What channel are you tuning your monitor interface to? Also can you elaborate on how you are testing transmitting over an injected monitor interface exactly? For example I just tested with two wireless cards, an ath9k and an iwlagn in two separate frequencies, 2412 and 5320 provided iw list lists on both interfaces: * 2412 MHz [1] (14.0 dBm) * 5320 MHz [64] (15.0 dBm) (passive scanning, no IBSS, radar detection) I use this script to create the monitor interfaces: --- #!/bin/bash FREQ="2412" #FREQ="5320" # Create the monitor interfaces sudo iw phy phy0 interface add mon-ath9k type monitor sudo iw phy phy1 interface add mon-iwlagn type monitor # Bring the interfaces up sudo ip link set mon-ath9k up sudo ip link set mon-iwlagn up # Tunes to desired freq sudo iw dev mon-ath9k set freq $FREQ sudo iw dev mon-iwlagn set freq $FREQ --- Then on two separate screens I compiled and ran packetspammer [1] from Andy Green. Which BTW andy can you post the link the actual git tree? I had to download each blob to download this, and couldn't find the git URL heh, will like to update the URL on Documentation/networking/mac80211-injection.txt.
