@18RayFYour case is uncommon but not unheard of. What stands out is that you're using DHCP, which typically operates with an MTU of 1500. However, your ISP is clearly providing an MTU of 1492, commonly seen with PPPoE, and when the MTU exceeds the limit set by the router, fragmentation occurs, which can lead to issues like the one you experienced. In other cases, this might manifest more noticeably, such as through packet loss. It is not an issue on the router side as the router uses the most common configuration. 
@KinGzzyMost of what you said isn’t even an issue; the time going backwards is literally just the DPI reading the packets, and as you are using the AI, which you are, it doesn’t tell you the most obvious thing, which is that IPv6 is disabled.

No, you can't do anything; you have to wait for him to pass the information on to a Firmware (Embedded) Developer.

Yep please can you ask for vlan routing also while applying QOS on each interface also please. 
Also not sure if people know but Vlans can help reduce max and 95th percentile latency , due to the fact that traffic is separated  on different logical interfaces, each with its own ingress queues and burst absorption. This means Wi-Fi airtime chaos (retries, aggregation bursts, uploads from phones/TVs) is contained inside the Wi-Fi VLAN’s queues, instead of blocking or compressing ACKs for your wired gaming traffic. When the flows finally merge they’re already smoothed and paced.

It's the WAN side yeah, so you're wanting it on the LAN side then? I can make the request to the team

That's the plan!

The Congestion Control aspect is codel & our own proprietary algorithm I believe

Do this:
Quit the application/game/client completely - including the game client from the System Tray - important! Remove device from the Geo-Filter If you're on PC then give it the PlayStation Device Type in the Device Manager Resync from the Geo-Filter Map menu Re-add the device to the Geo-Filter Set up the Geo-Filter how you like Wait 2 minutes Boot up application/game/client To force servers you need to do the following:
It's essential the Geo-Filter is enabled before the game client (e.g. Steam etc) if on PC or platform (e.g. Xbox, PlayStation) or the game have been launched. If you change Geo-Filter settings when you're on the game then you will need to restart the game for those changes to take effect, otherwise it will use the previous Geo-Filter settings and appear not to be working.
For settings ensure Ping Assist and Geo-Latency are disabled in the Geo-Filter menu that can be found by clicking ⋮ in the top right hand corner of the page and go to Settings.
Strict Mode should also be enabled, it is enabled by default so if you haven't disabled it you can ignore it. If you have disabled it or want to check it can be found in the same Settings menu as above or in Settings > Troubleshooting > Advanced > Developer Options depending on your firmware version. Fast Search should also be disabled which it is by default so can be ignored if you haven't changed it, otherwise this can be found in the same place.

Okay good to hear, thanks for the update, I'll pass it on to the team to investigate

As in typically even in GPU for Pc most people don’t upgrade every gen unless massive improvements for example 20-30 series had biggest improvement and 30-40 and 50-60 series  raw performance isn’t a lot more .
obviously time between the router models are longer as we see when the Duma R3 was released vs R2. So when we have a R4 released if the improvement is 10% vs R3 most people wouldn’t see a point to upgrade for  whereas if the improvement is a lot higher around 40% or more many people will purchase due to the price to performance also despite being more expensive than. A R3 Hope it makes sense 

Yes that’s true but a CPU has cycles to inspect and forward packets etc a NPU has parallel pipelines to process in nano seconds vs microseconds preventing spikes when loaded  , also provides advanced security with barely any latency compared to a CPU . if added it will be beneficial but if you guys can’t it’s fine I’m only listing what I thjnk can have a big enough difference 

Thank you for your help

Yes that worked thank you for your help 

Thank you I done that but I think everything is fine as I have recieved a text message regarding schedules delivery for my router but I still don’t understand why I never recieved an email for order confirmation.
