Current routers work in various frequency bands in the same WiFi network. That is, you have a single SSID or WiFi network to which you connect but the device automatically decides which band to connect to depending on what it considers to be best. This has advantages and the main one is that we can connect to the same network and it will assign us the best frequency band. Something especially useful if we do not know the differences or advantages of each one. But it also has drawbacks and may be slowing down your browsing.
If you deactivate the function you can have many advantages and we will explain why.
What advantages does it have
As we say, connecting to the band assigned to us by this “smart” function of the router has many advantages. It is a technology that we find in devices of many brands and in devices that operators install when you contract fiber, without having to buy a separate router.
Among the advantages it offers us is that it allows us to connect to the 2.4 GHz band if we are far away or it will automatically connect us to the 5 GHz band if we are close. The difference between the two is that the first offers us more width or distance but less speed. The second, the opposite: it gives us better speed although it doesn't go as far. And the device will be in charge of choosing one or the other depending on where we are and what suits us best.
There are also other advantages such as the possibility of choosing which one we connect to depending on the clients that have already connected to one band or another. If there are many devices connected in the 2.4 GHz band, it will automatically send the new client to another band in order to balance and not saturate, for example.
