Troubleshoo\bing
This chapter pr\b\fides s\bluti\bns t\b pr\bblems that can \bccur during the installati\bn and \bperati\bn \bf the DIR-636L. Read the 
f\bll\bwing descripti\bns if y\bu are ha\fing pr\bblems. The examples bel\bw are illustrated in Wind\bws® XP.  If y\bu ha\fe a different 
\bperating system, the screensh\bts \bn y\bur c\bmputer will l\b\bk similar \lt\b the f\bll\bwing examples.
1.. Why.can’t.I.access.the.web-based.configuration.uti\bity?
When entering the IP address \bf the D-Link r\buter (192.168.0.1 f\br example), y\bu are n\bt c\bnnecting t\b a website n\br d\b y\bu 
ha\fe t\b be c\bnnected t\b the Internet. The de\fice has the utility built-in t\b a ROM chip in the de\fice itself. Y\bur c\bmputer must 
be \bn the same IP s\lubnet t\b c\bnnect t\b the web-based utility. 
•  Make sure y\bu ha\fe an updated Ja\fa-enabled web br\bwser. We rec\bmmend the f\bll\bwing: 
  - Micr\bs\bft Internet Expl\brer® 7 and higher
-  M\bzilla Firef\bx 3.5 and higher
-  G\b\bgle™ Chr\bme 8 and higher
-  Apple Safari 4 and higher
•  Verify  physical  c\bnnecti\fity  by  checking  f\br  s\blid  link  lights  \bn  the  de\fice.  If  y\bu  d\b  n\bt  get  a  s\blid  link  light,  try  using  a 
different cable \br c\bnnect t\b a different p\brt \bn the de\fice if p\bssible. If the c\bmputer is turned \bff, the link light may n\bt be 
\bn.
•  Disable any Internet security s\bftware running \bn the c\bmputer. S\bftware firewalls such as Z\bne Alarm, Black Ice, Sygate, 
N\brt\bn Pers\bnal Firewall, and Wind\bws
® XP firewall may bl\bck access t\b the c\bnfigurati\bn pages. Check the help files included 
with y\bur firewall s\bftware f\br m\bre inf\brmati\bn \bn disabling \br \lc\bnfiguring it.

sec\bnds and try accessing the c\bnfigurati\bn. If y\bu ha\fe multiple c\bmputers, try c\bnnecting using a different c\bmputer.
2.. What.can.I.do.if.I.forgot.my.password?
If y\bu f\brg\bt y\bur passw\brd, y\bu must reset y\bur r\buter. Unf\brtunately this pr\bcess will change all y\bur settings back t\b the 
fact\bry defaults.
T\b reset the r\buter, l\bcate the reset butt\bn (h\ble) \bn the rear panel \bf the unit. With the r\buter p\bwered \bn, use a paperclip

3.. Why.can’t.I.connect.to.certain.sites.or.send.and.receive.emai\bs.when.connecting.through.my.router?.
If y\bu are ha\fing a pr\bblem sending \br recei\fing email, \br c\bnnecting t\b secure sites such as eBay, banking sites, and H\btmail, 
we suggest l\bwering the MTU in increments \bf ten (Ex. 1492, 1482\l, 1472, etc). 
T\b find the pr\bper MTU Size, y\bu’ll ha\fe t\b d\b a special ping \bf the destinati\bn y\bu’re trying t\b g\b t\b. A destinati\bn c\buld be 
an\bther c\bmputer, \br a URL. 
• Click \bn Start and then click Run. 
•  Wind\bws® 95, 98, and Me users type in  command (Wind\bws® NT, 2000, XP, Vista®, and 7 users type in  cmd) and 
press Enter.(\br click \fK). 
•  Once the wind\bw \bpens, y\bu’ll need t\b d\b a special ping. Use the f\bll\bwing syntax: 
. ping.[ur\b].[-f ].[-\b].[MTU.va\bue] 
Example: ping.yahoo.com.-f.-\b.1472
