An additional thought: Regardless of the markings, it could be a faulty cable. Try any other ethernet cables you can lay your hands on. Even if unmarked, the chances of it NOT being at least Cat 5e are negligible, unless (like me) you're a hoarder of old connectors and cables where some of them might date back to 2003 when the non-e Cat 5 standard was struck off.

Thank for the reply Mike, it's connected directly to a Ubiquiti USG-3P security gateway that control DNS etc. Then through a Ubiquiti US-16-150w switch which connects 4 x UAP-AC-LR access points, before the upgrade to Hub 4 I was on 300mb supply and getting 200+.
The patch leads are all cat5e and above.
The Ubiquiti controller has its own speed test that is showing same results as Speedtest app, the download is variable 60-120 and upload a constant 50, plan to remove the USG and go back to router mode to rule that out
I too have been having issues with speed for weeks now, changed cables etc...I have a Hub 3.0 in modem mode with a TP-Link AX6000 gaming router, haven't been able to get near my 500Mbps since August 10th... Download speeds have been really bad, down to 40 and even 8Mbps...
Hi, cat 6 cables installed, hub 4 back to router mode, rebooted hub connected direct PC was getting 200mb, after a few tests back to 100mb, connected back to unbiquit security gateway and the same, uploads still steady 50mb, have ruled our my network kit as the issue abs pretty clear it's a supply issue from, even at 200mb on reboot for a time doesn't do what is says on the tin, doing some more research it's a definite issue, don't know where to go next as customer service is poor
