Full fibre 900 but not even half the speeds over Ethernet.

Re: Full fibre 900 but not even half the speeds over Ethernet.

@bobpullen im willing to try anything. Will take my laptop over to my relatives house to test wired in their network, in the meantime, I have tried a different laptop over wired and now seeing between 400- 500mb wired. I'm perplexed.

Re: Full fibre 900 but not even half the speeds over Ethernet.

Do these laptops have SSD drives and how recent are they? I mentioned it previously, but client hardware specs also need to be taken into account. Example: a 5400RPM spinning hard drive might have a maximum write speed of 75MB/s, which equates to 600mbps i.e. two thirds of the speed of a 900mbps broadband connection, and that's assuming no overheads/contention affecting the disk I/O.

If the laptop simply cannot write data to its storage medium quickly enough, then it's not going to be able to saturate a 900mbps Internet connection. Likewise if it doesn't have enough available free memory or a decent enough CPU/processor.

I wonder if it's worth looking at the Task Manager (assuming Windows) the next time you run a wired speedtest?

@bobpullen 

Inspection of machine stats is a good tool to add to FTTP speed concerns diagnostics.

Re: Full fibre 900 but not even half the speeds over Ethernet.

Hi @bobpullen bit of an update. The device is more than capable of 1gbps over Ethernet, SSD i5 less than a year old laptop. Now when I test via mlabs measurement I'm seeing around 700mbps over Ethernet, other sites such as fast.com and speed test.net barely 500mbps. The btw speed test doesn't even register above 400mbps!?

The most consitent speedtest for the high speed connections is the Ookla one , preferably the cli version

Re: Full fibre 900 but not even half the speeds over Ethernet.

@Karamelk - looks like specs should be OK then. Is it a corporate laptop, and if so is it configured to use any VPN/corproate intranet connections? That's another potential bottleneck.

I haven't tried regrading your line yet because I'm becoming less confident that it's going to help, particularly as you've now seen ~700mbps. I think the real litmus test will be what either laptop can do at the other location (make sure to use the same cables etc.)
