Hi everyone!
I am running CHR over KVM as my home router.
In case of virtual, PCI and PCI-E Ethernet adapters everything works fine for a now.
But I'm curious about run some PCI-E wireless card, especially 5 GHz with n/ac.

I've tried my TL-WN881N - RputerOS could recognize it as wireless interface but can't run and crashed system after few minutes ((

I've tried to find compatible hardware list, but currently it is available only for RouterBoard at official wiki.

Is there any supported wireless hardware available in CHR?

There is no virtualization support for WiFi cards in chr. You can use chr as capsman controller and use other mikrotik devices as access points.
