When Wi-Fi connection is slow, two ways to check the radio wave intensity

I think everyone has seen this abominable network bar.A small icon showing the Wi-Fi connection status.

The fact that all bars are on is that the Wi-Fi speed is sufficient, but if not all are on, the WiFi connection environment is bad.

"Is it hopeless if only one of the three is on?"

"Why can you see Netflix even if only one bar is on?"

"When the two bars are on, are they three or one?"

"Is it better to go near the router, or is it okay?"

The information indicated by the bar is full of mysteries and frustrated.

To determine whether the Wi-Fi connection is good or bad, let me know another method, rather than relying on such a small icon.

From now on, start a command prompt instead of seeing the icon and examine the wi-fi connection quality in more detail.(You can use PowerShell without worry)

Check the connection status at the command prompt

First, you have to start the command prompt.

Click the start button of Windows, search for "Command Prompt", and start the following command.

If you have a Wifi connection, you should have the following response.

In the "Signal" line, you can see the strength of the Wi-Fi signal, albeit any number.("Optional" is because the connection is interrupted before 0 %).

If you want to know the Wi-Fi connection DBM value, you may want to use a Third Party app, but if you are in trouble, you can use the above numbers.

If the value of "Signal" is 85-90 % or more, it can be said that there is a problem if it is 30 % or less if it is 50 %.

In other words, this figure is only a rough guide.

It is a good idea to walk around the house and go to a place where the wifi connection status is bad, or know what the WiFi connection signal is bad / normal / good.

Check the connection status with PowerShell

If you like to use PowerShell more than a command prompt, launch PowerShell and enter the following character strings.(From "Windows Central")

The numerical value of the signal is displayed as follows.

Only this!Enter other commands to get more detailed results.

Causes of slow Internet connection (other than signal strength)

The strength of the signal is useful data, but that is not the only cause when the Internet connection is delayed.

There are many other causes that affect download and upload status (and waiting time).

The problem does not solve the problem alone.

Other causes of the following are the following:

There are other possible causes.

However, if the signal strength of Wi-Fi is always low, we have reviewed the location of the router, the bandwidth used (2.4GHz and 5GHz), and whether the communication status to the connected device and access points is good.It may be better.

It is the beginning of trouble shooting journey.
