Update: I made a mistake. The card I am using is the AWUS036AC (without the M). They look exactly the same but the AWUS036ACM is using a different chipset mt7612u. You can thank ALFA for this confusion.

Thanks for making this video man! I think the reason why people keep asking for 5g deauthers is because when you launch an evil twin and deauth every device from a router, most modern routers support both 2.4 and 5g and all the devices when kicked from the 2.4 band will just switch to 5g and the evil twin attack will fail. That's why you need a 5g deauth tool to kick both the 5g band and then a regular 2.4g deauth to complete the attack. I tried it on my new router and yes, without kicking both bands all my wifi connected devices with the exception of some old IoT stuff will just swith to 5g automatically. So this video is a huge help thank you! Looking forward for more tools! I actually recently bought your wifi rubber ducky and have been having weeks of fun making scripts for it. Great stuff.

It's super interesting to see how it works, with a small terminal we can end up with Wi-Fi for some reasons, such as: loud sound. Helps!

Just tried this out! It worked wonderfully! I managed to find a wifi adapter that met the requirements and was under 30$
