Reserve a LAN IP for a device
The mAX router assigns an IP address for every device that joins your mAX Wi-Fi home
network. This is called DHCP and allows your devices to join the home network and have
connectivity to the Internet. Typically, there is no need to make any changes to this support.
However, in some cases you may want to establish fixed (or reserved) IP addresses for
particular devices in your network. This is called LAN IP reservation and it ensures a device is
always accessible at a specific IP address. Examples of this include setting up a file or media
server.

Configure LAN Subnet and DHCP range
A LAN subnet is a prescribed prefix for the first three sets of numbers in your networks
IP addresses. The default value is 192.168.7.# which means all the IP address of your
devices (including your mAX router) will begin with those numbers. Your mAX router will
automatically be assigned the first value, 192.168.7.1. If you change to another subnet, your
router will retain the first number for that subnet.
DHCP range is the range of IP addresses inside your selected Subnet. Your mAX router will
handle the assignment of all your devices by using the addresses in this range. The exception
will be if you have configured IP reservations as described in
(page 37). Any devices utilizing LAN IP reservations will not use DHCP.
