Hi, I have a Dlink DIR-600 wireless router in my house, and I have an ethernet cable down to my basement (which does not receive the wireless signal very well). Then, I tried connecting an Airport Express to the ethernet port in the basement and set it up as an access point (no routing!) for the basement. But it does not work, I get error messages from Aiport Utility and the Airport Express flashes amber. I tried "extend" or "join" a wireless network, but that only tries to extend/join wirelessly, right? Trying "set up a new network" works, but then I get a new logical network (new SSID). And then I have to change network on my MBP if I move around. So my question is: can the Airport Express extend a network that it connects to over the ethernet cable? Thanks for any help!
