I have successfully configured my RPI4s to network boot over an ethernet switch of a master RPI4 which acts as the ethernet DHCP server (using the tutorials).
Prior to netbooting, I had them working off of SD cards doing inter-cluster communications over the ethernet, and using WAN access via Wifi over wlan0 (e.g. to do updates etc).
The RPI4s that are netbooting over eth0 now report "No such device" for wlan0. Bluetooth also seems to be getting no such device errors (though I am not using it).
Is wlan0 not useable.after a net boot? Or, because the network fire up sequence is different, do I need to change my configuration? Note: WPA_Supplicant config was working before and I am using the same one now.
Ps. I am runing Raspiian Buster Lite from 2020-02-13.
