Re: problem realtek 8723 driver
Arrrgh - 'rfkill' (a command I'm not familiar with) gave the clue - it showed the wireless LAN was hard blocked! 'Hard blocked' is again a term I'm not familiar with, but I correctly deduced that it's a hardware switch.

iwconfig still shows that wlan1 is used, instead of wlan0. I'm not sure I know why.
Many thanks, 'Chili555'!
