Reasons not to share Wi-Fi with neighbors

Wireless networks are increasingly present in the daily lives of users. We have at our disposal a wide range of possibilities to connect. There are many Wi-Fi networks and devices to connect us. Precisely the improvement in wireless networks has also made more equipment appear that we can use to navigate the network without cables. We talk about tablets, mobiles, televisions and everything we know as the Internet of Things. However, we do not always make adequate use of the networks. In this article we will explain why we should not share Wi-Fi with neighbors. Some reasons that would make us think about it.

Why shouldn’t we share Wi-Fi with other people

Some users choose to share the wireless connection with other users, usually neighbors or relatives who live nearby. This logically saves costs. A single person pays for the Internet and multiple users can be used. In addition, technology has advanced in recent times and this means that there are less problems so that the coverage and speed are very limited.

This could be interesting and make many users take it into account. However, we must bear in mind that sharing the Wi-Fi connection with other users can bring problems that affect our connections and, ultimately, the way we navigate. It could also affect privacy and security, two factors that are so important when it comes to network connections and that we must take maximum care at all times. All this will make us put a scale to see if it compensates or not to have a shared connection with others.

Lower speed

One of the first issues is the loss of speed. Logically, when there are more users connected to the network, it means that they will consume more bandwidth. One home is not the same as two, for example. The connection we have is limited, it will have a specific capacity and especially we can have problems if the speed is not too high.

Therefore, the fact of sharing the Wi-Fi network with our neighbors to try to save will mean losing speed. This would also cause a lower quality and stability of the connection. Problems that, in short, affect the proper functioning when browsing.

We cannot control what other users do. Let’s take as an example that we want to make a video call. We are going to need low latency, good speed and stability. Otherwise there could be outages and we would have major problems. But of course, what happens if someone else is downloading files through Torrent and is taking the connection to the extreme? Logically there would be problems.

Security issues

Of course the security risks are going to be present. We already know that keeping the router running smoothly is essentially about security. We must avoid making mistakes that put our connection at risk, as well as using passwords that are strong and complex.

This means that if we are sharing the connection with other users, they could make mistakes that put the security of the network at risk. We do not only depend on how we take care of the connection, but we will depend on third parties and that all their equipment is correctly updated and there are no vulnerabilities that could put the rest of the network at risk.

Exceed the limit of connected devices

It is true that today modern routers are capable of connecting many computers at the same time. There is no limit at all as short as years ago and connections are not so influenced. However, it must be borne in mind that, although greater, there is still a limit. The more devices there are connected, the more performance problems we will have.

Therefore, the fact of sharing the connection with more users can mean that there are many more computers connected to the network. This would result in problems that can affect the proper functioning of the connections. And we already know that today we have more and more connected devices. We are talking mainly about what is known as the Internet of Things, which are all household devices such as televisions, smart bulbs or video players that are connected to the network.

Physical failures in connection

If we share the Internet with a neighbor, it means that the router may not be in our home. What happens if there is a physical failure that we have to restart the device at a given moment? Perhaps the other person is not at home and we cannot solve those problems in the short term. A known vulnerability may even have appeared and it is necessary to access the device quickly and carry out certain changes at a physical level.

Sometimes it is necessary to have physical access to a device to fix problems. To restart the router, you must also keep it off for at least half a minute before turning it on again. Only then will the changes be made correctly. Otherwise the problem would continue and we will not have solved anything.

Misuse of the connection

Do not leave behind a possible misuse of the connection. Maybe do illegal downloads, for example. We will be indirectly responsible for what other users do. We will be sharing the IP address and that can have consequences. It is something similar to if an intruder were to enter our network and use it in a criminal way. We must prevent this from happening.

In short, sharing the Internet connection with our neighbors can be something useful and interesting at certain times, but we must bear in mind that it can bring problems. We have pointed out those that are in our opinion the main ones. We must weigh the possible benefits that we have, but also the problems that this could generate. We can always opt for some solutions in case of need. For example, it could be to create a guest network if at any given moment we want to share the connection with our neighbors because they have run out of Internet or whatever. This could help avoid problems.
