This is gonna be a really dumb thing on my part to bring up so I'm gonna preface this. Over the last couple weeks since the new update on warzone. I seem to get practically no aim assist. I went into the settings and triple checked everything. Everything is the same. I had switched to using my old Linksys router and it was doing great until it wasn't. So I switched back to my XR500 and seem to have no aim assist in game. It's a noticeable difference. 
Now when I bypass the router and connect my Xbox straight to the modem my connection on top of hit registration and aim assist feels amazing. But when I have the XR500 connected in between. It seems to disappear. My Xr500 is running .34 firmware. I have the spectrum gigabyte service. Brand new CAT8 cables all around. Checked all settings and nothing changed. I know I'm not a bad player either just a bit frustrated. 
I just want to know how I can fix that. Or get the same gameplay feeling such as when I directly connect to the modem.
I added my stats from last season. Since this season the stats are bugged. Just to indicate I'm not a bad player or on a delivery because I play consistently. I just don't know what it could be. 
 

Ok thank you @Fuzy

Ok thank you @Fuzy

Will do @Netduma Fraser I appreciate it! 

One thing I find interesting about this, the ISP. Spectrum always have things going on with their HUBs or MODEM and or Routers. If you're using spectrum OWN Modem or Router, this could also be something with that. As @Zippy and I noticed when it comes to Spectrum equipment. At the end of the day, what works for others may or may not work for others due to the way ISP handle the network and infrastructure is setup in your area. Now, what also might be a factor is the tech of the xr500. It does have pretty beefy hardware, along with the xr1000. One user theillestbeast consistently put out videos on the xr500 and xr1000 for a long while

No worries, got to do what feels the best for you, we'll be doing a big DPI update soon which may help.

That's right, yes it's the latest currently, we'll always pin the latest firmware to the top of the beta forum

Plug the modem in, wait for that to boot up properly so wait a few minutes, then turn on the XR wait a few minutes then connect but generally you don't need to do that as the factory reset/setup wizard would prompt it to get internet again. You can keep the Xbox connected and turn on when ready. I think that's probably a placebo effect as there is no networking reason that would be the case.

Welcome to the forum!
Generally when people mention having this problem in game, throttling their speeds severely using Congestion Control and forcing servers slightly further away with the Geo-Filter seems to help them. I could also give you access to the beta if you would like to try it?
