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:

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. For instructions, go here: How to Use safe Mode on your Mac - Apple Support

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.

Are you running a 7 year old operating system?

Some Macs did not come with WiFi many years ago, and add on WiFi cards are necessary.

Some Macs if they are old could have gotten damaged internally on the WiFi card or card connectors and need an authorized service technician to verify this is not the case. A WiFi/Ethernet bridge is frequently preferable in such scenarios. There are also WiFi ethernet dongles.

It really helps to provide us with the exact model of your Mac when asking for assistance. You can get his information by clicking the Apple menu and selecting "About This Mac".

If you had working WiFi in this Mac previously, then it most likely means you have a hardware failure of some sort which will need to be repaired.
