After wasting numerous hours with this router and Linksys tech support it is going in the box and back to the store. The advertised functionality of this router simply does not work: specifically VPN connectivity is intermittent at best, DDNS works on one firmware and not the next, some wireless devices will connect, others will not. I should have known better as I have 2 dead Linksys home routers in a box somewhere. After dealing with Linksys support I know I will never buy anything from this company again; I have better things to do with my time. What amazes me is that Linksys is still selling this product. Sooner or later the Cisco folks will realize what is going on and stop this type of crap from going out the door, I just don't have time to wait.
