Hello,

Phil, yes, I'm controlling it with NetworkManager (the wireless card refused to work without it in 5.1 and it still refuses in 5.3). I've stopped the "network" service at boot (NetworkManager was already starting at boot and wpa_supplicant was already stopped), but this didn't change anything (I guess the network service is unnecessary so it's good to turn it off anyway).

Urs, /var/log/messages says this about iwlagn at every boot:

Apr 24 01:42:09 localhost kernel: iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27ks
Apr 24 01:42:09 localhost kernel: iwlagn: Copyright(c) 2003-2008 Intel Corporation
Apr 24 01:42:09 localhost kernel: iwlagn: Detected Intel Wireless WiFi Link 4965AGN REV=0x4
Apr 24 01:42:09 localhost kernel: iwlagn: Tunable channels: 11 802.11bg, 13 802.11a channels
Apr 24 01:42:30 localhost NetworkManager: <info>  wlan0: driver is 'iwlagn'. 

dmesg says the same thing (starting at iwlagn), but without the last line. 

I tried deleting and recreating the wlan0 device in system-config-network, but this didn't help. Likewise, deleting and recreating the CERN network within NetworkManager's list doesn't change anything.

Thanks for your help.

I tried "yum install iwl\*" and it installed the microcode for the 3945 and 5100 cards (in addition to the 4965 microcode which was already installed), but this didn't fix the problem. My /etc/modprobe.conf now contains only these three lines:

How are you controlling the device - with NetworkManager?

Try stopping the network and wpa_supplicant services (at boot) and set 
the NetworkManager service to start at boot.
