If the problem is the Netgear router, I'm fine with replacing it. Since the ATA is a Linksys device I was thinking of getting a Linksys router. Any suggestions would be appreciated.
One really quick thing you could do is connect the device directly to your modem. Be sure to reboot the modem and then the device too.

Obviously you can't leave it like that forever, but by doing this you can test it to see if your issue goes away and confirm that it's the router.
