Description cwf-ml 2019-07-24 22:25:56 UTC
The rtwn driver fails to recognize a RTL8821AE WiFi device.

# pciconf -lv pci0:1:0:0:
none0@pci0:1:0:0:       class=0x028000 card=0x882110ec chip=0x882110ec rev=0x00 hdr=0x00
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8821AE 802.11ac PCIe Wireless Network Adapter'
    class      = network
# kldstat | grep rt
 7    1 0xffffffff82661000     d610 if_rtwn_pci.ko
 8    2 0xffffffff8266f000    24a08 rtwn.ko

Thats a builtin wifi device in an ASRock Beebox barebone. 

It was my understanding from the man page that upgrade to 12.0 should enable that support, but it doesn't.

I just submitted a new report that also contains a patch I wrote for a different device in the same class. It may or may not be of interest to you. bug #239795
Comment 2 Andriy Voskoboinyk freebsd_committer 2019-08-12 07:52:53 UTC
Nope, this is one is not yet supported; 12.0 includes support for USB version of this chipset (RTL8821AU), not for PCIe (RTL8821AE).
Comment 3 Glen 2020-08-24 10:15:23 UTC
Same issue here, I am eagerly awaiting for a patch / update which supports the RTL8821AE pcie mini card.

Is this being worked on?
