I got arch working fine in my Acer laptop. So I wanted try arch in another Lenovo 3000 N100 laptop. All ok except the wireless network connection. I tried out the method explained in wirelss wiki and also tried thro' gnome-network manager. Here are the out puts

I would like to fix this and expecting your answers, please,,
Thanks to all. After going thro' various forums and wiki I got this problem solved. As given in the wiki I have created separate network profiles, put in the Networks line of rc.conf. in the wireless profile I included DHCLIENT=no / SCAN=no/ QUIRKS=(prescan preessid). In the DEAEMON banged all other network modules and included network-profiles. These steps solved my issue. I also read that iwl3945 working will be difficult with channels >=10. But not the case with updated driver.

Have you tried connecting manually?
# ifconfig wlan0 up
# iwconfig essid <insert_essid> (more configuration and security options should go here)
# dhclient wlan0
Zl.

yes but not working. also I tried iwlist wlan0 scan the result is no scan results. I could not figure out. I tried with ubuntu live CD and drivers loaded are the same.
It works fine for some time after unloading/loading the modules again using modprobe. The work around for this is to use a bash script as given in this forum. Is there any way to make it stable. (netfg and gnome networking did not work in my case, may be an isolated issue, others can post their experience with Intel 3945ABG wireless).

My mother-in-law's Lenovo N200 (I think) also had this problem, after upgrading from Kernel 2.6.25 to 2.6.27 (She leaves it a long time between upgrades ) I use netcfg2 on her laptop. It kept on saying "Wireless Association failed". I fiddled around for ages, even tried ndiswrapper with no success, before I noticed a small quirks section in the netcfg wiki.
After I added:
QUIRKS=(preessid)
to the netcfg profile, it worked straightaway.
It seems a bit strange, this particular issue. My Dell uses the same wifi card, and I don't have to use the QUIRKS parameter.
I hope it works for you.
