Hi,
I run Scientific Linux 5.2 with kernel 2.6.18-92.1.6.el5 on a
Fujitsu-Siemens Amilo Si 1520. I have the Intel PRO/Wireless 3945 ABG
card. I noticed that the original installed configuration came with
mac80211 and support for iwl4965, but it seemed to have nothing for 3945.
# lsmod | grep iwl
iwl4965 105921 0
mac80211 117453 1 iwl4965
compat 7617 2 iwl4965,mac80211
So I followed the instructions here:
http://www.intellinuxwireless.org/?p=iwlwifi&n=howto-iwlwifi
to install the iwl driver for 3945, but when it came time to compile
iwlwifi-1.2.25, which I tried as root, I got a lot of errors.
After that I installed the older dkms-ipw3945 using yum following the
instructions at:
http://wiki.centos.org/HowTos/Laptops/Wireless?highlight=(3945)
but it too didn't work with the following symptoms.
The wireless appears to see that there is a network around, but doesn't
manage to connect to it if I run NetworkManager and select the wireless
network.
# iwlist eth1 scan

I'm not sure if it's relevant but if I boot up with wireless on and the
ethernet plugged in I get a whole bunch of
"hub 1-0:1.0: connect-debounce failed, port 6 disabled"
in the dmesg. This doesn't happen with when the ethernet is unplugged but
the wireless doesn't work then either.
I would be very grateful if someone would suggest a way forward.
Thanks,
Mark
