Following the recent weather events in my village (see related question) I'm looking at better power protection for my equipment, specifically a UPS and a set of replacement surge protectors which, it turns out, have all been worn out.
I see some of the more expensive surge protectors include phone and network protection also. The backbone of my home network is a Netgear Powerline-type connection, with just two adaptors. How can I most effectively protect this connection? I believe the Powerline adaptors have to be plugged directly into the wall, so protection on that side of the circuit is not possible. However, would it be useful or effective to protect the CAT-5 cable via one of these surge protectors? Or is the network and phone protection feature just marketing fluff that's not actually needed?
