Quick Wireless Help Please

[mmcd]

My wireless just went out all of the sudden.

I have a linksys router and wireless card (laptop).

When I click on the icon in the taskbar, the packets sent is increasing steadily, but no packets are being recieved.

So far I have:

Restarted the computer,

Unplugged the cable modem and router for a minute, then plugged them back in.

Taken the wireless card out and put it back in several times.

Resored my computer to last known good configuration.

Any ideas what is causing this and how I can fix it?

Thanks.
