I am really glad it worked out for him. I have still not been able to figure out my situation. I think I have a similar problem, but not the same. The problem with my setup is that, when I connect the actiontecs to my main router, I lose internet connection wirelessly from my main router. What I do not understand is that my main router is before any of the actiontecs and all wired connections connected to my main router are working fine. But so far, I have only been able to have 1 active wireless connection working and connecting to the internet. I have 2 laptops and an iphone that I would still want to be able to connect wirelessly. But I can consistently get only one of them to connect and get to the internet.
My streaming between the actiontecs and the devices attached to them is working fine without any problem. I am able to view and watch HD content on my Media center PC upstairs from my XBOX 360 connected downstairs (thru actiontecs) and thru a linksys extender in my Master Bedroom (again connected through actiontecs). Right now, I have my wife's laptop connected wirelessly to my main router and she is able to get to the internet. But I cannot connect my laptop or my iphone. I get an IP address and all, but cannot connect to the internet.
It looks like I am so close, yet cannot figure this out. My router is Netgear WGR614. I also have a Motorola surfboard 5100 modem. Also, I don't think I have an amplifier as there is no power cord connected to the main splitter in my basement. This is where the main cable line comes in. What else should I check. What might I be missing.
