MacBook Air keeps disconnecting from wifi

Hello dkdkdkj,

I understand your Mac is disconnecting from Wi-Fi randomly and then has trouble reconnecting. I know how important it can be to have a reliable Wi-Fi connection. I'm happy to help you get to the bottom of why it keeps disconnecting.

Wi-Fi issues like this can sometimes be related to your network. Have you tested out your Mac while connected to a different network to see if the same thing happened? Are other devices able to connect to your Wi-Fi network and stay connected without issue?

Try out these steps and test your Wi-Fi connection after each one:

1. Make sure your software is up to date. If you're using a third-party Wi-Fi router, check with the manufacturer to confirm that it has the latest firmware installed. Use the following steps to update your Mac: How to update the software on your Mac.
2. Verify that all Ethernet and other cables between your Wi-Fi router and modem are securely connected. Sometimes network issues can be caused by loose or disconnected cables. Also, make sure there is no damage to any of your cables.
3. Verify you're using the recommended settings for Wi-Fi routers and access points: Recommended settings for Wi-Fi routers and access points.
4. Check for Wi-Fi interference: Resolve Wi-Fi and Bluetooth issues caused by wireless interference.
5. Power your modem and router off for a few seconds and then power them on again.
