Is WiFi 2G or 5G better?

The primary differences between the 2.4 GHz and 5GHz wireless frequencies are range and bandwidth. 5GHz provides faster data rates at a shorter distance . 2.4GHz offers coverage for farther distances, but may perform at slower speeds. Range : how far your data can travel.

Since the 2.4 GHz signal is much stronger at that location, the 2.4 GHz connection just might also be faster than the 5 GHz connection.7 May 2015

If you want better range, use 2.4 GHz . If you need higher performance or speed, use the 5GHz band. The 5GHz band, which is the newer of the two, has the potential to cut through network clutter and interference to maximize network performance.
