Xbox One X wireless not working properly

Xbox One X wireless not working properly
Hello,

for the past few days I've been having issues when connecting my Xbox One X wirelessly to my network.

Xbox sees my network and when i click connect, I enter the password and then after 20-30 seconds get an troubleshooting network screen. Two days ago i tried hard resetting the console, that didn't help. I've restarted my router multiple times, tried plugging
it out and back in, and tried factory reset... After that i've decided to factory reset xbox, and i succesfully connected to the network... i played for few hours, turned the xbox off, and the next day same problem... this time factory reset didn't work this
time... When i connect my xbox with cable, network works fine. I've checked my router for filtered MAC addresses, everything is ok. I've cleared alternate MAC addresses just in case, still nothing. IP and DNS are set to automatic. I must say that all the
other devices connected to my home network work just fine. There are no new devices in house. My old xbox one also connects without problems. I've tried connecting it to my phone personal hotspot and the problem persists....

Connecting with cable is not an option for me because of the position of TV and Xbox.

Is it possible that wlan adapter inside xbox is faulty? has anyone had that problem?

My warranty ended 2 months ago, is this even worth sending to Microsoft for repair?

thanks..

:)
