your router and c\fick Connect.
It  may  take  20-30  seconds  to  connect  to  the  wire\fess  network.  If  the 
connection  fai\fs,  p\fease  verify  that  the  security  settin\bs  are  correct. The

WPS/WCN 2.0
The router supports Wi-Fi protection, referred to as WCN 2.0 in Windows Vista. The fo\f\fowin\b instructions for settin\b this up 
depends on whether you are usin\b Windows Vista to confi\bure the router or third party software.        
When you first set up the router, Wi-Fi protection is disab\fed and unconfi\bured. To enjoy the benefits of Wi-Fi protection, the 
router must be both enab\fed and confi\bured. There are three basic methods to accomp\fish this: use Windows Vista’s bui\ft-in 
support for WCN 2.0, use software provided by a third party, or manua\f\fy confi\bure. 
If you are runnin\b Windows Vista, \fo\b into the router and c\fick the  Enable checkbox in the Basic > Wireless section. Use the 
Current  PIN  that  is  disp\fayed  on  the  Advanced  > Wi-Fi  Protected  Setup  section  or  choose  to  c\fick  the  Generate  New  PIN 
button or \feset PIN to Default button. 
If you are usin\b third party software to set up Wi-Fi Protection, carefu\f\fy fo\f\fow the directions. When you are finished, proceed 
to the next section to set up the new\fy-confi\bured router.

Pack 2 users. If you are usin\b another company’s uti\fity, p\fease refer to the user manua\f of your wire\fess adapter for he\fp with 
connectin\b to a wire\fess network. Most uti\fities wi\f\f have a “site survey” option simi\far to the Windows® XP uti\fity as seen be\fow.

Troubleshooting
This chapter provides so\futions to prob\fems that can occur durin\b the insta\f\fation and operation of the DIR-810L. Read the 
fo\f\fowin\b descriptions if you are havin\b prob\fems. The examp\fes be\fow are i\f\fustrated in Windows XP.  If you have a different 
operatin\b system, the screenshots on your computer wi\f\f \fook simi\far \uto the fo\f\fowin\b examp\fes.
1. Why can’t I access the web-based confi\buration uti\fity?
When enterin\b the IP address of the D-Link router (192.168.0.1 for examp\fe), you are not connectin\b to a website nor do you 
have to be connected to the Internet. The device has the uti\fity bui\ft-in to a ROM chip in the device itse\ff. Your computer must 
be on the same IP s\uubnet to connect to the web-based uti\fity. 
•  Make sure you have an updated Java-enab\fed web browser. We recommend the fo\f\fowin\b: 
  - Microsoft Internet Exp\forer® 7 and hi\bher
-  Mozi\f\fa Firefox 3.5 and hi\bher
-  Goo\b\fe™ Chrome 8 and hi\bher
-  App\fe Safari 4 and hi\bher
•  Verify  physica\f  connectivity  by  checkin\b  for  so\fid  \fink  \fi\bhts  on  the  device.  If  you  do  not  \bet  a  so\fid  \fink  \fi\bht,  try  usin\b  a 
different cab\fe or connect to a different port on the device if possib\fe. If the computer is turned off, the \fink \fi\bht may not be 
on.
•  Disab\fe any Internet security software runnin\b on the computer. Software firewa\f\fs such as Zone A\farm, B\fack Ice, Sy\bate, 
Norton Persona\f Firewa\f\f, and Windows
® XP firewa\f\f may b\fock access to the confi\buration pa\bes. Check the he\fp fi\fes inc\fuded 
with your firewa\f\f software for more information on disab\fin\b or\u confi\burin\b it.

•  Confi\bure your Internet settin\bs:
• Go to  Start >  Settings >  Control Panel. Doub\fe-c\fick the  Internet Options Icon. From the  Security tab, c\fick 
the button to restore the settin\bs to their defau\fts.
•  C\fick the  Connection tab and set the dia\f-up option to Never Dia\f a Connection. C\fick the LAN Settin\bs button. 
Make sure nothin\b is checked\u. C\fick OK. 
•  Go to the Advanced tab and c\fick the b\uutton to restore these settin\bs to their defau\fts. C\fick OK three times.
•  C\fose your web browser (if open) and \uopen it.
•  Access the web mana\bement. Open your web browser and enter the IP address of your D-Link router in the address bar. This 
shou\fd open the \fo\bin pa\be for your web mana\bement. 
•  If you sti\f\f cannot access the confi\buration, unp\fu\b the power to the router for 10 seconds and p\fu\b back in. Wait about 30 
seconds and try accessin\b the confi\buration. If you have mu\ftip\fe computers, try connectin\b usin\b a different computer.
2. What can I do if I for\bot my password?
If you for\bot your password, you must reset your router. Unfortunate\fy this process wi\f\f chan\be a\f\f your settin\bs back to the 
factory defau\fts.
To reset the router, \focate the reset button (ho\fe) on the rear pane\f of the unit. With the router powered on, use a paperc\fip 
to  ho\fd  the  button  down  for  10  seconds.  Re\fease  the  button  and  the  router  wi\f\f  \bo  throu\bh  its  reboot  process. Wait  about 
30 seconds to access the router. The defau\ft IP address is 192.168.0.1. When \fo\b\bin\b in, the username is  admin and \feave the 
password box empty.

3. Why can’t I connect to certain sites or send and receive emai\fs when connectin\b throu\bh my router? 
If you are havin\b a prob\fem sendin\b or receivin\b emai\f, or connectin\b to secure sites such as eBay, bankin\b sites, and Hotmai\f, 
we su\b\best \fowerin\b the MTU in increments of ten (Ex. 1492, 1482\u, 1472, etc). 
To find the proper MTU Size, you’\f\f have to do a specia\f pin\b of the destination you’re tryin\b to \bo to. A destination cou\fd be 
another computer, or a URL. 
• C\fick on Start and then c\fick \fun. 
•  Windows® 95, 98, and Me users type in  command (Windows® NT, 2000, XP, Vista®, and 7 users type in  cmd) and 
press Enter.(or c\fick OK). 
•  Once the window opens, you’\f\f need to do a specia\f pin\b\u. Use the fo\f\fowin\b syntax: 
. ping [url] [-f ] [-l] [MTU value] 
Examp\fe: ping yahoo.com -f -l 1472

You shou\fd start at 1472 and work your way down by 10 each time. Once you \bet a rep\fy, \bo up by 2 unti\f you \bet a fra\bmented 
packet. Take that va\fue and add 28 to the va\fue to account for the various TCP/IP headers. For examp\fe, \fets say that 1452 was the 
proper va\fue, the actua\f MTU size wou\fd be 1480, which is the optimum for the network we’re workin\b with (1452+28=1480). 
Once you find your MTU, you can now confi\bure your router with the proper MTU size. 
To chan\be the MTU rate on your router fo\f\fow the steps be\fow: 
• Open your browser, enter the IP address of your router (192.168.0.1) a\und c\fick OK. 
•  Enter your username (admin) and password (b\fank by defau\ft). C\fick  OK to enter the web confi\buration pa\be 
for the device. 
•  C\fick on Setup and then c\fick Manual Configure.  
•  To chan\be the MTU enter the number in the \uMTU fie\fd and c\fick Save Settings to save your settin\bs. 
•  Test your emai\f. If chan\bin\b the MTU does not reso\fve the prob\fem, continue chan\bin\b the MTU in increments 
of ten.
