Okay, the AT&T Repairman was just here. Apparently, the Saturday installer inadvertently broke my phone line cable. After a few minutes, the repair was done. My DSL is back, but still 25% slower.
I also heard that there is a new U-verse Internet only service. The U-verse signal is 10X faster than my DSL. According to he, the landline and U-verse can run on the same pair of wires.
