What causes some devices to do worse on WiFi
Even in optimal conditions you can see that a device works much worse for you on WiFi than another that you have next to it. This can happen for different reasons. Sometimes you can try to solve them, while on other occasions, most of them will depend solely on the characteristics of that device.
Limited network card
The first reason is because of having a limited network card. For example a computer, you can have one with a wifi card that supports more speed than other. In this way, although the two are in the same location and apparently everything is the same, you can notice notable differences between one and the other.
You will notice this especially in devices with less power, such as an electronic book. Even if you have access to the WiFi network, it will surely have much lower speed than other devices such as a computer or a mobile phone, which do have a more powerful network card.
worst antenna
Something similar happens with the antenna, although this time we are going to notice it in the coverage. You are still in a room where you receive the signal very well on a computer, but instead you connect with a tablet and you see that less coverage arrives or you cannot even connect.
If you have the problem in a computer, you can always buy an external network card that has a better antenna. You can connect it to a USB port and thus achieve a greater range to be able to connect no matter how far away you are from the access point.
double band or not
Another factor that can affect WiFi devices is whether or not they are dual band. It can be decisive to achieve maximum speed. There is the possibility of using devices that work both in the band of 2.4GHz as of the 5GHz. Each of these options has its advantages and disadvantages. Basically the first allows us to connect from further away, but with less speed; the other allows maximum speed, but with less distance.
If you have speed problems on one device, while it is much better on another, it is probably because it does not have dual band and you cannot connect to the 5 GHz band. You will only be able to navigate through the 2.4 band GHz
Device conditions
Of course, the conditions in which that device is found will also influence. For example, if you have a device connected by WiFi in an area where there may be interference, that will affect signal. This happens if you are surrounded by other devices, such as a television.
In this case you have to analyze that the conditions are optimal to have the best quality of the WiFi network. This way you will ensure that the devices connect correctly to the wireless network and the annoying cuts and navigation problems do not appear.
In short, these are some of the main reasons why some devices work worse on WiFi, while others in the same situation do much better. In some cases you will be able to improve it and make the connection better, but other times it will depend on each device and its characteristics.
