Xbox one (wired to superhub 2) and 360 (via power line adapters). I've had 160+ latency on both since Nov and bops multiplayer is unplayable. Loads of dropped games Fifa on 360. Been passed from bband to third party technical for the last 3 weeks. I have spent my last two Friday evenings setting up port forwarding done by tech last night (remote) and xbone jumped to 340!!! I hope someone can help as I'm lost here. Also done dmz. Pc wired gives ping at 10 ms. All other devices are fine.
a multiplayer connection/speed test always shows Latency around 160 (ish), this is because the network test on your xbox one is tested against xbox servers in america, seattle. unlike a PC speedtest which is done against the closest server so hence why PC wired is 10ms. no matter where in the world you are the xbox tests against seattle servers..
