I have very limited Pi experience.
I had a fully working Pi3B, I updated it, now no wireless or Bluetooth.
After 24 hours of failed investigation on the Pi3B I cut my losses in time and bought a Pi3B+ along with Pimoroni 16GB sdcard supposedly containing a “noobs image” but I think it’s a raspian image only.
I read and saved that image and then wrote the image onto two other sdcards.
I put the one copied sdcard in the Pi3B+ withOUT wired network it booted directly into raspian desktop at the welcome screen waiting for setup, no usual NOOB choices offered. Immediately the Bluetooth icon is BLUE not grey leading to being able to insert wifi setting and completing update
I put the other copied sdcard in the suspect Pi3B withOUT wired network it booted updated directly into raspian desktop at the welcome screen waiting for setup, no usual NOOB choices offered. Immediately the Bluetooth icon is GREY (not blue) so I will not be offered the chance to put wifi credentials.
This to me confirmed that the wifi is not working on the Pi3B and will not work.
Is there some way that updating the Pi3B a week ago could have destroyed wifi, is this a FATAL error? My 24 hours of investigation making command line wifi settings etc already failed.
Could I pretend it doesn’t have wifi components and buy the Pi wifi dongle and make it useful again or am I throwing good money after bad?
