Ok, that was clear to me. I don't know where you read that i want my own RSSI? That would just make no sense. > Not all drivers report RSSI in adhoc mode at this time. =C2=A0But eve= n if > they did, they could only report RSSI when they receive a beacon or > traffic from some other node in the adhoc network, and that's pretty > useless because it doesn't give you a general quality of the "network= ", > it gives you a specific quality of the radio path between two points = in > the network. Maybe i should point out, what i am trying to do :) I need the RSSI values for distance measurements between the nodes. So what i need is not a "quality value" for the whole network, but the recieved mW from every reachable point in the network. So i think the RSSI value for every network node (if i can print them out seperatly) should do the job.
