Manage the DHCP Server Address Pool
By default, the modem router acts as a Dynamic Host Configuration Protocol (DHCP) server. The modem router
assigns IP, DNS server, and default gateway addresses to all computers that are connected to its LAN and WiFi
network. The assigned default gateway address is the LAN address of the modem router.
These addresses must be part of the same IP address subnet as the modem router’s LAN IP address. The default
DHCP address pool is 192.168.1.2–192.168.1.254.
The modem router delivers the following parameters to any LAN device that requests DHCP:
•An IP address from the range that you define
•Gateway IP address (the modem router’s LAN IP address)
•DNS server IP address (the modem router’s LAN IP address)
To specify the pool of IP addresses that the modem router assigns:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. Enter http://www.routerlogin.net.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and password are case-sensitive.
