Latency issues through Xbox live

[fkrsai]

I've tried all the tests, ethernet cable, swapping from 5Ghz to 2.4Ghz, restarting the modem/router, etc. 

Latency is sitting around the 140 mark and has been for the last few days now. Will sometimes go okay for a few minutes but then spikes again. This is at all times of the day and even worse after 7pm. No devices are connected except for the xbox when trying to play. 

Does anyone know how to fix this issue?
