3..Why.can’t.I.connect.to.certain.sites.or.send.and.receive.emai\bs.when.connecting.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). 
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 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 \fK. 
• Enter your username (admin) and password (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 oth\uer 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.

What.is.Wire\bess?
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. Wire\bess? 
  
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.wire\bess.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).
Wire\bess.Loca\b.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 
as seen in the picture, 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.

Wire\bess.Persona\b.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 phones, PDAs, headphones, \faptops, speakers, and other 
devices that operate on batteries.
Who.uses.wire\bess?.
  
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.

Where.is.wire\bess.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 now 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.
Centra\bize.your.router.or.Access.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.
E\biminate.Interference 
  
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.

Appendix A - Wire\fess Basics
Security 
  
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 or WEP security feature on the router. Refer to product manua\f for detai\f information on how to set it up.
 
 
     
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-826L 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® 7/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\u\f\fed adapters.

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 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 add\uress on your router. 
Examp\fe: 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 the Defau\ft Gateway the same as the LAN IP address of your 
router (I.E. 192.168.0.1). 
Set  Primary  DNS  the  same  as  the  LAN  IP  address  of  your  router  (192.168.0.1).  The 
Secondary DNS is not needed\u or you may enter a DNS server from your ISP.
Step.5
C\fick \fK twice to save your settin\bs.
