Search in the config.mk in compat-wirless for the debug options for your devicve and activate them by editing config.mk and rebuilding compat-wireless > Twice, randomly, I've seen it going as fast as wired (accessing the > internet) so I imagine it's something than can be fixed. > I also test both speedtest.net and wget from a local mirror, so it's > not a fluctuating link.

The easiest and safest ways would be to remove the skb_complete_wifi_ack backport from include/linux/compat-3.3.h in compat-wireless.
