I've had pretty good service with Comcast (and it's variations of owners over the years), but in the last couple of months, I've had service go out on a somewhat regular basis. This time, my service has gone out nightly for the last 4 nights in a row starting at about 8PM. And it stays out for the night.
When I call the (no)help line, they say all they can do is send somebody out next Friday. Of course, it works fine during the day time. There's apparently nothing they can (or are willing to) do to fix it. If it was a one time thing I could accept that - I have throughout the years - once in a while there are problems. But when it becomes regular and you can't find anybody who is willing to help it's time to look for an alternative.
That's why I started looking for DSL.
