I have a Premiere in a back room using the Tivo Wireless G USB adapter for wifi. It works great, never loses signal or connection to router. I have a Roamio in same room as router and much closer and it is constantly losing connection. I have an extra Tivo Wireless G USB adapter. Can it be used on the Roamio? Is there some way to disable the internal wifi? Both units are running TE3. They are on separate TV antennas. One gets some of the channels, the other gets some other channels. I frequently record on one and watch it on the other TV, so I need decent wireless connecton. Ethernet or Moca are not an option. Thanks.
