You can also use a smartphone to scan nearby wireless networks and see which channels others are using, then switch your router to a less crowded option. “The first step,” says Richard Fisco, who oversees electronics testing at Consumer Reports, “is to make sure your router is set to automatic channel selection and reboot it.” This, he says, will enable the router to look for a free channel to connect to. But given the limited number of channels, people in high-population areas may find that some get more crowded than others-which can mean the difference between a smooth Zoom call and one that’s a pixelated mess. If your router is on a low-traffic channel, there’s little to slow it down. But during rush hour, you’re at the mercy of the cars in front of you.
If you get lucky and the road ahead is clear, you can go as fast as you want-minding the speed limit, of course. Think of it this way: Interstate 95 is a major highway, but it only has so many lanes. This tip applies more to apartment dwellers in big cities than people who live in single-family homes in the suburbs.Ī channel is essentially a slice of the WiFi spectrum used by your router.
