Professional documentation of my home network — the same format an IT support tech would produce for a small business client.
Every entry-level IT job posting asks for "network documentation experience." Most candidates have none. This repo is the smallest possible proof I can produce that documentation.

- Encryption: WPA3 (or WPA2-AES if router does not support WPA3)
- Guest network: Isolated, no access to main LAN, 12-character password rotated quarterly
- Router firmware: Auto-update enabled, verified running current version as of (date)
- Default admin password: Changed from factory default to 16-character random string
- Understanding the difference between LAN, WAN, and guest networks
- Reading MAC addresses to identify unknown devices
- Configuring static IPs vs DHCP reservations
- Documenting for a future maintainer (my future self counts)
