my computer`s wireless network doesnt seem to work, itel(R)pro/wireless LAN 2100 3A mini pci adapter.?

the above is the problem. Can any advise of on how to fix it as im sitting next too the router in the living room with ethenet. Would prefer my wireless connection back.

If the computer can’t see the signal from that distance, reinstall the driver. If that doesn’t help the adapter may be bad. (You didn’t accidentally remove the antenna from the adapter and forget to put it back?)
