Wired or Wireless?

If this problem is limited to your wireless connection, then try a wired connection.

If the wired connection works without issue, then you may want to try checking for firmware updates for both the router and your PC's wireless adapter.

Some wireless devices just fail to get along. That Belkin seems to be a fairly recently released router. You can try contacting the manufacturer for resolution. If you continue to have problems, you may want to consider replacing the router with a different make and/or model.
