Connect to a wireless network

If you have a wireless-enabled computer, you can connect to a wireless network that is within range to get access to the internet, view shared files on the network, and so on.

  1. If you have a wireless hardware switch on your computer, make sure that it is turned on.

  2. Click the network menu in the menu bar, and click the name of the network you want to connect to. If the name of the network isn't in the list, select More Networks to see if the network is further down the list. If you still don't see the network, you may be out of range or the network might be hidden.

  3. If the network is protected by a password (encryption key), enter the password when prompted and click Connect. If you do not know the key, it may be written on the underside of the wireless router or base station, in its instruction manual, or you may have to ask the person who administers the wireless network.

  4. The network icon will change appearance as the computer attempts to connect to the network.

  5. If the connection is successful, the icon will change to a dot with several bars above it. More bars indicate a stronger connection to the network. If there aren't many bars, the connection is weak and might not be very reliable.

If the connection is not successful, you may be asked for your password again or it might just tell you that the connection has been disconnected. There are a number of things that could have caused this to happen. You could have entered the wrong password, the wireless signal could be too weak, or your computer's wireless card might have a problem, for example. See Wireless network troubleshooter for more help.

A stronger connection to a wireless network does not necessarily mean that you have a faster internet connection, or that you will have faster download speeds. The wireless connection connects your computer to the device which provides the internet connection (like a router or modem), but the two connections are actually different, and so will run at different speeds.

Thank you. However on Ubuntu 12.10 I cannot see the wireless network at all. I know the network is working as I have other devices connected to it. It will not detect any networks at all. –  Paul Hennessy Oct 23 '12 at 10:29

Make sure that you have the driver enabled for your wireless card. In order to do this, go to settings>software sources>additional drivers. You may need to temporarily use a wired connection to activate the driver.
