Hi, i have a problem using NDISWrapper 1.1. in fact its not a problem, just a question.
i am using RedHat EL AS v.4
i've installed NDIS, wrote ESSID, KEY and got link with my AP(when used iwconfig it listed MAC of AP).
So here is my question: what to do next? i make "ifconfig wlan0 up" but then i cant ping my AP(192.168.0.50) it writes that host is not reachable.
Then i though that i am just to create a new network connection, but i couldnt find my wlan0 in the list
May be i am to cahnge IP?
System: kernel 2.6.9-5EL;
D-Link G650+
Please suggest anything
Thanks

P.S Sorry for my English
