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 192.168.0.10–192.168.0.254, with IP address 
192.168.0.10 reserved for ReadySHARE. The first IP address that the DHCP server can 
assign to an attached device is 192.168.0.11.
The modem 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 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 an Internet browser from a computer or WiFi device that is connected to the 
network.
2. Type http://www.routerlogin.net.
A login window opens.
3. Type admin for the user name and type your password.
If you did not yet personalize your password, type password for the password.

Make sure that the Use Gateway as DHCP Server  check box is selected.
This check box is selected by default.
7.  Specify the range of IP addresses that the  modem router assigns:
• In the Starting IP 
 Address field, enter the lowest number in the range.
This IP address must be in the same subnet as the modem router. By defau\
lt, the  starting IP address is 192.168.0.2.
• In the Ending IP 
 Address field, enter the number at the end of the range of IP 
addresses.
This IP address must be in the same subnet as the modem router. By defau\
lt, the  ending IP address is 192.168.0.254.
8.  Click the  Apply button.

Manage Universal Plug and Play
Universal Plug and Play (UPnP) enables devices, such as Internet devic\
es and computers, to 
access the network and connect to other devices as needed. UPnP devices \
can 
automatically discover the services from other registered UPnP devices o\
n the network.
If you use applications such as multiplayer gaming, peer-to-peer connect\
ions, or real-time 
communications such as instant messaging or remote assistance, NETGEAR r\
ecommends 
that you keep UPnP enabled, which is the default setting.

To manage Universal Plug and Play:
1. 
Launch an Internet browser from a computer or WiFi device that is connec\
ted to the 
network. 
2.  T
ype  http://www.routerlogin.net .
A login window opens.

4.  Click the  OK button. 
The BASIC Home page displays.
5.  Select  ADV
 ANCED > Advanced Setup >  UPnP.
The previous figure shows sample entries in the UPnP Portmap Table.
The UPnP Portmap Table displays the IP address of each UPnP device that is accessing 
the modem router and which internal and external ports that device opene\
d. 
 The UPnP 
Portmap Table also displays what type of port (that is, the protocol that is ass\
ociated with 
the port) is open and whether that port is still active for each IP add\
ress.
6.  T
o turn off UPnP, clear the  Turn UPnP On check box. 
By default, this check box is selected. If you clear the T
 urn UPnP On check box, the 
modem router does not allow any device to automatically control the reso\
urces, such as 
port forwarding (mapping), of the modem router. 
7.  T
o change the advertisement period, in the  Advertisement Period field, enter a new period 
in minutes.
The advertisement period specifies how often the modem router broadcasts\
 its UPnP  information. 
 This value can range from 1 to 1440 minutes. The default period is 
30
  minutes. Shorter durations ensure that control points can obtain current\
 device status

at the expense of additional network traffic. Longer durations can compromise the 
freshness of the device status but can significantly reduce network traffic.
8. To change the advertisement time to live value, in the Advertisement Time to Live field, 
enter a new value in hops.
The time to live for the advertisement is measured in hops (steps) for each UPnP packet 
sent. Hops are the steps a packet takes between routers. The number of hops can range 
from 1 to 255. The default value for the advertisement time to live is 4 hops, which is fine 
for most home networks. If you notice that some devices are not being updated or 
reached correctly, it might be necessary to increase this value.
9. Click the Apply button.
Your settings are saved.
10. To refresh the information in the UPnP Portmap Table, click the Refresh button.
The information onscreen is updated.
