I'm not sure if you mean the rt2500 drivers as in the debian packages. Also I have a rt73 so what follows may not apply. I think the rt* series have been included in the kernel as of 2.6.24. Prior to 2.6.24 I used the enhanced legacy drivers from serialmonkey and have gone back to them in preference to the in-kernel package modules as they performed much better, between 2 and 8 times the throughput. You will need the linux-headers package to build them and to rmmod the in-kernel modules before modprobe 'ing the legacy driver. The legacy module name in my case is rt73, the kernel ones are rt73pci or rt73usb. -- rob http://www.worldcommunitygrid.org/team/viewTeamInfo.do?teamId=82BS4ZCMFR1 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
