When it seems the Internet isn’t running as fast as it should, you might want to look into running a speed test. However, what you do before you run it can have huge effects on the results (not to mention, it might be the reason for the slowdown in the first place!).
To properly conduct a speed test:
Make sure you’ve deactivated or removed any other devices from your connection. If you have a wireless network, make sure all phones, laptops and gaming devices are off or disconnected from the network.
