Speed tests = Awesome, Real life file downloads, complete underpants?

Any help on this before I reset Windows would be appreciated.

All speedtests show connection as expected with low ping, which is great.

Downloads however are another matter. Seem start Ok'ish then start staggering around like a drunk around town

THIS ONLY HAPPENS ON ONE PC ON THE NETWORK, others work as expected.

What I have done so far:

Modem has been replaced.
Replaced ethernet cable.
Replaced with shorter ethernet cable.
Swap tested with known working cable.
Uninstalled and deleted software for Intel 1217-V adapter.
Installed latest software for network adapter.
Uninstalled again and reinstalled.
Windows Firewall on/off - No difference

Any ideas please peeps?

Thank you.

This has been solved.

I had a HDD which failed ages ago, no longer detects as a drive but me being Lazy, never got round to disconnecting it.

I disabled the SATA port in the UEFI (Too lazy to figure out which drive it is in the case) and now all is working OK.

I suppose the duff drive drive was sending duff info to the SATA controller causing some issues?

I did also reinstall NIC drivers again and reset Windows firewall but am certain it was "removing" the duff drive which fixed it.

The problem came back...

So far, disabling "energy efficient internet" has solved the problem.
