What causes laptop WiFi to go bad
If you browse through internet from laptop, you download a file or you simply do a speed test and you see that little arrives, but instead on another device it works fine, it can happen for different reasons. Some of them you can solve in a simple way, while others are going to be limitations of the computer itself.
hardware limitations
The first cause is that you have hardware limitations, more specifically in the wifi card. Your laptop may be old or the internal card it has is limited and does not allow you to navigate at a high speed or have good coverage. This is something that can happen in many devices and that especially affects laptops.
To solve this problem you can choose to purchase a new network card. You can buy an external one, which has greater coverage and thus be able to have better speed and avoid annoying cuts that affect the performance of the equipment. It is important to know what the maximum speed of the network card is.
do you have any malware
Another reason why WiFi is slow on the laptop and may be fine on other devices is that there is some kind of malware. maybe you have some virus that you have downloaded through some program or file without realizing it. That may be slowing down the connection.
To solve this problem it is essential to have a good antivirus. This will help you detect problems and correct them as soon as possible. For example, Windows Defender is a good solution, but there are many others, both free and paid. Whichever you choose, you should check that it works well.
Equipment is outdated
Do you have the equipment updated correctly? If it is not, it may be weighing down the quality of the WiFi connection. For this reason, it is always advisable to verify that you have the latest version of the operating system. This will help not only to improve performance, but also to correct possible problems that appear.
Something more concrete is to check that the network card is up to date. To do this you have to go to Start, enter Device Manager, Network adapters and there you select the one that interests you, which in this case is the WiFi card. Click on it with the second mouse button and click on update driver.
You don’t use the right band
Current equipment can work in both the 2.4 and 5 GHz bands. Using one or the other can mean a significant change in signal quality. Therefore, we always recommend choosing well. Basically we can say that the first is the one that allows you to navigate from a greater distance from the router, although with less speed. Instead, the 5 GHz is the one that offers the highest speed, but is more sensitive to distance.
If you see that he laptop Wi-Fi does not work well and other devices connect faster, you can check if you are using the correct band and choose another one to verify that it works correctly.
you are in a dead zone
One more reason is that you are in an area where little coverage arrives, while another device is better placed. This is commonly known as a dead zone and is basically a place where the WiFi signal is very limited or not at all and you cannot connect.
In this case, what you would have to do is change the location or use some device to improve the signal. For example a WiFi repeater, Mesh system or PLC devices that help improve coverage.
