What other clients are connected to the hub?
gaming traffic uses very little but any type of background downloads on the PS5 will cause an issue even though it limits it when playing.
Whats happing is the bufferbloat on those websites is they test your line and saturate your connection. They are not the best for gaining the best results, waveform never reads correctly for me for example.
there’s also the game server you are connecting too and with a BT router you can’t do much about that. Some routers use third party services to route traffic and some use geo filtering so you can see what servers you are joining or give you the option to join or refuse.
these also tend to have QoS and prioritise traffic to help lower latency. Of course you are best to use a separate modem like a HG612 or one of the vigor offerings if you went that route.
normally to prevent latency you would run PingPlotter and adjust QoS to achieve the desired results but let’s say you use for example a Netduma router you would set it up at around 70 to 80% of both up and down and when it picks up traffic depending on how it’s set up it will allocate part of your connection to prevent saturation. Other routers like Unifi use a basic up and down limit through fq CoDel which reserves a set amount like above but that will always reserve it and there is little control on internal traffic.
so lots depending on what’s going on on your network when you game plus the servers you connect too.
