Thanks for your advice, but I've done countless factory resets in the meantime. As a habit, I usually do completely clean installs when upgrading to a next release (even with alphas and betas), including factory resets, power cycles, the whole ritual. Just to make sure I don't post issues that are actually user errors (in other words: to rule out I screwed something up). I've tried everything anyone suggested around here, but Adaptive QoS just doesn't work anymore. The 380 branch was the last branch where it worked flawlessly, but as ASUS felt the need to make more parts closed-source, starting with 382 and now 384, my QoS died and never came back to life (yet). I don't want to roll back to stock firmware, even though that would give me an opportunity to reach out to ASUS for support on the matter, but that way I would loose way too much functionality. As my bandwidth is beyond sufficient (overkill basically, we're not heavy users) and Eric as other matters to attend to, I decided to let it be. Hopefully it gets fixed in one of the future GPLs. But with every next alpha/beta/final release I can´t resist to give it another try
