How to disable IPV6

If your connection to BigBlueButton repeatedly reconnects, and you connecting from home, your router might be inadvertently closing your connection.

If this is the case (especially if you are using Spectrum in the US), you can resolve this by disabling IPV6 on your computer or router.

On Windows 10, right-click on the “Network Windows 10 Network Icon / Wi-Fi Windows 10 Network Icon” icon on the bottom-right corner of your screen.  You’ll see a pop-up menu.

Open Network Settings

Disable IPV6 on your Spectrum Router

If you have the rac2v1k spectrum router, you can disable IPV6 using router’s web-based interface.
To login to the router’s web-based interface, look for the URL and login password are on the back of the router.  It’s likely and admin/admin.
Once logged in, click Advanced (at the top), then click IPV6 (left-hand side), and then under IPV6 LAN settings, choose Disable (as show below).
