On the Bestbuy website they market the airport extreme as having the capability to become a range extender and the guy in the store said it would work with a linksys. The Linksys is a WRT150N. I have the airport extreme set-up in my room and it has a solid green light. When I go into the set-up for it I click join network and It sees the linksys and I select it and it says everything is working fine but it stays on the green light and the signal isn't being extended. Help?!
