As Zennon said above do the PingPlotter test to see if Anti-Bufferbloat is working or not. Are you actually getting lag or just hit detection? Have you moved your Geo-Filter to force a different server?
I ran a pingplotter with sliders at 70 and started a movie stream and graph was fine, just the usually 2-3ms increase.....so I have put my xr in AP mode behind my R1, connected my xbox to R1 set geo location and had some great games. Zennon was on for a few of them and i got a 38-6 score on 1 of my games. I am at a loss to what it is as my gaming experience was totally different to what it was on the XR...........could it be the hotfix version on my XR?
