Checking for WiFi Interference

 

It is quite common for Wifi interference in the home or workplace to effect the speed of your internet service.

This is becoming an increasing problem for many people, so should be one of the first things to check when diagnosing speed issues. In order to determine the cause for this issue there are some basic steps to try before we look at other possible points of the network. This list will guide you through some tests you can do to rule out interference and other common problems.

 

The first step is to do a speed test using one of the Ezi-Web Speed Test servers

• Bundaberg – http://bberg-speedtest.ezi-web.com.au/
• Brisbane – http://bris-speedtest.ezi-web.com.au/

Take a note of what the test results are. These will be your benchmark for when changing settings or performing the below tests.

 

Verify if the problem is related to Wifi

Plug your computer directly to the router using a network cable, and turn off your Wifi connection. This is the easiest and most reliable method of ruling out Wifi interference.

Perform another speed test using the same server you did previously.

Its Better! ) If the speeds improve to what you would expect, there is a good change your problem if Wifi realted. The next step would be to look at the cause of WiFi interference, or changing the Wifi channel or frequency to work around it. 

No Change ) Since there was no change when connecting via a network cable, your problem is most likley not related to Wifi. Please see our other guides on how to diagnose your problem.

 

If it isn’t possible to connect to your router using a network cable, please have your WiFi enabled device as close as possible to the router and continue through the following steps.

 

 

Finding a solution to Wifi interference

Before proceeding, it is worth turning off your router for 5 minutes and then turn it back on. It’s common for consumer grade routers to need a restart every now and again, or after power fluctations. Also, the router (in is default state) will automatically select the best Wifi channel when turning on.

Test you speed again using the same server as previously to check for any improvement.

  • Turn off any other devices you may have (e.g. game consoles, mobile phones, Bluetooth devices, microwave if running etc.) This will reduce the possibility of interference. There has been many cases these devices causing problems, though mainly with the 2.5Ghz Wifi.
  • If you have a dual band router (2.4Ghz and 5Ghz WiFi) connect to the other frequency and test again. When viewing your Wifi list you will normally see two signals to select coming from your router. E.g.  Ezi-Web_xxxx  and Ezi-Web_xxx 5G.
  • The next step would be to change the Wifi channel. The router may not be selecting the best channel (frequency). We have guides on how to change the Wifi channels on most routers we supply. You can view these in the Support guides section of the help center.
