Overview

This guide explains how to fix weak, laggy, intermittent Wi-Fi on laptop in clear, practical terms. It covers the key concepts, recommended steps, common limitations, and useful checks so you can make a better-informed decision.

The horror of using the internet is the laggy, unstable network. This is even more terrible when you play games. That is why the weak Wi-Fi laptop error makes many users feel uncomfortable. This weak Wi-Fi error is a fairly common error, occurring mostly with all laptop users. So how to solve this situation? Let's explore how to deal with the weak Wi-Fi laptop error in This guide!

1. Restart Wi-Fi

The device that is responsible for broadcasting Wi-Fi for other devices to use is the Modem/Router. With the intensity of maintaining 24/7 operation, the Wi-Fi transmitter will always encounter a state of heat and overheating. This causes the internal components of the Modem/Router to operate with poorer quality, leading to poor Wi-Fi signal and unstable connection. Therefore, if your laptop has weak Wi-Fi, restart the Wi-Fi or at least let it rest for about 1-2 minutes and then restart. Although this method is straightforward, many people have successfully applied it!

2. Unlock bandwidth on laptop

Normally, to ensure stability, the laptop Wi-Fi card will be limited to a certain level. However, if your laptop's Wi-Fi connection is weak and does not ensure stable quality, we can adjust the Wi-Fi access speed on the laptop in the following way:

Step 1: Access Device Manager by right-clicking on the Window icon in the left corner > select Device Manager (or search in the Cortana Search box)

Step 2: In the Device Manager window, select the following steps: Ports/ Communications Ports/ Port Settings tab, set the Bits per second option to the maximum (ie 128000) and the Flow control item to Hardware then click OK to save.

3. Scan for viruses and remove malware

While using the Internet, we accidentally access unhealthy websites or files shared on the network, leading to the computer being infected with viruses or installing malicious software without knowing it. The laptop's weak Wi-Fi connection or even no Wi-Fi connection can also be due to this reason. Therefore, if your laptop suddenly encounters a weak, unstable or disconnected Wi-Fi connection, check your daily usage habits, scan for viruses and remove the software you suspect.

4. Move the Wi-Fi transmitter to a more suitable location

For general users, most people use routers provided by their network operators or cheap mid-range Wi-Fi transmitters. The downside of these transmitters is poor coverage, affected by space or obstacles. If you encounter a situation where your laptop has a weak Wi-Fi signal, make sure the place of use is close to the transmitter or place the Wi-Fi transmitter in a central location where it can achieve the best signal transmission without being obstructed by walls or other objects.

5. Update Wi-Fi driver on laptop

Driver is the device manager on the computer. If it is faulty or damaged, it will also affect your Wi-Fi reception ability. Updating the Wi-Fi card driver is also quite easy. The steps are as follows:

Step 1: Access Device Manager

Step 2: Select Network adapter > Uninstall Wi-Fi card driver

Step 3: Reset the computer. After resetting, for Windows 10, the missing drivers will be automatically updated.

6. Clear cache, web browsing history

Cache is a temporary data used by different browsers such as Internet Explorer or Google Chrome, Mozilla Firefox, etc. It helps users to open web pages quickly without having to reload the content. This cache is designed to increase internet speed but sometimes it can slow down if it exceeds the size limit. In this case, you need to clear the cache to improve the poor Wi-Fi connection.

If you are using Chrome browser, you can do the following:

Step 1: On Chrome browser, press Ctrl + H

Step 2: Select Clear Browsing data

Step 3: In the Time Range section > select All time to delete all web history > click Clear data to perform

7. Call the operator

After performing all the above operations but still cannot fix the laptop's weak Wi-Fi connection error, we can only use the last method of calling the operator. The operator's operator can help you diagnose the status of your network on the system and provide appropriate solutions.

In case it cannot be handled immediately, technicians will be sent to support you. You can refer to the hotlines of the network operators below:
