Interesting, OK thank you. I'm afraid I don't know what more we can look at until we can get you a new firmware to test. We're currently testing a release candidate for the XR500, so hopefully we should soon be able to get that released finally. Apologies for the inconvenience!

Presume he means checking the stats in previous COD's vs. the in-game performance of some of these players.
I watched back some footage - it appears on the times I do bad, to be fair, most of my shots are landing. Whilst this doesn't account for any timing/sync differences that lead to "super bullets" where I get instamelted, it does at least point to something else going on.
What's happening however is the gun-kick/recoil, especially horizontally, is wild. Could recoil have been adjusted in the most recent patch? I've retuned my attachments now to focus on recoil and did notice an immediate improvement.
However, this still doesn't account for how I was able to laser people with the exact same weapon for a full week prior. Unfortunately, I don't save any gameplay of my good games - only bad games, so I can't compare the two. I'll look to do this going forward.

Thanks Liam,
The connection to the dashboard also tends to glitch out when I'm getting the drops - if I'm already connected it'll show the internet status as "connected" on the dashboard when the drops are happening, but nothing on the dashboard will update and if I try to refresh, it'll just show me the spinning "loading" icons until it reconnects. This has been the same behavior pre and post DHCP changes.
Will try the above on the next drop and report back

Exactly my experience ^. I've had games where I can burst 5 bullets into someone knowing I've got the kill but the past day or two I'm shooting 20+ bullets at range to get a kill. I'm jumping around corners pre-aming/firing knowing someone is there but they kill me instantly lol. Watching the killcam it just shows me jump in slow motion, fire a shot or 2 while they pump me with lead. Defnitely feels like I am synced to the server half a second behind everyone else. Looked up people's stats and these negative kd players seem like they're 3-4KD players in previous cods
Who knows what they're tweaking/manipulating network side. If it was the servers performing bad then it should be affecting our opponents as well but they seem to have a huge advantage atm

Thanks both for the answers. @Zippy - I'll read into IPv6 to get a better understanding of what's what, thanks for the avenue.
@Netduma Liam here you go. The prioritized device with 11 on the flower is my gaming PC, same device on the traffic Prio which I've tagged as a games console.
Another one - Hula and 4oD have both stopped working on the TV, but Youtube and Netflix are fine. Coincides exactly with the router installation. Any thoughts?  
Thanks!
