I have a panda wireless pau09 WiFi card running on ubuntu 14.04/raspbian jessie It uses the rt2800usb driver
I can get it running in monitor mode without any problems. For example, If I run airodump-ng, I see all access point AND clients around.
If I take it out from monitor mode and then put it back into monitor mode again, the card doesn’t work good. For example, if I run airodump-ng it sees ONLY the access points around but it doesn’t see any clients (I repeat, this only happens the second time in monitor mode. In the first time I can see clients).
If I remove the usb dongle and reattach it, it works ok again (the first monitor mode).
This happens on all non-Atheros chipset cards including alfa AWUS036NEH, edimax EW-7811UN, etc..). On Atheros based cards, this doesn’t happen.
QUESTION 1: Is this problem known to anyone?
I thought it might be a driver issue so I tried to reload the driver with:
sudo modprobe -r rt2800usb sudo modprobe rt2800usb (never got here..)
But the computer gets stuck on the first command.
QUESTION 2: Is there any other way to reload the driver?
