i am in the same boat, i just updated the systerm using yum update, and updated to the new kernel, 2.6.17-1.2187_FC, and my wireless doesn't work... the driver is installed , ndiswrapper -l shows the driver present, hardware working.... but can't enable it... i haven't checked my Realtek RTL-8169 Gigabit Ethernet which is my wired card, but my wireless is down under new kernel. so i have to login to the older kernel to make it work.... anyone else is having problem with wireless shutdown under new kernel update? any idea how to get it back to work? i might try to load the driver again... and check to see if even the wired nic card works or not... my wireless doesn't pickup anything.. basically i can't enable it at all ...
PS. i'll post an update here if i get it to work, for others dealing with the same problem.
