Tx

2.4 ghz will not be the problem. What is the CPU and what service are you taking?

JMaples. Did you run TCP optimizer? When you load into safe mode windows runs it’s standard registry file. Exactly like a fresh install. You have demonstrated that your speed is fixed when you do so.

I really can’t help you anymore unless you just want to wipe your system. If you do make a clean USB install image as using the standard recovery in windows settings still doesn’t do a true clean install.

Tx. I tried but it actually reduced the speed and I had to restore the settings

If he wipes and starts from scratch the "problem" will be resolved, without need for any TCP optimiser. The precise cause is unclear, although given connection is fine, hardware is capable, W10 updates unlikely (or there'd be widespread issues)....then suspicions would point to his security s/w

and I thought the op was talking to the suppliers of this software. My experience is that this way madness lies, it is simpler to abandon this third party junk and use other mitigations, that also work on mobile devices.

Agreed. The poor chap spent 1.5 hours on the phone with Zen...I'm a bit lost for what his thought process is here. You can fully uninstall an app and reboot in a a few minutes. Test again. No improvement. Move to the next suspect...

If all else fails, back the thing up and clean it off. You should be done in the same time (or less) as the friendly chat with Zen...let alone the other s/w vendors.

The only thing different that would occur during safe mode is the NIC using a default windows driver. I wonder if he deleted the NIC and the driver and allowed windows to reinstall the latest approved version that might help?

(Just to clarify this may of already occurred I haven’t gone back through the entire conversation)

Its a Microsoft laptop, does it even have any non-MS drivers?!

Yeah they do. Mostly intel but I do believe in the older versions they used another supplier.

I jumped on board with the Surface Pro 3 myself. They moved away from the semi-version of windows if I remember correctly. Was years ago so I can't quite remember why I wouldn't have the Pro 2 but could be something else.

Just worth a shot really. I hate reinstalling everything personally so I avoid it.

If you see anothing like roll back in the device settings give it a try anyway...

I have a 1GB USB NIC for my Surface Pro 7.

I only use wi_fi but I am going to test how fast it performs on my connection using the adapted. I will provide feedback shortly.

It's as close of a comparision test as I can do.
