wlan0 fails to activate


When I try to use my wireless on linux, I get an error message stating that wlan0 fails to activate due to an error 0686. This happens whether I try to activate manually or set it to activate on start-up. Here is the complete error message:

Now, I am running RedHat 5.4 in a dual boot with Windows XP. (It works fine in Windows.) I am using an Intel PRO/Wireless 3945ABG adapter. Furthermore, this has worked before. Has anybody had a similar problem? Is it just a matter of entering the password? (If so, how do I enter the password without first activating the network adapter?)

It's possible that your wireless may be identified as eth1, rather than as wlan0.

Please post the output of ifconfig and of lspic, being sure to surround it with "code" tags, which become available when you click the "Go Advanced" button at the bottom of the quick reply window.

Since you are using RHEL, you could call them for support if you purchased a license that provides support.
