I had an issue after activation and connecting the Roamio. My TiVo mini was previously working fine with my XL4, but for some reason I was getting a V70 error saying that the mini could not find a tivo on my network. TiVo support had me do several force connections on the mini and the roamio, none if which resolved the issue. After about 45 minutes on the phone he asked me to give it 3 days to see if the issue resolves itself. I really wasn't too concerned because I don't use the mini that much, so I agreed to how it a few days. After hanging up, I decided to restart the Roamio. Restarting the roamio resolved all issues immediately.
