How We Work

Flexible engineering support models designed for real-world OpenWrt and embedded networking challenges.

Technical Focus Areas

We work deep in the OpenWrt and embedded networking stack, focusing on problems that affect real deployments.

  • Multi-vendor 4G/5G modem integration (QMI, MBIM, RNDIS & AT command abstraction)
  • OpenWrt system architecture & custom firmware builds
  • CPE platform engineering & board bring-up
  • LuCI-based management UI & real-time cellular diagnostics
  • ISP provisioning workflows, RADIUS & captive portal integration

Short-Term Engineering Support

Hands-on help when your OpenWrt or networking project is blocked, unstable, or behind schedule. We jump in, diagnose fast, and unblock delivery.

  • OpenWrt build & runtime debugging
  • LuCI UI and configuration flow issues
  • Network, Wi-Fi, WAN, and client-management problems
  • Release blockers and production bugs
Discuss Your Issue

Ongoing Technical Partnership

Reliable, recurring engineering support for teams that need continuous development, maintenance, and system hardening — without hiring full-time.

  • Feature development & maintenance
  • UI + backend coordination
  • Release readiness & regression fixing
  • Architecture and code reviews

5G CPE Firmware Platform – Multi-Vendor Modem Integration

Designed and implemented a modular OpenWrt-based 5G CPE firmware platform supporting multiple cellular modem vendors. Built boot-time modem detection, dynamic QMI/MBIM configuration, 5G SA/NSA mode detection, signal normalization, and LuCI-integrated cellular diagnostics.

Validated across multiple modem variants with consistent 500–700 Mbps downlink performance in NSA deployments.

Embedded Gateway Platform Engineering (OEM Engagement)

Customized OpenWrt firmware and board support layers for a networking gateway device. Work included device tree updates, MAC provisioning, Wi-Fi initialization logic, QMI stabilization, and production release hardening.

ISP Network Management Stabilization

Joined an in-progress OpenWrt-based ISP management system to unblock release delays and improve reliability. Focused on client visibility, configuration safety, backend coordination, and production issue resolution.

Product Team Release Recovery

Provided short-term embedded engineering support to resolve WAN and Wi-Fi instability, configuration race conditions, and system observability issues prior to production release.

About GNSOFTLAB

GNSOFTLAB is a small team of senior embedded engineers specializing in OpenWrt-based networking platforms, 4G/5G modem integration, and CPE firmware architecture.

We work directly with OEMs, ISPs, and product teams to design, stabilize, and extend embedded networking systems — from boot-level modem detection and network stack integration to LuCI-based management interfaces and production release hardening.

Our focus is platform-level engineering: reducing vendor lock-in, supporting multi-hardware deployments, and building firmware systems that scale beyond a single device SKU.

We operate lean, engineer-to-engineer, without agency overhead — providing deep technical support where it matters most.
