LAN sa vypnúť NEDÁ. Tá IP adresa 192.168.0.1 je totiž IP adresa routeru, potrebná pre vstup do administrácie. LAN je STÁLE pripojená - odpojiť sa nedá (ak by si ju odpojil, ostal by si bez možnosti vstupu do administrácie routera). Viaceré routery totiž nepovoľujú vstup do administrácie cez WiFi (riziko napadnutia zvonku cez WiFi).

You can configure the IP parameters of LAN on this page.

MAC Address - The physical address of the LAN ports, as seen from the LAN. The value cannot be changed.
IP Address - Enter the IP address of your Router in dotted-decimal notation (factory default - 192.168.0.1).
Subnet Mask - An address code that determines the size of the network. Usually it is 255.255.255.0.
IGMP Proxy - If you want to watch TV through IGMP, please Enable it.

Note:

If you change the LAN IP address, you must use the new IP address to login to the Router.
If the new LAN IP address you set is not in the same subnet with the previous one, the IP Address pool in the DHCP server will be configured automatically, but the Virtual Server and DMZ Host will not take effect until they are re-configured"
a pochopíš... Zmeniť môžeš, ale nie vyradiť.
