Broadband connection keeps dropping
Hi
I'm experiencing constant drops of internet connection recently. This started about 6 weeks ago when the router (Hub 3) at the time started to disconnect maybe once a day. I called tech support who sent a tech out a few days later, the tech thought it would be the router and installed the Hub 5. This made matters worse and within 24 hours I had 58 disconnections with the hub flashing red and then when quickly auto connect again. I called the tech team again who said a repull would need to be done and the next appointment would in two weeks, repull was done and still the same issue, they had booked a tech for today but they cancelled due to short staff and now having to wait until Saturday for them.
Please see my stats below, any help would be greatly appreciated.

Bit of a dogs breakfast - need to start from a clean sheet - can you do this then post them again...
____________________________
Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, Do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Disconnect all the connections and reconnect to be sure. Ensure there are no “unterminated cable loose ends. Also check that the internal wiring is ok with no kinking, chaffing or dog chews etc.
Also, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then, switch the Hub back on and leave ~5 minutes When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.
Also check the Upstream QAM’s are all at 64 - if they are still dropping (to 32/16) then see message 3 here…
