Ozark-Connect/NetworkOptimizer v1.19.0 on GitHub

Cable modem and fiber ONT monitoring - track your access network equipment's signal quality, power levels, and error rates over time.

What's New

Cable Modem Monitoring - Poll DOCSIS modems for downstream/upstream power, SNR, and FEC error rates. Supports Netgear CM (CM600, CM1000, CM1200, etc.) and ARRIS Surfboard (SB8200, SB6183) via HTTP scraping.
ONT Device Monitoring - Poll fiber ONTs for RX/TX power, temperature, voltage, and bias current. Supports AT&T residential gateways (BGW320, BGW210) and Realtek-based GPON sticks (ODI DFP-34X-2C2, V-SOL V2801F, T&W TWCGPON657, and other RTL960x modules).
Dashboard Panels - New Cable Modem Stats card and unified ONT Stats card that handles both SFP-based and device-polled ONTs with navigation between them.

CM Stats

New CM Stats tab on the Monitoring page with DS Power, DS SNR, US Power, and FEC Errors charts
FEC error chart shows both correctable and uncorrectable error deltas per interval
Settings section with provider selection, test connection, and polling interval

ONT Stats

New ONT Stats tab on the Monitoring page with RX/TX Power and Temperature charts
Unified dashboard panel shows SFP-based ONTs or device-polled ONTs (or both) with prev/next navigation
Empty state provides clear paths for SFP monitoring vs standalone ONT configuration
Settings section with AT&T Gateway, Realtek ONT Stick, and Generic HTTP ONT providers

Fixes

LanFlowMap startup resilience - Per-device InfluxDB query timeout on startup prevents cascade crashes when InfluxDB is slow after a restart.
Proxmox arm64 install - Skip AppArmor LXC config on hosts without AppArmor support, fixing installation on arm64 Proxmox (e.g., Raspberry Pi 5).

Installation

Windows: Download the MSI installer below

Docker:

docker compose pull && docker compose up -d

macOS (native, recommended for accurate speed tests vs Docker Desktop):

git clone https://github.com/Ozark-Connect/NetworkOptimizer.git && cd NetworkOptimizer && ./scripts/install-macos-native.sh
# or if you already have it cloned
cd NetworkOptimizer && git pull && ./scripts/install-macos-native.sh

Proxmox:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/Ozark-Connect/NetworkOptimizer/main/scripts/proxmox/install.sh)"

For other platforms (Synology, QNAP, Unraid, native Linux), see the Deployment Guide.
