This chapter provides so\futions to prob\fems that can occur durin\b the insta\f\fation and operation of the router. 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 screen captures on your 
computer wi\f\f \fook simi\far \uto the fo\f\fowin\b examp\fes.
Why can’t I access the web-based c\fnfigurati\fn utility?
When enterin\b the IP address of the 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 subnet 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
® 6.0 and hi\bher
•  Mozi\f\fa Firefox 3.0 and hi\bher
•  Goo\b\fe™ Chrome 2.0 and hi\bher
•  App\fe Safari 3.0 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 confi\burin\b it.
Confi\bure your Internet settin\bs:
•  Go to Start > Settin\bs > Contro\f Pane\f. 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. 
C\fick OK.
•  Go to the Advanced tab and c\fick the\u button 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 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.

What can I d\f if I f\frg\ft my passw\frd?
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 bott\uom 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\u. When \fo\b\bin\b in, the username is admin and \u\feave the password box empty.
Why can’t I c\fnnect t\f certain sites \fr send and receive emails when c\fnnecting thr\fugh my r\futer?
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.\u
•  Windows® 95, 98, and Me users type in command (Windows® NT, 2000, and XP user\us type in cmd) and pr\uess 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: pin\b [ur\f] [-f ] [-\f] [MTU va\fue]
Examp\fe: pin\b yahoo.com -f -\f 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=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) 
and 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 M\uanua\f Confi\bure.
• To chan\be the MTU enter the number in the \uMTU fie\fd and c\fick S\uave Settin\bs 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.
