Hi, I need some help to find out what is happening in my Airport network. I just bought 3 airports: 2 new double band Airports extreme and 1 "N" airport express. I have one of the Airport Extreme #1 connected to the DSL router and have configured the network, both 5 and 2.4 I have the Airpot Extreme #2 to expand the signal of the network (I realized that the Airpot Extreme as a bridge it only can replicate one of the networks 5 or 2.4. Is replicatiog the 2.4 network) I have my Express in the range of the second Airport Extreme #2 to expand the signal to another area. So far so good. The three Airports have the green light and are connected to each other (or that is what i see in the wireless clients option in the advanced panel of Airpot utility app) . However, when I go with my computer to the area that Airport Express should be covering, I have a really week signal even though I have the Airport Express right in front of me. (my iphone is not even able to detect the network from there) So I go again to the advance panel to see the wireless clients of the Airport Express and I see only the Airport Extreme #2. If i go to the wifi clients of the Extreme #2 I see that other Extreme #1, Express and my computer. So my conclusion is that for some reason Airport Express is not replicating the Airport Extreme #2 signal (if i configure the Express to build a network of its own i'm able to see it with my computer). I don't have anything connected to the Airport express, Any thoughts?
