I couldn't find any posts about this, so I'm sorry if someone already posted this.

I just loaded Windows 7 64 RTM onto my computer that has an ASUS M2N SLI deluxe motherboard. Every so often, my computer will 'lose' the gateway address, where, when I do an ipconfig it shows no gateway. Resetting the adapter fixes the problem, but I'm not sure how to permanently resolve it.

I've even set the values manually to no effect.

I've even installed the Nvidia 64-bit drivers but it still happens. Everything else is working fine.

About the only other thing I could think of would be Norton 360...any ideas?
