I had two WRV200 fail on me during firmware upgrade. Both started to upgrade and 1/2 way through failed when i got page could not be displayed and now nothing happens. No IP address is given even though lights turn green etc. This occured on two different network. Also I have it working in 2 other office and its very flakey, it locks up on the admin console so you can't access the admin page ( http://192.168.1.1) unless I reboot the router. I think this is the worst quality VPN router Linksys produces. I got VPN tunnel to work and its easy to setup but its not stable.
