Be sure to select File => Save to save the changes.
After adding the wireless device, you can edit its configuration by selecting the device from the device
list and clicking Edit. For example, you can configure the device to activate at boot time.
When the device is added, it is not activated immediately, as seen by its Inactive status. To activate
the device, select it from the device list, and click the Activate button. If the system is configured
to activate the device when the computer starts (the default), this step does not have to be performed
again.

19.9. Managing DNS Settings

The DNS tab allows you to configure the system's hostname, domain, name servers, and search do-
main. Name servers are used to look up other hosts on the network.
If the DNS server names are retrieved from DHCP or PPPoE (or retrieved from the ISP), do not add
primary, secondary, or tertiary DNS servers.
If the hostname is retrieved dynamically from DHCP or PPPoE (or retrieved from the ISP), do not
change it.
