Connect to a network

If you change the settings of your network connection or connect to a different network than usual, you may have to enable the connection yourself.

If your network connection is managed by Network Manager the connection should be enabled automatically.

If the connection is not enabled automatically:

Find the Network Manager icon in the notification area. It should look like a small signal strength indicator or a computer monitor and will probably be close to the clock
Right-click the icon and ensure that Enable Networking is selected in the popup menu.
If you have a wireless network connection, make sure that Enable Wireless is selected.
Left-click the Network Manager icon and then click on the network you want to connect to
After a short period you should receive a message which says Connection Established
You should now be connected to a network.

If you are not connected to a network after following the procedure above:

Ifup is a command-line tool for enabling network connections.

To enable a network connection:

Press Applications → Accessories → Terminal to open a terminal.
Type sudo ifdown eth1 in the terminal and press Return. Replace eth1 with the name of your network interface if it is different.
Enter your password if prompted.
Type sudo ifup eth1 in the terminal and press Return, again replacing eth1 with the name of your network interface.
If you have connected successfully, you should see a message similar to the following:
```
DHCPACK from 192.168.2.1
bound to 192.168.2.4 -- renewal in 536349522 seconds.
```
