For some unknown reasons, sometimes my WiFi connection gets very slow and the main cause is the ping time.

I should manually disconnect my WiFi and reconnect it.

I'm on Ubuntu 20.04 LTS.

I want to make it automatic. Here are the script snippets I came up with. But I can't put them together:

# Read time using awk

ping 192.168.1.1 | awk '{gsub("time=", ""); print $7}'



# Disconnecting from WiFi

nmcli con down WiFiName



# Reconnecting to WiFi

nmcli device wifi connect

I tried this, but it does not work:

while read Line; do

    echo "read line"

    echo $Line

done <<< $(ping 192.168.1.1)

Basically, I'm stuck at redirecting ping standard output to a while loop, and I'm stuck at aggregating the average time using the awk command.

How can I combine them together?

Update

For anyone interested in the final script, please see my answer below.
