My iMac's Internet has randomly stopped working. It connects to the wifi just fine but it doesn't connect to the Internet. My iPhone and other devices are on the same network and they all work just fine. I've restarted the Internet and computer multiple times now but still no luck.
iMac (27-inch, Late 2012), OS X Yosemite (10.10.5)
Howdy there Mario 95,
It sounds like you need to figure out why you can connect to your network but have no internet access. I would use the Wireless Diagnostics Assistant to help you determine the cause of the issue:
Use Wireless Diagnostics to help you resolve Wi-Fi issues on your Mac
Thank you for using Apple Support Communities.
I Already did this. It says all is good but I can't connect to the internet. It didn't help at all.
Thanks for the update. I would next restart your router and/or modem by unplugging them for about 30 seconds. Once they are back on and you can connect to the internet with other devices test the issue again from the iMac.
If it persists then I would recreate the Wi-Fi network service in your System Preferences.
1. Disconnect from the Wi-Fi network if you are already connected
2. Click System Preferences
3. Click the Network icon
4. Click the Wi-Fi connection in the list you see to the left
5. Click the minus button to the bottom left of the list
6. Restart the computer
7. Go back to Network in System Preferences
8. Click the '+' in the lower left of the network services list
9. Click Wi-Fi from the dropdown menu labeled 'Interface'
10. Leave service name at default (It should say 'Wi-Fi') and click Create
Then attempt joining the network again and getting to the internet.
iMac connects to wifi but not the internet.
