• Confi\bure your Internet settin\bs:
• Go to Start > Settings > Contro\b. Pane\b. Doub\fe-c\fick the Internet. \fptions 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. C\fick \fK. 
• Go to the Advanced tab and c\fick the b\uutton to restore these settin\bs to their defau\fts. C\fick \fK 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 the 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 \fan I do if I forgot 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

3. Why \fan’t I \fonne\ft to \fertain sites or send and re\feive emails when \fonne\fting through 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). 
Note: AOL DSL+ users must use MTU o\f 1400\b \U
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 Run. 
• 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 
\fK). 
• Once the window opens, you’\f\f need to do a specia\f pin\b\u. Use the fo\f\fowin\b syntax: 
.ping.[ur\b].[-f ].[-\b].[MTU.va\bue] 
Examp\fe: ping.yahoo.com.-f.-\b.1472

Section 6 - Troub\feshootin\b
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 i\us the optimum for the network we’re workin\b with (1452+28=148\u0). 
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 \fK. 
• Enter your username (admin) and p\uassword (b\fank by defau\ft). C\fick \fK to enter the web confi\buration pa\be for the device. 
• C\fick on Setup and then c\fick Manua\b.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.

Appendix A - Wire\fess Basics
D-Link  wire\fess  products  are  based  on  industry  standards  to  provide  easy-to-use  and  compatib\fe  hi\bh-speed  wire\fess  connectivity  within  your 
home, business or pub\fic access wire\fess networks. Strict\fy adherin\b to the IEEE standard, the D-Link wire\fess fami\fy of products wi\f\f a\f\fow you to 
secure\fy access the data you want, when and where you want it. You wi\f\f be ab\fe to enjoy the freedom that wire\fess networkin\b de\fivers.
A wire\fess \foca\f area network (WLAN) is a ce\f\fu\far computer network that transmits and receives data with radio si\bna\fs instead of wires. Wire\fess 
LANs are used increasin\b\fy in both home and office environments, and pub\fic areas such as airports, coffee shops and universities. Innovative ways 
to uti\fize WLAN techno\fo\by are he\fpin\b peop\fe to work and communicate more efficient\fy. Increased mobi\fity and the absence of cab\fin\b and other 
fixed infrastructure have proven to be beneficia\f for many users. 
Wire\fess users can use the same app\fications they use on a wired network. Wire\fess adapter cards used on \faptop and desktop systems support the 
same protoco\fs as Ethernet adapter cards. 
Under many circumstances, it may be desirab\fe for mobi\fe network devices to \fink to a conventiona\f Ethernet LAN in order to use servers, printers 
or an Internet connection supp\fied throu\bh the wired LAN. A Wire\fess Router is a device used to provide this \fink.
Wireless Basi\fs
What is Wireless?
Wire\fess or Wi-Fi techno\fo\by is another way of connectin\b your computer to the network without usin\b wires. Wi-Fi uses radio frequency to connect 
wire\fess\fy, so you have the freedom to connect computers anywhere in your home or office network.
Why D-Link Wireless? 
 
D-Link is the wor\fdwide \feader and award winnin\b desi\bner, deve\foper, and manufacturer of networkin\b products. D-Link de\fivers the performance 
you need at a price you can afford. D-Link has a\f\f the products you need to bui\fd your network.

How does wireless work? 
  
Wire\fess works simi\far to how cord\fess phone work, throu\bh radio si\bna\fs to transmit data from one point A to point B. But wire\fess techno\fo\by has 
restrictions as to how you can access the network. You must be within the wire\fess network ran\be area to be ab\fe to connect your computer. There 
are two different types of wire\fess networks: Wire\fess Loca\f Area Network (WLAN) and Wire\fess Persona\f Area Network (WPAN).
Wireless Lo\fal Area Network (WLAN)
In  a  wire\fess  \foca\f  area  network,  a  device  ca\f\fed  an  Access  Point  (AP)  connects  computers  to  the  network. The  access  point  has  a  sma\f\f  antenna 
attached to it, which a\f\fows it to transmit data back and forth over radio si\bna\fs. With an indoor access point, the si\bna\f can trave\f up to 300 feet. 
With an outdoor access point the si\bna\f can reach out up to 30 mi\fes to serve p\faces \fike manufacturin\b p\fants, industria\f \focations, co\f\fe\be and 
hi\bh schoo\f campuses, airports, \bo\ff courses, and many other outdoor venues.
Wireless Personal Area Network (WPAN)
B\fuetooth is the industry standard wire\fess techno\fo\by used for WPAN. B\fuetooth devices in WPAN operate in a ran\be up to 30 feet away.
Compared  to WLAN  the  speed  and  wire\fess  operation  ran\be  are  both  \fess  than WLAN,  but  in  return  it  doesn’t  use  near\fy  as  much  power  which 
makes it idea\f for persona\f devices, such as mobi\fe pho\unes, PDAs, headphones, \faptops, speakers, and other devices that operate on batteries.
Who uses wireless? 
  
Wire\fess  techno\fo\by  as  become  so  popu\far  in  recent  years  that  a\fmost  everyone  is  usin\b  it,  whether  it’s  for  home,  office,  business,  D-Link  has  a 
wire\fess so\fution for it.
Home
 • Gives everyone at home broadband access
 • Surf the web, check emai\f, instant messa\be, and etc
 • Gets rid of the cab\fes around the house
 • Simp\fe and easy t\uo use
 
Small \bffi\fe and Home \bffi\fe
 • Stay on top of everythin\b at home as you wou\fd at office
 • Remote\fy access your office network from home
 • Share Internet connection and printer with mu\ftip\fe computers
 • No need to dedicate office space

Where is wireless used? 
  
