I'm testing driver from -wireless testing, cca 2.6.26-rc7. It seems to work (up to 802.11n speeds -- I've seen iwconfig claiming 121 MB/sec), but disconnects rather quickly when under load: telnet 192.168.1.3 chargen > /dev/null The machine is powerpc mpc5200b board, with OHCI driver -- it is not capable of USB2.0 speeds. Any ideas?
