Wi-Fi has come a long way. Today’s routers—especially mesh systems—let you connect to multiple bands for faster, more reliable internet. But what do all those numbers mean?
Here’s your quick guide to 2.4 GHz, 5 GHz and 6 GHz Wi-Fi. We’ll explain what each one is good at, when to use them, and how to fix common Wi-Fi issues at home.
That blazing speed on your router’s box? It’s based on perfect lab conditions. No walls. No interference. No other devices.
Real homes aren’t like that.
Your speed can dip depending on:
Most people see about 40–70% of their router’s top speed—and that’s normal.
Most modern routers broadcast multiple bands to help balance speed and coverage. Here’s how each one works:
Best for: Smart switches, sensors, security cams, and devices that live far from your router.
Best for: Streaming, gaming and video calls on laptops, phones and TVs nearby.
Best for: Gaming PCs, VR headsets and 4K/8K streaming—when they’re close to the router.
Want to use 5 GHz or 6 GHz? Your device has to:
✔ Support that band
✔ Be close enough to the router
Most modern phones, laptops and smart TVs made after 2013 support 5 GHz. Devices made in 2021 or later (especially mid-range and premium ones) might support 6 GHz too.
Still unsure? Check the device manual or manufacturer website.
Here’s a quick guide:
Pro tip: If you see just one Wi-Fi name when connecting, your router probably uses band steering to pick the best band for you automatically.
