Good day. How to set up two WiFi cards rtl8812bu (usb 3) ?

Good evening @YudinIgor

This issue has come up before. We did some testing and came to the conclusion that these Realtek drivers don't support more than one adapter with the same chipset in the same computer. You can have many adapters and many drivers at the same time but all adapters have to use different chipsets.

While we were testing, we also tested to see if the same is true for Mediatek chipset based adapters and found that the Mediatek drivers support having more than one adapter with the same chipset. The adapters tested use the mt7612u chipset and the in-kernel driver.

I just added a new guide on how to setup a Bridged Wireless Access Point. You can find the appropriately named file in this repo now. It may contain information that may be helpful to you.

I also have a repo that provides a lot of info about USB WiFi adapters on Linux:
