What's your signal strength? If it's high and you're getting dropped, your router is rebooting. This is a problem some D-Link models had (and likely other brands as well, since even with these problems D-Link make the only decent routers); upgrade the firmware and you'll be fine. In fact, upgrade the firmware regardless.
If it's low, move the damn router or don't try accessing it from down the street.
