Fedora 7 and Intel wireless 3945ABG


Im having trouble with my PRO/Wireless 3945ABG card with Fedora 7. right when i installed it i couldnt get it to activate it, and i dont know what to do. im fairly new to linux, so it would be great if someone could give me as detailed as possible tutorial on how to get the drivers working. Thanks

If the 3945 driver is installed,
you can now look at how it can be configured with WPA in Ubuntu and try something similar (it is NOT Ubuntu-specific):
https://help.ubuntu.com/community/WifiDocs/WPAHowTo

Note that you do not need to install Network Manager (it is not required) - you can just read "WPA Supplicant" paragraph, install wpa_supplicant, add corresponding lines to config files and run your network manually via for example "ifup eth0" (change "eth0" to the corresponding network interface name).

As a side note, I was able to configure WPA but not WPA2 using these instructions...

Hope Fedora users will help you with config files (where to put all WPA config settings).

I have NetworkManager install. When I setup the SSID and passphrase to work with TKIP. It still cannot connect to the AP. BTW, I'm running 64bit Fedora 7

Me too, I was unable to configure WiFi with NetworkManger - I could not understand how NM works at all, it was unpredictable So I have configured WiFi at low-level in config files (using wpa_supplicant and ifconfig/ifup or any network config files you have in your distribution).

One more link about configuring WiFi with WPA:
http://susewiki.org/index.php?title=...Wireless_Cards

First, I would recommend to try without WPA/WEP/whatever_protection, that is as a first step configure your WLAN to be public, test it and then try to configure WPA manually with wpa_supplicant.

I can connect without any encryption. I wonder if my WWAN is causing the problem.

I get the following message when trying to bring the wlan0.

Code:
wlan0: duplicate address detected!

Maybe, you have configured the same IP address for several interfaces (ethernet card and wifi) or for several computers (yours and somebody's else) ?
How does your network config look like? Check settings in /etc/sysconfig/network-scripts/ifcg-<interface> (for all your interfaces) and /etc/wpa_supplicant.conf.
