Troubleshooting
This chapter provides so\futions to prob\fems that can occur durin\b the insta\f\fation and operation of the DIR-865L. 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.configuration.uti\bity?
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 > 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\u. 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 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.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  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\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 
   
						

							132D-Link DIR-865L User Manua\f
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.

Appendix A - Wire\fess Basics
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.
