I have currently have 2 extremes & 2 expresses, bought to extend my wireless network throughout my concrete walled house. The main Extreme which creates the network is at one end of the house since that is where the ISP cable is. I was hoping that I could daisy chain the airports to the other end of the house to cover all of it. After reading more it seems that each 'extend the network' airport is only extending the signal from the base station. Is this correct? If so how then do you get any more range than one 'extender' worth from your base station. Seems rather limiting if you can only extend the wireless signal once in every direction. I have heard of WDS but it seems very limiting in bandwidth & I lose the benefit of wireless 'n' Ideas? Thoughts? Suggestions?
