[plug] USB WiFi dongles ...

[Daniel]

Hi Bill and Plug
Please forgive my lack of knowledge 
I haven’t noticed any replies from others so ...

I read an article recently saying there were a lot of advantages to the iwlwifi driver from Intel

Unfortunately there don’t appear to be any USB wifi devices with Intel chipsets and this would mean the change to a motherboard that took an M2 wireless card and an Intel wireless card to allow the use of iwlwifi driver

Lots more work and costs but might this kind of approach be a solution?

Cheers

Daniel
