[Solved] Another newbie wireless problem:

I'm helping my friend set up an arch system, and I can't get the wireless to work...

I have an Intel 3945ABG. I was using wpa, and after not being able to get it to connect, I disabled the wpa and added his wlan0 to the allowed device list.

I've tried setting everything up by hand (as per the wireless setup page), using netcfg and using wicd, both with wpa (using wpa_supplicant) and with the network "open".

When using wicd, after spending a while trying to authenticate, it just connects to the wired network; when using netcfg with the wpa network, I got an error "wpa_supplicant did not start, possible configuration error". Otherwise, it "seems to connect" but no signal is getting through.
The router is broadcasting, and I can see it from my computer; and it is giving the computer a dhcp lease (unless both the computer and the router are lying to me )

My (current) modules and daemons lines in rc.conf are

MODULES=(slhc tg3 iwl3945 snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-hda-intel soundcore !pcspkr)
#...
DAEMONS=(@crond syslog-ng !netfs !net-profiles hal fam gdm dhclient wicd network)

The interfaces and routes lines are empty.

Any ideas?

Re: [Solved] Another newbie wireless problem:

I have the same chipset and it works fine for me.

Do you have the firmware installed?

pacman -S iwlwifi-3945-ucode

Also, I don't think dhclient is a daemon?  And you should disable the network daemon as well, if you're using wicd.  (Should read !network)

Yeah. I made sure I had those first. I just reinstalled them in case, but to no avail. Or wait, is that the firmware or the drivers? (Or are those the same?).

Ah, I had dhclient in there because I saw somewhere to use it instead of dhcpcd. And, right... I knew that should have been disabled... oops.

Hmm... I'm going to see if I can get it working with a static IP. And... it works.
Cool... except I can't just change the router settings everywhere the computer goes.

So, why wasn't it working, even though it was getting a dhcp lease? I wonder if it is a problem that deals with my router, rather than the computer... I'll get back to you guys when we can test it on a different network, and see.

For now I'll delay posting the little [solved] tag.

Edit: nevermind... I'm finally connecting to the router, but nothing is going through the router. However, this computer (running OSX) is obviously getting internet through the same router.

Edit again: I changed teh settings back, and tried giving the computer a dhcp lease again, and now it works. I think it was a router problem?
