My home network consists of a couple of Ruckus Zoneflex 7982 802.11n access points with an enterprise firewall sitting in front of a Comcast modem. I have three TiVo units and been using TiVo for many years and have never had any wireless issues - until I bought the Roamio Plus. Strangely the basic Roamio unit i also bought is having no connection issues.
After a reboot of the Roamio Plus everything works fine, and the wireless connection comes right up. After a few hours, however, the connection appears to fail and I get the dreaded message that the router has failed or the router is not reachable. I tried moving to a static IP address but this did not resolve the issue. The only reliable resolution to this problem is a reboot of the unit.
I opened a case with TiVo support weeks ago but there has been no resolution. I realize I could buy the old style TiVo 802.11n adapter which connects to the Ethernet port however I have been hoping that this would not be needed.
