My roommate and I both have Macs and a while back I purchased an Airport Extreme. All was working fine, but then I believe his computer wasn't working properly, so we tried doing a hard reset of the Airport. After doing so, it appeared that it still didn't work, and I just assumed that it was his computer which was having problems. Earlier this morning he was using his computer for something and I had to reset, as I reset, his computer connected to the network and mine would not connect anymore. It appears that maybe there is a setting that does not allow more than one user connected wirelessly at a time? I am completely puzzled as to what setting it would be, if any. Any help would be greatly appreciated. Thanks.
