You're welcome. I like rtw89 supported cards very much for my home AP. I'm
glad I'll now be able to use multitudes of them in one router. :-D

Thanks for upstreaming and maintaining the Linux driver. My AP has been
working solidly for me since the driver gained AP support, which is
great, especially given how much development it's receiving.

Best regards,
