Hunt for atheros, out of the box mon mode supported by atheros, what more do you need.
Most stable shit ever and just works , I have one of those PCI cards around that is awesome but also I obtained a bunch of high end pci mini or whatever it is called, atheros chipts , these things can pump out 1 watt if it is power you are honrny for, I prefer modules that are stable but these seem to do both(for those who dont get the hint, you can put it in your laptop............really??yes)
I promise I will check the labels and post details if anyone cares (ubiquity iirc)
There are alfa cards out there with such chips.
I had a bunch of those rtl 'uberhaxxorcards' , they all sorta died on me trying to download a file which is nearly impossible.
They get hot for no reason , I had 1 replaced etc, dont get me fucking started on alpha ffs.
Tried different antenna's , distance , you name it I tried it.
Even used windows to see if it would matter the slightest, I'm pretty sure its worse.
THE DRIVERS BLOW, just saying.
