my brother's DSL (bellsouth) died after a neighbourhood power outage. The outage didn't last long (a few minutes), but since then (7 days ago), the dsl hasn't worked. It gives us authentication errors or failure to locate PPP host.

Telephone works with no hisses/noises/abnormalities. Bellsouth is being uncooperative--they're turning us in circles to avoid an on-location diagnostic.

Anyone had this happen to them before? What went down? Thanks.
