Hi. I’m looking to replace my ageing USB Wi-Fi Adapter (Netgear WN111v2) that has served me well and always worked out of the box.
I’m on the hunt for a new Wi-Fi adapter that’s affordable (ideally < £20), dual band (2.4 GHz / 5 GHz) and will run on Ubuntu/Linux “out of the box” without worrying about drivers (in other words, preferable to have ‘free’ or ‘open’ firmware and integrated into the kernel)
I’ve had a deep search already, but I could be looking in the wrong places… 
Is there such device out there? Or any brands/chipsets to avoid?
Thank you in advance.
