hi,
i have a broadcom BCM4306. i have just installed the drivers by the help of ndiswrapper but i cant activate the device from KnetworkManager.The ESSID appears i can see the access point but when i try to connect, exactly at %28 of the process when it starts configuring the device the window closes and it just fails.I already entered my IP,subnet mask and default gateway from YAST wireless network configuration setup but still cant connect from Knetworkmanager. I can only access the network whenever i enter the IP and subnet mask manually from root shell(ifconfig wlan0 ip_addres subnet_mask). In that case still Knetworkmanager cant realize its connected so i cant use instant messaging tools this time. What am i suppose to do in order to get connection on Network Manager?

You are making things difficult for yourself (and for us) by mixing all these tools (yast tool + NM + terminal).

First things first: try to bring the connection up on the command line using iwconfig, like this:

If this works, ie, the interface wireless access point MAC is displayed using "iwconfig" of "ifconfig", then try to get an IP number:

If you get are assigned an IP number, you should now have a internet connection.

After that, you can start playing with NetworkManager or other tools to try to automate this process, but only after the above works.
