SBC Yahoo DSL - Inconsistent Service/Suspicious Policy

I have had SBC Yahoo DSL for about 2 years without any problems until recently. Within the last 2 weeks service has been dropping in and out, mostly out and has been getting progressively worse. I initially called SBC 3 days ago and got the automated voice at customer service. The voice asked me if I was calling from the same number as the DSL, which I was. It put me on hold while it checked on the status/activity of my account. As soon as that happened the light on my modem/router went from red (not connected) to green (connected) and remained on green. I hung up thinking the problem was solved. It remained green most of the day but then dropped out. I called again and the exact same thing happened: I reached automated customer service, it checked on my account, the green light came back on, and I hung up.

The next day the red light was back on and remained red until I called them the following day. Once again I reached automated customer service, it checked on my account, the green light came back on, however, this time I waited to speak with a human being. The human customer service rep insisted that I must be having interference problems with some machinery in my area. I explained that the DSL reconnects when I call customer service, so it must be something that they are in control of. But he insisted it was interference and told me to move my modem/router to another location and try that for 3 days.

I decided not to move the modem/router to see what happens. So far, after 2 days it has been working perfectly.

I am suspicious that SBC Yahoo (and now AT&T) is displacing broadband width from old time customers and providing it to new customers. Perhaps their infrastructure is overloaded. It appears that they wait until customers complain before turning their service back on.

Has anyone else experienced anything similar?

Sincerely,
