Hi, I have a Rosewill wireless G PCI card being used on a Windows 7 x64 system. Every time I try to upload anything (email attachments, speedtest.net, etc.) my computer freezes, and I'm forced to restart it manually. This problem happens on both IE or Chrome (so I don't think the browser is the problem) but it goes away when I hook my system up to wired LAN. I have no idea what's wrong with it, but I'm guessing the problem lies within my wireless card settings. Anyone know how to fix it?
