2.4 GHz or 5 GHz: which Wi-Fi band for your TV?

Most routers send two Wi-Fi bands. They behave differently, and choosing the right one can fix buffering.

The difference

• 5 GHz: faster and less crowded, but the signal weakens quickly through walls and over distance.
• 2.4 GHz: slower and shared with microwaves and neighbours' networks, but it reaches farther.

When to use 5 GHz

If the TV is in the same room as the router, or one wall away, 5 GHz is usually better. It gives higher and steadier speed for HD and 4K.

When to use 2.4 GHz

If the TV is far from the router, or behind several walls or on another floor, 5 GHz may be too weak. 2.4 GHz can be steadier there, though slower. A cable or a mesh unit near the TV is better still.

How to check which band the TV uses

1. Open the TV network settings.
2. Look at the name of the connected network. Many routers add 5G to the 5 GHz name.
3. If both bands share one name, you can usually pick the band in the router settings.

How to test

Run a speed test beside the TV on each band and keep the one that is faster and does not drop. Aim for a steady 30 Mbps or more.
