Thanks for the reply.

a) tried the router reboot - no luck. I cant physically access the router to get to the button at the back. I have considered a router fimware upgrade, but am concerned things may go from bad to worse!

b) the router is telling me it has internet access. I will unlug the tivo connection to see if that helps. As I mentioned before, I casn ping external IP addresses, the problem is I cant get web page access through the router.

c) the windows firewall is disabled.

Any other thoughts/comments?
