Windows 7 Fix For Losing Connection to the Internet

Like many PC users and avid gamers, last week I purchased and installed Windows 7. This new operating system from Microsoft was supposed to have fixed many of the stability problems encountered with Vista.
Within minutes of upgrading my Vista 64-bit version of Windows to Windows 7, I started losing my connection to the Internet approximately 30-60 minutes. For no apparent reason, my computer which was attached to the Internet via a D-Link Gamerlounge router would drop it’s connection while the other computer running Windows XP hooked up to the very same router enjoyed uninterrupted Internet service.
I would get the following message when I hovered over the Internet/Network: the default gateway is not available. Each time I would right click on the connection icon and select the “Troubleshoot Options” it would eventually repair the problem and reconnect to the Internet.
