Ubuntu is installed on an SSD which is connected via USB. [Expected behavior] After switching off and on the wifi carrier I can still connect to my Raspi via ssh. [Observed behavior] After switching off and on the wifi carrier I can neither connect nor ping the Raspi. Neither on wlan0, nor on eth0. It looks like the device is stuck.
