That patch does not get you very much. It enables 5G at very short distances from the AP. The 2.4G band does not work at all. In addition, it apparently screws up the BlueTooth. Because it is a false fix, I NACKed it at wireless. Once Realtek publishes the real patches at linux-wireless@vger.kernel.org, I will push them to GitHub.com/lwfinger/rtw88.git.
