My OSMC is no longer accessible via the WiFi network, no response to ping and impossible to connect via SSH.
I have power cycled several times but no go, still inaccessible.
If I ping from another RPi I get this response:
$ ping 192.168.117.139
PING 192.168.117.139 (192.168.117.139) 56(84) bytes of data.
From 192.168.117.131 icmp_seq=1 Destination Host Unreachable
But the device was connected to the WiFi network as witnessed by the network page in MyOSMC when I use the TV remote in Kodi to check the system. The IP address shown above as it should be according to DHCP reservation in the router.
If I reboot from the Kodi menu the restart takes a very long time and ends up with a disconnected device.
It seems like the OSMC device now has decided to totally disregard the WiFi network.
If I move the RPi from the TV into the office where there is wired network available then it is not doing this, but then I cannot use it on the TV of course…
I have looked into the /etc/wpa-supplicant dir but contrary to other RPi (non-OSMC) boxes there is no wpa-supplicant.conf file there, so how is the WiFi connection managed on OSMC?
What can I do to fix this?
