Tell 2.4 from 5 gigahertz
What the numbers on a network mean, and which lane suits which room.
Gigahertz names the radio a network uses. 2.4 travels further and through walls; 5 is faster and gives up sooner.
Both come from the same router, and both reach the same internet.
Key points
- Gigahertz names the radio lane, not the speed you pay for
- 2.4 reaches further; 5 is faster over shorter distances
What to remember
- Leave both on and let each device pick.
- Near the router, take 5. Far from it, take 2.4.
Try this
Look down your own network list for a name ending in 5G. That is your router’s second lane.
