Disable LED Blinking or Turn Off LEDs
The router LEDs on the top panel indicate router activities and behavior\
. You can disable 
LED blinking for network communications, or turn off all LEDs except the Power LED.
To disable LED blinking or turn off the LEDs:

nnected to the 
network.
2.  T
ype  http://www.routerlogin.net  or http://www.routerlogin.com .

The user name is  admin. 
 The default password is password . The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4.  Select  ADV
 ANCED > Advanced Setup > LED Control Settings . 
By default, the first radio button is selected, which allows standard LE\
D behavior. For 
information about standard LED behavior
 , see Table  1, LED and button descriptions on

View WAN Settings
You can view or configure wide area network (WAN) settings for the Internet port. You can  set up a DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and 
enable the router to respond to a ping to its WAN (Internet) port. 
To view the WAN settings:
1.  Launch an Internet browser from a computer or wireless device that is co\
nnected to the 
network.

The following settings display: • Disable Port Scan and DoS Protection. DoS protection protects your LAN against 
denial of service attacks such as Syn flood, Smurf 

Attack, Ping of Death, and many 
others. Select this check box only in special circumstances. 
• Default DMZ Server . 
 This feature is sometimes helpful when you are playing online 
games or videoconferencing, but it makes the firewall security less effective. See  Set 
Up a Default DMZ Server  on page
  106.
• Respond to Ping on Internet Port . This 
 feature allows your router to be discovered. 
Use this feature only as a diagnostic tool or for a specific reason. 
• Disable IGMP Proxying . IGMP proxying allows a computer on the local area network 
(LAN) to receive the multicast traf
 fic it is interested in from the Internet. If you do not 
need this feature, you can select this check box to disable it.
• MTU Size (in bytes). 
 The normal MTU (maximum transmit unit) value for most 
Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Ch\
ange the 
MTU only if you are sure that it is necessary for your ISP connection. S\
ee  Change the 
MTU Size on page  39.
• NA
T Filtering . Network Address Translation (NAT) determines how the router 
processes inbound traffic. Secured NAT protects computers on the LAN from attacks 
from the Internet, but might prevent some Internet games, point-to-point\
 applications, 
or multimedia applications from working. Open NAT provides a much less secured 
firewall, but allows almost all Internet applications to work.

Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and 
videoconferencing applications that are incompatible with Network Address Translation 
(NAT). The router is programmed to recognize some of these applications and to work 
correctly with them, but other applications might not function well. In some cases, one local 
computer can run the application correctly if the IP address for that computer is entered as 
the default DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the 
default DMZ server loses much of the protection of the firewall and 
is exposed to exploits from the Internet. If compromised, the DMZ 
server computer can be used to attack other computers on your 
network.
The router usually detects and discards incoming traffic from the Internet that is not a 
response to one of your local computers or a service that you have configured in the Port 
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have the router 
forward the traffic to one computer on your network. This computer is called the default DMZ 
server.
To set up a default DMZ server: 
1. Launch an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the router user name and password.
The user name is admin. The default password is password. The user name and 
password are case-sensitive.

The router’s device name is R6700. This device name displays in a file manager when you 
browse your network.
To change the router’s device name:

network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.

6. Click the Apply button.

Change the LAN TCP/IP Settings
The router is preconfigured to use private IP addresses on the LAN side and to act as a 
DHCP server. The router’s default LAN IP configuration is as follows:
•LAN IP address. 192.168.1.1
•Subnet mask. 255.255.255.0
These addresses are part of the designated private address range for use in private networks 
and are suitable for most applications. If your network requires a different IP addressing 
scheme, you can change these settings.
You might want to change the settings if you need a specific IP subnet that one or more 
devices on the network uses or if you use competing subnets with the same IP scheme.
To change the LAN TCP/IP settings:
1. Launch an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.

5. In the IP Address fields, type the IP address.
6.  In the IP Subnet Mask  fields, type the subnet mask of the router. 
The IP address and subnet mask identify which addresses are local to a s\
pecific device  and which must be reached through a gateway or router.
7.  Change the RIP settings.
Router Information Protocol (RIP) allows a router to exchange routing \
information with 
other routers. 
a. In the RIP Direction list, select one of the following:
• Both. 
The router broadcasts its routing table periodically and incorporates 
information that it receives.
• Out Only . 
 The router broadcasts its routing table periodically. 
• In Only . 
 The router incorporates the RIP information that it receives.
b.  In the RIP V
 ersion list, select one of the following:
• Disabled. 
 This is the default setting. 
• RIP-1. 
This format is universally supported. It is adequate for most networks, \
unless you use an unusual network setup. 
• RIP-2. 
This format carries more information. Both RIP-2B and RIP-2M send the 
routing data in RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M us\
es 
multicasting.

o reconnect, close your browser, relaunch it, and log in to the router.
Specify the IP Addresses That the Router Assigns
By default, the router acts as a Dynamic Host Configuration Protocol (D\
HCP) server. The 
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 router. 
These addresses must be part of the same IP address subnet as the router\
’s LAN IP  address. Using the default addressing scheme, define a range between 192\
.168.1.2 and 
192.168.1.254, although you can save part of the range for devices with \
fixed addresses.
To specify the pool of IP addresses that the router assigns:
1.  Launch an Internet browser from a computer or wireless device that is co\
nnected to the 
network.
2.  T
ype  http://www.routerlogin.net  or http://www.routerlogin.com .

4.  Select  ADV
 ANCED > Setup > LAN Setup .
5. Make sure that the  Use Router as DHCP Server  check box is selected.
6.  Specify the range of IP addresses that the router assigns:
a. In the  Starting IP 
 Address field, type the lowest number in the range.
This IP address must be in the same subnet as the router.

110 Nighthawk AC1750 Smart WiFi Router 
b. In the Ending IP Address field, type the number at the end of the range of IP 
addresses.
This IP address must be in the same subnet as the router.
7. Click the Apply button.
Your settings are saved.
The router delivers the following parameters to any LAN device that requests DHCP:
•An IP address from the range that you define
•Subnet mask
•Gateway IP address (the router’s LAN IP address)
•DNS server IP address (the router’s LAN IP address)
Disable the DHCP Server Feature in the Router
By default, the router acts as a DHCP server. The 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 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 router:
1. Launch an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the router user name and password.
