Still no wireless, but one bit of progress. It seems that the kernel does *NOT* like using subdirectories below /lib/firmware. I copied the ucode file to /lib/firmware and changed the path appropriately before building the kernel. Now dmesg at bootup shows...

It's enabled in BIOS and the Gentoo minimal install usb stick brings up wlan0 just fine. In my first post, I listed what kernel settings I had set. Is there anything else required that I'm missing? After all these years of hard-wired, I'm still a newbie at wireless, so I could be missing something glaringly obvious. -- Walter Dnes <waltd...@waltdnes.org> I don't run "desktop environments"; I run useful applications
