Something screwy's going on with my wireless modem and ethernet card, and at this point I'm not exactly sure what the problem is. I do have a feeling however that my ethernet card is dead. My wireless modem has a usb slot, and I know you can use usb instead of a network adapter, but what all does it involve? I have the correct usb cable, but I know it's not as easy as just hooking it up. Wouldn't I need software for the modem or something along that line?
