Who it fits

Key specs explained

Wi-Fi Speeds: Up to 300Mbps (2.4GHz ONLY)

This router broadcasts Wi-Fi only on the 2.4GHz band, capping speeds at 300Mbps. You get reliable coverage for basic tasks like web browsing and email, but it is not suitable for high-bandwidth activities like 4K streaming or large file transfers. Compare this to modern mesh systems that offer dual-band or Wi-Fi 6 speeds, which provide significantly faster data rates and less congestion in busy homes.

RAM: 128MB

The device includes 128MB of random access memory, which handles active network connections and background processes. This amount of memory is sufficient for a small number of connected devices and basic routing tasks. If you plan to connect many devices or run complex custom scripts on OpenWrt, this may become a bottleneck. Compare this with larger mesh nodes that often feature 256MB or more for smoother multitasking.

Flash Storage: 16MB NOR + 128MB NAND

This storage configuration separates the system software from user data. The 16MB NOR flash holds the core operating system, while the 128MB NAND flash provides space for additional plugins, logs, and custom configurations. This setup supports the open-source nature of the device, allowing you to install various extensions. Compare this with consumer routers that offer limited expandability, as this setup favors technical users who want to customize their network.

Ethernet Ports: 2

The router features two Ethernet ports, allowing you to connect wired devices like computers or gaming consoles directly to the network. This ensures stable, low-latency connections for critical tasks. You can also use one port for WAN and the other for LAN, or daisy-chain devices. Compare this to mesh systems that often include multiple LAN ports per node, offering more flexibility for wiring your home network.

Battery: 5000mAh

A built-in 5000mAh battery allows the router to operate without a constant power source, providing mobility and backup power during outages. This makes it ideal for travel, remote work sites, or emergency preparedness. You can take it anywhere with a power bank or charge it directly. Compare this to standard mesh nodes that require constant wall power, limiting their placement and use cases to fixed indoor locations.

Design and Build Overview

The GL.iNet Puli is built as a portable industrial router. According to the listing, it includes a 5000mAh battery. This internal power source allows you to use the device without a constant wall connection. You can carry it to locations without available power outlets. The compact form factor supports mobile use cases. You can deploy it in vehicles or during travel. The design prioritizes portability over stationary stability.

The device features two Ethernet ports for wired connections. You can connect computers or other network gear directly. A USB 2.0 port is also included. This allows for additional peripheral support. The listing notes reserved antenna SMA mount holes. You can attach external antennas if you need better signal reception. This flexibility helps you adapt the router to different environments. You are not limited to the internal antenna performance.

The finish and layout support its industrial purpose. The unit comes with a power adapter and Ethernet cable. You get a nano-SIM card slot for cellular connectivity. The open-source nature of the hardware means you can modify its functions. You can install custom software or extend its capabilities. This makes it suitable for DIY projects. You have control over how the device operates. The build supports both fixed and mobile network setups.

Setup and Daily Configuration Guide

You begin setup by inserting a nano-SIM card into the dedicated slot. The device uses a Quectel EG25G 4G module to convert that cellular signal into Wi-Fi. You connect to the router’s web interface to configure the connection. The interface supports both manual and automatic dialing. You can also check signal strength and send SMS messages directly from the dashboard. This gives you clear visibility into your network status without needing external tools.

For ongoing management, you can use GoodCloud. This feature lets you monitor real-time statistics and manage client connections remotely. You can also set up VPN servers or clients through the same web UI. The system comes with OpenWrt pre-installed. This open-source platform is unlocked and programmable. You have access to 128MB of RAM and 128MB of NAND flash storage. These specs allow you to extend functions for DIY projects or specific networking needs. You can also use SSH to manage IoT devices remotely.

In daily use, the router acts as a reliable backup. If your Ethernet internet fails, the 4G LTE connection ensures constant data transmission. You get up to 300Mbps on the 2.4GHz band. This speed supports basic browsing and email. The device also supports WPA3 security and IPv6. You can install OpenVPN or WireGuard for enhanced privacy. The unit includes two Ethernet ports and a USB 2.0 port. These ports let you connect wired devices or expand functionality. You manage everything through the web interface or the GoodCloud app. The setup is straightforward if you follow the online documentation. The device is designed for users who need portable, customizable connectivity.

Before You Buy Puli

You should verify that your SIM provider supports the LTE bands used in your region. The Puli works best with standard nano-SIM cards, so check your carrier’s physical card size before purchasing. Because it runs OpenWrt, you may need extra storage or a USB drive for advanced customizations. The 128MB RAM is sufficient for basic routing, but heavy traffic might require a restart. Keep the 5000mAh battery charged if you plan to move it often. This device serves as a mobile backup or temporary hotspot. It does not replace a full mesh system for whole-home coverage. You would use it alongside your main network for remote sites or travel. Ensure your Ethernet cables are long enough if you connect it to a switch. Regular updates to the OpenWrt system will keep security features like WPA3 and VPNs functioning properly. This router fits into your setup as a specialized tool rather than a primary home gateway.

Check before you buy

• Confirm your SIM card is a nano-SIM size.
• Check LTE band compatibility with your local carrier.
• Ensure you have a power source for travel.
• Verify Ethernet cable length for your setup.
• Review OpenWrt requirements for your technical skill level.
