I have a customer that originally had a home wireless network that was working fine with 3 PCs and 1 new iMac. Their wireless was set up with just the default SSID of linksys and no security. They were having some problems with the wireless reaching some areas of the house so I added a second AP to the network. I kept the SSID the same and changed the default channel. So now one AP is on channel 1 and the other is on channel 11 with same SSID and still no security. All the PCs are working great with Very Good to Excellent signals in all locations. However the iMac will now not connect to the network. Does anyone know why? I know next to nothing about MAC.
