wlan0 has gone

Hi I was having trouble with my wireless after a kernel upgrade so I thought I would try compat-wireless but during my mucking around I have managed to remove the wlan0 interface.

Here is the hardware info:

lspci:
jonesn-laptop:/home/jonesn # lspci | grep -i wireless
06:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN Network Connection (rev 61)

I guess I have installed the wrong driver or the like, can some one point me in the right direction for reinstating the wireless interface?

Thanks for your help.

Have you actually been in to Yast - Network devices - Network settings- to try and configure/re-configure??

Hi

Yes I had, below is the message appearing in the network settings window. The firmware is present I’m just wondering if it’s incorrect. I’ve tried removing and reinstalling the iwl4965-ucode package but the wlan0 interface (or any wireless interface) still seems to be missing.

Message

PRO/Wireless 4965 AG or AGN Network Connection (Not connected)
BusID : 0000:06:00.0

Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details.

Thanks

If you have a read here it may help
HOWTOs - openSUSE

Well I managed to get the wlan0 interface back but I think I’m back to where I was to start with when I run:
**
ifconfig**

jonesn-laptop:/home/jonesn # ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory
**
In dmesg**

iwl4965: iwlwifi-4965-2.ucode firmware file req failed: Reason -2
iwl4965: Could not read microcode: -2

Under /usr/lib I have iwlwifi-4965-1.ucode but not iwlwifi-4965-2.ucode I guess this causing the current problem. Renaming the file doesn’t work.

Has anybody come across this issue before?
Thanks

#6

Just though I’d post how I got around this in case others have the same issue.

I grabbed the mircocode for the 4965 from here

I then copied the iwlwifi-4965-2.ucode to /lib/firmware

After that I followed the advice from this post and after changing a few settings using iwconfig I was able to get my wireless working.

I have the same problem. I started a new thread (only just found this one) and figured out what you have so far but i hit a dead end. I’m using WPA encryption.

I get:
