Design and Build
The GLiNet GL-XE3000, also marketed as the Puli AX, adopts a utilitarian design that emphasizes function. Its white chassis houses the core hardware and the sizable 6400mAh battery, contributing to a substantial feel. A notable design element is the inclusion of six detachable external antennas, which are crucial for maximizing cellular and Wi-Fi range in field operations. User reviews confirm that while the unit becomes “chunky” once fully assembled with antennas, this is a recognized trade-off for the enhanced performance and coverage it provides. The router includes a wall mount kit, indicating its suitability for semi-permanent installation in temporary offices, retail spaces, or events. The build quality, as inferred from user comments replacing other hotspots, suggests a focus on durability for mobile use.
Performance and Features
Connectivity and Speed
The GL-XE3000 is built around multi-WAN connectivity. Its primary feature is 5G cellular support, certified for use on T-Mobile and AT&T networks in the US and compatible with 4G LTE. The dual-SIM capability with automatic failover allows the router to switch to a secondary carrier if the primary signal weakens, a key feature for maintaining business continuity. It’s important to note the dual-SIM operates in “single standby” mode, and the cellular modem is restricted in certain regions like Russia and Iran. For wired backup or primary connection, it features a Gigabit Ethernet port. Wi-Fi 6 with MU-MIMO support provides theoretical combined speeds up to nearly 3000 Mbps, designed to handle multiple devices in congested environments like conferences or offices.
Power and Portability
The integrated 6400mAh battery is a defining characteristic. Manufacturer claims and user reviews align, suggesting it can deliver up to 8 hours of uninterrupted connectivity, making the router genuinely portable and an effective backup during power outages. Owners have reported it functioning for several hours through a blackout, keeping essential operations online. This feature directly supports its use cases in construction sites, vehicles, and outdoor events where mains power is unreliable.
Software and Security
The router runs a proprietary GL.iNet firmware based on OpenWrt, which is praised for its customizability. It comes with over 5,000 available plugins for advanced network management. On the security front, it has pre-installed OpenVPN and WireGuard clients, supporting over 30 VPN services. The manufacturer lists maximum VPN throughput at 150 Mbps for OpenVPN and 300 Mbps for WireGuard. Additional security features include WPA3 encryption, DNS over TLS/HTTPS, and standard router functionalities like guest networks and parental controls.
Setup, Support and Ownership
User feedback indicates that setup can be straightforward for basic cellular use, with reports of SIM cards being detected immediately and networks coming online within minutes via the web dashboard. However, some users experienced complications, particularly when integrating with specific carrier plans (like AT&T) due to the device having a single IMEI for dual-SIM slots. The admin portal is generally described as easy to use for switching between operation modes like cellular and Wi-Fi repeater. The router supports a physical eSIM card for easier carrier switching, but this card must be purchased separately. GL.iNet provides a 2-year warranty, and the package includes region-specific power adapters (US, EU, UK, AU).

FAQs
Does the GL-XE3000 support true dual-SIM dual-active connectivity?
No. The GLiNet GL-XE3000 features dual-SIM slots but operates in a “single standby” mode. This means it can hold two SIM cards and automatically switch (failover) to the secondary one if the primary connection is lost or weak, but it cannot use both cellular connections simultaneously for load balancing. This is designed for reliability rather than aggregating bandwidth from two carriers.
Can I use this router as a regular Wi-Fi extender or repeater?
Yes. One of its multi-WAN modes is a “Repeater” function. User reviews confirm this works well, even handling captive portals at hotels. This allows the GL-XE3000 to connect to an existing Wi-Fi network and rebroadcast it, leveraging its powerful antennas and Wi-Fi 6 capabilities to extend coverage, all while potentially adding VPN security to the connection.
What is the physical eSIM card, and do I need it?
The physical eSIM card is a separate accessory sold by GL.iNet. It is not required for standard SIM card operation. This card is designed to simplify switching between different carrier profiles digitally, which can be useful for frequent international travelers. You must purchase this card separately if you want this functionality; it does not come included with the router.
Is the GL-XE3000 suitable for connecting many devices at an event?
Its specifications suggest it is well-suited for this. Wi-Fi 6 with MU-MIMO technology is designed to improve performance in high-density environments by communicating with multiple devices simultaneously. Combined with the high bandwidth potential of a 5G cellular connection, it is marketed for enterprise events, conferences, and exhibitions. For extremely dense device environments, understanding the principles behind the best routers for multiple devices is beneficial.
