Re: wireless troubles

Well, the ipw3945 is your wifi card. (Intel Pro Wireless 3945, if I remember correctly) From what I'm reading - you should be using the iwlwifi driver. I believe that is offered to you through the package called 'iwlwifi-3945-ucode'. This package is in the core repo. Try hooking up to the 'net through Ethernet once and installing. I'm not quite sure what to do after that but I'm sure http://intellinuxwireless.org/ or http://wiki.archlinux.org/index.php/Wireless_Setup will tell you.

(All of this was found using Google - please attempt to search before you post.)

Re: wireless troubles

What can't you figure out, exactly? Does `iwlist scanning` produce any useful output?

Re: wireless troubles

I don't know if this will work.  It's not very elegant but it worked for me as  I have the intel 3945 card as well.
From the beginning:
1) make sure you have wireless tools, netcfg and iwlwifi-3945-ucode installed
2) Make a profile for netcfg
3) go to rc.conf and delete ipw3945 from modules, but keep iwl3945.  Set up the wireless section like they tell you to do in the wireless wiki and set up netcfg2 like they tell you to do in the netcfg wiki.
- you might need to comment out eth0 and put a ! infront of it in interfaces, i don't know if its required but I did

What happens on my computer is I noticed I always needed to run netcfg2 twice in order to connect.  So this way it tries to connect using network and fails, then it tries and connects with netcfg2 and is usually successful. 

Another "solution" that worked for me was to make 2 identical netcfg profiles but with different names and connect to them both.  On the first connect the first profile failes to connect, but the second profile connects.  I like the first "solution" better because I can load network and then netprofiles loads and connects in the background.

I'm new and this probably is just circumventing a bigger problem, but using this method arch linux is the first linux distribution where I actually got the intel 3945 card to work without using ndiswapper and without having to connect to the internet.

I dont' want to hijack the thread, but is there any way to run netcfg multiple times until it connects?

Thanks
Jeff

Re: wireless troubles

@ xhhux

Try this (if you're not a extreme purist), it works:

# pacman -S iwlwifi-3945-ucode
# yaourt -S compat-wireless
- in /etc/rc.conf, write MODULES=(iwl3945 ... others modules...)
- install and configure wicd or another wireless manager
# reboot

Nope, and there never will be. If it's not connecting, there's a problem, and that problem should be fixed instead of worked around.

Please take a look at the netcfg2 in [testing]
If that doesnt solve the problem, try some of the quirk options: http://wiki.archlinux.org/index.php/Net … evelopment

Re: wireless troubles

I just swapped my Atheros card for an Intel 3945 today, I tried the iwlwifi method, didn't work at all for me. Installed the older ipw3945 driver and it worked first try. I might tinker with iwlwifi more later, I just wanted wifi up now, if ipw3945 wasn't going to work for me, I was going to use ndiswrapper.

`iwlist scanning` works, too. Did you try it?
