I'm using Mandrake 10.0 Community on a Compaq 2135us. I have an internal Dell TrueMobile 1300 802.11 b/g card, and a MS mn-720 pcmcia. Both cards use the same broadcom driver. I have the same problem with both cards. To keep things simple I removed the internal Dell, and would like to use the mn-720 ( better range). I have got ndiswrapper to install with no problems, the card show's up/lights up and is working with no problem. However it will not connect to the internet through MCC. It shows sent/received bytes when trying to connect, then says "Not Connected". The card will show it works/connects when the laptop is hardwired with eth0 pluged in. The router shows the card is getting a ip with dhcp. When I click on a link, Konqueror shows "An error occurred while loading" "Unknown host"
I have disabled MAC filter, WEP, WPA, everything that will keep this as simple as possible. Until I get wlan0 working then will deal with those problems later.

iwconfig wlan0 shows

I have tried linuxant also and still no help. All other information I can find on the internet will not help, or mention anything like this problem.
Any help will be greatly appreciated

Sorry for the wast of time, it is the simple little thing that get overlooked. The first thing I should of checked was the last. It was the firewall blocking this device.
NOW I WILL NEVER GO BACK TO WINDOWS.
