After using Blender without any WiFi connection, will cause it to glitch and make your screen constantly respawn in the same exact position you were last time and make it impossible to rotate/move something without making it go 33k miles away. Tried to re-install Blender again, and it still doesn't reset my work.
Blender does not use your network connection, so it's unlikely to be related to Wi-Fi.
It may be that the center of rotation in the viewport is at an odd location. In most cases you can select an object press Numpad . (View Selected) to fix that.
Just for check possibilities.
Could be what you're disabling the WIFI with a Fn + Number key? Maybe you changed the workspace or overlays or something in that file with the character?
You tried to Reset to Default the Blender Environment?
If not, delete your blender preference and settings folder on your system:
[BE CAREFUL THIS FOLDER CONTAINS YOUR PREFERENCES, SETTINGS, THEMES AND INSTALLED ADDONS]
