Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Thanks in advance.

Seems like there's no in-tree driver support.

A quick google shows that `rtl8812au-dkms` might support it.
0bda:a811 is not in it's usb_device_id table, so you need to manually edit it.

[Cristian Aravena Romero (caravena)]

Hello Kai-Heng,

Which file should I edit and add the information "0bda: a811"?

[Kai-Heng Feng (kaihengfeng)]

Under os_dep/linux/usb_intf.c, struct usb_device_id rtw_usb_id_tbl[].

[Cristian Aravena Romero (caravena)]

Hello Kai-Heng.

Can you create the .deb package with the correction? for me to download and install it.

So tell you if it works.

[Evgeny (evgeny-k)]

I have the same bug with same vendor/product id.

Is it useful, about patch under os_dep/linux/usb_intf.c, struct usb_device_id rtw_usb_id_tbl[].
for 0bda:a811?

At the line 320:

{USB_DEVICE(0x0BDA, 0xA811),.driver_info = RTL8821}, /* OUTLINK - Edimax */

This line was added 3 years ago, why doesnt work from box? May be is it wrong patch?
