I have also used Ethernet over Power lines, NetGear, the version that
has the ham bands filtered... Worked fine... I SWL, so I eventually
got rid of them...
I was helping another ham look for RFI, and noticed that the RFI quit in
the ham bands, (he was a SWL as well). I mentioned this and said it
might be Ethernet over Power line, he looked across the street, and a
truck from a local Internet company was in the driveway...
Turns out the neighbor worked for an Internet company, and was using
Ethernet over Power lines...
