SUSE Linux Enterprise Desktop 11 Service Pack 1


When running SLED 11 SP1 on a Dell Latitude E6410 the wireless connection will continuously connect and disconnect.  This can be seen in the /var/log/NetworkManager log:

Feb  6 10:41:15 SLED11SP1-Test NetworkManager: <debug> [1291657275.669197]
periodic_update(): Roamed from BSSID (none) ((none)) to xx:xx:xx:xx:xx:xx

change: 8 -> 3
Feb 6 10:42:44 SLED11SP1-Test NetworkManager: <info> (wlan0): deactivating
device (reason: 38).


To resolve this issue use the following steps:

1. Download the following firmware update for the E6410 wifi adapter:

NOTE: At the time this Technical Information Document was created version was available.  Any version greater than should also work.

2.  Update the iwlagn-6000-4.ucode file in /lib/firmware using the update downloaded in step 1.

3.  Type

   modprobe -r iwlagn

To unload the currently loaded driver.

5. Create a /etc/modprobe.d/50-iwlagn.conf  file that contains the following:

options iwlagn disable_hw_scan=1


  modprobe -v iwlagn

To reload the driver with the new firmware and the new option. 

You can verify the new firmware is loaded in the /var/log/messages.

You may see the following error message in the /var/log/messages after making the changes:

avahi-daemon[2924]: Invalid query packet messages

They are innocuous and can be ignored.
