Disable the DHCP Server Feature in the
Cable Modem Router
By default, the cable modem router acts as a DHCP server. The cable modem router
assigns IP, DNS server, and default gateway addresses to all computers connected to
the LAN. The assigned default gateway address is the LAN address of the cable modem
router.
You can use another device on your network as the DHCP server, or specify the network
settings of all your computers.
To disable the DHCP server feature in the modem router:
1. Launch a web browser from a computer or mobile device that is connected to the
cable modem router network.
2. Enter
http://routerlogin.net
or
http://192.168.0.1
.
A login window opens.
3. Enter the cable modem router admin user name and password.
The user name is
admin
. The password is the one that you specified the first time
that you logged in. The user name and password are case-sensitive.
The BASIC Home page displays.
4. Select
ADVANCED > Setup > LAN Setup.
The LAN Setup page displays.
5. Clear the
Use Router as DHCP Server
check box.
6. Click the
Apply
button.
7. (Optional) If this service is disabled and no other DHCP server is on your network,
set your computer IP addresses manually so that they can access the cable modem
router.
Manage LAN IP Addresses
When you specify a reserved IP address for a computer on the LAN, that computer
always receives the same IP address each time it accesses the cable modem router’s
DHCP server. Assign reserved IP addresses to computers or servers that require
permanent IP settings.
