sudo aireplay-ng -9 wlan0 Monitor mode:
Some kernel versions (5.4+, 5.15+) break monitor mode. Fix: switch to rtl8xxxu with module param: tp tl-wn722n driver
Here’s a deep technical dive into the driver ecosystem—covering chipset realities, driver selection across OSes, monitor mode, injection support, and common pitfalls. 1. Chipset: The Real Identity The TL-WN722N comes in two major hardware revisions : sudo aireplay-ng -9 wlan0 Monitor mode: Some kernel
sudo ip link set wlan0 down sudo iw wlan0 set monitor control sudo ip link set wlan0 up For AR9271 v1, you should see: driver selection across OSes
Test 1 (injection on mon0): Works For v2/v3, often:
Injection rate: 0% or 100% but no packets captured AR9271: Firmware htc_9271.fw loads from /lib/firmware . Missing it → device fails with ath9k_htc: Firmware - htc_9271.fw not found .
