Xbox will stay connected to wifi but loses connection to xbox live

have you tried restarting your router?

do that then power cycle your Xbox.

if that doesn't work you could try https://beta.support.xbox.com/help/Hardware-Network/connect-network/xbox-one-network-connection.

but it could also be due to the high demand on the Xbox (and game) servers as well as increased traffic for ISPs during the current global situation

It affects my other xbox one as well. So its not the wifi card. They stay connected to wifi, but not live

Your post makes no sense. You say you lose connection to Xbox Live, but come across as your Xbox One stays connected. If you can connect to the internet then Live should work without issues unless their is a known Xbox Live issue.

Have you tried alt ports and if both xboxs are on the default also emfi could do it

While my Project Scorpio doesn't seem to have that issue, and stays connected to my network, I read in the release notes in the Insider Preview system updates, that they are investigating these complaints about the WiFi losing connection.

If that happens, please hold the Xbox button on the controller as if you were trying to shut down the console, and instead of turning off the console, go to the Feedback button on the right.

There send feedback describing your WiFi issue, and the console will collect system state data, that would help the engineers get to the cause of the issue of losing WiFi.
