Yeah but for QoS you want to prioritize only the in game data. The rest doesn't matter.

That is weird. It changed for me when I went from my PC ICS connection to test with wireshark back to directly plugged into my XR500.

The difference between having the source port changing is between open and moderate NAT. Basicly is you have open NAT source is always 3074 (on PS4) If you have moderate NAT the source will be in the range 62000-65535. You can go into the network tab in MW and display the external IP, it will show the port its using. 3074 or 6xxxx.

I have found the port ranges also change with your setup. Basicly OPEN NAT = SRC 3074 Moderate NAT = SRC 62000-65535 anywhere in there Also it might be coincidence but I was playing on my alt account with crossplay on, and it seems like the PC players were unkillable. So I turned that off as well.

These ports mentioned in the starting post don't work. I have UDP SRC 62000-64000 and DST 31000-45000 and the reverse rule into QoS at the moment. For some odd reason I found some communication with the datacenter (in my case Amazon Singapore) at 30110 and 30120 while just sitting in the lobby. With the above ranges it turns on QoS only from the moment it finds a lobby until you return to the lobby. There it stays on for a minute until it doesn't detect any traffic and then switches off. I can't say that it makes a difference though.

XR500 is a bit better than the XR300 but it depends heavily on your usage. If you use a lot of wifi, XR500 is better, if not and you use all wired you will most likely not see much benefit. The speed problem you have has to be a software of configuration issue as both WAN and LAN ports on that router is 1Gbit, or an issue with other parts of your setup. For reference though, have a look in your settings if all is right. Go settings > monitoring > statistics and look at your LAN connection. It should say 1000M/Full. If it says 100M/Full then that's your issue. You might need to try another ethernet cable or redo the connections. Some routers can be sensitive to the type of cable. I had one cable with a bit of damage once, on my ISP router it would drop to 10M/Full, on my XR500 it would drop to 100M/full. After cutting off 10cm and redoing the connector it went to 1000M/Full. These speeds get negotiated on signal strength as far as I am aware so that's why it can vary between devices. I just noticed while looking that up that my PS4 on XR500 drops to 100M/Full in rest mode, as soon as it wakes up it goes to 1000M/Full. So it might be a software glitch but I would investigate the physical cable first. Cable needs to be Cat 5E or higher for 1Gbps. The reason I suspect the cable is because usually when it tops out around 100 it's an issue with that. 100M needs 2 twisted pairs and 1000M needs all 4 twisted pairs. If there is an issue with one it will drop to 100M.
