How do I turn on monitor mode in wireshark on windows in the capture options?

My modem log says "A device failed to connect to SSID (40:5E:F6:4C:64:BE) because it provided incorrect login information" lots of times. The SSID is my phones. I want to look in to it but I can't figure out how to turn on monitor mode in the capture options in wireshark on windows. What do I put in the field under monitor mode?

Sorry for asking a question like this. Any help would be appreciated.

See the Wiki page on WLAN capture and in 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).

I think you're running into the latter problem, your hardware\firmware\driver doesn't support monitor mode.

Thank you for your reply . I had read that. Is there a way I can verify this is the case? Is there a workaround?

I'm on windows 11 home 22H2 Wifi hardware: Intel Wi-Fi 6 AX201 160MHz

A workaround is to NOT use Windows and instead use another OS with hardware that is known to be supported. That may or may not help.

I understand all the parts in the "chain" have to support the function in order for it to work. Is there a way to check which part(s) is/are not?.

I found out it's the wifi hardware that doesn't support it. On the windows command line you can use the command "netsh wlan show wirelesscapabilities" to check.

Thanks for the help.

That's useful, I'll add that to the wiki page.
