Sunday I updated my kernel to 128.1.16 (I had to reboot so it was time to update). No problems with wireless in my home. Monday I started traveling to IEEE 802 plenary, and I have lost my wireless numerous times needing to reboot. The symptom is the radio light goes off. Back before the kernel update, this would happen sometimes at home while on battery, and I would just press the capacitor sensor and turn it back on, and I would get my signal back. But so far this week, this has not worked. Nothing. No signal is gotten after turning the radio back on (for whatever reason this system decides to turn it off). I have tried restarting the network and NetworkManager and this has not helped (this use to help in the past when I saw this behaviour). There were some messages during the kernel update as follows: Uninstalling: fuse 2.7.4-1.nodist.rf (2.6.18-128.1.6.el5) (i686) -------- Uninstall Beginning -------- Module: fuse Version: 2.7.4-1.nodist.rf Kernel: 2.6.18-128.1.6.el5 (i686) ------------------------------------- Status: Before uninstall, this module version was ACTIVE on this kernel.

But despite that unistalling ipw3945 message, wireless worked, or it seemed. I am seeing log messages like: Jul 15 10:35:28 nc2400 kernel: ipw3945: Detected geography ABG (11 802.11bg chan nels, 13 802.11a channels) a lot. When I lost the wireless and tried to restart everything I saw: Jul 15 10:37:27 nc2400 NetworkManager: <WARN> scan_results_cb(): could not get scan results: An error ocurred getting scan results.. I really cannot deal with frequent rebooting. Can someone point me in a direction to fix this?

You want to use iwl3945 instead. Please follow the instructions on this CentOS wiki: http://wiki.centos.org/HowTos/Laptops/Wireless Akemi

Later tonight I will head over to the wired cafe here (they have a whooping 8 wired drops there!), and switch drivers. Thanks.

On this HP 2400 I have only gotten the suspend to swap working, and I can't loose that. Lights I can get by without; for some time in 5.1 or even 5.2 I did not have them.
