How to avoid the problems of having too many IoT devices over Wi-Fi

Having too many computers connected via Wi-Fi is a problem

although links Nowadays they have a larger capacity and allow to connect a large number of equipment, it should be borne in mind that the more devices we have, the more problems can arise. If we think of a home network, a router has a limited capacity to be able to offer a good connection.

We have to mention that we will not only have problems depending on the number of devices, but depending on the usage we give them. That is, it is not the same as being 15 . Internet of Things devices and other computers that are connected but where we only exchange information, using the browser or listening to music in streaming, rather than the fact that there are five computers and they are downloading large files and streaming video in the highest quality.

But apart from the possible issues with the Wi-Fi network with many IoT devices, we should also think about security. It is a fact that the more we have, the greater the risks can be. There are many security vulnerabilities that can appear and affect us.

Avoid security issues by connecting multiple IoT devices

Therefore, there is something vital to avoiding Wi-Fi and connection problems in general when using many IoT devices keep safe. We must keep in mind some of the tips that we are going to show to reduce the risks when connecting to the network and that there are no hackers who can steal data or harm its proper functioning.

Proteger la red Wi-Fi

An essential thing is to protect your Wi-Fi network. We will be connecting many devices to it so any failure or any security breach could be very harmful. It is necessary to obtain the maximum possible guarantees.

How can we protect the wireless network? The first thing is to have a file good password. This will be the main barrier so that intruders do not enter. This key must be completely random, contain letters (both uppercase and lowercase), numbers and also other symbols we put in, of type $% – & … so we can have a strong key.

but kind encryption that we will use. We should avoid the old and outdated ones, such as WEP. An intruder can use computer programs to find out the password, which is something we can avoid if we use more modern encryption such as WPA-3 or WPA-2.

Update all equipment

Undoubtedly, another aspect to consider is to have all Updated IoT devices. This will enable to rectify any security breaches that may arise which would open a gateway to cybercriminals who want to steal data or attack us.

We should apply this to any device we have connected to the network. Once we have a device, we must make sure that it has the latest version and that it will not have any exploitable gap.

Use strong passwords

Of course we should use Completely secure passwords on Internet of Things devices. This key will protect us, and prevent anyone from taking control. If we leave a computer unlocked, without any kind of protection, it will affect not only that particular machine, but also the entire network.

Additionally, in many cases they will allow you to configure two-step authentication. It’s basically a second check. The second step we must take is to enter a device or change the configuration. For example, it is usually a text text message with an icon.

Do not leave the values ​​that come from the factory

We must not leave Settings and defaults. An attacker can take advantage of this to gain access to the device. Sometimes they can even find some glitches that occur in a particular model and achieve their goal.

What we will do is change these values, beyond the password. For example, change the name that this computer will appear on the network. We will also check some aspects of security that we can modify, such as what we mentioned about two-step authentication.

Improved performance when connecting computers via Wi-Fi

But not only can we run into security issues by owning so many IoT devices, we can also suffer failures in that. Wi-Fi. In the end, our home router will have to solve a large number of requests. Even if we use a wireless repeater it may get saturated. It is appropriate to take into account some recommendations.

Use wireless repeaters

An important first tip is to use wireless repeaters, PLCs, or Wi-Fi to improve coverage. If we have many IoT devices connected, this means that we will distribute them throughout the house and in many cases they will be far from the router.

If we have this kind of device Improve your wireless connection, we can connect more devices without worrying about coverage. Thus we will always maintain good speed and quality.

Choose the right band

Modern devices usually have two bands to be able to connect to Wi-Fi: those of الخاصة 5 GHz and 2.4 GHz. The first is the one that offers the highest speed, but is more sensitive to distance and obstacles. On the other hand, 2.4GHz is better if we want to connect far from the router and it is more stable, although the speed is lower.

Therefore, we can also consider changing the scope if we see that there are problems. Even whenever possible, we can make use of 5 GHz, which is the device that will have the least interference with other devices. This will avoid the problems of having many IoT devices.

Differences between 2.4 and 5 GHz

Change the router channel

we have the Channel of the optimal router? If we connect many devices, choosing the right channel may be more important than ever. If we are connected to a saturated person, used by other neighbors, we may have problems.

We can always access the router configuration and change the channel when we have stability and coverage failures. This will allow us to connect more devices and no errors.

Use the cable when possible

Another factor that might be interesting is to do cable use when possible. Many IoT devices also allow them to be connected by wire, outside of a Wi-Fi network. This can bring more speed, but especially stability.

Therefore, if we have, for example, a TV with an Ethernet port and we have the opportunity to connect it by cable, we can avoid having more devices via Wi-Fi and thus generate fewer conflicts.

In short, these are some of the factors that we must take into account to avoid problems when using many IoT devices. On the other hand, we saw some tips to avoid security risks, but also some recommendations to improve the connection as much as possible and navigate faster.
