Intel 3945abg/Dell Inspiron 9400/Netgear HE102 802.11a

Postby rec9140 on Sun Mar 23, 2008 10:29 am

Are there known issues with:
ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver for Linux, 1.2.2mp.ubuntu1

Linux Mint KDE CE DVD Edition
Dell Inspiron 9400
Netgear HE102 802.11a AP

I can get the B side to work, with some occasional failures, but trying to connect again normally solves it.

Unfortunately my main network is 802.11a using Netgear HE102's.

I can see the AP in the wireless networks under KNetworkManager, but when I attempt to connect it gets to 26% and then fails every time. Manual configuration does not work either. The wifi LED on the latptop just blinks away very fastly. Most times it requires a reboot to be able to connect to 802.11b/g AP, although sometimes it will recover and allow to connect on 802.11b/g.

For a wired connection, and for at least some wireless connections right click on network manager and untick "Activate network" followed by ticking it again fixes lost connection.
To solve the problem you could try to change channel for the wireless - I had to do that to get a reliable connection for my wifes win laoptop


I have a 4965 and this procedure works. Followed by opening the Terminal/Konsole and typing the following "sudo modprobe -r iwl3945" then enter to remove the module aka driver and then "sudo modprobe iwl3945" then enter to reload it. Give the wireless 30 seconds to a minute to reconnect.
