## Resource

The hosts document a real-world attempt to rebuild a small office network using Linux-based hardware and OpenWrt. They navigate unexpected hardware failures, bridge instability, and the complexities of managing remote connectivity.

## Highlights
- Main idea: Rebuilding a network around Linux-based hardware to gain full control over the entire stack
- Failure mode: Unstable network bridges caused by USB power management issues on MiFi connection hardware
- Practical takeaway: Using LLM-based TUI tools like OpenCode to rapidly correlate system logs and identify kernel-level issues
- Practical takeaway: Implementing decentralized VPNs like Nebula to establish reliable, bidirectional SSH access
- Practical takeaway: Utilizing Android tablets with web-view kiosk software as low-cost, dedicated Home Assistant dashboards

## Topics

Linux Networking, OpenWrt, Home Assistant, Nebula VPN, Network Troubleshooting, Open Source Software, Embedded Linux, IoT Automation
