[SOLVED] network trouble (wlan stick)

scrawl · 2010-01-14 21:15:09

Hi everyone,

I just installed Arch through the net install cd. Weird thing is, while installing, wlan worked (how should I net install otherwise). I got it to to work with wpa_supplicant. But, on the installed system, it doesn't work. The stick shows up in lsusb, but there is no network interface ra0, like on the install cd! What could I have done wrong? I wonder why it works on the installer, but not on the real system The stick is from Logilink. Under Ubuntu, everything works out of the box.

P.S. I've already installed wireless_tools, net-tools, util-linux-ng, wlancfg, netcfg, wlanctl-ng, wlan-ng26-utils and inetutils in pacman, and executed modprobe rt2500usb as said in the wiki.

rt2500usb creates a wlan0 interface, not a ra0, so it is not the driver you used during install. What chipset does the device use?

Alright, I've found out there is probably a kernel regression leading to this problem. The solution should be to downgrade the kernel to at least 2.6.30.6. Is that possible in Arch Linux, or must I always use the latest kernel?

Hmm, interesting. Which driver creates ra0 then? And how do i find out what chipset the device uses?

Edit: I think the chipset is ralink.

Many people had problems with different ralink chipsets since 2.6.31. I think you can use the windows driver via ndiswrapper or fiddle around till it works. Perhaps this helps...

You can also downgrade your Kernel by using an outdated mirror or install the LTS Kernel (2.6.27 I think)

Thanks for the tip. I have downloaded a pkg.tar.gz for the old kernel. How do I install it now? I can't find it at the pacman manpage.

Edit: Found it
pacman -U /path/to/package/package_name-version.pkg.tar.gz

I will try it now, thanks for your help so far!

Yes! It works! I mean, graphics card and network, both at the same time

I installed the old kernel and network worked right away. However I had to install the nvidia driver through an outdated repository and then downgrade the Xserver. Maybe a bit dirty, but I'm just glad it works now

Arch Linux
