Have you done speed tests on a pc connected directly to the ONT? That should be your first port of call if not already done. If you’re seeing 300 Mbps consistently from the ONT directly then nothing wrong at Zen’s end.

I can try it if l can find a long enough cable. However ideally it have to have a basic OS install: no AV/Anti Malware so that nothing could interfere with data throughput. Such a set up doesn't represent how an internet connection is typically used. Zen don't say 'Average 300Mbps as long as your device is connected directly to the ONT'. They provide a router that sits between the ONT and my systems so l think it would be reasonable expectation to achieve their stated speeds with the hardware they supply.

However my curiosity has got the better of me and, as l said, if l can find a long enough cable then I'll try it. I assume It's a matter of setting my PC's IP address with my Zen supplied static IP/Gateway and use their DNS servers?

I understand where you’re coming from but technically Zen are supplying you with 300 Mbps at the ONT port so you need to go back to basics and check there first. You could potentially be wasting time trying to troubleshoot other stuff if you’re not getting 300 Mbps at all from the ONT. It’s very easy to setup a PPPoE connection on any Windoze machine, no need to disable AV or setup a static IP. And if you do find you’re getting 300+ Mbps at the ONT, then most half decent routers should easily cope with 300/50 wired speeds - including most Fritzbox models.
