Hello There, You want a professional grade 4G Wi Fi gateway built on your Raspberry Pi 5. I will provide a custom installation script that configures your SIM7600G H module and UPS HAT into a fully manageable router with advanced firewall and monitoring capabilities. 1) Does your cellular provider require a specific APN or username and password to activate the 4G data link? 2) What is your preferred Wi Fi SSID and security password for the initial access point setup? 3) Do you need a specific VLAN configuration for separate guest and private network traffic? We will turn your Raspberry Pi into a powerful and portable internet command center that gives you enterprise level control over your connection. You can stop relying on basic hotspots and start using a system that tracks every byte of data while protecting your hardware from sudden power losses. This setup provides you with the ultimate flexibility to manage your own network rules and visibility, ensuring your mobile office stays online and secure no matter where you set up shop. Best regards, Bharat Joshi

@asimaarbi

I can build this using a Raspberry Pi 5 with OpenWrt or a lightweight Raspberry Pi OS + NetworkManager setup, depending on what level of control you prefer. I’ve previously set up Raspberry Pi 4-based access points and custom router systems (Apache/hostapd, NAT, DHCP, firewall rules), so extending this to a SIM7600G-H 4G gateway on Pi 5 is straightforward for me. I’ll configure automatic modem detection (QMI/PPP), Wi-Fi AP, full routing stack, UPS-safe shutdown, and add bandwidth monitoring with a simple web/CLI interface. I can deliver either a bootable image or a fully automated install script with documentation so you can recreate or modify the setup easily.

@jakubf41

Hi, this is exactly the kind of system I build-reliable, configurable, and closer to a real network appliance than a hobby setup. I’d base this on a hardened Linux stack (either OpenWrt or Raspberry Pi OS with custom services), depending on how much flexibility vs simplicity you want. I’ll handle modem auto-init (QMI preferred for throughput), persistent routing, and a clean AP setup with full control over security and channels. For admin and monitoring, I’ll integrate a lightweight web UI (LuCI or Cockpit-style) with real-time + historical bandwidth stats, plus full SSH access for advanced rules (nftables/QoS/VLANs). Power events from the UPS will trigger safe shutdown via monitored GPIO/I2C signals. I’ve built similar 4G/LTE gateways and multi-interface routers where stability, auto-recovery, and clean configuration mattered—so you won’t get a fragile script, but a system that boots and just works. You’ll receive a ready-to-flash image or reproducible installer, with clear docs and easy extensibility. Let’s make this a solid, plug-and-go gateway.

@ShaunG24

Hi, The primary technical challenge in this project is ensuring that the Raspberry Pi 5 can reliably boot into a router environment while managing the complexities of 4G connectivity with the SIM7600G-H module. This matters because unstable connections or inadequate firewall rules could compromise performance and security. I understand the importance of a clean web interface and SSH access for configuration, as this will facilitate ease of use for advanced administration. Your project requires a well-rounded approach to create a bootable SD-card image or an installer that meets specific network configuration needs. I have extensive experience with Raspberry Pi setups and networking, having built custom router solutions in the past that involved similar hardware and software components. This experience directly relates to your needs, particularly in developing automatic detection mechanisms and user-friendly interfaces. In my previous work, I focused on ensuring reliable hardware communication, specifically with USB modems, and created robust firewall configurations that included VLANs and real-time monitoring. I also implemented safe shutdown protocols, which is essential for projects like yours involving battery power. This has helped ensure uptime and stability, which I can replicate for your gateway project. To tackle this project, I would start with a requirements analysis to ensure all functionalities are captured, followed by building the image with the appropriate network settings and interfaces. I would conduct thorough testing, particularly around the SIM7600G-H detection and battery management features, to mitigate risks of connection drops and data loss. Finally, I would document the process comprehensively to ensure you can manage and extend the setup in the future. What are your specific preferences for the web interface design? How do you envision the real-time bandwidth monitoring feature functioning? Regards, Shaun

⭐⭐⭐⭐⭐ I can deliver a bootable image or one-shot installer that turns your Pi into a dependable 4G gateway + Wi-Fi AP with full admin control. Stack I’ll use (robust + flexible): • Raspberry Pi OS (64-bit, minimal) • ModemManager + libqmi (QMI preferred; PPP fallback) • NetworkManager (profiles, VLANs) • hostapd (AP) + dnsmasq (DHCP) • nftables (NAT/firewall) • Monitoring UI: Netdata (live) + vnStat (history) What you’ll get: • Auto-detect modem → bring up QMI data session at boot • Wi-Fi AP (editable SSID/channel/WPA2/3) • NAT + custom rules (nftables), VLAN-ready bridges • SSH + lightweight web UI (Netdata) • UPS handling: GPIO/I2C daemon to trigger safe shutdown on low battery (for your Waveshare UPS HAT (E)) Milestones: Base image + modem bring-up AP + DHCP/NAT + VLAN scaffolding Monitoring (live + historical) UPS safe-shutdown + README Timeline: 3–4 days You’ll flash, insert SIM, join Wi-Fi, and be online with traffic stats immediately. Quick checks: Carrier/APN? (for QMI profile) Prefer WPA2, WPA3, or mixed? Any VLAN plan (e.g., guest network)? I’ll keep it clean, reproducible, and easy to extend.

@amadorjay

Hello, The primary engineering challenge lies in ensuring seamless integration between the SIM7600G-H module and the Raspberry Pi 5 to enable a stable 4G connection. Additionally, maintaining the integrity of advanced network configurations while allowing for real-time bandwidth monitoring presents a complexity in system architecture. Are there specific security protocols you would like implemented for the Wi-Fi access point? Will the network settings need to support multiple VLANs, and if so, how should they be prioritized? I am ready to dive into the details and help you build a robust gateway.

@mayr81

Hi, I’ve built Linux-based edge routers and modem-backed gateways using Raspberry Pi, Quectel/SIMCom LTE modules, hostapd, nftables, and modem management stacks, so this is very much in my wheelhouse. For your Pi 5, I’d recommend Raspberry Pi OS Lite as the base rather than OpenWrt, because it gives better Pi 5, USB modem, and Waveshare UPS integration while still allowing an OpenWrt-style admin experience through SSH plus a clean web UI. I can deliver either a ready-to-flash image or a documented installer that brings up the SIM7600G-H automatically over QMI first with PPP fallback, starts a configurable Wi-Fi AP, enables NAT/DHCP/VLANs/firewall rules, and exposes live plus historical bandwidth stats via Netdata and vnStat in both UI and CLI. I’d also wire in safe low-battery handling for the UPS HAT, including graceful shutdown thresholds and logging, and keep all routing pieces editable so you can tune nftables, QoS, DHCP scopes, and SSID/security settings without fighting a locked-down appliance. Before I build it, do you want the web admin centered around Cockpit plus router-specific controls, or would you prefer something closer to LuCI in feel? Also, are you planning to use the Pi’s onboard Wi-Fi as the AP long-term, or should I optimize for an external USB adapter for stronger AP stability under load?
