Ok you're the second person who mentioned this IPv6 thing.   The
router is an AT&T DSL 2701g model.

I ended up downloading an IPv6 clickable add-on to Firefox that
toggles it on and off.  It seems to be doing a better.  More of a band
aid but it will do ... for now.  Less intrusive that way, less to get
into trouble too. Thanks.

Curious, do all browsers in linux default to ipv6 in linux?  Otherwise I'll
look at others.
