Same scenario here,,,,,, 40 down 2 up on coax. Just changed to 30 down 30 up, on fibre. For relatively the same price it was a no brainer. The small upload was killing me in terms of choking throughput when downloading and impeding RDP to work etc etc. or any other streaming or gaming caused interference.
Capped on coax, not on fibre another plus. On the con side, 1 year contract on fibre, can quit anytime on coax.
Have to keep coax lite until migrate email addresses........
the only difficulty initially was that they provided a modem router with wifi and I just needed a modem. managed however (on my own as not supported) to configure the router into passthrough mode so my own router gets the WANIP.--
