I am on a slow rural dial-up connection. However, recently I began to notice an alarming drop in my already-abysmal connection speeds and download bandwidth test results from pcpitstop. On really bad days, the connection might say 21 kbps, but download bandwidth tests out at 3 or 4 kbps. On a really good day, I might get 26 or even 44 connect speed, with DL speeds of about 18.

At around the same time, I began intermittently getting those error messages of "Connected phone line is not compatible with this modem. Only analog phone lines are supported."

I thought the problem was with my phone line. However, today I plugged my son's laptop computer into the exact same phone line that my desktop is plugged into, and it is getting connect speeds of 44 -46, and DL tests at a low of 18 up to a high of 39!
