Wlan0-interface & Wlan-driver gone?

Recommended Posts

In all my experimenting yesterday I must have done something wrong ...


Today I suddenly can't find my Wlan0-interface. It's just gone overnight ... Vanished from the network-center. I've tried to setup a network interface, but when I click wireless and then proceed all I get is use Windows ndiswrapper. And I know there used to be an Intel 4965-option there when I booted Mandriva the first time.


Three things I found so far:

  • There appears to be no iwl4965.ko.gz-file in /lib/modules/
  • When installing iwlwifi-kernel-desktop586-latest i get unsatisfied iwlwifi-kernel-
  • it shows up correctly under the 'browse and configure hardware'-screen


System specs: Mandriva 2009 Powerpack on a Acer Aspire 5920 with Intel WiFi 4965 AGN .

You will not find the iwl4965 module in that kernel. Have you installed the iwlwifi-4965-ucode package from the official non-free repo? It contains the firmware you need for the iwlagn module that you should be using

[root@halfway greg]# modinfo iwlagn | grep -i 4965
alias:		  iwl4965
firmware:	   iwlwifi-4965-2.ucode
parm:		   fw_restart4965:restart firmware in case of error (int)

Here's some more info on this: intellinuxwireless.org


So make sure you're using the iwlagn module. You can check with

lsmod | grep -i iwlagn

If it's not loaded, you can load it with

modprobe iwlagn

- The iwlwifi-4965-2.ucode is installed.

- lsmod | grep -i iwlagn does nothing


And modprobe

[root@localhost maarten]# modprobe iwlagn
FATAL: Error inserting iwlagn (/lib/modules/ Invalid argument

Try using the parm option. First, make sure it's not loaded with

modprobe -r iwlagn

then load it with

modprobe iwlagn fw_restart4965=1

if that works, then you can add that option to an /etc/modprobe.d file.

I found a message that the laptop has



Gigabit Base-T LAN 10/100/1000Mbit, V.92 modem, WiFi 802.11a/b/g, 802.11n WiFi


So, like WIFI and I have RALINK.

You must have Firmware







This firware find in RT Drivers. Copy this file to /lib/firmware

System automatictly loading driver rt2x00pci to memory.


Paste here as root


lsmod | grep rt2x00pci


Driver rt2x00pci is use in newest kernel. Older kernel use rt61????? forgotten..Lex

One of the latest card company Ubiquiti Networks, based on the Atheros chipset AR9160 with DFS SUPPORT. This is a card which works in the standard IEEE 802.11 a / b / g / n. Particular attention should be paid its operating modes, namely the ability to work in the four-mode power at 24dBm according to specifications. Unfortunately, for now work on Linux, you must wait until other manufacturers implement standard "n" in your solutions to the wireless network.


NOTE - the card does not work in the Mikrotik


Atheros IEEE 802.11n ath9k driver

Luis Rodriguez (now no longer an employee Atheros) linuxwireless presented to the new wifi driver on Linux "ath9k" (not to be confused with the "ath5k"). This driver supports all Atheros chipsets capable of operating in the IEEE 802.11n (draft). The driver is fully Open Source.
