rtw88_8821ce enable repeater mode. How?

[Yuriey1]

Hello!
I'm trying to achieve repeater mode on my RTL8821CE PCIe. I'm doing this on Ubuntu 24.04 Server. The distribution comes with the rtw88_8821ce module. This module does not provide valid interface combinations. Tell me, please, is this functionality not yet implemented? If not, is it planned for implementation and when?
And if it is implemented, then please tell me how to enable it?
Thank you.

The functionality exists but it's only enabled for RTL8822C. I think it should work for RTL8821C and RTL8822B as well, someone just needs to test it.

If I understood everything correctly, then repeater mode cannot be enabled on the rtl8821ce, right?

[dubhater]

It can be enabled if you apply the patch I posted above.

[dubhater]

I applied the patch. You can just pull now and test.

[Yuriey1]

I have already applied patch and tested the module. The AP is up and running, but I was unable to connect to an external WiFi point with the client. I don't quite understand why this doesn't work on Linux, because... on Windows, the same card can work in dual mode. We checked.

[dubhater]

Probably it's the driver's fault.

[Yuriey1]

If this is a driver error, how can I fix it? Maybe I can somehow help you with this?

[Yuriey1]

I would like to add that the AP and the client work fine separately. They just refuse to work together.

[Yuriey1]

Probably it's the driver's fault.

How to fix driver's fault?
