This driver looks like doesn't support "monitor" mode, does any one known about this ?

[yangjunfei123]

I tried to set wifi mode to "Monitor", but it prompts "Invalid argument"; if I set mode to "Ad-Hoc", then it worked. I jus want to know the chipset rtl8812 isn't support this feature from hardware, or this driver isn't support it.

The following is error message. [root@localhost Downloads]# iwconfig enp0s26u1u6 mode Monitor Error for wireless request "Set Mode" (8B06) : SET failed on device enp0s26u1u6 ; Invalid argument.

It is supported but the rtl8812au driver doesn't communicate well with tools like iw, as they use nl80211, take a look at this repo https://github.com/jekader/hostapd-rtl, it adds support for this type of RealTek driver to hostapd which I'm assuming you are ultimately looking to use.

Hi AaronMcHale when I run "airmon start enp0s29u1u8 " I got this error, got any idea with this ?

[root@localhost neil.yang]# airmon-ng start enp0s29u1u8 Found 5 processes that could cause trouble. If airodump-ng, aireplay-ng or airtun-ng stops working after a short period of time, you may want to kill (some of) them!

Monitor mode is supported in 4.3.22 version of driver.

If you're looking for monitor mode support that will compile on Ubuntu/LM, this version will get you what you want without updating kernel or gcc as required by other drivers that support monitor mode.

I've managed to get monitor mode working for an ALFA AC1200 running RTL8812au using https://github.com/Grawp/rtl8812au_rtl8821au on Kali Linux.

hey amadeuspzs, when i tried to install the driver it always gives me some errors.. I am using Kali linux on a virtual machine and i tried to install several drivers but most of them seem to get me errors. The first one I installed worked but this version doesn't support the monitor mode .. Can you tell me what i am doing wrong? Getting these errors:

i have the same problem as ( Florianwall ) :/ exactly the same errors.. ps: my adapter is TL-WN821N V5 ( TP-LINK)

https://github.com/aircrack-ng/rtl8812au supports monitor mode + injection

[curtiszimmerman]

Very nice! Thanks @kimocoder for the PR against the official repo and @astsam for the monitor mode support!
