Reatlek 8821CU Cannot put device in monitor mode
Closed this issue · 4 comments
Hi, I am trying to make OWL work on my USB Wifi Adapter which is based on chip Reatlek 8821CU. I have already installed driver on it, with "CONFIG_WIFI_MONITOR" option on.
However, when I am trying to activate OWL with command sudo owl -i wlan1 where wlan1 is the corresponding interface, I get the error of
ERROR: Error while receiving via netlink: Operation not supported
ERROR: Could not put device in monitor mode: wlan1
ERROR: could not initialize core
even though I have turned on the monitor mode by using iw. Here is the output of sudo iw dev which shows that I have monitor mode turned on:

I am not quite sure what happened to make this not working. Any help is appreciated, thanks.
Please read #9 (comment)
Hi, I do not think that my problem belongs to the situation described in #9. As you can see in my description, the card I am using is actually capable of active monitoring mode.
If that is not clear enough, here is the relevant content of using iw phy phy1 info:
Supported interface modes:
* IBSS
* managed
* AP
* monitor
* P2P-client
* P2P-GO
I appologize if I am misinterpreting anything.
There is no mention of active monitor mode in the output.
Hi, sorry, my bad.
