I have done some research but keep finding many threads without a resolution. I recently was given a dual 2.5 PowerMac G5 with the HD removed. It had been upgraded with an airport card. After installing a brand new Seagate HD and installing a retail copy of 10.5.6, everything appeared to be working fine. The airport card connecting as it should to my home network where two other macs connect with no issues. THEN, I ran software update which included the 10.5.8 updates and an airport related update. Now the airport card will not maintain a connection. When I try connecting and inputting the password, I receive a "connection timed out" error. Anyone have any insight? Also, I noticed that there is no external antenna attached, which apparently should be on this particular model. However, as I said, the wifi had been working fine prior to running the updates (which were rather hefty and were downloaded via wifi).
