Can't access AP Mode in EYESY

I purchased a second hand EYESY and I can’t access AP Mode doing the steps indicated in the manual. I re-flashed the SD card using BalenaEther with the latest firmware to make sure it was factory reset but still doesn’t work. I’m sure the USB Wifi adapter is connected, press shift and turn it on and it just starts normally. Can’t find the EYESY network on my computer or my phone… Am I missing something?

Bad wifi adapter?

That’s what I’m afraid of… do you know if C&G sell just the adapter?
