Yes, I too have had DSL since 2000 and try to get everything I can off forums and web sites. But we're on some sort of remote office link. And there was a router/repeater in the RO that occasionally wigged out. Unfortunately this meant my local copper DSL line tested out fine, but I still had no connectivity. So, there I am with an 800 number, and total dread, to report the outage.
This situation completely befuddles all first line VZ support staff and they always forced me through an idiotic flow chart of browser configuration and PC connection settings before escalating. Once escalated the problem was usually fixed in 24 hours.
One time I actually signed up for premium support to bypass the IE setup insanity. Then I had to call back and remind them to drop the premium support charge, since the problem was in their equipment, not mine.
