Disable or Remove any 3rd party Firewall Software: If you use any 3rd party networking filtering or Firewall software such as Little Snitch, Kapersky Internet Security, McAfee, LuLu, or similar, then this could be a problem. First, disable the software and then try it for 24 hours. If there are no problems, then 9 times out of 10, that’s the problem. You’ll have to completely remove the software to make sure it doesn’t enable itself.
Redo Network Settings: You may have to redo your wireless network settings. Just go to System Settings > Networking Services > Select Network Name > Click Details > Click the “Forget This Network” button, then add the network back in to this section.
Reset your Router: Refer to your Router’s manual for this step.
Boot into Safe Mode and try WiFi: If all else fails, try booting into Safe Mode. Safe Mode loads the minimum amount of drivers, apps, and what ever else may load when you boot-up a Mac. Getting into Safe Mode depends on what Mac you have.

For Intel Macs, reboot the Mac and hold down the [SHIFT] key until you login to the Mac.
For Apple Silicon Macs (m1, m2, etc), turn the Mac off, let it sit powered off for 10 seconds, then press and hold the POWER button until you see the Options screen. Now press and hold SHIFT key and choose “Continue in Safe Mode” to boot the Mac in Safe Mode.

If all else fails, go to Apple Support at https://support.apple.com/
