Yes, downloaded from https://www.armbian.com/nanopi-neo4/, tried both latest stable buster and bionic image. When I typed dmesg it showed that it was looking for fw_bcm43438a1.bin in /lib/firmware/rkwifi/, but only fw_bcm43438a0.bin was there. I also checked the github repo https://github.com/armbian/firmware/tree/master/rkwifi, no fw_bcm43438a1.bin in there. Actually it can be found in /lib/firmware/ap6212/, but it seemed that the system was not looking into that position.

I used both buster and ubuntu images (Armbian_5.91_Nanopineo4_Debian_buster_default_4.4.179_desktop.img and Armbian_5.90_Nanopineo4_Ubuntu_bionic_default_4.4.179_desktop.img), both have no wifi, only show "device not ready". So I extracted firmware from official friendly desktop image and unzip to /lib/firmware/rkwifi/ and wifi works. I'm a newbie and hope this could be fixed properly soon. For those new to linux like me, download the attachment, extract everything to /lib/firmware/rkwifi/, reboot and wifi should be there. ap6212.zip
