1. Quick Fixes (Try These First)

1.1 Restart Your Mac & Router

🔹 Restart your Mac (Apple Menu > Restart).

🔹 Restart your Wi-Fi router (unplug for 30 seconds, then plug back in).

📌 Pro Tip: If using public Wi-Fi, check if there’s a login page (Captive Portal) you need to sign into.

1.4 Try Connecting to a Different Network

🔹 If another Wi-Fi network works, your router may be the issue.

🔹 Try using your phone’s hotspot to check if the problem is with your Mac or the network.

📌 If other devices can connect to the same network, move to the next steps.
