@star34 Do not worry with any WAN settings, WAN is Wide Area Network ~ internet and does not interest you at all for local play.

To me "192.168.0.1" looks like a default router address for many brands and likely it isn't an address of the device you have server running on, so maybe check again.
I'm probably bad at explaining maybe check this guide how to set up your lan as well as this one which has psp specific info.

I kind of feel that we have soo many of those adhoc guides and they're soo detailed that the amount of info might be a bit scary and lead to extra confusion and potential problems. You probably already read them and maybe took some settings from the guide which will be different for you, because if you understand some basics all of those guides could be simplified to short "run an adhoc server app on one device and use that device IP as a server address for all clients(ppsspp/psp)". That's really it at least on LAN, WAN has problems related to distance, connection quality, firewalls none of which really matters for local network which by design should be instant fast and simple.
