                Do your Raspberry Pi's Network Interfaces freeze? This may solve it.
              
          
    Do your Raspberry Pi's Network Interfaces freeze?

My Raspberry Pi 4 kept losing its wlan0 interface. I could usually reconnect via Ethernet but, from time to time, I noticed that the eth0 interface would also go walkabout.
I tried a lot of things but the one described here seems to have cured the problem. I have no idea why it works. It just does.
Step 0 - are you a Windows user?

The script shown in the next step should be created on your Raspberry Pi. Please do not make the mistake of selecting the text, copying it into a text editor on your Windows machine, saving the file, and then moving the file to your Raspberry Pi. Unless you take precautions, Windows will add its 0x0d 0x0a (CR+LF) line endings and those will stop the script from working properly on your Raspberry Pi.
