For the last few days internet service keeps dropping, then comes back, then drops again. It is significantly worse at night.

@XfinityMikeB​ Its dropping randomly. The worst was 2 nights ago, it was the middle of the night, nobody was doing anything and it dropped multiple times for multiple hours in total. Tonight, it just dropped 3 times over a 30-minute period, for multiple minutes at a time, we were watching streaming TV and doing email, the same things we have done successfully for 18 months. It's just in the last 4 or 5 days that the service has started failing. Our neighbors are reporting similar.

And one other thing to note. It's the cable modem that is losing internet connectivity, so 100% of devices connected either wired or wireless to the router/switch lose internet connectivity.

Can you confirm the equipment cables are plugged in and the coaxial cable has finger-tight connections to both the wall outlet and your equipment? Do you notice any damage or bends/kinks in the coax line leading up to the modem? Is there a splitter connected by chance?
