Just go to Start -> Control Panel -> Network Connections and doubleclick on your Network Connections' icon.
Check out the "Support" tab, if "Address Type" says "Assigned by DHCP" then you're using your router's DHCP Server ( perhaps the DHCP IP Lease is 1 hour, so it might be releasing the IP every hour ).

If you're using DHCP, try setting the IPs manually, and check if your issue insists.
