Ok. So I've come home from college for the summer and set up my PC and iMac in my bedroom. However, the wireless signal from the router in the basement (a cisco m10 wireless n router) is very weak and cuts out frequently. I have an Airport Express and was hoping to use it as a wireless repeater/range extender, but can't seem to figure it out. I know there is no "official support" for use as a repeater with non-Apple routers, but is there a way around this? If so, how can I set up my network?
