ipw3945 not connecting to Access Point


Hi all,

This is my first attempt at setting up a wireless connection on my toshiba tecra a7 using a ipw3945 card. I have read many posts and have got this far, but I am not sure why I am not able to connect to the access point.

I cannot see anything in /var/log/messages, but I think the problem might be in my wpa settings. I would appreciate any help to get this problem resolved. Might also help to know that I have an other laptop (running windows XP with the network access set to 'access point preferred')that is currently connected to my AP (D-link 624) and its settings are;

Security: WPA using PSK .... using channel 6.

Below are my settings.

Hi all,

I finally go this going!!!.... all the above steps seemed to have helped to connect to the AP. The NetworkManager was the key for me to get this going!!! Here what I did...

Code:
# system-config-services
and enabled the NetworkManager and NetworkManagerDispatcher, the "File" and save... once back at the prompt...
Code:
#service NetworkManager start
Then from the desktop access the network manager icon from the top right hand corner and select the wireless network you need to access, ofcourse configure any settings i.e. type of encryption and keys and thats it!!!
