I realize an MX100 maxes at ~750 Mbps, but we have one on Comcast's new gigabit coax service (along with a 250 Mbps coax circuit, in fail-over) and it just isn't working. The 250 Mbps works, the gigabit has high (25%-100%) packet loss and high latency, it fails over for one minute several times a day, and occasionally throughput goes to zero without failing over. Comcast thinks their end is OK (one pingplotter and continuous ping test at modem didn't reveal anything); they do think we're maxing the gig's up speed, 35 Mbps, but the 250's up speed, 25 Mbps, doesn't cause issues). The only other factors I can think of: the 250 Mbps circuit is extended from demarc to server room with coax (modem by router), the gigabit by fiber (modem at demarc) we have high internal traffic from security cameras, but it is VLANed off we're having other recent problems like computers not consistently finding printers, AD server, or wifi APs all of this - router, gigabit circuit, VLANing, cameras - are new. We don't have the skills to properly debug this, so we're going to swap parts, circuits, etc. to isolate the issue.
