From what I'm seeing at the time your signals were checked, everything looks fine. And you said you're also not seeing any packet loss.

Are you running wireless, or through any router? ie. are you running wired staight to the modem?

Yes I am running a router from the UBEE modem. Netgear R6300 mixed reviews. the Ipad is wireless and I have tried both 2.5 and 5 ghz networks. I have taken into consideration that I am Facetiming to Australia, time of day, Network congestion etc. The only reason I am asking is when I use my iphone with ATT 4G LTE network the signal is much better and doesnt really do it. I have changed channels of the router. Made sure nothing is causing interference to the best of my ability and also tried changing the dns servers. I have no trouble with anything else. I think it must be on the other end. I think everything checks out here to the best of my ability I have checked everything. I just was wondering if I may have missed something. thanks

If it's just FaceTime, Apple made some changes recently -- so it may be that...
