Your maximum internet connection speed can be affected by several factors, including, but not limited to:
The age and specifications of your devices, such as your phone, laptop, Smart TV, and any adapters and dongles you might be using
The type of connection between your device and the router (e.g., Ethernet, Wi-Fi) you are using
The processing abilities of your devices (PC/laptop, tablet, smartphones, etc.)
The number of devices on your network and what they’re using the internet for, as internet speeds are shared among all devices on the network
The TELUS Internet service plan to which you are subscribed
These are only a few of the many reasons why one's Internet connection often does not achieve the theoretical maximum speed. Generally, Ethernet connections are faster and more reliable than Wi-Fi connections so, if possible, use that method of connection and a device supporting the maximum performance of your Internet service plan for the best results.
Remember, too, that some websites you visit may have slowness issues on their end, unrelated to your internet speed. Use the speedtest above to determine your systems' actual performance.
