Using Broadcom's bcm4400 driver (which I believe is GPL), I get 10 MB/s. Kernel Version: 2.6.13 (vanilla) on a P4 I noticed when this problem was occurring, I frequently see the network interface going down and then up again in the logs. Other than swapping out the modules, I haven't done any other testing - so let me know if you need anything else. Greg Mitchell
