How do I compare TCP/IP properties?  I haven't restriced any access by MAC address.  I'm using MAC address filtering to connect to the router, but other than that I haven't changed any configuration settings that come with the DIR-655.
I'm using ARRAY SSL VPN.  I connect through my browser.  I also CISCO VPN installed that I use to connect to my client's network.  If I use CISCO VPN, IE7 works fine.  It's only when I connect using ARRAY and try to use IE7 that things go belly up with the DWA-160.
