After that, I gave up on WiFi on Raspberries and used LAN, but they are so underpowered… my nextcloud instance took ages to do anything, XBMC (now Kodi) was slow and couldn’t render videos > 720p (it was struggling with 720p honestly), even a simple audio proxy over bluetooth (forward bluetooth audio from phone to speaker) barely functioned as the bluetooth cut out or it was janky as hell.
It’s easier to put a old phone as a server than a raspberrypi.
