I also don’t have a bad wifi I tested it with other distros (including EmuElec) and it worked fine, in the end I had to save my roms, delete everything , and create it again from a clean image (in the process Batocera managed to corrupt one of my microsdcards while it was resizing the share partition), it took me a while but at least it works now (internal wifi is recognised). Not sure why upgrading (from 5.25 to 5.26) didn’t work, I even tried to copy the boot partition and system files from a clean 5.26 (that I knew had wifi working) but still the system was not finding the wifi, I also deleted the 1.0 firmware forcing the 1.1 firmware (removed the if case from the config) but still had the same issue (in this occasion I could use the L2 and R2 but not the wifi). The only solution was to create everything from scratch.
