Improving WiFi Signal and Changing Channels

This article will explain the best way to set up your modem to ensure its WiFi (wireless) network signal is as strong as possible.

Select one of the links below to jump to a query:

  • Put your modem in a clear, central place in your home. A typical indoor WiFi signal has a range of about 30 metres, but this distance can be reduced by a large amount of obstacles (e.g. walls, cupboards) between you and your modem.
     
  • If you have a larger area to cover, you may want to buy a WiFi signal extender from your local electronics store. This device will plug into a power outlet and relay your WiFi signal over a longer distance.
     
  • Place your modem on a desk or elevated shelf; WiFi signal travels better "downwards". A modem should never be placed on the floor as the ground causes a lot of signal interference.
     
  • Keep your modem away from any trees, plants, microwaves, metal objects and also any other devices that broadcast a WiFi signal. Try to avoid having these obstacles between you and your modem while you’re using the WiFi.

 

WiFi comes in a variety of modes/standards, which are WiFi signal technologies that were developed over the years. 

The most common WiFi mode is 802.11n, which has been around since 2009. However, the older 802.11g and 802.11b modes can have a greater range and stability, which is ideal if the structure of your home causes a lot of WiFi signal interference.

The downside is these modes have a lower throughput speed, but this shouldn't be noticeable on the vast majority of ADSL connections.

  • You can find steps that include accessing and changing the WiFi mode settings for modems purchased from iiNet in Troubleshooting WiFi Network for No Connection. Changing to a mode setting like 802.11g only or 802.11b only may improve your WiFi experience.

If you have a modem or router that wasn't purchased from iiNet, you'll need to log into its default gateway to change the WiFi settings. The layout of modem settings can vary greatly for each device, so please consult your modem's user manual or check the manufacturer's website for support information about changing the WiFi settings.

 

  1. Open the Command Prompt program. You’ll find this by typing “cmd” into your computer’s search bar. It can also be found in the Accessories folder in the All Programs list in the Start Menu.
     
  2. A black box with a flashing cursor will appear; this is the Command Prompt. Type “netsh wlan show all” and then hit the Enter key on your keyboard.
     

     
  3. A list of information for each WiFi network (SSID) detected by your computer's WiFi adapter will show up. Scroll through this list and take note of the channel being used by each network.
     

     
  4. The best channel for your WiFi is the one not being used by most other WiFi networks around you (e.g. the neighbours). For example, if most other WiFi networks are using channel 11, try using channel 1 or 6 in your modem's WiFi settings. Channels 1, 6 and 11 are the most ideal channels to use in Australia.

 

  1. Hold down the Option key on your keyboard and then click the Wireless icon in the top menu bar.
     
  2. You’ll see the WiFi network details for your current WiFi connection in the drop-down menu.
     

     
  3. To see the WiFi channels being used by other networks around you, hold down the Option key and then hover the cursor over the name of the network in the list. After a few seconds, a text box will appear next to the cursor with the details for that network, including the channel.
     
  4. Repeat step 3 for each WiFi network detected by your computer and take note of the channel being used by each network.
     
  5. The best channel for your WiFi is the one not being used by most other WiFi networks around you (e.g. the neighbours). For example, if most other WiFi networks are using channel 11, try using channel 1 or 6 in your modem's WiFi settings. Channels 1, 6 and 11 are the most ideal channels to use in Australia.
     

These instructions should work for modems purchased from iiNet. If you have a modem or router that wasn't purchased from iiNet, you'll need to log into its default gateway to change the WiFi settings. The layout of modem settings can vary greatly for each device, so please consult your modem's user manual or check the manufacturer's website for support information about changing the WiFi channel.

 

  1. On a computer or WiFi device that's connected to your modem, open your web browser and go to http://10.1.1.1
     
  2. Log in with the default username admin and default password admin. If you have changed these settings from the default, use your custom details instead.
     
  3. Click the Wireless panel on the dashboard.
     

     
  4. Select the desired channel from the Channel drop-down menu and then click Save to finish.
     

 

  1. On a computer or WiFi device that's connected to your modem, open your web browser and go to http://192.168.0.1
     
  2. Log in with the default username admin and default password password (note that a small number of customers may need to leave these fields blank instead) If you have changed these settings from the default, use your custom details instead.
     
  3. In the top menu bar, select Advanced.
     
  4. Select Wireless. On the Radio Settings page, go to the correct section depending on which WiFi network you are using - 2.4Ghz Radio or 5Ghz Radio.
     
  5. Select the desired channel from the Control Channel drop-down menu. The Cable Gateway Pro should show the results of an interference check on-screen.
     

 

Although screenshots have been taken using the HG532d, these instructions should also work for the VDSL Home Gateway (Huawei HG658) as the layout of their settings are very similar.

  1. On a computer/device that's connected to your modem via Ethernet (recommended) or WiFi, open your web browser and go to http://192.168.1.1
     
  2. Log in with the default username "admin" and default password “admin”. If you have changed your login details from the default, use your custom details instead.
     
  3. In the left-hand column, click Basic and then select WLAN.
     
  4. Select the desired channel from the Channel drop-down menu and then click Submit to finish.
     

 

Please note that these instructions will only work for the NetComm NB16WV-02 purchased from the iiNet Group.

  3. At the bottom of the page, click Switch to advanced view.
     
  4. Click Network Setup in the top menu bar and then select Wireless 2.4GHz from the drop-down menu. If you use the 5GHz network (check the network name (SSID) if you're not sure) then select Wireless 5GHz instead.
     
  5. Select the desired channel from the Channel drop-down menu and then click Save to finish.
