Updating your Wireless Network Name and Password


  • Your SmartRG 505N modem/router, plugged in and powered on
  • A computer, tablet, phone, or other device with internet browsing software installed – Internet Explorer, Firefox, Chrome, and Safari, are typical examples
  • A connection between your device and the SmartRG 505N - We recommend doing this by connecting an Ethernet cord from your device to one of the LAN ports on the back of the SmartRG 505N, but you can also do this using WiFi.


  1. Open a Web Browser and go to;
  2. You will then be prompted to enter a User Name & Password, by default these are:
    • User Name: admin
    • Password: admin
  3. Click "Wireless" which will be the third tab from the top on the left side of the page:
  4. Ensure "Enable Wireless" is checked. You may now change your SSID (i.e. your Network name) to anything you like.
  5. Click the "Security" tab on the left hand side of the screen.
  6. Ensure that your Network Authentication is set to "Mixed WPA2/WPA-PSK"
  7. Uncheck "Use base MAC address as WPA/WAPI passphrase".
  8. You may now change your WPA/WAPI passphrase (i.e. your Password) to your choice.
  9. Click "Apply/Save" and you've successfully changed your Network Name and Password!


Changing your Wireless Network Channel

Have you received your new SmartRG SR505N modem but the wireless seems slow? Has your wireless always been fast, but it seems to have suddenly slowed down? You may be experiencing wireless congestion! Changing your wireless channel may help you to avoid this congestion and improve your speed. 

The following instructions will assist you in changing your wireless channel:

  1. Test your internet's speed using a computer that is connected to the modem by a wired connection. This ensures that the problem is actually with your wireless and not a problem with your internet connection in general.
  2. Open a Web Browser and go to the address
  3. You should now be prompted to enter a User Name and Password, by default these are:
    • User Name: admin
    • Password: admin
  4. Click on the Wireless link found on the left side of the page.
  5. Click on the Advanced link.
  6. Set the Channel field to either 1, 6, or 11.
  7. Click Apply/Save.
  8. Test your wireless speed again; if it is still slow, change the channel again and re-test.

There are 11 channels, why should I only use 1,6, or 11?
Channels in the 2.4Ghz spectrum overlap and interfere with the two channels on either side of them.

Channel 6 for example, actually spans across channels 4,5,6,7, and 8 while Channel 3 spans across channels 1, 2, 3, 4, and 5.

This means that if you were to select channel 3 because 1 and 6 are congested, you are now being interfered with by BOTH channel 1 AND channel 6. In short, if you attempt to avoid the congestion on 1, 6, or 11 by choosing a different channel, you are just putting yourself into a position of even greater interference and congestion.
