WiFi connectivity is widely used by all of us to connect to the Internet, and also to the different shared resources that we have in the local home network, such as a NAS server or directly our Windows computer that shares files in the local network . Although it is the preferred form of connection for all of us, it is not always the ideal way to connect to the Internet. Today in this article we are going to show you 5 cases in which it is not advisable to connect to a WiFi network, and it is better that you use another connection method such as the Ethernet network cable, PLC, etc.
Do not use WiFi in these cases
The latest wireless standards like Wi-Fi 6 and Wi-Fi 6E bring with them many important improvements, such as lower latency, higher capacity, and also higher actual speed. However, there are certain uses where it is better to leave the WiFi connection in the background.
Transfer of many GB in the network
Nowadays we transfer many GB of data in the local network, to store it in a NAS server or to save it in the Internet cloud. If you use WiFi to transfer tens of GB, what we will achieve is that other devices have a much slower speed, because the channel is “busy” with our data transfer, and the rest of the connected wireless devices will be affected by this use.
The best thing if you are going to transfer tens of GB in the local network or upload it to the Internet, is to use the Ethernet network cable or some PLC devices if you can, with the aim of “freeing” the WiFi wireless network to the rest of the devices, such as computers. laptops, smartphones and even the Smart TV if you have connected it via WiFi.
Continued use of the network
If we connect our Smart TV via WiFi to play Netflix, Amazon Prime or Disney+ content, we will be transferring data continuously. This causes the channel to be continuously busy, and if we have other wireless devices connected, we could notice a higher latency in the connection and also certain “lags”, because the Smart TV is continuously transferring up to 20Mbps when playing 4K content.
We are always going to recommend connecting the TV via cable, because not only will it work better for you, but it will also leave WiFi connectivity for devices that cannot use the cable connection.
Online games are very sensitive to latency and also to jitter in the connection , we always have to have the minimum possible latency in our Internet connection, and this also includes the way to connect to the router, because if we connect by WiFi we will add some milliseconds to the final connection, which could lead to a poor user experience.
Jitter is the variation of latency, if we have other devices connected at the same time by WiFi such as a smart TV or a computer, we will notice that we have “lags” in online games, either on a console or on our PC, because the other devices are taking up “air time,” which is what this is called when we’re talking about wireless networks. The best thing you can do is connect by cable to have the minimum possible latency, and a jitter of 0ms.
You need maximum stability without cuts
In the event that you need the connection to be as stable as possible and without any type of micro-cut, to make video calls or VoIP calls, then WiFi connectivity will surely not meet your needs, since the use of the same network by from other devices could cause high latency and even small drops in the connection if the firmware of the router is not well programmed.
In these cases, if you are going to make the video call with a mobile, you have no choice but to use the WiFI network, but if you are using the laptop or PC for a work meeting, in these cases you can connect by cable directly to the router or to the net.
If your communications need maximum security, and you are not sure that your WiFi network is secure, then what you should do is disable the wireless network from the router, and connect directly to the router by cable. In this simple way, you ensure that all your communications are secure and free from malicious users.
As you can see, there are certain cases in which it is not recommended to use WiFi networks, either for speed, stability or security.
