"Partial Service" & "Synch" issues reflect typical SNR(Noise) which hopefully @ForumTeam / @ModTeam will clarify/confirm (or disagree) and arrange Tech visit. You've probably rebooted already(many times 😛 ) but this may give a temporary fix to TBB/BQM as well but essentially I still maintain you need to implement an alternative BQM host (eg f8lure.mouselike.com) to avoid potential false positives due to reasons stated in my previous post?
FWIW: Many of us (SU's/Triallists) have used SH3/Hub3's continuously since it's public limited beta in Sept2015 thru various/numerous firmware versions and some have also experienced SNR/Noise as consequence of Network/Infrastructure upgrades. "Noise busting" via Networks group can be a tedious and protracted exercise as it's essentially unique for each of 1000's of nodes in the country! Ergo: Common symptom but numerous resolutions.
