PS5 IP PACKET FRAGMENTATION

[DavidCSmith]

Good day, 

Moved into a new property - Went with Sky - Managed to get everything in the house connected, Phones, Computers, TVs, Doorbells, And an Xbox. 

Been trying to connect my PS5 Has been an absolute nightmare. 

Problem No:1 - IP Packet Fragmentation - Router might not support it ? 

Problem No:2 - Download speeds - Dreadful - Getting 20-25kbps on test? 

Things I have tried - 

UPNP, DMZ, Port Forwarding, Static IP for the PS5, Changing the DNS over to "Google", MTU package size - shrucken and enlarged to all different sizes from different posts on different forums, Tried wired, tried wireless. 

My playstation sits - 5ft from the router, nothing blocking it.I blocked all access on the router apart from my laptop and the PS5 to see if it was interference. I've Reset both PS5 and Router. 

Nothing seems to be working - Then I've looked further into this and seen that there is a thing called MAP-T that "Could" be affecting this ? Can anyone lend any feedback, What, Why and how to solve this issue and it's very frustrating?

I've got a 900mbps Line - I get 600 on my mobile sat next to my playstation. 

Thank you,

@DavidCSmith Using the Sky Max hub, then automatic MAP-T equivalent to the CGNAT format and not ideal for gaming. Have a look at the link and try adjusting WPA mode with your mobile app. Shoulsd have been fine cable connected though. Also check and adjust the Broadband shield on you account products.

Hello,

Thanks for the quick response- 

I have looked into the post and tried implementing the solution mentioned

No luck with that either im afraid, keeps showing same errors linking to the "IP Fragmentation" 

Thanks,

@DavidCSmith Think you have to change a value on the PS5 to correct. Think by default probably got 1500, but with the MAP-T set it at the value of 1472 as per the link from sky at the top of the page.. 

Change Network MTU Value

This is something that you should never really need to dig into but it has been a solution to the problem for some people who are dealing with some unconventional configuration on their home network.

If you navigate to Network settings->Set Up Connection->Options button on active connection->Advanced Settings. You can scroll down and find that MTU is an option at the bottom of the page.
