My internet connection is flaky. I switched to Comcast in February. Since that time, I never know if my connection is going to last for 5 minutes or 5 hours. I've had my computer checked out, bought a new modem *and* a new router. I spent 1 hour on the phone with two Comcast technicians. After working with them the problem was solved. For one day. Now it's just as flaky as before.

Has anyone experienced this? If so, how did you solve the problem?
