I am able to sniff 2.4 and 5Ghz with it but when I run aireplay command on a 5Ghz frequency I always get this error message ” no such bssid available”.

note: I have no issues when executing aireplay command on the 2.4ghz range.

Hi!
Which are the exact commands used to set it in monitor mode?
Can you share a screenshot with the airodump command used and the result please?

Thanks!
Diego

Hi Diego,

Thank you for replying. This may sound silly but I seem to can’t find an option to upload screenshots.

Hi!
You can upload them to any image hosting service and share the link here or use the IMG tag to embed the link into html code.

Hi Diego,

These are the commands I used to set monitor mode:
1. Iwconfig
2. Ifconfig wlan0 down
3. Airmon-ng check kill
4. Iwconfig wlan0 mode monitor
5. Ifconfig wlan0 up
6. iwconfig

Hi!
To fix this just run the deauth attack WHILE airodump-ng is running against the target network as shown in the course, so run airodump-ng using the ​–channel ​and ​–bssid ​arguments against the target network, keep it running, and run the deauth attack from another terminal window.​​

Let me know how it goes!

Hi Diego,

Can I do attacks on both frequencies (2.4Ghz & 5Ghz) at the same time using this adapter?

Hi!
The easiest is to have 2 different adapters to target each band because any adapter will work better if it targets 1 band at a time.

What you can do is create several virtual wireless interfaces from wlan0, and run each one of them against a separate band, keep in mind there’s a very HIGH chance of this failing but you can try it anyway, so first do
ifconfig wlan0 down
to disable our interface, then enable monitor mode on it like so
iw wlan0 interface add mon0 type monitor
iw wlan0 interface add mon1 type monitor
This will create 2 new interfaces for you in monitor mode, mon0 and mon1, which you can use in different terminal windows to launch de-auth attacks against different networks.

Greetings!

Hi Diego,

Thanks for providing me this information. I’ll purchase another wireless adapter.
