ssh disconnections - Network error: Software caused connection abort

[thepugman]

Router: ZTE Model: MC888A  (placed 2 feet from laptop) - 5G tower is 500 meters away
Speed Test: 190-250Mbps Download / 30 Mbps Upload  /  Latency: Unloaded: 30, Loaded: 60
pinging google.com no packet loss during ssh disconnection

Hi, I had Starlink (and still do) and get no connection drop outs using ssh, however, with my 5g Broadband I am getting consistent connection dropouts using ssh and struggling to figure out why.
As above, no packet loss during timeout of ssh

Wondered if anyone had similar issues and managed to figure this one out?

I've tried changing 2.4Ghz and 5Ghz frequency from Auto to a dedicated channel - no difference
Also checked if there is a firmware update for the router - there isn't.
Not tried changing network selection from Automatic (5G&4G (preferred)) as it says "The setting can only be changed when the modem is disconnected" - which makes no sense to me

Thanks in advance

So I tried connecting on a neighbours 5g internet too - same issue occurs, so it's not my hardware causing this. Three customer services are not technical enough to deal with this issue either, therefore, cancelled the contract.
