Hi all, I'm using: Ubuntu 9.10 Atheros card with ath9k compat-wireless latest stable version ad-hoc 802.11g with 2 nodes (same hardware & software configuration) I tried to inject packets using mac80211 (similar way as in packetspammer) Radiotap header contains only Flag=0 & Rate=1Mbps (total size = 14 bytes) However when I use wireshark to capture traffic, I discovered that each frame was sent twice: first time with 14 bytes radiotap header second time with 13 bytes of radiotap header (Rate omitted), so 54Mbps here. Is this a problem of ath9k or a default feature of 802.11 ??? Another question: if I set the FCS flag to send frame with all zeros FCS, the receiver reported frame as bad FCS, but still deliver it to upper layer. Why? I think the frame should be discarded ? I want to simulate broken phy link by jamming FCS. Is there any alternative way ? Hope some one can help. Thank you.
