While you’re at it, double-check to make sure your computer isn’t downloading something in the background. Make sure your Wi-Fi router is away from other electronic devices like cordless phones, and temporarily disconnect any other devices from your Wi-Fi network-after all, you don’t want another computer on your network to download a gigabyte worth of software updates while you run your tests. If you’re stuck using Wi-Fi-say, you have a MacBook Air or a tablet or some other device that doesn’t have an ethernet port-do what you can to minimize interference. MicrosoftĬlick the Network column in Windows Task Manager to see which apps, if any, are sending/receiving data on your network.

Again, we’re trying to learn how much bandwidth is coming directly into your home, before it begins getting divvied up among connected devices. If you have any other wired devices on your home network, plug your test computer directly into the modem so those don’t interfere. Let’s turn to the PC. For best results, you’ll want to use a wired connection if at all possible that way, you don’t have to worry about interference and performance fluctuations that can occur while you’re on Wi-Fi.
