If your Wi-Fi connection remains interminably slow no matter how many times you restart it, you can probably blame your neighbor. It could be that there are too many people using Wi-Fi connections on the same channel, even if you're all on different networks. But, as Tech Insider teaches us in the video below, there is a way to circumvent this, returning you to the prime TV-streaming Wi-Fi speeds of your dreams. (These instructions apply to Mac users, but if you've got Windows, How-To Geek recommends a tool called the Xirrus Wi-Fi Inspector to do the same job.) It seems like a lot of steps at first, but it'll be worth it—we promise.
If you’ve got a Mac, hold the Option key while clicking the Wi-Fi symbol in your top menu bar. Go to “Open Wireless Diagnostics,” then when that opens, go up to the top left menu bar and click the drop-down menu “Window > Scan.” That will open up a window with all the nearby Wi-Fi networks. Click the “Scan Now” button on the bottom right, and your computer should recommend the best channels for you to use—say, you’re on Channel No. 1, but the best 2.4GHz channel is No. 3. Tech Insider recommends writing those down (there are options for both 2.4GHz channels and 5GHz channels).
Now, you’ll need to break out your iPhone. Download the AirPort Utility app, and go to your phone’s settings. Scroll down to the AirPort Utility app in your app list, and enable “WiFi Scanner.” Use the app to scan your house for Wi-Fi networks and note which channels are commonly used by your neighbors’ networks. (If you don’t have an iPhone, you can also use Acrylic Wi-Fi for Android or Windows phones.) This will help you avoid the most congested networks.
Then, log onto your router on your computer by typing your router’s IP address into your browser, just like you would any web address. From there, go into Wireless Settings, and change the channel your network operates on to one of the recommended options that you wrote down from your computer's diagnostics window earlier. And don’t forget to save!
This should help you get a faster internet connection by minimizing the amount of interference from other networks around you. Because the best neighbors are the ones who don't slow down Game of Thrones for you.
