How to cut wlan0 on Raspi

Useful when Ssh is not responding well, or when you want to check the connection with soracom only.

I got the same error as below with cut 1 and it didn't work, but not even with 3.

Now it's done!

Just set up raspi-blackliset.conf

However, SSH is no longer available via USB.

ssh: Could not resolve hostname raspberrypi.local: nodename nor servname provided, or not known

I had no choice but to undo it and remove the wifi password to force it to not connect over wifi. I found a good way to do that below.

Ssh connection can be made via USB connection as follows

ssh pi@raspberrypi.local
