Hi,
I have experienced the problem with madwifi-ng (client mode) in a work
with several wifi AP's (for ex. Mikrotik AP 2.9.17/2.9.18).
It is independent of distance and mode(a,b,g).
Download transfer rate looks normal (~10-15Mb) but the problem is with
upload speed - no more than ~3-5Mb with the same configuration parameters.
My configuration is:
{{{
