It depends on the chip within the adapter. Find a model that you like and research it online to find its chipset. Then search online for linux compatibility with that chipset. If it requires a custom kernel or drivers from the vendor then no, it will not work. If it has kernel support in Kernel 3.8+ then it should work fine.
I am looking to improve internet performance at home. Currently using an ASUS RT-n66U with the wifi power off and a ubiquiti unifi Pro AP. Thanks again
I have only seen one report of a USB NIC that works reasonably well; you might find it if you search the forums but I strongly recommend installing an additional PCI/PCIe NIC instead.
