I have mixed reviews on the Linksys NC100 NIC. I've used them in a couple of Win98 boxes without any problem. But I couldn't get Mandrake Linux to recognize one. And I have one in a W2K Workstation box that requires me to load IPX/SPX/Netbios protocol as well as TCP/IP to read many machines on my network and it takes a long time to make up its mind that it can recognize the other machines. And it flat out won't recognize one other computer, no matter what, though that Win98 machine has no problem accessing the W2K box.
Worse yet, I had an Asus P3W motherboard that wouldn't even POST about 1 time in 4 when I had this card installed. I took the whole computer to the vendor from whom I'd purchased the mobo and his techie systematically tried swapping out my RAM, power supply & CPU, but had the same symptoms. Then he pulled the Linksys NIC. I protested that it couldn't be the NIC, that it had worked in two other machines, but the computer booted every single time without the NIC. He put in a Netgear FA310TX and the machine booted 45 times in a row. We replaced the Linksys, it booted twice and then hung, booted three times and hung. Then it booted another 30 straight times with the Netgear card. I went out an popped $20 for the Netgear card and never had the problem again. The tech said that the Linksys cards had really lousy quality control and could even damage the rest of your system, so they wouldn't even sell them. It wasn't worth their time to troubleshoot them. If I weren't such a cheapskate I'd go to Fry's and shell out $180 for the 10-pack of Netgear FA310TXs and upgrade all my machines. You might be lucky and never have a problem with a Linksys card, but then again, they can be a real PITA. I wouldn't recommend this NIC.
