Okay, so I've just bought a Netgear modem/router and three WG311v3 PCI Adapter cards. I installed one fine into my computer, then I did same process on my dad's computer and thats when things went screwy. After I installed drivers then rebooted and inserted card as per the instructions the computer would get to the windows desktop or not even that far and just freeze. It's a fairly old computer Intel Celeron 900mhz, 512mb ram but I'm pretty sure that it should still handle the card. I've found some other people having problems with it and some got it to work after disabling DMA or other devices. Not tried that yet, but could it be a problem with the BIOS seeing it's from 2001?
