I installed Ubuntu 24.04.1 LTS.
I have a RTL8723BE WiFi adapter.
After installation, I'm not able to find the WiFi adapter nor the WiFi symbol.
Also the WiFi adapter is not listed in the lspci output.
Surprisingly enough, Bluetooth works perfectly fine. However, if I try to disable Bluetooth, Airplane mode gets turned on and if I try to disable Airplane Mode, Bluetooth gets turned on. I remember reading somewhere that Bluetooth and wifi chip is same for RTL8723BE. Not exactly sure of the specifics. Maybe this can help ?
Edit - Adding the details as asked by @Jeremy31
