Hi Aaron, my setup was 1 x qm2000 and 2 x fb3.
i set my notebook to static ip since i was using a direct utp cable, as used before. The qm did not show up so i fired up the network config tool and got firewall message about unkown network for which i allowed all traffic.
then i retried several times to connect to the qm. tried different utp cable, power cycle several times and finally i replaced it with a spare fb3.
now, back at home, i have no problems with this setup, replicated the situation and all works fine. I also had problems with the projector connected to the qm and afterward to the fb3 since green was not outputting the same level as when i started so i had to replace the projector also with a spare and was able to perform as expected. The projector works fine at home and the only difference is the temperature. I checked ilda cables etc... so don't have a clue what went wrong just happy to had a spare set at hand.
next thing i want to try is to put the gear outside when it gets colder just to be sure.
i did get several hw related error messages the week before, have screencopies available and lost connection to the qm what motivated me to bring a spare set ;-) proactive right !
i will send you a copy of the attachments which i also send to Bill and he advised to use a tcp packet sniffer but until now i have not been able to recreate the faulty situation (luckily).
