My controller won’t connect to my xbox one s even though it was working perfectly yesterday

Thankyou for the response, I have other things connected to my WiFi and are having no issues with them so my WiFi is on and working, I even pulled out my Xbox one and it’s having the same issues, I’ve reset my Xbox series s, and It won’t even let me finish the setup stages because it just simply won’t connect.

Its not the controller. Tried one thats a year old and still does the samething happens to that one. Even though it works perfectly on my normal xbox one i usedaily using the same controller. It has to be a system issue.

Sounds weird, because my Xbox one s controller works perfectly fine with Bluetooth

I'm back at square one again it was working perfectly fine when I set it up yesterday and come the next day, I turn it on and it won't connect. Even though it finally managed to only 20 minutes later, fast forward a couple of hours it constantly disconnected
me and it wouldn't connect at all. I just don't understand how when I turn off the Xbox S it has a hard time to connect to the router where as everything else manages just fine, at this rate I 'll just have to go back to my original Xbox One.

sorry for not replying. my other xbox one and series s/x controllers work perfectly fine.
