ADSL vs Anger Management

I’ve had my broadband drop twice today, once when I was about to post! Until a week ago any dropout was unusual, and now I’m getting them at least once at day, 30 minutes to 2 hours at a time.
As I use the Internet to earn a living this is really beginning to bug me. Since I tested or replaced every piece of wire and hardware I use, I’m now convinced it’s either a piece of hardware or some work that’s going on at the exchange which is taking away my service.
Perhaps I shouldn’t of previously mentioned my concern about Pipex and Tiscali…it’s now coming back to haunt me. I don’t want to go cable, but I can’t go on with an occasional service!
