Unable to transmit arbitrary frames in the 5GHz band #20

Closed bryancoxwell closed 8 months ago

bryancoxwell commented 8 months ago

Hi,

I'm attempting to transmit arbitrary management frames (beacons/deauths/etc) using a Panda PAU0C, however they appear to be getting dropped when the card is tuned to any channel in the 5GHz band. Running a packet capture on the transmitting interface shows the packets being sent, but running a packet capture from a nearby device tuned to the same channel shows that they aren't actually being transmitted. When I tune to any 2.4GHz channel I can see the frames being transmitted though, so (as far as I can tell) these aren't malformed frames.

I'm using Debian 11, the Panda PAU0C, and I've tried various programs such as MDK4, aireplay-ng, and some custom scripts with no luck, and I'm not getting any error messages of any kind. Is this a bug, a limitation of the driver, or something else entirely? Any help would be greatly appreciated!

After doing some more research I've found that this has to do with regulatory domains and has nothing to do with the driver.
