deauth-ing simultaneous dual band router

[jtam]

Hi all
I've searched the web for a similar problems but haven't had any luck with this in particular.

I'm testing a dual band router on my network that operates 2.4 GHz and 5ghz at the same time . Most mobile phones connect to the 5ghz band .

WhenI run a deauth (have tried MDK3 and Aireplay, and I have primed my dual band adapter using "band abg") it only disconnects the devices that are using the 2.4 GHz.

First off all I am unsure as to why it is doing this despite priming it to both bands. Secondly, I was wondering if there may be someone who can point out where I'm going wrong.

Any help would be greatly appreciated.

I am using the standard aireplay-ng code (or if using MDK3, using the usual MDK3 code just added a blacklist on it with the target AP Mac.

Thanks
