According to Sony, the PlayStation Network should be up and running now. However, we’re still seeing reports of gamers who can’t get online.
While PSN servers might be running fine right now, there can be an issue of actually connecting to them. There is a little trick that might help that.
If you still can’t connect, go to your Internet Settings, chose the Manual Settings, and set the “MTU” to 1473 or 1476. This should remedy the problem of connecting to PSN.
Why change the MTU? As Redditor “disambiguated” explains: “The GRE tunnel overhead is 24 bytes – hence, changing your MTU from 1500 to 1476 ensures that large packets make it through to the servers.”
Eventually, Sony will change the MTU on their edge routers to 1476 which will help get traffic through. In the meantime, you can do it yourself in the PS4’s Internet settings.
If you’re still having trouble connecting, try setting the DNS to 8.8.8.8, which is Google’s public and very reliable DNS (you can also try the DNS address 8.8.4.4).
This should help you get back online and gaming in no time. Let us know if the trick works or you!
