I am using TL WN722N in monitor mode. I am facing the problem of channel hopping though. It captures most of the packets (around 80 to 90%) on the selected channel but it hops all other 12 channels during the capture to make up the remaining 10 to 20% packets. I have been unable to make it sniff on just the selected channel for the whole duration. Is it something related to the RTL 8188 drivers? Or is it the fact that I use it on Raspberry Pi? The Alfa network AWUS051NH adapter works fine on the same RPi though.
