[nflug] DSL

Fri Apr 28 14:54:21 EDT 2006

When I was setting up my Sunrocket VoIP box, telling it to use PPPoE (as 
SR tech support told me to do) cost me about a week of no service.  When 
I finally got a tech who told me to turn it off in the VoIP box, then 
everything started working.  How does that relate to what you just said?
