If you're in the market for a network card that is pretty hassle free and just works then this NIC maybe worth a look at.
It comes with the usual bells and whistles (WakeOnLan, auto sensing, et al) But the driver support is pretty decent.
However if you've never installed anything hardware wise for PC before then the supplied manual on how to do it will be ghastly,
Since it lacks diagrams and the like, I recommend looking at web guides on PC selfcare/upgrade before attempting it, if you're not sure how to go about it.
That said, installation is painless once the hardware side of it is done, I installed onto a PC running Windows XP Pro, which didn't automatically install drivers for it sadly, but all you have to do is pop the CD in and click 'Install Drivers' and restart, and it'll be up and running, you may get lucky and have to do zilch like the reviewer above!
Note: If you get Windows telling you its found an Ethernet Controller, thats wrong, go ahead and install the provided drivers.
I've also tested this NIC with Linux (2.4.24) with the supplied drivers and it works well (and you get the source to the drivers so you don't need to worry about binary only issues)
Amazon don't tell you what drivers it comes with, so here you go:
--Windows 95/95OSR2, 98/98SE/Me,2000/XP.
--Novell NetWare 3.x, 4.x,5.x,6.x and ODI.DOS.
--Microsoft Windows NT3.51, NT4.0.
--Microsoft Windows for Workgroups 3.11.
--Microsoft Client for DOS.
--IBM LAN Support Program v1.3x.
--NDIS 2.x, 3.x, 4.x, 5.x Driver.
Overall its easy to install and start using, but the provided documentation (hard copy, plus PDF) for installation is dire, if you need to read it! still, five stars.
