A lab instruction for city assessors mentions rfkill blocking. What should they understand?
Select an answer to reveal the explanation.
Short Explanation
rfkill is the city’s big red “radio silence” switch—software or hardware can flip it. Drivers can be fine while the radio still stays dark. Check soft and hard blocks before assuming the dongle is dead.
Full Explanation
The rfkill subsystem can soft-block or hard-block wireless radios independently of whether kernel drivers are installed. A blocked interface will not transmit or receive as expected until the block is cleared. Troubleshooting monitor-mode failures should include rfkill status checks.
