Anyone else getting buffering when using ipv6?
I traced my buffering issues down to the IPv6 standard. With IPv6 enabled in the Windows network adapter configuration, my YouTube loading speed are capped at 10Mbps, which leads to buffering in 1440p and 4K videos. As soon as I disable IPv6 and use only IPv4, my speeds go to >100Mbps.
I'm on a 1000 down, 50 up connection, and using a Ryzen 5600, Windows 10 system connected to a AVM Fritzbox 6591 cable modem/router via Ethernet.
What I'd like to figure out is what is the cause of the issue. Is this a YouTube issue, a ISP issue, or a issue on my end (i.e. router, cable, Windows, browser, etc.). Does anyone have similar issues with IPv6? Is there a way to keep IPv6 enabled but still load YouTube faster than 10Mbps?
