One thing to be absolutely sure about is that the device is on a hardware
compatibility list (hcl) or has positive Linux reviews.. I don't use such devices
but in my experience, a device needs to be shown to work reliably with a kernel
version, by more than one person, hence the hcl. I also like to shop (online) for
products where customers can review products, looking for Linux users.
Time spent on compatibility is far shorter than time trying to get some device
with a unknown chipset working.
