I am having difficulties in the recent days - the connection drops off (the modem cannot be reached from the comcast facility); it is down for a good 45 minutes to 1 hour. The connection restores itself.
Comcast replaced my modem earlier this year and a few days ago as well ( so two new modems in less than 6 months ). Every time I call them they confirm that the connection is having issues - since they cannot reach the modem. By the time the technician gets out to my house, the connection is fine and the tech walks away saying everything is find and dandy.
I work out of my house and hence my paycheck is tied to the availability of the internet :(
If you are / were having similar issues with comcast, please share what you did to get them fixed...
On another note, the DSL users out there - has your internet connection been stable? If you had issues, was the service quick ?
