Problems with wireless driver

Hey everyone,

everytime i try to install Arch on my Laptop i have the same problem with the wireless driver.

I install wpa_supplicant, ipw2100-fw, and iw (because the iwconfig package, as described in the "wireless setup" article).

And then i follow the wireless setup  article and the computer gives out error messages:

#: rmmod ipw2100
      -> ERROR: Module ipw2100 does not exist in /proc/modules
#: modprobe ipw2100
     ->
#: rmmod ipw2100
     ->
#: modprobe ipw2100 rtap_iface=1
     ->FATAL: Error inserting ipw2100 (/lib/modules/3.0-Arch/Kernel/drivers/net/wireless/ipw2x00/ipw2100.ko.gz)

the only similiar problem i found was this but it couldn't help me: https://bbs.archlinux.org/viewtopic.php?id=111646

i would really appreciate if you help me.

Re: Problems with wireless driver

It is easier for someone to help you, if you provide the exact wifi-card you use by pasting the relevant line the Intel device of:

lspci -nn

Further, have a look in

dmesg

if you see the firmware being loaded ok for the card. paste the relevant output here (with code tags), if unsure.
You write about having installed ipw2100-fw but then modprobe ipw2200, maybe you need to use ipw2200-fw instead for the card.

Re: Problems with wireless driver

The modprobe ipw2200 was a typo I'm sorry for that.

lspci -nn

Re: Problems with wireless driver

That lspci shows you have a Wireless-N 130 card, not ipw2100. So you should be using the iwlwifi driver.

Also, lspci in a VM is useless, as it'll show the virtual hardware of the VM, not your actual hardware.

Re: Problems with wireless driver

Hmm ok,
So where can i look up which exact driver do i need, because the setup manual says that 3 different iwl drivers exist.

Thank you,
and sorry for being so noobish.

Re: Problems with wireless driver

Err, I said which driver you need - iwlwifi

Also, most of the time the driver is loaded automatically, I'm sure that's the case here too.
