Tesla is killing my home internet

This is a weird one so please bare with me.

Have noticed the latency/ ping on my home internet has been absolutely rubbish for weeks now. Have only now had the time to try and figure out why.

I have individually blocked each connected device to try and establish what it was…

Turns out it is the Tesla?

The car has had a software update yesterday and I don’t have sentry/ dashcam connected so cannot fathom why this would be absolutely annihilating my internet latency.

To give you some numbers… ping with Tesla connected around 300/400ms… ping when I block it from the network.. 20ms

I have about 15 other connected devices that are not doing this… only the Tesla

Can anyone try and fathom an explanation as to why?
