Since these are on the LAN, packets are routed by MAC address and you'll have to ask how to clear those devices so they'll learn the new network. Normally I'd look in the manual for folk but the manual was elusive.
After these are reset, which may be as simple as removing from power for a few minutes they should work.

Finally dumped the Linksys router for a new Medialink MWN-WAPR300N router. Everything works great except my Linksys Powerline XAV2101 adapters.
Working are: wifi, wired hookup to Samsung smart tv, and wired hookup to Tivo.
It's hard to believe that the Powerline adapters may be incompatible with the router.
To check the Powerlines were working well, I reconnected the Linksys and voila, all is fine (that's how I am connecting here).
Anyone have any thoughts?
