D-Link 2604B: setup guide

What you need to know before you set up

Before you can do anything, you’ll need to make sure your broadband connection is up and running. We’ll send you a text or email when it’s good to go.

Here’s a few tips to think about when you are getting everything working:

  • Your broadband will work best if your router’s connected to the master telephone socket. Avoid putting your router somewhere where air can’t get to it because it can become hot.
  • Things like thick walls and concrete floors can actually weaken your wireless signal. So put your router as close to where you’re going to use it as possible.
  • It’s best to leave your router on all the time if you can. Have a read of our broadband speed tips for more on why.
  • There’s more advice in our article on getting the best wi-fi signal.

Check that you've got the following items:

Make sure you've got everything

There will also be a microfilter, a quick install guide and a sticker to record your wireless security details. The wireless aerial is packed separately and you will need to attach this.

The user guide on the CD will help you use the D-Link 2640B's advanced features.

Microfilters already plugged in? Go to Connect your router and plug it in.

Plug a microfilter into each telephone socket you use in your property. If you had to unplug something you can plug it back into the Phone socket of the microfilter.

Phone sockets can be used by phones, alarm systems, fax machines and digital TV boxes, so make sure you don't miss anything out. Microfilters are essential for keeping your phone and Internet services from interfering with each other. Without microfilters you'll see poor speeds and connection drops.

  • You can use a microfilter before or after an extension lead, but not both
  • You can connect two devices to one microfilter if you use a phone adapter
  • If you need more microfilters, you can get them from most electrical stores and supermarkets
  • Don't plug a microfilter into the socket of another microfilter
  1. Plug the grey telephone cable into the microfilter socket marked DSL.
  2. Plug the other end of the grey telephone cable into the DSL socket on the back of the router.
  3. Connect the power adapter and switch the router on with the power button at the back.
  4. The power light will initially be red and the DSL light will flash. Wait until they stop flashing and turn solid green before proceeding to the next section.

Wireless connection

To connect wirelessly, follow the instructions included with your computer, phone or other device to connect to your router via wi-fi. If you need help with this, please see our Wireless connection guides.

Wireless security is not enabled on this router as standard.

  • If you've recently reset your router, the wireless network name will be dlink and there'll be no password.
  • The setup steps below will help you set up wireless security. If you've followed these steps before, use the new details you set up to connect wirelessly

Wired connection

If you're using the Ethernet cable connect it to any of the four yellow Ethernet sockets on the back of your router.

Connect the other end of the Ethernet cable to the Ethernet socket on your computer or laptop.

Once your router is installed, you'll need to configure it.

1. Open your web browser and type 192.168.1.1 into the address bar.

2. A login window will appear, enter the username and password and click 'Log in'. By default the details are:

  • Username: admin
  • Password: admin

3. Once you're logged in, click 'Setup Wizard'.

4. Click next and you'll be asked to change your router password. Enter the current password (default is admin) and the new password, confirm it and click next:

Change Password

5. On the Select Internet Connection Type screen choose United Kingdom as the Country and Others as the ISP Provider and click 'Next':

Connection Settings 1

6. Enter your broadband username and password, confirm the password and click 'Next':

Connection Settings 2

7. Finally click 'Restart' to reboot the router:

Configure wireless security

1. Open your web browser and browse to 192.168.1.1 and log in. The default username and password are both admin.

2. Click 'Wireless Setup' on the left side of the 'Setup' page to access the wireless settings and click the 'Secure My Wireless Network' button:

3. On this screen you can change or hide the 'Wireless Network Name'. If you find that your wireless signal is poor changing the 'Wireless Channel' may improve this.

By default encryption is set to none, we recommend changing this to WPA-PSK as this is the most secure method. Choose a WPA Key and enter it in the box below. A WPA Key is like a password. Once set you'll need to use this with any computer or games console you want to connect to your wireless network.

Once you've finished click 'Apply Settings':

Wireless Settings

4. Once the settings are applied you'll need to connect to the router again.

5. Use your wireless adapter's connection utility to scan for available networks. Your D-Link DSL 2640B will show up as the 'Wireless Network Name' you entered above (or dlink if you left it unchanged). Select your network and press connect:

Searching for Wireless network - Windows

6. You'll be promted for the password you created in step 3.

Enter, confirm this and press 'Connect' to log on to your wireless network:
