What Hub model do you have (printed on the base sticker) - however if ethernet connections are dropping too - then try this....
First job, set up a free “BQM” to continually monitor the state of your connection and record any dropouts. It does it 24/7/365 and it keeps a visual record of all your network disconnections, useful data to have in discussions with VM.
Then check that 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. 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 at top right (SH2’s) or the text at bottom-middle - of first page up (Hub3) and then copy/paste 3 FULL sets of data onto here – from the Downstream, Upstream, & Network logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you.
