"I was looking forward to my first normal morning online in a while today, but no such luck. My connection keeps dropping and my DSL router's ready light keeps blinking. I picked up the phone and heard the familiar siren sound that phone techs use to troubleshoot the line."
I had a similar experience with my DSL: intermittent drop-offs, slowdowns, blinking ready light, often loss of synch. All symptoms worse during/after rain. Turned out it was several arced shorts at the box where the line came into my house, not at the pole. After two phoners and two tech visits, one smart guy checked the box and found/fixed the shorts. DSL service has been great since.
