Wireless Security Mode: Enable WPA/WPA2 Wireless Security (enhanced)
Wi-Fi Protected Access (WPA) is a more advanced and up to date wire\fess encryption method used today. This is the recommended wire\fess 
security option. 
The fo\f\fowin\b parameters wi\f\f be avai\fab\fe for confi\buration:
\fipher Type: Se\fect the appropriate cipher type to use here. 
Options to choose from are Tempora\f Key 
Inte\brity Protoco\f (TKIP), Advanced Encryp -
tion Standard (AES), and Both (Auto.TKIP and 
AES).
Network Key: Enter the shared secret used here. This secret 
phrase needs to be the same on a\f\f\u of the 
wire\fess c\fients for them to be ab\fe to connect 
to the wire\fess network successfu\f\fy.

Section 4 - Security
Wireless Security
This  section  wi\f\f  show  you  the  different  \feve\fs  of  security  you  can  use  to  protect  your  data  from  intruders.  The  DIR-850L  offers  the 
fo\f\fowin\b types of security:
 • WPA2 (Wi-Fi Protected Access 2)       • WPA2-PSK (Pre-Shared Key)
  • WPA (Wi-Fi Protected Access)        • WPA-PSK (Pre-Shared Key)
What is WPA?
WPA (Wi-Fi Protected Access), is a Wi-Fi standard that was desi\bned to improve the security features of WEP (Wired Equiva\fent Privacy).  
The 2 major improvements over WEP: 
• Improved data encryption throu\bh the Tempora\f Key Inte\brity Protoco\f (TKIP). TKIP scramb\fes the keys usin\b a hashin\b 
a\f\borithm  and,  by  addin\b  an  inte\brity-checkin\b  feature,  ensures  that  the  keys  haven’t  been  tampered  with. WPA2  is 
based on 802.11i a\und uses Advanced Encryption Standard (AES) instead of TKIP.
•  User  authentication,  which  is  \benera\f\fy  missin\b  in  WEP,  throu\bh  the  extensib\fe  authentication  protoco\f  (EAP).  WEP 
re\bu\fates access to a wire\fess network based on a computer’s hardware-specific MAC address, which is re\fative\fy simp\fe 
to be sniffed out and sto\fen. EAP is bui\ft on a more secure pub\fic-key encryption system to ensure that on\fy authorized 
network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wire\fess connection. The key is an a\fpha-numeric password between 
8 and 63 characters \fon\b. The password can inc\fude symbo\fs (!?*&_) and spaces. This key must be the exact same key entered on your 
wire\fess router or access point.
WPA/WPA2 incorporates user authentication throu\bh the Extensib\fe Authentication Protoco\f (EAP). EAP is bui\ft on a more secure pub\fic 
key encryption system to ensure that on\fy authorized network users can access the network.

DH\fP Server Settings
DHCP stands for Dynamic Host Contro\f Protoco\f. The DIR-850L has a bui\ft-in DHCP server. The DHCP Server wi\f\f automatica\f\fy 
assi\bn an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP c\fients by settin\b 
their TCP/IP settin\bs to “Obtain an IP Address Automatica\f\fy.” When you turn your computers on, they wi\f\f automatica\f\fy \foad 
the proper TCP/IP settin\bs provided by the DIR-850L. The DHCP Server wi\f\f automatica\f\fy a\f\focate an unused IP address from 
the IP address poo\f to the requestin\b computer. You must specify the s\utartin\b and endin\b addr\uess of the IP address poo\f.
Check  this  box  to  enab\fe  the  DHCP  server  on  your  router. 
Uncheck to disab\fe this function.
Enter  the  startin\b  and  endin\b  IP  addresses  for  the  DHCP 
server’s IP assi\bnment.
Note:  If  you  statically  (manually)  assign  IP  addresses  to  your 
computers or de\fices, make sure the IP addresses are outside 
of this range or you may ha\fe an IP conflict. 
The \fen\bth of time for the IP address \fease. Enter the Lease 
time in minutes.
If  a\f\f  the  computers  on  the  LAN  successfu\f\fy  obtain  their 
IP  addresses  from  the  router’s  DHCP  server  as  expected, 
this  option  can  remain  disab\fed.  However,  if  one  of  the 
computers on the LAN fai\fs to obtain an IP address from the 
router’s  DHCP  server,  it  may  have  an  o\fd  DHCP  c\fient  that 
incorrect\fy  turns  off  the  broadcast  fla\b  of  DHCP  packets. 
Enab\fin\b this option wi\f\f cause the router to a\fways broadcast its responses to a\f\f c\fients, thereby workin\b around the prob\fem, at 
the cost of increased broadcast traffic on the LAN.
Check  this  box  to  a\f\fow  the  DHCP  Server  to  offer  NetBIOS  confi\buration  settin\bs  to  the  LAN  hosts.  NetBIOS  a\f\fow  LAN  hosts  to 
discover a\f\f other computers within the network, e.\b. within Network Nei\bhborhood.
If  NetBIOS  announcement  is  switched  on,  it  wi\f\f  cause WINS  information  to  be  \fearned  from  the WAN  side,  if  avai\fab\fe. Turn  this

This fie\fd indicates how network hosts are to perform NetBIOS name re\bistration and discovery. H-Node, this indicates a Hybrid-State

have confi\bured WINS servers. M-Node (defau\ft), this indicates a Mixed-Mode of operation. First Broadcast operation is performed 
to re\bister hosts and discover other hosts, if broadcast operation fai\fs, WINS servers are tried, if any. This mode favours broadcast 
operation which may be preferred if WINS servers are reachab\fe by a s\fow network \fink and the majority of network services such as 
servers and printers are \foca\f to the LAN. P-Node, this indicates to use WINS servers ONLY. This settin\b is usefu\f to force a\f\f NetBIOS 
operation to the confi\bured WINS servers. You must have confi\bured at \feast the primary WINS server IP to point to a workin\b WINS 
server. B-Node, this indicates to use \foca\f network broadcast ONLY. This settin\b is usefu\f where there are no WINS servers avai\fab\fe, 
however,  it  is  preferred  you  try  M-Node  operation  first. This  settin\b  has  no  effect  if  the ‘Learn  NetBIOS  information  from WAN’  is
