Hello Everyone! My house has thick concrete/brick walls (dont know exactly) and I was wondering if the Airport Extreme with its 802.11n spec will be able to reach everywhere in my house. My current router is a Siemens Speedstream 802.11g. As far as I know its pretty crappy and unreliable. Its signal hardly goes through one wall and at two walls, sometimes it detects the network and connects for a few moments. I can measure and tell you how thick my walls are and how far away would the farthest point be from the router.
