it used to be there, just not the past few days. I have rebooted both tivos several times, and made sure on the website under my dvr preferences that "video sharing" and "allow video downloads" are both checked any thoughts before I call tech support?
