Troubleshooting Mac Wi-Fi:

A few thoughts to try...

I. Clear the Temporary Internet Files:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.
• Go Here: Clear your browsing history in Safari on Mac - Apple Support

II. Restart your Router:

1. Power: off the router
2. Wait: 30 seconds
3. Power: It back on

III. Boot in Safe Mode:

[Hold Down: shift key, upon boot], In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install.

IV. Try a New Admin User:

What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.

Hi,

Try to check your hardware of your MacBook Air with Apple Diagnostics if your WiFi issue is caused by hardware related trouble.

"I have not tried this. But It seems I shut down the system and restarted it and it seems to be working. So perhaps it had to do with my wireless internet in the house. I have a feeling it may be an IP address conflict.[...]"

Dynamic Vs, Static:

If you are using DHCP for assigning an IP address, then all are added as they are available. But, if someone could have assigned their IP address(static), making this conflict to occur. Is, they probably change it to conflict with it, intentional, or not.
