Reset your router: Let's first make sure it's not your router's fault.
Restart your PC: Sometimes a reboot can fix this problem.
Reset Windows 11 network settings: Type the word Settings in the search box at the bottom of the screen. Select Network and internet > Advanced network settings. Scroll down and select Network reset. Select Reset now > Yes to confirm.
