    I have 4 different models of Panda USB WiFi adapters (PAU03, PAU04, PAU05 and PAU06) - all using the very same rt2800usb driver on Kali 1.1.0 / ARM.

    Question: does your Edimax EW-7711UAN exhibit a lot of "Tx excessive retries" and "Invalid misc"?
    All my rtl2800usb cards listed above do, and they also exhibit very unstable throughput, which drives me crazy because I can't get to the bottom of it :(
