Outage 3 nights in a row

Out internet has gone down around 6-7 pm every evening for 3 nights. Comes back up around 9-10 am.

Can connect to every router but none have internet.

Neighbors are not having same problems.

Comcast chat told me the first night it was unplanned maintenance.

But it doesn’t seem like they know. All they offer to do is come out. Seems doubtful it’s a problem with our equipment.