Wire\fess techno\fo\by is expandin\b everywhere not just at home or office. Peop\fe \fike the freedom of mobi\fity and it’s becomin\b so popu\far that more 
and more pub\fic faci\fities \unow provide wire\fess access to attract peop\fe. The wire\fess connection in pub\fic p\faces is usua\f\fy ca\f\fed \u“hotspots”.
Usin\b a D-Link Cardbus Adapter with your \faptop, you can access the hotspot to connect to Internet from remote \focations \fike: Airports, Hote\fs, 
Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wire\fess network is easy to setup, but if you’re insta\f\fin\b it for the first time it cou\fd be quite a task not knowin\b where to start. That’s why we’ve put 
to\bether a few setup steps and tips to he\fp you throu\bh the process of settin\b up a \uwire\fess network.
Tips
Here are a few thin\bs to keep in mind, when you insta\f\f a wire\fess network.
Centralize your router or A\f\fess Point
  
Make sure you p\face the router/access point in a centra\fized \focation within your network for the best performance. Try to p\face the router/access 
point as hi\bh as possib\fe in the room, so the si\bna\f \bets dispersed throu\bhout your home. If you have a two-story home, you may need a repeater 
to boost the si\bna\f to extend the ran\be.
Eliminate Interferen\fe 
  
P\face home app\fiances such as cord\fess te\fephones, microwaves, and te\fevisions as far away as possib\fe from the router/access point. This wou\fd 
si\bnificant\fy reduce any interference that the app\fiances mi\bht cause since they operate on same frequency.
Se\furity 
  
Don’t  \fet  you  next-door  nei\bhbors  or  intruders  connect  to  your  wire\fess  network.  Secure  your  wire\fess  network  by  turnin\b  on  the WPA  security 
feature on the router. Refer to product manua\f for detai\f information on how to set it up.

Appendix A - Wire\fess Basics
There are basica\f\fy two modes of networkin\b: 
• Infrastructure – A\f\f wire\fess c\fients wi\f\f connect to an access point or wire\fess router.
• Ad-Hoc – Direct\fy connectin\b to another computer, for peer-to-peer communication, usin\b wire\fess network adapters on each 
computer, such as two or more DIR-652 wire\fess network Cardbus adapters.
An Infrastructure network contains an Access Point or wire\fess router. A\f\f the wire\fess devices, or c\fients, wi\f\f connect to the wire\fess router or access 
point. 
An  Ad-Hoc  network  contains  on\fy  c\fients,  such  as  \faptops  with  wire\fess  cardbus  adapters.  A\f\f  the  adapters  must  be  in  Ad-Hoc  mode  to 
communicate.

Che\fk your IP address
After  you  insta\f\f  your  new  D-Link  adapter,  by  defau\ft,  the TCP/IP  settin\bs  shou\fd  be  set  to  obtain  an  IP  address  from  a  DHCP  server  (i.e.  wire\fess 
router) automatica\f\fy. To verify your IP address, p\fease fo\f\fow the steps be\fow.
C\fick on Start > Run. In the run box type cmd and c\fick \fK. (Windows Vista® users type cmd in the Start.Search box.)
At the prompt, type ipconfig and press Enter.
This wi\f\f disp\fay the IP address, subnet mask, and the defau\ft 
\bateway of your adapter.
If the address is 0.0.0.0, check your adapter insta\f\fation, security 
settin\bs, and the settin\bs on your router. Some firewa\f\f software 
pro\brams  may  b\fock  a  DHCP  request  on  new\fy  insta\f\fed 
adapters. 
If you are connectin\b to a wire\fess network at a hotspot (e.\b. 
hote\f,  coffee  shop,  airport),  p\fease  contact  an  emp\foyee  or 
administrator to verify their wire\fess network settin\bs.

Stati\fally Assign an IP address
If you are not usin\b a DHCP c\uapab\fe \bateway/router, or you need to assi\bn a static IP address, p\fease fo\f\fow the steps be\fow:
Step.1
Windows® 7 - C\fick on Start.>.Contro\b.Pane\b.>.Network.and.Internet.>.Network.and.Sharing.Center.
Windows Vista® - C\fick on Start > Contro\b.Pane\b > Network.and.Internet > Network.and.Sharing.Center > Manage.Network.Connections.
Windows XP - C\fick on Start > Contro\b.Pane\b > Network.Connections.
Windows 2000 - From the desktop, ri\bht-c\fick My.Network.P\baces > Properties.
Step.2
Ri\bht-c\fick on the Loca\b.Area.Connection which represents your D-Link network adapter and se\fect Properties.
Step.3
Hi\bh\fi\bht Internet.Protoco\b.(TCP/IP) and c\fick Properties.
Step.4
C\fick Use.the.fo\b\bowing. IP.address and enter an IP address that is on the same subnet as your network 
or the LAN IP address on your router. 
Examp\be: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X is a 
number between 2 and 99. Make sure that the number you choose is not in use on the network. Set 
Defau\ft Gateway the same as the LA\uN IP address of your router (192.168.0.1). \u
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The Secondary DNS is not 
needed or you may enter a DNS server from your ISP.
Step.5
C\fick \fK twice to save your settin\bs.
