Section 3 - Conguration
DHCP Server Settings
DHCP stands for Dynamic Host Control Protocol. The DIR-802 has a built-in DHCP server. The DHCP Server will automatically 
assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting 
their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load 
the proper TCP/IP settings provided by the DIR-802. The DHCP Server will automatically allocate an unused IP address from 
the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.
Check this box to enable the DHCP server on your router. 
Uncheck to disable this function.
Enter the  starting and  ending IP addresses  for the  DHCP 
server’s IP assignment.
Note: If you statically (manually) assign IP addresses to your 
computers or devices, make sure the IP addresses are outside 
of this range or you may have an IP conict. 
The length of time for the IP address lease. Enter the Lease 
time in minutes.
If  all the  computers  on  the LAN successfully  obtain  their 
IP  addresses  from  the  router’s DHCP  server  as  expected, 
this  option  can  remain  disabled. However,  if one  of  the 
computers on the LAN fails to obtain an IP address from the 
router’s DHCP server, it may have an old DHCP client that 
incorrectly  turns  o  the  broadcast  ag  of  DHCP  packets. 
Enabling this option will cause the router to always broadcast its responses to all clients, thereby working around the problem, at 
the cost of increased broadcast trac on the LAN.
Check this box to allow the DHCP Server to oer NetBIOS conguration settings to the LAN hosts. NetBIOS allow LAN hosts to 
discover all other computers within the network, e.g. within Network Neighborhood.
If NetBIOS announcement is switched on, it will cause WINS information to be learned from the WAN side, if available. Turn this 
setting o to congure manually.
