Just a quick think I want to check before I put down some cash - I'm going to get a set of PowerLine adapters (this or similar) and I noticed that they specify that it works with a router. But as half my phone lines have died, I need to have a modem downstairs, and the router upstairs for the best signal. So, I was going to have the ethernet going from the modem to the PowerLine, and then coming out of the second one into the router, and the wireless broadcasting from the router. Basically - will this work? Thanks in advance!
