Home Network IP Assistance

I have a device on my home network that always comes up as 192.168.31.194 and I’d like clear, actionable guidance to make sure it behaves exactly the way I need. Whether that means confirming the current configuration, switching it from DHCP to a static reservation, opening or closing specific ports, or simply tracing why certain services are unreachable, I want to walk away with a stable, well-documented setup.

Here’s what I need from you:

• A quick remote review of the existing router and device settings that involve 192.168.31.194
• Step-by-step instructions (or live assistance) to apply any fixes or optimisations we identify
• A concise write-up of the final configuration so I can replicate or revert it later

Because this is a home setup there’s no hard deadline, so we can schedule sessions at mutually convenient times. Experience with typical consumer-grade routers, basic firewall rules, and port-forwarding best practices is essential, but if you also know your way around simple Linux or Windows services that’s a plus.
