Your Mac WiFi is slow after a macOS update
Updates can reset WiFi drivers and network settings. Restart your Mac, then restart your router. That fixes most post-update slowness within minutes.
When macOS updates, WiFi drivers restart and network settings can get reset. This makes your connection slower than it should be. A restart of both your Mac and router fixes this quickly.
