DHCP IP address (default: 192.168.1.29) is aaa.bbb.ccc.eee where aaa.bbb.ccc is the bitwise AND result of

the LAN IP address and the LAN netmask, and eee = ddd + n - 1.

A cmd apply followed by a cmd save are required for this command to take effect.

lanip iii.iii.iii.iii

Sets the IP address of the modem on the LAN.

iii.iii.iii.iii = 0.0.0.0 to 255.255.255.255 LAN IP address of the modem in decimal (default: 192.168.1.1)

Note: Special care must be taken when configuring this command, if an improperly configured lanip IP

address is entered the ethernet port can be rendered unusable. Before configuring this command it is

advisable to make sure that a command console is available via the serial port, or the IP address is known

and remote telnet is enabled to allow the modem to be accessed wirelessly.

The current LAN IP address can be queried by using lanip.
