I have IMAC (10.5.8)with ethernet and wireless....and just purchased a MAC Airport Express. I hooked it up directly to the comcast modem and it works fine as a wireless for the MAC. I can see the wireless network I named on the iPAD 3 wireless but cannot seem to find the right setup of wireless protocols for the IPAD to see and operate on the wireless signal it is finding. I can see every neighbor's wireless stations and my own....but I cannot get it configured right.
I called COMCAST and got an idiot....who said. Call Apple. Has anybody been through this or is perhaps Apple Airport Express not compatible with COMCAST? The Apple Store said it should work.....and it works well on my MAC Work Station on Wireless connection to my Comcast modem....what the hey?
