I have my raspberry hooked up via ethernet to a printer.
So what happens is the raspberry takes about 4 mins to get itself ready as a sort of server, and by that time the printer gives up trying to connect. I've set the PI to be a DHCP server so the printer gets that early (within 30 seconds of getting power).
So after 4 mins is there a way I can disconnect the ethernet port and have it reconnect, so to the printer attempts to connect itself once it notices the ethernet cable was plugged in.
At the moment after 4 minutes, I manually remove the ethernet cable and plug it back in and alls ok. Is there a way I can do this via commands, to temporarily switch off the ethernet and reconnect it?
