post up the Downstream/Upstream/Network Logs data 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.

An alternative strategy: Disconnect your hub from mains power, and place it on a robust surface. Now get your best shoes (for example a nice pair of Goodyear-welted. Northampton made Oxfords, leather sole and good hard heel). Take one shoe in your hand, holding it by the toe cap. And then use it like a hammer and beat the carp out of the hub. Let the red mist descend, DO NOT LET UP just because of a few cracks in the casing, keep going until the whole thing is pounded to tiny fragments.
Now phone 150, and explain that your hub was constantly rebooting, you've followed advice on the forums but still got no connection, and your hub is not now responding. Of course, this might cost you £99 for a non-fault call out, but you can appeal that to arbitration with CISAS.
Don't look at me. The cat was walking on my keyboard.
