How do I increase the wireless security of my BT Business Hub 2700/2701?

BT Business HubsTo do this you'll need to configure your hub a little. We've listed the steps you can take in order of ease and how much impact they'll have. We'd definitely recommend the first 3 as they're very simple to do - just as long as you remember your new wireless key and network name.



Use WPA2 or WPA encryption

When the BT Business Hub 2 came out many computers and wireless adapters didn't support this standard. Now it's very likely your device or wireless adapter will.

To enable WPA2 or WPA encryption:

  1. Open your web browser, enter 192.168.1.254 and press the ENTER key.
  2. Click on the Settings tab.
  3. Click on the LAN tab, which appears below the Settings tab.
  4. Click on the Wireless link, which appears below and to the left of the LAN tab.
  5. Look for the Security section:

  6. From the Authentication Type drop-down list:

    • If all your devices support WPA2, select WPA2-PSK.
    • If some of your devices support WPA2 and some support WPA, select WPA-PSK and WPA2-PSK.
    • If none of your devices support WPA2, but they all support WPA, select WPA-PSK.
  7. Scroll to the bottom of the page and click on the Save button. You may be asked to enter your Hub password. If you haven't changed it, your password is the same as the serial number on the bottom of your Fibre Hub.
  8. Reconnect your wireless devices, using the encryption key printed on the System label on your Hub.

Select a new wireless security key or passphrase

The preset wireless security key is printed on the label on the bottom or back of your Hub. We strongly recommend that you change this to a passphrase of your choosing.

If you use WPA / WPA2, your passphrase should be made up of a mix of letters (upper and lower case), numbers and punctuation, unique and difficult to guess.

If you use WEP, your security key will be ten characters long, made up of a mix of numbers and the letters A-F. You should choose one that is unique and difficult to guess.

To select your own security key or passphrase:

  1. Go to your Hub's security settings, as detailed in Use WPA or WPA2 encryption above.
  2. Scroll down below the Hub diagram and check the Use custom encryption key box.
  3. Enter your security key or passphrase:

  4. Click on the Save button in the lower right of the screen. You may be asked to enter your Hub password. If you haven't changed it, your password is the same as the serial number on the bottom of your Fibre Hub.
  5. Reconnect any devices you wish to use to access the Internet wirelessly, supplying the same security key or passphrase.

Change your wireless network name (SSID)

This makes it a lot more difficult for someone to work out what type of hub you're using. This can make it much more difficult to hack. When choosing a new SSID, we recommend that you avoid anything that could identify it with your company. Avoid, for example, your company name or location.

To change your SSID:

  1. Go to your Hub's security settings, as detailed in Use WPA2 or WPA encryption above.
  2. Scroll to the Network section.
  3. In the Network Name (SSID) field, enter a new name. You may be asked to enter your Hub password. If you haven't changed it, your password is the same as the serial number on the bottom of your Fibre Hub.
  4. Scroll to the bottom of the page and click on the Save button.
  5. Reconnect any devices that were previously connected to the new network name. If you have already disabled the broadcast of the name, you will need to enter the new name of your network manually on any devices that you wish to connect to your Hub.

Disable the broadcast of your wireless network name (SSID)

Wireless network devices automatically broadcast certain information, including the network name (SSID). Unauthorised users can use this to find and connect to your network.

You can disable the broadcast of your SSID, which will help to hide your network from casual browsing. Anyone who wishes to connect to your network will then have to enter the network name manually. This step is especially effective when combined with the Change your wireless network name (SSID) step above.

To disable broadcast of your SSID:

  1. Go to your Hub's security settings, as detailed in Use WPA2 or WPA encryption above.
  2. Scroll to the Network section.
  3. Uncheck the SSID Broadcast box.
  4. Scroll to the bottom of the page and click on the Save button. You may be asked to enter your Hub password. If you haven't changed it, your password is the same as the serial number on the bottom of your Fibre Hub.

Set up MAC (Media Access Control) address filtering

This step is pretty advanced and can cause problems accessing your hub in future. As a rule of thumb, if you're not familiar with how to find out your device's MAC address we'd recommend not doing this step unless you're extremely concerned about security.

Every wireless and wired network device has a unique identifier called a MAC address. Your BT Business Hub reports which devices are connected according to their MAC addresses. By setting up MAC address filtering, you can choose which devices are allowed to access your Hub and which are not.

To manage your MAC addresses:

  1. Go to your Hub's security settings, as detailed in Use WPA2 or WPA encryption above
  2. Scroll to the bottom of the page.
  3. Click on the Edit Blocked/Allowed list link.
  4. Check the Enable MAC filtering box. Devices which have already connected are listed in the Allowed Devices list.
  5. To disallow a listed device, select it and click on the >> button.
    To add a device which is not listed, enter its MAC address in the Enter MAC address field and click on the Add to List button:

  6. Scroll to the bottom of the page and click on the Save button. You may be asked to enter your Hub password. If you haven't changed it, your password is the same as the serial number on the bottom of your Fibre Hub.
  7. Reconnect any devices you wish to use to access the Internet wirelessly.
