Wireshark-users: Re: [Wireshark-users] Capturing 802.11 RSSI and TX Rate Values Using Ubuntu Linux

     I was using
ifconfig wlan0 down
iw dev wlan0 interface add mon0 type monitor
ifconfig mon0 up

which was working as desired for a while. However, now I am only picking
up packets of type "Other" when sniffing on mon0. Why is this the case,
and how can I correct it?
     Thanks for your help in advance.
