As you are getting disconnects on wired equipment, try these steps as a starter.
First, set up a free “BQM” to continually monitor the state of your connection and any dropouts. It does it 24/7/365 and it keeps a visual record of all your network disconnections.
https://www.thinkbroadband.com/broadband/monitoring/qualityCheck all your coax connections are in nice and "finger" tight at the Hub and wall box and at any splitters/attenuators/etc and that the internal wiring is ok with no kinking or chaffing (rabbit chews!). Also check that all looks good with the outside cabling and wall box.
If that’s all good.... post up your Hub/network connection details and someone will check to see if there is a problem there. In your browser’s URL box type in
http://192.168.0.1 (or
http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before] click on the “router status” icon/text at bottom middle of first page up and then copy/paste 3 FULL sets of data onto here - the downstream, upstream, & network logs. Don't worry too much about the formatting it can be easily read & don’t include personal data or MAC addresses - blank them out.
