MTU PS4
Hello so I’ve changed my mtu on PS4 and on my XR500 I’ve expericed about 10% speeds upload and download and and have experienced a little less latency but I am just not satisfied I do get the router m...
Well Mtu 1473 has been proven to uncap speeds, on ps4 I’ve done 2 sets of {5 round tests for both mtu 1500 and 1473, lower mtu in general is proven to lower latency and if it is not actually lowering latency then I am recieving benefit of about 30-60 more download speeds im here to basically understand how to test for optimal mtu if there’s nothing to really test it then nobody really knows does the xr500 support packet fragmentation or does my ISP (Xfinity) or my modem Cisco DPC3941T
For MTU values, ask the ISP for whay they suggest. MTU valules are mostly based on ISP service, Most cable ISPs use 1500, DSL vary between 1472 and 1492.
Also your ISP modem is a gatway router. Having this in front of your XR series router will effect performaces and connections as well. It's not recommended to have two routers on the same line.
Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the NG router gets from the modem.

- Yea I already have my gateway in bridge mode and Comcast has told me to run a ping test in CMD to fun the lowest mtu without fragmentation which is 1472 And they said that it’s more then likely going to be my optimal mtu but if need be add to he 28 bytes
