If you're having issues with your Wi-Fi speed all of a sudden, you may be able to blame it on a little-known problem with an easy solution: your router could be competing with your neighbor's router.
Many don't know it, but Wi-Fi is divided into different channels. Even if your neighbor has a different internet service provider, you could be on the same channel. Switching the channel on which your router is broadcasting could boost your speed.
Most routers automatically look for an open channel, but you can also do it manually using the Airport Utility on Apple products or the WiFi Analyzer app for Windows and Android. You can find out how to do it step-by-step here.
You can run a speed test on your own computer using speedtest.net. Many internet and cellular providers, including Spectrum, AT&T and Verizon, also offer speed tests online. You can check with your service provider.
