Xbox One X dropping IPv6 Connection.

Do you know if you ISP supports IPv6? Your router could be tunneling your IPv4 connection to an IPv6 which basically means it is sending IPv6 packets through an IPv4 connection to communicate with IPv6 servers. I found out myself the xbox doesn't like
this at all. My ISP doesnt support IPv6. When I would look at my connection on my xbox it would say IPv4 and IPv6. So O went into my router settings and sure enough my router was set to tunnel IPv4 to IPv6. I went through set to IPv4 only and it solved my
problem. This causes a teredo error in your xbox.

Had similar issues with my X whilst my PS4 Pro worked fine and was advised to use a P2P Powerline Ethernet Adaptor.

You would need a free plug near your router and console, but this was the solution for me.

Personally i used the TP-Link TL PA4010PKIT

It does drop a little of my connection though but still brings through around 230 Mbps of my 300 Mpbs.

I'll take a look! Thanks for the suggestion! My only worry is that I have seen people suffering from the same issue as me while their Xbox is hardwired to their router. So Im not sure the adapter would actually stop me from being disconnected.

I'm not sure. How can I check if my router is tunneling it through Ipv4?

5ghz signals are known to reach shorter distances. So now I know you're using wifi, you need to close that gap or rather extend the reach. A wifi extender will help with that or a mesh system as mentioned before.
Distance and the more walls the signal has to go through effect wifi strength.
