I'm new to the forums. We recently signed up with Comcast 50 Mbps. Had some issues with the service for the first couple weeks on and off. Finally it went out on Friday, so we had a tech come over on Saturday.
Things are much better and so far we're not getting any modem reboots. But fortunately
this speed test site has been helpful for figuring that we're getting really slow speeds during the peak time. It averages around 4 Mbps -10 Mbps during the times between 5:30pm - 11:00pm.
I've spoken to one of the local officials in charge to get another tech to come out on Wednesday to hopfully figure out what's going on.
