I have an IBM t42. When I connect to a wireless network, it briefly (about .5 seconds) attempts to obtain an IP, then goes back to totally disconnected for about 15 seconds; that cycle repeats ad infinitum. I've tried two PCMCIA cards, and the built in wireless, on multiple networks. I've reinstalled Windows, and tried Linux. I have no idea what the problem could be, this computer just will not connect to a wireless network. BIOS is updated. Am I missing something?
