Usually, only the system administrator can activate and deactivate network interfaces.
If you want any user to be able to activate this interface via KInternet, select Enable
Device Control for Non-root User via Kinternet.
Setting Up Maximum Transfer Unit Size
You can set a maximum transmission unit (MTU) for the interface. MTU refers to the
largest allowed packet size in bytes. A higher MTU brings higher bandwidth efficiency.
However, large packets can block up a slow interface for some time, increasing the lag
for further packets.

2 In the General tab, select the desired entry from the Set MTU list.

Settings and click Edit.
Choose At Boot Time to start the device during the system boot. With On Cable
Connection, the interface is watched for any existing physical connection. With
On Hotplug, the interface is set as soon as available. It is similar to the At Boot
Time option, and only differs in the fact that no error occurs if the interface is
not present at boot time. Choose Manually to control the interface manually with
ifup or KInternet. Choose Never to not start the device at all. The On NFSroot
is similar to At Boot Time, but the interface is does not shut down with the
rcnetwork stop command. Use this if you use an nfs or iscsi root file system.
