4 Things About 2.4 GHz vs 5 GHz Wi-Fi

4 things about Wi-Fi bands that explain your weak signal

Lesson notes

Key points

2.4 GHz reaches further: Lower frequencies pass through walls better, so 2.4 GHz covers more distance.
5 GHz is faster: 5 GHz offers wider channels, giving higher data rates at shorter range.
Only 3 clean channels: On 2.4 GHz, channels 1, 6 and 11 are the usual non-overlapping choices.
5 GHz is less crowded: More non-overlapping channels on 5 GHz means less interference from neighbours.

Takeaway: 2.4 GHz trades speed for range; 5 GHz trades range for speed.

Quick check: Which 2.4 GHz channels are commonly used because they don't overlap?

1, 6 and 11
2, 4 and 8
3, 7 and 12

Channels 1, 6 and 11 are spaced far enough apart to avoid overlap.
