+Switch network interface (NIC), such as `eth0` or `wlan0`, from default *client mode* to *router mode*. Basically, you can use the selected network interface to act as a router for your other network client devices such as mobile phones/tablets/etc... and switch it back to client mode quickly if needed.

+**In the client mode**, the network interface acts normally as it does on your normal client Linux computer. It retrieves a IPv4 from a DHCP server on your local network and acts as client, etc.
 
-In router mode, a DHCP server kicks in and allocates IPv4 addresses for any connected devices which use a DHCP client. This is equivalent to normal stock/home router behavior.
