How do I get wireless working from the Debian shell?
Here is what worked for me on a C700:
cru cardctl scheme CardResume cru cardclt scheme qpewlanX # X is a number of 0 or more and corresponds to the numer of the WLAN connection defined in the ["QTopia"] Network GUI
To shut down the wireless connection, do the following:
cru cardctl scheme CardSuspend
You can also turn the network on and off with these commands:
cru ifconfig eth0 up cru ifconfig eth0 down
