This at home, firewall is with a DLink wireless access point...no changes from initial setup a few years ago.

No apparent changes in software, including browser config. I'll set up a new user and check.

ISP is Cablevision.

I'll try Tracet and new user. Not sure haw to track port listening.

Thanks guys...keep ideas coming.

I'm rarely stumped but this one has me cold.
