I have a Linksys WRT310N and my HR22-100 is connected through a Homeplug adapter in the living room. I have internet connectivity, no problem. The issue is with my HR21-700 in my living room upstairs. I am trying to connect with a second Homeplug adapter upstairs and I can't get connected to the internet. The Homeplug adapter is plugged directly into the wall (not a surge protector), I get both green lights on the adapter but can't get connected to the internet. When I go a scan of the network on the WRT310N, it does not "see" the HR21-700 upstairs. When I do the "Connect Now" process, it says that I am connected to the network but not the internet. Any suggestions? Thanks.
