I have a main router Netgear DGN2200 then I have a cable from the LAN to a Belkin powerline adapter. Up in my loft I have the other powerline adapter connected (via LAN) to a second router, a Netgear wnr2200. I have it all connected correct with the dhcp turned off on the second router etc.

Heres the problem. The second router doesn't work over the powerline adapters. When the two routers are connected direct via one ethernet cable the second router works fine with the exact same settings. I don't get it.

Anyone else had this problem?

This question came from our site for system and network administrators.

While your question is interesting, it might be more suited to SuperUser, here we deal with business type questions and hardware. – NickW May 30 '13 at 10:16
Since you've said "loft" I'm going to assume you're british. Are these two Powerline devices on different ring-mains? Which would mean there's circuit breakers between them? .. I've seen circuit breakers interfering with Powerline hardware, as they work by having some inductors on the line, which can cause untold mischief with the frequency that Powerline adaptors operate at. – Tom O'Connor May 30 '13 at 10:36
Sorry NickW. Thanks @Tom O'Connor that sounds like it might be the problem. I'll try it on the same ring. They work fine if I plug the second cable straight into my computer rather than the 2nd router. Will just have to get a switch instead. – AspenMIT May 30 '13 at 10:44
I've abandoned Powerline at home numerous times, because it's very dependent on pretty perfect cabling between the adapters. Something that's very difficult in both modern (because of inductive breakers) and old houses (because of old wiring). ISTR that american houses are wired fundamentally differently, but IANAElectrician. – Tom O'Connor May 30 '13 at 10:46
@TomO'Connor It's annoying that it's not working. Glad I didn't buy them and just borrowed them. It's annoying also because the second router works up there if I connect the cable into the WAN and have it as a separate network. – AspenMIT May 30 '13 at 11:36

It sounds like you have already identified the problem. The powerline adapter

Powerline adapter's are notorious for being unreliable and flakey. Searching google for "powerline adapter problem" returns over a quarter of a million hits.

Netgear has a troubleshooting guide that I'll link here

If absolutly can not run a cat 5 cable, as a last ditch effort try moving your router to a different subnet. I've seen many inexpensive SOHO devices that can't handle classless routing.
