The fact of connecting a good number of devices to the WiFi of our home or office is not always the most recommended. More than anything, because if you have started to go wrong after doing just this, you already have the answer here. Basically, because what the experts recommend the most is that we do not count many devices to the same wireless connection.
However, if in your case you want to do it because you need it for any reason, the truth is that it is better that you follow a series of tips so that the wireless network in your home does not start to go wrong at all times. Therefore, you should quickly take a look at the following recommendations.

Use both bands
One of the main inconveniences and mistakes that we usually make is that we only use a bandwidth that the router offers us, either the 2.4 GHz band or the 5 GHz band. In any case, so that we do not have so many congestion and interference problems, your thing will be to use both to connect different devices. So not all devices will go on the same broadband.
In addition, the ideal will be not to have excessive bandwidth consumption . For example, do not start downloading large files from a device if the network works poorly or you have disconnections in the rest of the devices that are connected to WiFi. If you connect two or three, you will hardly notice the difference, but the moment you establish connection in more devices, it will be the moment in which the bandwidth will decrease.

Upgrade to a better router
Another drawback that not everyone takes into account is the quality of the router . For this reason, it is important to have a good router at home if we want to be able to connect different devices to WiFi without having many problems or with the connection.
Also, if you have problems, the safest thing is that the device you have is limited and, therefore, it will not let you connect so many devices at the same time without giving you one error or another. Therefore, make sure you first have a router that does not have any type of limitation.
Use a quality repeater
Finally, although it is a good idea to use a repeater, not all of them will work for us. To connect several devices at the same time to the WiFi network, it will be better to use a repeater that is powerful . It may be that the wireless connection of your router is not strong and to take the network to other places you use a Wi-Fi repeater or Mesh system. But, the problem will also appear if you do not have a powerful enough repeater to connect all the devices, since the connection will not be the same for all.
That is why it is better that you start using a repeater that is dual band, in addition to the fact that the ideal is that it has a good speed and characteristics that allow you to connect many devices to the WiFi without cuts appearing or the connection starting to go slower. In this way, you can ensure that there are no problems with the wireless connection in your home.
