Many shooter games are P2P-based and therefore leaves you at the mercy of the connection of the host - which is very often not great and tends to introduce a lot of lag issues. I don't think kill/death ratios are great indicators of whether or not there is a serious issue going on here - like I said previously, Broadcom's hardware acceleration module (which you suggested was the root cause of the issue) is used in more than just the RT-AC87U, leading me to believe this would be a widespread issue across any Asus router implementing it and not just this particular one and I've yet to see any major outcries from others with the same issue.
For what it's worth, I've never had a PS4 connection test take less than 8 seconds to complete and I have zero lag issues with hardware acceleration on, QoS on or a combination of both (on 2.4GHz wireless as well). I'd rule that out as a reliable test because - like I said before - it relies heavily on your connection to Sony's servers which are sometimes down or problematic more often than they work as expected.
1. my ISP sucks (i don't have a choice though), ask merlin he agrees.
2. Because of number 1 above I see things way before you and many others do.
3. I am not going to post what I already said so go back and read.
4. Also while lag is showing when playing I get stuttering etc..., whatever you want to call it, and this also goes away mostly when I get 4 seconds on that test, again you most likely have a great connection, I do not, as my #1 above.
5. It happens with NAT A on or disabled, it just takes up to 24 hours to show.
my question to you is why after a fresh reboot I get 4 seconds and no lag, but after up to 24 hours I get 8+ seconds and lag, on my tests, and I run then a lot before and after.
Also why is this changing, why am I getting 4 seconds for the first 24 hours then 8+ after a reboot of the router at any time of the day????
You can't tell me sony knows when I reboot my router, is that what you are saying?
You say you are getting 8+ seconds, do a reboot of the router and see what you get then.
