So from this I read there is :
VM Hub 5 in Modem mode >>> a New Router >>> Sony PS5
Since the New Router was installed have you restarted the PS5 so its pick up a DHCP IP from the New Router ?
What does the PS5's network tests report ?
Thank you for your response
Yeah I've restarted it. I had the exact same problem with the other router. I'll turn the ps5 on it'll connect to the internet but struggle to sign into the playstation network straight away. But if i switch between wifi and wired or wired and wifi, it'll sign in straight away but still not be able to play any games online.
