Connection Isn’t Working
There are a few possible reasons your internet connection isn’t working.
Is your WiFi setting turned on?
If you aren’t able to get a network to connect, look on the left side of the Networks panel, to make sure WiFi is turned on and you're not in Offline mode. If you're looking for a hidden network, press the 'Add new connection' button on the upper right of the panel and type its information in the New connection settings screen.
Have you connected to a network?
Most people will want to get online with a WiFi connection. Click on the Networks panel in the toolbar and you should see your wireless connection listed on the right side. Just click the connect button to get online. If your access point needs a password, you’ll be asked for it here. And that's all you should need.
Are you accessing the internet through your company’s firewall?
Another reason you may be having trouble connecting is if you are within a network that uses firewall settings. If you are connecting to the internet within your company’s firewall, contact your company’s IT support to find out what proxy and port to use. To update your network proxy configuration with that information, open the Applications panel, and select Accessories > Settings. On the right in the Hardware group, select Network Proxy. Select the Manual proxy configuration option and enter the proxy and port information there.
Has your computer's wireless network switch been turned off?
If you don’t see any WiFi networks and the WiFi switch in the Networks panel is disabled, check for a small switch on one of the sides of your computer. Accidentally bumping your computer’s wireless network switch can disable WiFi on your computer. Try flipping this switch to see if that enables the WiFi switch in the Networks panel, showing you the list of available networks.
