Take a look at this site to see if these settings helpThanks. I've got two laptops both on wifi. Just tested both, ~84 Mbps download, 18 Upload. I also did so on bing.com (they have a speedtest apparently) and that only gave me 27 Mbps download for some reason.
Are you able to tell me how you got the vimeo link via inspect element? (on which browser).
Edit - did another bing speedtest. The 27 Mbps I said earlier was on the slower laptop. the faster one gives me 84 Mbps, which matches speedtest.com
