You can try using nmcli. It shows a signal strength of sorts (percentage?).

nmcli device wifi

You can monitor it with

watch nmcli device wifi

Thank you.

Is there any way to know the signal level information of the currently connected WIFI?

Do you mean the strength of the network you’re currently connected to? There should be an asterisk (*) next to the SSID that you’re connected to.

For other options, check out this post. I think wavemon might be close to what you want.
