Beta Insider preview loses WiFi connection details when turned off overnight.

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.

Hardwired the Xbox one x never has a problem. ....

In that case, Microsoft is investigating reports of people that have trouble with WiFi staying connected.

If you want to help in that case, please download the Xbox Insider App, and whenever you lose connectivity to your WiFi, hold the Xbox button on the controller, and go to the Feedback/Report a problem tile.

Choose the most appropriate category for your issue, and then describe when and what happened. Then send in the report through the Insider App.

If you're adventurous, you might even try to sign up for gamma or beta ring preview software, to find out if they have improved the WiFi in newer builds.

Ports and your ISP usually don't have anything to do with a wireless connection failing, as the WiFi connection is only between your console and the router.

Is your console by chance enrolled in the Insider Preview Program?

While my Xbox One X works without issues via WiFi, the patch notes on some Insider Previews state that they are investigating cases with WiFi connectivity issues, and that people should report via the Feedback tool if their console loses WiFi connectivity.

It would help if you also said which WiFi router you are using, maybe there is an incompatibility between the Xbox One X and certain router models.

I live in the same house as my mum and my brother, and my brother has an xbox, and has not encountered this problem, so I doubt it would be the wifi. Also I turn my xbox off at the wall every night, so it won't have a connection to the wifi overnight.
Still doesn't fix it.

It turns out that my router has scheduled reboots on Wednesday and Saturday. Since turning the scheduled reboots off, I no longer have issues with the wireless on the Xbox. Guess the Xbox can't withstand losing its wifi connection when it is turned off
in instant on mode or essentially sleep mode.
