PS5 IP packet fragmentation

Joining in

I recently got the Hub 5 which was entirely freshly installed, and it was great.

However, the past few days I've experienced extreme lag and packet loss when gaming and my upload speed is minimal. I get the 1g package and my download speed is usually 800-950mbps but my upload rarely hits 20mbps and is usually 10-15mbps. 

I've tried adjusting the MTU to no effect

I’m having the same issues Please help!

Same problem here but with a PS4 pro and a PS3. I noticed this about 4 days ago. Upload speeds were less than 1Mbps (down to 400Kbps). I've tried lowering MTU size, wired connection, modem mode, rebooting and factory resetting to no avail. Something must have changed with the network a virgin.

I'm sorry again to hear this @Ubik 

Can I just check, is this happening on any other devices or just the Playstations? 

The ip fragmentation issue only appears to be on the Playstations

Mine has stopped saying the IP fragmentation warning on the PS5 today 

Just been playing daughters Switch online and kept getting disconnected and packet loss, so it's not just on PlayStation 

Everything OK now, problem gone

Any fix for this yet? I've been having this same thing for months even had an engineer out and the issue is still here 

Hi JamieB1,

Thanks for using the Community Forums to get this issue with your broadband looked into, I am sorry if this has been causing some frustration 😥 

I have already taken the time to check your services on my side for any issues, however I am not seeing any problems. 

However, it does look like your Hub has not been rebooted in over a month, so this could be a cause for the issues. 

Rebooting your Hub can help poor connections as it resets the data and corrects any issues with the WIFI channels. 

Please give your Hub a reboot today and monitor it for a few hours afterwards, get back to us if you see no improvement and we'll check your services again 😊
