I just got back from a trip to find that my wirelessly connected Roamio was complaining of having no guide data. Looking through the settings revealed that it had become disconnected from my wi-fi. The list of networks did not show my 5GHz network, to which it had previously been connected. I verified that other devices were having no trouble on the 5GHz network. Rebooting the Tivo, as well as toggling the wi-fi off and on again, had no effect. The Tivo did still list my 2.4GHz network and connected to it without problem. My question for you: is it possible for the Tivo's 5GHz radio to fail while the 2.4GHz counterpart keeps on working? Secondly, am I the only one this is happening to, or was there some bad update that's crippling 5GHz radios?
