[Solved] no wifi with linux-pf kernel

Hi,

I just installed the linux-pf kernel from AUR and ran a new

grub-mkconfig -o /boot/grub/grub.cfg

Then, I noticed that my wifi didn't work anymore. I found out that the name of the device has changed from wls1 to wlp3s0. So I set

ip link set wlp3s0 up

and the LED started blinking. Then I started wifi-menu and the scan provided me all the usual access points. However, when I tried to connect to my access-point, the device went off again.

This is the error message:

Feb 09 11:25:56 localhost kernel: wlp3s0: RX AssocResp from XXXX (capab=0x411 status=0 aid=3)

Has anybody faced a similar problem? Im use a X200 Thinkpad by the way. When I choose the standard kernel, everything works.

Re: [Solved] no wifi with linux-pf kernel

I have similar problems with the latest update of wireless_tools 29-8 =>30.pre9-1 on kernel-netbook
does not recognize my wireless interface. For the moment I use the old version (wireless_tools 29-8) and everything works.
Try go back to the old version.

Thanks, but it didn't help. Still having the same problem with the older version - so I switched back to the newer one again.

Since the name of the device has changed, I wonder if the wrong module has been loaded...

Re: [Solved] no wifi with linux-pf kernel

The device naming is not based on anything to do with the device itself.  Rather, it is determined by the devices physical location within the machine.  So why the device changed in this way is kind of a mystery.

When you have network hardware issues (or hardware issues in general) you should also post information about the make and model of said hardware.  It is rather hard to help you when all one knows is that you have 'no wifi'.

Also, please fix your post to use code tags.  You can see how to do this by following the BBCode link below.

Re: [Solved] no wifi with linux-pf kernel

I see, I thought that the naming has changed due to a change in the kernel.

Well, I solved the problem - more or less. Since the X200 has a Core2 processor, I downloaded the linux-pf-core2 package. Now, I removed this package and installed the standard linux-pf package. Wifi worked instantly, which is a bit puzzling, because I always used to compile packages for the core2 architecture.

Anyway, I'll mark the problem as solved, because I don't mind running a standard kernel.
