EXPLANATION

Few devices are as essential to the smooth running of a modern-day digital household than a wireless router, so it’s strange that this black box is so little understood. Here we’ll outline one of the key features of many modern routers, dual band 2.4GHz and 5GHz support, so you know exactly what it is and how to take advantage of each.

Not every router out there offers both 2.4GHz and 5GHz, but most devices released in the last few years do. These boxes are typically advertised as “dual band” and while the specifics of each router are different, the principles behind these two bands are the same no matter what hardware you’ve got installed.
As well as a router that supports both these bands, you need devices that do too—and the vast majority of recent gadgets out there now do. Low-powered and older bits of hardware might be limited to 2.4GHz only, but they’re becoming less common.
