SmartRG 505N: Changing Your Wireless 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 http://192.168.1.1
  3. Click on the Basic Configuration link which can be found in the top right corner
  4. You should now be prompted to enter a User Name and Password, by default these are:

    User Name: admin
    Password: admin

  5. Click on the Wireless link found on the left side of the page
  6. Click on the Advanced link
  7. Set the Channel field to either 1, 6, or 11
  8. Click Apply/Save
  9. 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.
