Extenders today can support single, dual or tri-band Wi-Fi, and they will tell you the maximum speeds they support on all of their available bands.

For the best performance, you’ll want to go with a Wi-Fi extender that has the highest speeds possible (and those, as you might expect, tend to cost more).
