Originally, the result was identical to my last email, including the WARNINGS. The .config I use is configured for a fully RT PREEMPT kernel, which I wondered if that was why I was receiving the WARNING. So I configured it as a Low Latency PREEMPT Desktop without the RT_PREEMPT and that eliminated the WARNING. However, still no 6Ghz networks. The firmware I'm using is straight from kernel.org GIT and I do a 'make install; make dedup' to install it. I believe it should be good. Attached is the latest log file. -Walt
