bluetooth, nfc, wifi, wwan
Enable, disable, toggle or check the state of builtin bluetooth, NFC, Wi-Fi and WWAN (3G/UMTS, 4G/LTE or 5G) radios:
bluetooth [ on | off | toggle ] nfc [ on | off | toggle ] wifi [ on | off | toggle ] wwan [ on | off | toggle ]
Using the command without arguments displays the actual state.
Hint: for Intel 2200bg and 2915abg cards call the command with sudo or in a root shell.
Prerequisite: the radio device must be supported by the kernel’s rfkill framework (except Intel 2100/2200/2915). This may be checked with rfkill list.
