How to check internet speed, WiFi Viettel, FPT, VNPT on the computer

Sometimes when you use WiFi, you will feel the network speed is reduced or greatly slowed down. In this article, I will guide you some ways to check the Internet speed, WiFi Viettel, FPT, VNPT on a computer simply and quickly.

1. How to check WiFi speed?

WiFi speed test help you know how fast the WiFi network is using? High or low? Is the speed steady or flicker? From there to get solutions to overcome this situation.

- The process of testing the network speed

Testing network speed is measuring three factors: ping speed, download speed, upload speed. Measured results from these three factors will reflect how fast or slow the WiFi network is.

+ Speed ping (ping rate) : This parameter represents network latency. The ping rate is the amount of time a packet is sent from one computer to another and then receives the response signal back. The lower the ping speed, the stronger the speed of your WiFi network, in Vietnam, the best rated ping speed is usually below 50ms (Milliseconds) .

High ping makes using the network more difficult

+ Download speed : Download speed is the speed of downloading data from the Internet to your computer via the Internet, is calculated by MBPS (megabits per second) .

+ Upload speed: The upload speed is also known as the speed of downloading data from your computer to the network. Currently, WiFi networks use fiber optic cables, so the upload speed is usually equal to or not too much difference compared to the download speed.

Download speed and upload speed

- Benefits of testing network speed

Regularly check the network speed to help you know how fast or slow the network is, especially for WiFi networks that have been in use for a long time. This will help you quickly overcome if the network speed is low so that you will not be interrupted by work and daily activities.

2. Test the network speed by web

Note : Before taking the network speed measurement, you need to make sure that there are no programs on your computer that are downloading, uploading or updating, and that no computer is using the same Internet. This will help the most accurate measurement results.

- Use SpeedTest

+ Step 1: Access the SpeedTest website

Go to SpeedTest website > Press the Go button to get started.

The Go button

+ Step 2: Compare the results

You wait range 5-10 seconds for the measurement system and the results of the three parameters: speed ping, download speed and upload speed .

Results returned

In the download speed and upload speed section, since the web unit is Mbps , you need to convert it to MBps by dividing by 8 .

For example , the Download speed in the picture is 85.81 Mbps, divided by 8 is 10.72 MBps. That means when you download data, 10.72 MB will be loaded per second.

- Use Fast

You visit the Fast website . Upon entering the homepage of Fast, the system will automatically measure your Internet speed and give immediate results.

Results measured by Fast

You can press the Reset button to measure again.

3. How to check the WiFi signal strength using Command Prompt

- Step 1: Open the Command Promt window

Click the Search button > Enter "Command Promt" in the search bar> Select Run as administrator .

Open the Command Promt window

The Command Promt window appears with the interface as shown below.

Command Promt Window Interface

- Step 2: Check the WiFi signal strength

Copy the command below and paste it into the Command Prompt window.

netsh wlan show interfaces

Enter the command into the Command Prompt

The result is a series of information related to the WiFi connections on the computer. You look at the Signal line, you will see the results of WiFi signal strength measurement (As shown in the picture is 56% ).

Observe the Signal line

Normally, the signal strength of WiFi is considered to be 75% or better . If it is below 75%, you should move the WiFi Router to near the computer or check if the Router is damaged and replace it with a new one.

4. How to check the WiFi signal strength using PowerShell

- Step 1: Open PowerShell

Right-click the Start button in the left corner of the screen or press Windows + X > Click Window PowerShell (Admin) .

Open PowerShell

The PowerShell window appears with the interface as shown below.

PowerShell window

- Step 2: Check the WiFi signal strength

Copy the command below and paste it into the PowerShell window.

(netsh wlan show interfaces) -Match '^ \ s + Signal' -Replace '^ \ s + Signal \ s +: \ s +', ''

Enter the command into PowerShell

The result is the percentage below the command line you just copied to the window. This number ( 99% ) represents the strength of the WiFi signal that your computer is receiving.

Results WiFi signal strength on your device

Normally, the signal strength of WiFi is considered to be 75% or better . If it is below 75%, you should move the WiFi Router to near the computer or check if the Router is damaged and replace it with a new one.

5. What to do after testing the network speed?

After you have checked the network speed and found it slower than the service package that the carrier has committed in the contract, please contact the operator's switchboard to resolve.

Also, a slow network speed can be due to a number of reasons. You can consult and find ways to fix:

- Too many people use the same network : Many people accessing the same WiFi network will slow down the network speed. You should regularly change the WiFi password to avoid neighbors and people spending your home WiFi "temple".

Many people use the same WiFi, causing the network speed to decrease

- Old WiFi Router : If you have installed WiFi for a long time and have not renewed the Router , this is also a cause of slow network speed. You should clean, warranty or replace the WiFi Router to overcome this situation.

Need to replace another WiFi Router after a long time of use

- The cable is old or exposed : The cables connected from the street to the WiFi Router or the power cord of the Router may be old or exposed due to the bite of a mouse, cat, ... causing the transmission speed to decrease. . You can contact the operator's operator for advice and support.
