On my previous router, I had it all setup so I go into iPhone > Files app > Connect to Server > and I had a 192 type smb address thingie setup so I could view certain Users’ directories (Windows elven11 laptop) and exchange files between the two devices and even make actual changes like deleting shit and creating new folders or renaming or moving stuff around.
But thats all gone now 😭
Please, so much My night depends on a reddy network
Go into the settings of that smb thingie on your iPhone, and change the address (192.168.etc) to match what the Windows machine says.
As for setting the static IP, I can help more if you tell me the make and model of your router.
