We use it every day, but we don’t yet know all its secrets. Did you know, for example, that your SFR box had two different frequency bands for wifi, 2.4 GHz and 5 GHz? We explain what the two are for, and how to switch from one to the other.
If there is one technology that has revolutionized our use of the Internet, it is wifi. Thanks to it, the connection has become mobile, and can be done at any time on multiple devices: computers, smartphones, tablets, consoles, and even connected objects (speakers, bulbs, etc.). So many uses that lead to diverse and varied uses. And this is precisely why some SFR boxes offer two different frequency bands:
The 5 GHz bandmore powerful than 2.4 GHz, and recommended for computers and smartphones.
The 2.4 GHz bandless powerful than 5 GHz, but with better coverage, recommended for connected objects.
What are the differences between 5 GHz and 2.4 GHz networks?
Technically, a quick mental calculation makes it possible to understand that the wifi signal using the 5 GHz frequency band is a little more than twice that of the 2.4 GHz band. But while that means the network offers a more stable connection, with higher throughput, it will also have less coverage than 2.4 GHz. To popularize, in a small dwelling, apartment type, in which the wifi is mainly used for computers and smartphones (for teleworking, gaming, etc.), it is absolutely necessary to favor the 5 GHz frequency.
On the other hand, in a large house with a lot of connected devices (cameras, speakers, bulbs, etc.), it is better to ensure the best possible coverage, and opt for the 2.4 GHz frequency. A remark that is all the more relevant since within a building, the 2.4 GHz network can be the victim of interference with other devices using this frequency.
Wifi: how to switch from 2.4 GHz to 5 GHz?
To check if your wifi is indeed on the 5 GHz frequency, you just have to consult the name of your connection, by going to your wifi settings. If the acronym 5 GHz appears at the end, it is that it is already the case.
Note also that on the SFR Box 8, with Smart WiFi, the management of the two bands is automatic, and is done according to the needs of your equipment.
How to check if your box is compatible with 5 GHz wifi?
If your wifi connection does not have “5 GHz” in its name, it may be because your box model does not offer both frequency bands. This option is only found on the SFR Box 8 (and the new SFR Box 8X), as well as on the Box Plus, which looks like this:
If you do not have this model, it is therefore normal that you cannot switch from the 2.4 GHz band to the 5 GHz band. Another more than notable clue, on the back of your modem, you can find the names of the two networks:
If only one wifi network name appears, it means that you cannot switch from one to the other, your box therefore only offers one. On the other hand, if you have both, this is the same wifi security key that you can use.
To change model and be able to benefit from the 2.4 GHz and 5 GHz networks, simply modify your offer in your personal space on the SFR online store.
