The new S2DT is wired to the router, the older S2 is on a wireless adapter (not a TiVo adapter...). The wireless adapter shows excellent signal strength (around 85%). I've transferred one or two shows in near-real time since setting it up on Thursday, but since about midday Friday the transfer rate has dropped to a crawl. A 1-hour TV episode was going to take around 18 hours if I hadn't cancelled it. I've rebooted both TiVos (didn't expect the transfer to abort and start over as part of the process, though). Suggestions? It's not feasible to wire the remote TiVo to the router. I've got a TiVo wireless adapter on the way, but the plan was to use that on the one that's wired, not to replace the other wireless adapter... ETA: Both units are running 8.3, so it's not a Fall Update thing.
