In order to successfully access the Internet, you need to make sure that your DNS Settings are correct. If you find that you are unable to access webpages in any browser, this could be the cause.

To access this setting:

1. Go to the Apple menu and click on System Preferences .
   
    
2. In the System Preferences  window, go to Network.
   
    
3. Click on Advanced... at the bottom of the Network Preferences window.
   
    
4. In the Advanced pop-up box, click on the DNS tab.
   
    
5. In the DNS tab, if you see an address that does not start with 10.82.XX.XX (aside from 10.83.0.121), you will want to remove it by clicking on the address, and then hitting the – button below the box.
   
    
6. After Deleting any addresses that don't belong, your DNS settings box should look like this. If other DNS Servers apart from those listed are present, they will block all connections.
   
   If you don't see all of the addresses in the screenshot below, you can click the + button and add them manually.
   
    
7. Hit OK, and when you close out of the Network window, make sure to hit Apply.
   
    
8. After this step, you should run a Malware Check, as a change in DNS Settings is often caused by Malware. To do this, follow this guide: What should I do if I suspect I have a virus or malware?
    
9. You also need to check if you have a VPN installed - devices with VPN Extensions are unable to connect to the Scotch WiFi. You can remove these through the settings page in Google Chrome .
