I have installed an intel 7260HNW dual-band ac wireless mini-pcie card in my beebox in place of the Realtek AC8821AE it was originally supplied with.

However after reboot the adapter is not shown in device manager. I have tried re-seating the card and cleaning the pins, plus clearing the cmos and re-booting all to no avail.

I re-installed the Realtek card and that was recognised/installed as normal.

So I'm wondering if there are any known compatability issues or if it's likely just a bad card?

I bought the card 2nd hand off eBay but before asking for a return I thought I'd ask the question.

My o/s is Windows 10 pro 64bit.
