How much MTU ?

[Aiden2k13]

How much MTU do you keep PS4/XB1 ? My NAT is OPEN but sometimes I get dodgy connection , hence was asking.

The default 1500, I've never even paid attention to whether or not its changeable. This shouldn't really be a problem for you and if so you'd see it on your other devices. The only times I've run into issues with this are with some DSL connections.
