Why to check signal with PowerShell ?

When it comes to wireless internet and PowerShell, we are already used to looking at the bars on the phone display or monitor. One dash grid is weak, two dashes – things are better, three is just perfect, but what if we don’t have a graphical environment? If we can’t count the dashes? Then we have to use terminals and write commands! But do you think for a moment that you will never have to? You are wrong. Here is an example you have a home server, you have installed it without a graphical environment and because your wife constantly grumbles that there are cables everywhere, you decide to put it in a hidden place and with a wireless connection. Then you will need to find out how the network signal is using commands 🙂

So.. first things – first – open PowerShell console and type the following:

WAY 1

(netsh wlan show interfaces) -Match '^s+Signal' -Replace '^s+Signals+:s+',''
Code language: JavaScript (javascript)

You will se this simple output

WAY 2

Another way of checking is with the following command

netsh wlan show interfaces

You will have this simple output
