Or, to be accurate, what a TiVo cs rep told me to do that fixed it. I have two TiVos, a Series2 80-hour and a Series2 Dual-Tuner 180-hour. The S2DT is connected by ethernet to my router, the S2 has a TiVo usb wireless adapter. When the 9.1 update went out the two boxes stopped seeing each other in Now Playing. Once in a while the S2DT would see the S2, but opening it would tell me that it was empty (paraphrased, badly), which was not only not true but was a message I'd never seen even when it was true. I tried restarting both boxed, manually updating, redoing the network setup. No good. I called TiVo cs and described the problem, learned that (as we know) there have been a LOT of glitches with the 9.1 update, especially networking issues. The following is what she had me do which resolved the problem. 1) Disconnect power from both TiVos 2) Disconnect power from my router 3) Disconnect the ethernet from the S2DT and the usb adapter from the S2 4) Wait at least 1 minute (I waited 10, reading email and whatnot) 5) Reconnect power to both TiVos, wait until they're up and running 6) Reconnect power to the router, wait for it to reconnect and settle down 7) Reconnect ethernet to S2DT and usb adapter to the S2, verify each can see the network 8) Manually tell each TiVo to connect to the TiVo service All done, problem solved.
