When I use UDP traffic over an 802.11g connection, the rcstat file is not updated. Not sure if the rate control algoritmh works during the process. If I use TCP traffic, rcstat is updated and statistics/rate change accordingly. Is this the correct behaviour of minstrel RC? I went through documentation regarding MRR and retransmission bounds but wasn't able to figure it out. Any one noticed something similar? Thanks in advance, Antonis
