Realtek 8812au / AWUS036AC Dualband USB3 wifi adapter?

JaydenLouis

Alfa Network AWUS036AC Long-Range Dual-Band AC1200 Wireless USB 3.0 Wi-Fi Adapter w/2x 5dBi Removable External Antennas for Extreme Distance Connections - 2.4GHz 300Mbps / 5Ghz 867Mbps - USB Cradle Dock Included - Standard's 802.11a, 802.11b, 802.11g, 802.11N, 802.11ac

It uses the Realtek 8812au chipset. From what i can find this is supported by freebsd After plugging the dongle into my pfSense box I can see it via dmesg :
ugen5.2: <Realtek 802.11n NIC> at usbus5
and usbconfig :
ugen5.2: <Realtek 802.11n NIC> at usbus5, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

But i cant see it via the pfSense frontend. I am presuming the fact that dmesg and usbconfig are showing the device means it is being recognized by the system.

Anyone got any pointers on getting it working?

I know a lot of people say dont use USB networking, but I am hoping to use these on SG1100's as well.
If there is no way to get this working, can anyone suggest a similar product (and price range) that will work (Dualband, AP and client mode)?

Thanks

Looks like it's not supported in 2.4.5:

[2.4.5-RELEASE][admin@t70.stevew.lan]/root: kldstat -v | grep rtwn
		307 pci/rtwn
		309 rtwn_rtl8192cfwU_B_fw
		308 rtwn_rtl8192cfwU_fw

But should be in 2.5, even in arm64:

[2.5.0-DEVELOPMENT][admin@2100-3.stevew.lan]/root: kldstat -v | grep rtwn
		172 uhub/rtwn_usb
		171 pci/rtwn_pci
		181 rtwn_rtl8821aufw_fw
		180 rtwn_rtl8812aufw_fw
		179 rtwn_rtl8192eufw_fw
		178 rtwn_rtl8192cfwU_fw
		177 rtwn_rtl8192cfwT_fw
		176 rtwn_rtl8192cfwE_B_fw
		175 rtwn_rtl8192cfwE_fw
		174 rtwn_rtl8188eufw_fw
		173 rtwn_rtl8188eefw_fw

Obviously at 802.11N only though.
If you get the actual USB IDs from that you can check it specifically:

....and now I see this was a cut and paste job from here and almost certainly spam!

Yeah most likely... Lets see if he still tries it after we have called him out..
