I've my 2.31 kernel running (from archlinux repositories) and compat-wireless 2009-11-06 and now not even with pid i get it working good. It goes to the max rate available. >>From the distance that I'm from the AP i have to limit the rate to 11Mbps I'll compile wireless testing and i'll post the statistics, or if someone tell the information they need to debug it i'll post it. -- Martín Ernesto Barreyro Analista Universitario en Redes de Datos.
