Did a search but couldn't find anything which seemed relevant.
I'm on BT fttc fibre and have a smart hub 2. I've recently got a ps5 and when I am playing online and my other half starts streaming on her tablet the latency is unreal. This did not happen on the PS4. I have looked through the smart hubs config and can't see anyway to set a priority on the devices or why this would change based on the advice.
Any ideas why this would have changed?
Can't find the setting anywhere? Could you advise where it would be located?
This mightn't be relatively helpful in solving your problem but I invested in a 3rd party router, I chose the TP-Link VR600 V2 for a good price. And not encountered any issues, it's been running smoothly since then. And it works with BT's /56 prefix for IPV6 which is a bonus
No lag spikes, no reboots. I can understand why the experts on the forum preach 3rd party alternatives as they're considerably better than the provided kit. I wish I did this years ago!
I did have the lag issue with the Smart Hub 2 until I swapped over to 3rd party kit.
*Edit* - I game on the PS5 myself and haven't encountered lag spikes since the switchover.
