your router and click

Connect

It may take 20-30 seconds to connect to the wireless network. If the

connection fails, please verify that the security settings are correct. The

key or passphrase must be exactly the same as the one on the wireless

router.

Troubleshooting

This chapter provides solutions to problems that may occur during the installation and operation of the DIR-859.

1. Why can’t I access the web-based conﬁguration utility?

When entering the IP address of the D-Link router (

192.168.0.1

for example), you are not connecting to a website, nor do you

have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must

be on the same IP subnet to connect to the web-based utility.

• Make sure you have an updated Java-enabled web browser. We recommend the following:

- Explorer® 8 or higher

- Firefox®

- Chrome™

- Safari® 5 or higher

• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a

diﬀerent cable or connecting to a diﬀerent port on the device. If the computer is turned oﬀ, the link light may not be on.

• Disable any Internet security software running on the computer. Software ﬁrewalls such as Zone Alarm, Black Ice, Sygate,

and Norton Personal Firewall may block access to the conﬁguration pages. Check the help ﬁles included with your ﬁrewall

software for more information on disabling or conﬁguring it.

• Conﬁgure your Internet settings:

• Go to

Start

>

Settings

>

Control Panel

. Double-click the

Internet Options

Icon. From the

Security

tab, click

the button to restore the settings to their defaults.

• Click the

Connection

tab and set the dial-up option to

Never Dial a Connection

. Click the

LAN Settings

button.

Make sure nothing is checked. Click

OK

.

• Go to the

Advanced

tab and click the button to restore these settings to their defaults. Click

OK

three times.

• Close your web browser (if open) and open it.

•

Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This

should open the login page for your web management.

• If you still cannot access the conﬁguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30

seconds and try accessing the conﬁguration. If you have multiple computers, try connecting using a diﬀerent computer.

2. How do I connect my wireless devices to the DIR-859 router?

1. Open your wireless network utility that displays available wireless networks.

2. Select the Wi-Fi Network name you assigned during the Setup Wizard and connect.

Note:

If you did not run the Setup Wizard or you reset the router to its default settings, refer to the Wi-Fi Conﬁguration Card included

for the default Wi-Fi Network Name and Wi-Fi Password.

You can also connect wireless devices to the DIR-859 router using WPS:

1. Press the WPS button on the DIR-859 for a minimum of three seconds, or until the Power LED starts to blink green.

2. Within one minute press the WPS button on your wireless device.

3. Allow up to two minutes to connect.

Note:

Some devices may require you to log in to a utility to start the WPS process. Refer to the user manual for the device you want to

connect to the router if you do not know how to start the WPS process.

3. What can I do if I forget my password?

If you forget your password, you must reset your router. Unfortunately, this process

will change all your settings back to the factory defaults.

To reset the router, locate the reset button (hole) on the bottom of the unit. With the

router powered on, use an unfolded paper clip to press and hold the button down

for about 10 seconds. Release the button and the router will go through its reboot

process. Wait about 30 seconds to access the router.

5. Why can’t I connect to certain sites or send and receive e-mails when connecting through my router?

If you are having a problem sending or receiving e-mail, or connecting to secure sites such as eBay and banking sites, we

suggest lowering the MTU in increments of ten (e.g., 1492, 1482, 1472, etc).

To ﬁnd the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be

another computer, or a URL.

• Click on

Start

and then click

Run

.

• Windows® 8, 7, and Vista® users type in

cmd

and press

Enter

(or click

OK

).

• Once the window opens, you’ll need to do a special ping.

Use the following syntax:

ping [url] [-f] [-l] [MTU value]

Example:

ping yahoo.com -f -l 1472

4. Can I connect the DIR-859 to an existing router?

We recommend that you replace your existing router with the DIR-859 instead of using both. If your modem is a combo router,

you may want to contact your ISP or review the manufacturer's user guide so you can put the combo router into

Bridge

mode,

which will turn oﬀ the device's NAT functions.

You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented

packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the

proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).

Once you ﬁnd your MTU, you can now conﬁgure your router with the proper MTU size.

To change the MTU rate on your router follow the steps below:

• Open your browser, enter the IP address of your router (

192.168.0.1

) and click

OK

.

• Enter your username (

admin

) and password (blank by default). Click

OK

to enter the web conﬁguration page

for the device.

• Click on

Setup

and then click

Manual Conﬁgure

.

• To change the MTU, enter the number in the MTU ﬁeld and click

Save Settings

to save your settings.

• Test your e-mail. If changing the MTU does not resolve the problem, continue changing the MTU in increments

of ten.
