[SOLVED] wlan problem

[Miax]

hello, i'm pretty new to linux. my problem is so.

i have read the gentoo handbook and started installing gentoo linux x86 2.6.34-r6 using genkernel on my thinkpad x61, emerged wpa_supplicant(for WPA2-Personal), configured the bootloader and rebooted. but then the wlan device was not detected. ifconfig -a shows only eth0 and lo. what can i do? i write down my /etc/conf.d/net here.

/etc/conf.d/net
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"

You first have to make sure the device is identified. Running wpa_supplicant and its configuration is just a later step. Please post your "lspci -n", you probably forgot to install the firmware.

[Miax]

thank you for the reply.

# lspci -n
-bash: lspci: command not found

but restart with livecd(livecd detects wlan0 already)

i think if i forgot to install the firmware i must reinstall it, right?

i didn't see the firmware-installation part in the gentoo handbook.

[Kobboi]

lspci is part of the sys-apps/pciutils package. Please provide the complete lspci output, probably can't tell anything else than what PCI bridge you are using. Firmware requirement depends on your specific wireless card and not all drivers need it, that's why it is not in the handbook.

If you paste that output on this website, you can see if your hardware is supported by the kernel, and if so, by which driver/module, in your case the iwlagn driver. Do you have that driver enabled/loaded?

[Kobboi]

And if you have, you likely need the following:

[Miax]

thx.

i've emerged the firmware and now it is detected by ifconfig.

but i did

# wpa_supplicant -d -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -Dwext

then it doesn't terminate. (seems like infinite loop)

[Kobboi]

I don't usually run wpa_supplicant myself, I let the net.* scripts handle that.
If you worry that there still is a hardware related issue, try temporarily disabling your WLAN security
If you need wpa_supplicant support, someone else is probably more capable to help you than I am

[Miax]

problem solved. i ignore the infinite loop and added net.wlan0 to the default runlevel

and it worked.

thank you kobboi.

[Kobboi]

I also don't see why wpa_supplicant should terminate. Certain security mechanisms require rekeying, which appears to be done, in userspace, by wpa_supplicant.
Glad to have been of help
