Hey @SonicCryCanary.
Have you had the chance to try power-cycling your Xbox to see if that helps at all? If it's still happening after that try clearing out the alternate MAC address as well to see if that helps.
To clear out the Alternate MAC Address open up the Settings on your Xbox, then go to Network Settings. From there go to Advanced Options and look for the option to clear the Alternate MAC Address.
Let me know how it goes when you've got the chance. Thanks!
