Atheros is certainly network adaptor of some sort, i expect it is some software that is used that is not compatible with Windows 10, but as long as the drivers are in place it will work.
Atheros chipsets are a bit strange i have a wireless TPlink adaptor for my desktop which uses a Atheros chipset and i never really got on with it and I had problems getting one working on a laptop that some one updated from Windows XP to Windows 7 a while back. I use a home plug now for my desktop, now I found one that works.
Edge got no add ons at the moment and when it comes will anyone support it? I do not like edge, so even if I went back to Windows 10 and it had all the extensions support, I would not use it. i do not like the look of the Universal apps and that is what Edge is, but then I do not like Internet Explorer either and the last 3 or so versions looked awful.
