OK, continuing the talk about Minis falling off the network... My mini is hardwired to the router, but it is through not one, but two TPLink switches. The Roamio Pro is wireless. The Mini will stay connected for a day, maybe two, before everything has to be restarted. This whole setup has been running only a week so I don't have a lot of experience with this particular setup. When this happened Tuesday, I restarted the network and everything was fine. This morning when it happened, I had to restart the Roamio Pro as well to bring things back. Any thoughts as to whether it's more likely that it's the Roamio Pro wireless connection or the switches that are causing the problems? Many thanks!
