Per brostrend website documentation, this device uses Realtek RTL8812BU or RTL8822BU.

Per USB_WiFi_Chipsets.md these drivers require Linux kernel 6.2 or newer.

The current stable release for OpenWRT is 23.05.2 which uses Linux kernel 5.15.

Hi @wassupluke

I merged the PR. Thanks. I will probably go in and clarify the details.

Right now and probably until the 2025 version of OpenWRT, the only dual band, WiFi 5 or 6 chipsets that are supported are the mt7921au, mt7612u and mt7610u. A good way to think of it is that OpenWRT supports those chipsets, not that the chipset support OpenWRT.

OpenWRT moves up to the year behind LTS kernel each year so 2024 should use the 6.1 kernel. RTW88 made it into 6.2 so unless somebody backports the driver, 2025 it is. Now, the mt7921au was backported all the way to kernel 5.10 when it came out but there are Mediatek devs that work on OpenWRT. I'm not aware of any Realtek devs that work on OpenWRT. In fact, the USB support for RTW88 was not done by Realtek. It was done by a community member.

Maybe add info about the required kernel.
