MP 1,1-5,1 Internet upload speed slow on 5,1

[MikeymikeT5]

Hello...

I'm wondering if anyone can shed any light on the issues I'm having?

My MacPro 5,1 has suddenly become incredibly slow at uploading to Youtube/Vimeo. It should be running 20Mbps upload speeds, but is actually running about 0.91Mbps, which is driving me crazy. Yesterday, I did a PRAM reset, and SMC. After restarting, it was back up at 20 again, but last night it got slow again, and nothing I do seems to recover the speed back to what it should be. It's the same issue on either Ethernet, or Wifi. My MBP laptop and phones are seeing the 20Mbps uploads though.
I've also tried deleting the internet connection in the preferences panel, and adding a new connection.

I meant to add, I'm running Mojave 10.14.6

Any ideas anyone?

Thank you.

Mike

Try reset the whole network.

e.g. Power down all computer, router, cable modem. Remove power from them, wait for 5 mins, then turn them back on again. Sometimes, it may be the router's problem, not necessary the computer's issue.
