Popular Science has some advice for speeding up your Wifi.
1. Download firmware from your router manufacturer’s website. Software updates fix bugs and may also include performance upgrades, as well as extra support for newer devices on the market.
2. Most routers use channel 6 by default. Change this to 1 or 11 (to minimize interference with channel 6), and you might notice an uptick in Wi-Fi performance. All of your connected devices will also have to adjust their channels, but the majority of your gear will do this automatically, with no need to adjust the Wi-Fi name or password.
