connected to wifi but no internet

Hi Jyea8,

Welcome to the Apple Community.

It's great you have tried several things to solve the problem!

Wondering which Mac OS is installed on your MacBook Air, could your system need updating to the latest Mac OS ?

and

if you are using Safari, have you tried to access the Internet via another browser (eg Firefox, etc)..

Does your Mac have enough memory / storage space free (at least 50Gb) for your Mac to operate smoothly ?

Is it possible that third party (non-Apple) software (unneecessary Anti-virus, Add-blockers etc.) be interfering with the operating system of your Mac. If so, try again, after turning them off, or use an uninstaller from the developer.

Apple support have a couple of articles online that may help troubleshoot.

Connect to the internet with your Mac.

If your Mac doesn't connect to the Internet over Wi-Fi. (Did you run "Diagnostics" or "Wireless Diagnostics ?)

Sorry I'm no expert. We are all Apple users, like yourself, volunteering our time to help troubleshoot.

However, with a few more answers available, some of the experts who volunteer may choose to help.

You might want to take your Mac to an Apple Store near you:

A Genius Bar reservation is recommended:

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.

V. Reset your SMC and your NVRAM:

(Applies to Intel-Basel Macs Only) Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. Networking) become corrupted, technically. So, reset both on your Mac. So, reset the SMC and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.
