Resolved! Zoom (or Team) slows down internet speed by 30 times
Oct. 11, 2023 Seeing more responses on the issue, I updated my original message to make it more useful. Problem: On my Windows 11 laptop (Lenovo ThinkPad, E495, ethernet wired connection), when I start Zoom (even without signing in, same with Microsoft Team), the internet speed test shows a 30-times drop, from 450 Mbps to ~10 Mbps. Temporary remedy: After your Zoom session, QUIT Zoom (or Team) COMPLETELY so your internet speed is back to normal. You make sure this by clicking the "Show hidden icons" arrow at the bottom-right of your screen to see all the applications running and exit Zoom if it is still there. Attempted fix. It worked briefly for an earlier version of Zoom, but does not work anymore (after Zoom version evolution) as of Oct. 11, 2023 : 1.) Search for the "Control Panel" and open this up. 2.) In the window that comes up, click on the "Network and Internet" link 3.) In there, there will be a link that says "Internet Options", click on that to get another pop-up window 4.) In that pop-up window, towards the top, look for the tab that says "Advanced" and click on that 5.) Scroll to the bottom of that window, look for where it lists "Use TLS", check "Use TLS 1.3", and uncheck "Use TLS 1.2". Also tried Google Meet. Although the network speed test shows no issue, all applications become slow and lagging. It is worse than Zoom -- even the slowdown-plagued version.
