Kernel 2.6.13 WLAN Problems on Fedora Core 3


Hi,

I updated to the 2.6.13 kernel and I'm having alot of trouble gettng my WLAN setup properly.

I have a D-Link 520 (or something close to that, It shouldn't be too important for this problem) and I'm using the linux-wlan-ng-0.2.1-pre26 from http://www.linux-wlan.com/linux-wlan/ .

I'm running Fedora Core 3.


Originally, I was using the generic kernel that came with Fedora (2.6.9-667).

I installed the drivers mentioned above.

modprobe prism2_pci, dhclient wlan0 and all was well and good. My connection was setup and ready to roll.

When I booted into 2.6.13 for the first time I :

Recompiled the drivers for the new kernel.

modprobe prism2_pci, dhclient wlan0

I get an IP address and it sees my AP. I am able to ping my AP, the other machines on my network and www.google.com.

Unfortunately, I am unable to view web pages in Firefox or Lynx, use gaim or any other internet related program.

Here is my ifconfig from my 2.6.13 kernel :

lo Link encap:Local Loopback

Here is the iwconfig:

lo no wireless extensions.

Warning: Driver for device wlan0 has been compiled with version 18

Some things may be broken... Note : I tried using version pre17 and it did not fix the problem

Also, I tried a 2.6.12 kernel and it didn't work either.

If anyone has any information that might help me, I'd really appreciate it. I'd like to be able to use my iPod, my video card drives and the internet all in one kernel.

Thanks,

billspork

Also, if any more information is needed let me know.

did u try a ping test to your router ip, then an external ip address, and check your routing tables as well as /etc/resolv.conf, and do a traceroute..sounds like a routing issue to me

from your wifi router, you should be able to try ping your client 192.168.1.101, check to make sure mac filtering is off too
