I started using kernel 2.0 and that card worked very nice. I could even play quake while sending out data at 10Mbit/s, I didn't even notice that the transfer had started. Then I upgraded to kernel 2.2 and I was no longer able to play quake while tranmitting at 10Mbit/s with the exact same hardware. Sometimes I could hardly even play mp3's :( Then a friend of mine that also upgraded to kernel 2.2 began complaining that his machine also became extremely slow and unresponsive while transitting at 10Mbit/s, in fact that machine was even slower than mine during the transfers and his cpu was a bit faster than mine (also AMD). Then I upgraded that machine to pIII 700 and even that machine slows to a crawl while transmitting with that bloody ISA NE2K. It's the same thing in kernel 2.4 too. These days I simply don't use that card anymore... So something seems to have taken a wrong turn between 2.0 and 2.2 I don't think this is a problem intruduced in 2.4. /Martin Never argue with an idiot.
