I have been able to enable my device to monitor mode via WlanHelper. I went into Wireshark and on the home screen the wifi activity is shown. When i go to Capture>Options, the checkbox under the Monitor Mode column does not allow me to check it. I don't know why it's doing this?

If I double click the wifi interface in question it starts capturing, but I haven't seen any other traffic other than my own.

I am assuming something is wrong here and I need to enable monitor mode in WlanHelper (which I've done), and enable monitor mode in Wireshark?


I have noticed that if I enable Monitor mode in WlanHelper, then restart, the device sees all the wifi networks to connect to. But restarting the pc like this puts the device back into managed mode.

So if I don't restart after enabling monitor mode and then go into wireshark- monitor mode is checked, but, the device does not see any wifi networks so is down and there's therefore no activity.

I would like to know how I can get my device to see wifi networks to connect to when it's in this situation? If I can do that it should all work properly.

Have a look at the Wiki page on WLAN Capture and particular the note:

Unfortunately, changing the 802.11 capture modes is very platform/network adapter/driver/libpcap dependent, and might not be possible at all (Windows is very limited here).
