Ok, I've got an Atheros card in my machine, running the latest version of ON, but it also occurs in b90 and B91 too.
I'm experiencing uneven traffic flow; when downloading off dlc.sun.com, it slows down to 9KB/s, then it suddenly speeds up to 120KB/s. The signal is 'good' (according to dladm), and due to the poor reliability of nwam, I've set it up manually. Is there anything I maybe missing? Matthew
