When I plug it in after boot, I get this in dmesg: ugen0.5: <Realtek 802.11ac WLAN Adapter> at usbus0 rtwn0 on uhub0 rtwn0: <802.11ac WLAN Adapter > on usbus0 rtwn0: MAC/BB RTL8821AU, RF 6052 1T1R NOTE that it self-identifies as 8821au rtwn0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps rtwn0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps rtwn0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps rtwn0: 1T1R rtwn0: 11na MCS 20MHz rtwn0: MCS 0-7: 6.5Mbps - 65Mbps rtwn0: 11na MCS 20MHz SGI rtwn0: MCS 0-7: 7Mbps - 72Mbps rtwn0: 11ng MCS 20MHz rtwn0: MCS 0-7: 6.5Mbps - 65Mbps rtwn0: 11ng MCS 20MHz SGI rtwn0: MCS 0-7: 7Mbps - 72Mbps wlan0: bpf attached wlan0: bpf attached wlan0: Ethernet address: 08:36:c9:1b:08:de firmware: 'rtwn-rtl8821aufw' version 111: 27804 bytes loaded at 0xffffffff82913000 # lsusb Identfies it as 8811au (but this is AFTER it loaded firmware) Bus /dev/usb Device /dev/ugen0.5: ID 0846:9052 NetGear, Inc. A6100 AC600 DB Wireless Adapter [Realtek RTL8811AU] And on the motherboard I have a similar chip: none6@pci0:2:0:0: class=0x028000 card=0x831a103c chip=0xc82110ec rev=0x00 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8821CE 802.11ac PCIe Wireless Network Adapter' class = network but the motherboard device is NOT recognized by rtwn driver. I built both rtwn_pci and rtwn_usb into my kernel. The rtwnfw man page lists device rtwn-rtl8821aufw, but doesn't list a device rtwn-rtl8821cefw I'm hoping in the near future the motherboard device becomes supported. -- FreeBSD FreeBSD 12.2-RELEASE-p3 FreeBSD 12.2-RELEASE-p3 r369327 Special amd64 HP-Slimline 290-p0014 Desktop Using integrated UHD Graphics 630 Built drm from /usr/ports/drm-kmod
