Guides & How-Tos
Practical guides, how-tos, and field notes from our off-grid, mobile, and remote system work.
Improving LTE/5G Performance with Manual Band Selection on Teltonika Routers
When a Teltonika RUTM50 or RUTX11 picks a poor LTE/5G band on its own, locking out problem bands one at a time can noticeably improve speed and stability at a fixed location. A step-by-step method using the RutOS web interface.
Setting Up a Guest Wi-Fi Network on a Teltonika Router (RutOS)
A step-by-step, GUI-only walkthrough for adding an isolated guest Wi-Fi network on a Teltonika RutOS router — a separate SSID and subnet, firewall rules that keep guests off your private LAN, and a bandwidth cap so guests can't swamp the connection.
Understanding Cellular Radio Metrics: RSRP, RSRQ, SINR, and RSSI
A plain-language guide to the four signal numbers shown on a Teltonika router's mobile status page — what each one means in real life, and the rough thresholds for good versus poor.
Part 1: Why ZeroTier Fits Mobile Private Networks
The design case for using ZeroTier to connect RV, marine, and other mobile sites behind changing WAN links, carrier NAT, and intermittent internet access.
Part 2: Self-Hosting a ZeroTier Controller with ZTnet
How a self-hosted ZeroTier controller and ZTnet fit into a private mobile fleet, including controller scope, backups, and access control.
Part 3: Split-Horizon DNS for Mobile ZeroTier Sites
A split-horizon DNS design for mobile private networks, using registered domains, local authoritative answers, and DNSSEC-aware public delegation.
Part 4: Managed Routes and DNS in ZeroTier
How to distribute LAN routes and site DNS settings from the ZeroTier controller so users can reach private mobile-site services without manual network setup.
Part 5: Trusted Certificates for Private ZeroTier Sites
How to use public ACME certificates and DNS-01 validation for private mobile-site names without exposing Home Assistant or router interfaces to the public internet.
