Hi Tom, I use a 3com 3C589D (10Mbps) on my ancient Dell Inspiron 7000 and it works fine. I also have a 3com 3C589C which also works but again at 10Mbps at best. I find this is fast enough for my purposes on the laptop. I don't need the 3C589C so if you want it just let me know and I'll send it along.
Regards, Brian
the 3c575B is certinaly mentioned in the source, however I have used 3c589 (10 Mbps) and Netgear FA411 and FA511 (100Mbps) successfully if you have any of those.
