Lag Issue - ISP or Hardware?

[Tizerak]

This is probably your issue. You generally won't see it during off hours, but during prime time & the hours surrounding it FIOS tends to get 20-50% packet loss to the Montreal servers. Next time it happens open CMD and type "pathping YOURSERVERIPHERE > c:\FFXIVping.txt" (without quotes) & hit enter. It runs a more thorough test checking all of the hops to see where the packets are dropped. If you're lucky it'll just be a wireless issue & you can grab an ethernet cord or power to ethernet adapter. If not, I've found tethering with my phone works way better than FIOS for ARR+Ventrillo/Teamspeak.

I don't use wireless at home just Ethernet. I don't see how 50/50 fiber is worse than 25/5 Xfinity cable internet I used to have. When I run tracert to Montreal and other IP's I always get a time out after the last Verizon hop:

Tracing route to bb6b6bb0.virtua.com.br [187.107.107.176]
over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms FIOS_Quantum_Gateway.fios-router.home [192.168.1.1]
2 6 ms 3 ms 5 ms lo0-100.WASHDC-VFTTP-326.verizon-gni.net [108.31.159.1]
3 7 ms 6 ms 7 ms T1-1-0-11.WASHDC-LCR-21.verizon-gni.net [130.81.171.36]

I can't/shouldn't afford the cost to turn my phone into a hot spot.
