Re: Powerline Networking adaptors (EoP)?
I can't say whether they'll work thru a UPS or not but I can say that these type of devices are very iffy. I tried a different brand (Belkin I believe). The only place in my house I could get them to connect was between 2 sockets in the same room, same wall, 10 ft apart. YMMV, maybe there is something different about the wiring in my house but I doubt it.
If you get these, report back to say how they worked for you.
