Learn how to diagnose or solve your Wi-Fi coverage issues

What is Wi-Fi?

Wi-Fi is technology that connects your personal devices, such as your tablet, smartphone or laptop, to the Internet without the need of a physical wired connection. This network technology transmits radio signals to and from your modem so that you can browse webpages, stream videos or play online games.


Why is Wi-Fi important?

When connecting by Wi-Fi, you benefit from the freedom and convenience of accessing the Internet throughout your home on Wi-Fi enabled devices, such as tablets or smartphones, that do not have wired connections. You and your family can also benefit from connecting to shared devices, such as your home printer, throughout your home.

What are some factors that affect Wi-Fi?

Here are some factors that affect your Wi-Fi performance:

Your home

When listening to music on the radio, the sound quality is not only dependent on how close you are to the radio but also on the number of walls the sound must pass through. Wi-Fi acts in a similar way. In order for Wi-Fi signals to travel from your modem to where you are using your device, it must pass through your walls and floors. Building materials like concrete and brick will reduce your Wi-Fi signal strength.


Your neighbours

Wi-Fi signals operate only on certain radio frequencies. Congestion on these frequencies are problematic because of high density living. Wi-Fi networks can become overcrowded, just like traffic on highways. The number of neighbouring Wi-Fi networks around your home can have an impact on your Wi-Fi performance.

Your devices

The number of devices, the age of your devices and what you do on your devices are all factors that affect your Wi-Fi performance. Wi-Fi technology allows for your modem to communicate with one device at a time.

If you have multiple Wi-Fi devices operating at the same time, each device must wait their turn to communicate. Some older tablets and smartphones communicate at a slower rate and can slow down your entire Wi-Fi network.

Like using the water from the same pipe to run the dishwasher, take a shower and care for your lawn, Wi-Fi bandwidth is shared amongst all your devices. Some applications, like uploading large files to your cloud storage, are bandwidth intensive and will hog more of the Wi-Fi network, leaving less available for the rest of your other devices.

In addition, other personal devices in your home emit disruptors to your Wi-Fi network because they operate on the same radio frequency as your Wi-Fi signals. A few examples include microwaves, baby monitors, cordless phones and wireless speaker systems.
