Hi Alvin, what shall I say, your hint worked like a charm! I can now connect to my access point just fine. Thank you a lot! If someone happens to find this through some search engine, here's some more info I picked up, partly on irc://freenode/#iwd: * When iwd is invoked with '--interfaces wlan0', then UseDefaultInterface is set automatically * The driver my system is using ("bcmsdh_sdmmc") has the same issue as the "brcmfmac" mainline driver, which, because of its issues, got set onto a blacklist. Then these --interfaces/UseDefaultInterface settings should not be necessary. But because my "bcmsdh_sdmmc" driver seems to be an out-of-tree one and goes by a different, the blacklist didn't apply. Again, thank you a lot, Alvin! Have a nice day everyone. Manuel Am Mi, 27.

[1] It run's a Yocto-based distribution with meta-tegra as BSP layer. [2] meta-tegra is based on the official nvidia-provided BSP called L4T (Linux for Tegra), which is available for Ubuntu only.
