But in a few weeks I might; I'll keep it in mind = :) I got LEDE 17.01.4 installed by going from: 6.1.7 -> 6.0.6 -> 6.0.6 beta = -> 6.0.4 (unsigned) -> lede-...-squashfs-factory.bin Surprise surprise, it doesn=E2=80=99t reproduce in LEDE, so it=E2=80=99s = something in Ubiquiti's stuff or a fix they didn=E2=80=99t pull in. Unfortunately I have to test with AirOS, but I=E2=80=99ll just have to = repeat all my tests with LEDE too so we can all enjoy looking at the = difference. :) Here=E2=80=99s hoping the flash back to factory firmware = goes ok. Thanks for the suggestion!=
