Don't you have to have at least one wired PC to configure the network and make it work? I think some routers are picky and won't allow control panel access if you are on a completely wireless network. For security reasons too. There has to be a hard connection somewhere. Someone correct me on this as I am not 100% sure. In my case as an example, I have my main desktop PC right here in the same room with my cable modem. That one is using the CAT5e cable so no wireless is involved there. My laptop is wireless and have built wireless adapter already so I can go anywhere or even outside the house and pick up my wireless router signal. So neat.
