WLAN: 2.4 or 5 GHz - which frequency is advisable? All info

Current routers offer you two frequency bands: 2.4 and 5 GHz. For the normal user, this raises the question of which mode is recommended. We explain the advantages and disadvantages of the frequencies.

2.4 or 5 GHz? This is a question users often ask themselves, even in public WLAN networks.

Ideally, the WLAN runs quickly and without interference. The choice between 2.4 and 5 GHz can play a role in this.

WLAN: How to decide between 2.4 and 5 GHz

The differences between 2.4 and 5 GHz can be summarized as follows:

• Generally, 5 GHz WLAN is faster and more stable - and that makes it the better variant.
• However, this only applies if the general conditions fit. For example, 5 GHz has a lower range; the use therefore only makes sense if you have good reception everywhere.
• Furthermore, all receiving devices (smartphone, tablet, laptop) must also be compatible with 5 GHz.
• The use of 5 GHz consequently makes sense if all devices are capable of it and have good reception everywhere in the home. The latter can be optimized via repeater, by the way.

The switch between the frequency bands is done via the router user interface. For FritzBox! devices, you go to the "WLAN" area and then "Radio channel". However, this is often not even necessary, as many modern routers automatically select the best channel for the receiving device.
