No, but at least wired ethernet works: # dmesg|grep -i rtl [ 14.614875] dwmac-sun8i 1c30000.ethernet eth0: PHY [stmmac-0:01] driver [RTL8211E Gigabit Ethernet] (irq=POLL) FWIW: # uname -a Linux <snipname> 5.10.0-3-arm64 #1 SMP Debian 5.10.13-1 (2021-02-06) aarch64 GNU/Linux # uname -srvpio Linux 5.10.0-3-arm64 #1 SMP Debian 5.10.13-1 (2021-02-06) unknown unknown GNU/Linux Comparing the two above, is an "unknown" a minor bug in uname, or user error?

This is a "hat" type small (SDIO?) Wifi/BT card plugged onto the board, not a USB device, and the Pine A64+ hardware is dated March 21, 2016. Is there something I can (reasonably) do to help move this module thing along, or is the best advice to just wait more patiently? On a related topic, what would it take to make the Pine Debian installs more nicely packaged, like the Raspbian installs? (Thanks, Gunnar!) Thanks RobJE, Paul Wise, and Arnd Bergmann!
