Numerous wireless consumer electronic devices rely on technologies such as Wi-Fi, Global Positioning Systems (GPS) and Bluetooth. License-exempt wireless devices, including computers, gaming consoles, phones, remote controls, and speakers, must meet and be certified according to ISED standards. These standards ensure that the devices can operate without causing interference with one another.
However, the use of the radio spectrum varies across different regions worldwide. As a result, certain areas have different standards and allocate different parts of the spectrum for various purposes. Interference issues can occur when devices not certified by ISED are used in Canada.
Wireless equipment certified for use in Canada will have an IC (Industry Canada) number displayed on its label. Sometimes, the IC number may also be found in the device's manual.
1. Troubleshooting Interference
Check your equipment setup
For Wi-Fi enabled devices such as personal computers and gaming consoles, interference or connectivity issues may occur if your device is not set up correctly.
To check your setup, first turn your device completely off and then back on again, then attempt to reconnect it. Follow any instructions and troubleshooting guides from the manufacturer or service provider, and make sure the devices use the latest updates for the operating system, drivers, and firmware from the manufacturer.
If that does not work, try moving the device closer to the Wi-Fi router you are attempting to connect to.
Check if other Wi-Fi or Bluetooth devices can connect and function properly. If other devices are working as expected, the issue lies with the device that cannot connect.
If problems continue, contact your Internet Service Provider (ISP) for assistance.
Check available Wi-Fi networks
Use your phone or computer to check if other Wi-Fi networks or Bluetooth devices are available to connect. You should see multiple Wi-Fi networks available if you live in a populated area. If you do not, that may be a sign of external interference.
Talk to your neighbours and see if they are experiencing the same issue. You can also walk around your neighbourhood with your phone and see which areas you cannot pick up any Wi-Fi networks in.
Try a different Wi-Fi band
Trying different Wi-Fi bands can significantly improve your wireless network's performance. The most commonly used Wi-Fi bands are 2.4 GHz, 5 GHz, and 6GHz.
Smartphone apps are available to help you identify the best Wi-Fi channel to minimize interference.
Keep in mind, however, that these tools reflect the current wireless environment, which is constantly changing.
To adjust Wi-Fi bands, you'll need to access your router's settings:
- Open a web browser and enter your router's IP address
- Log in using your router's username and password
- Navigate to Wi-Fi settings, wireless settings, or a similarly named section
- Most modern routers allow you to enable or disable the 2.4 GHz, 5 GHz, and 6 GHz bands individually If you are experiencing interference on 2.4 GHz, try switching to 5 GHz or 6GHz.
2. Testing for interference
Testing for internal interference
To determine whether the source of interference is within your home or workplace, you can perform a circuit breaker test. The interference should cease when you turn off the circuit connected to the faulty equipment. If it does not, the interference is likely external.
Testing for external interference
If you think the interference is caused by an external source, and your affected device is portable, you can walk around your home or workplace to identify the specific areas where the interference occurs. This might help you locate the possible source of the interference.
If your GPS device is not functioning properly, try moving away from buildings or structures that might be blocking the GPS signal. GPS signals are weak, and devices that receive GPS signals usually require an unobstructed view of the sky for optimal performance. If multiple GPS devices in your area are also experiencing issues, this may suggest the presence of external interference.
If one of your vehicle's key fobs is not working, but your spare key fob does work, start by replacing the battery in the malfunctioning fob. If that doesn't resolve the issue, try using the key fob in a different location, away from your neighbourhood. If the key fob starts working, then the problem is likely external and not related to the fob itself. The source of the interference could be from a nearby car with a defective remote starter, or other radio transmitters. Consult a qualified mechanic or locksmith to resolve the problem.
3. Reporting interference
ISED does not investigate general household or business interference. Instead, it focuses on investigating interference that impacts public safety communications.
If you believe radio interference is severely impacting these critical communications, you should contact your nearest ISED Spectrum Management district office. They will review the information you provide, determine whether the interference is harmful, and take appropriate action to identify and resolve the issue.
If you are a public safety agency (such as police, fire, emergency medical services, the Canadian Coast Guard, or the Department of National Defence – Search and Rescue), please refer to CPC-3-13-03 — Interference Resolution Services on a 24/7 Basis for Public Safety Agencies for important additional information.
