Wi-Fi Protected Setup (WPS)
Enable the Wi-Fi Protected Setup feature. 
Locking the wireless security settings prevents the settings from 
being changed by the Wi-Fi Protected Setup feature of the router. 
Devices can still be added to the network using Wi-Fi Protected 
Setup.  However,  the  settings  of  the  network  will  not  change 
once this option is checked.
A PIN is a unique number that can be used to add the router to 
an existing network or to create a new network. The default PIN 
may be printed on the bottom of the router. For extra security, 
a new PIN can be generated. You can restore the default PIN at 
any time. Only the Administrator (“admin” account) can change 
or reset the PIN. 
Shows the current value of the router’s PIN. 
Restore the default PIN of the router. 
Create a random number that is a valid PIN. This becomes the 
router’s PIN. You can then copy this PIN to the user interface of 
the registrar.
This  Wizard  helps  you  add  wireless  devices  to  the  wireless 
network.
The wizard will either display the wireless network settings to guide you through manual configuration, prompt you to enter the PIN for the device, or ask you 
to press the configuration button on the device. If the device supports Wi-Fi Protected Setup and has a configuration button, you can add it to the network by 
pressing the configuration button on the device and then the on the router within 60 seconds. The status LED on the router will flash three times if the device 
has been successfully added to the network.
There are several ways to add a wireless device to your network. A “registrar” controls access to the wireless network. A registrar only allows devices onto the 
wireless network if you have entered the PIN, or pressed a special Wi-Fi Protected Setup button on the device. The router acts as a registrar for the network, 
although other devices may act as a registrar as well.

Wi-Fi Protected Setup (WPS) System is a simplified method for securing your wireless network during the “Initial setup” as well as the “Add New 
Device” processes. The Wi-Fi Alliance (WFA) has certified it across different products as well as manufactures. The process is just as easy, as depressing 
a button for the Push-Button Method or correctly entering the 8-digit code for the Pin-Code Method. The time reduction in setup and ease of use 
are quite beneficial, while the highest wireless Security setting of WPA2 is automatically used.

equipment, software and peripherals.
Check  PPPoe Pass Through  to allow PPPoE authentication 
to the LAN Clients as an authenticating point.
Unchecking the box will not allow the DIR-857 to respond 
to pings. Blocking the Ping may provide some extra security 
from hackers. Check the box to allow the Internet port to 
be “pinged”.
You may set the port speed of the Internet port to  10Mbps, 
100Mbps , 1000Mbps , or 10/100/1000Mbps 	Auto . Some 
older cable or DSL modems may require you to set the port 
speed to 10Mbps.
