Picture this: you pull into a rented farmhouse in the Algarve on a Sunday evening, deadline looming Monday morning, and the property’s router is dead. The host is unreachable. The nearest town with a coworking space is 40 minutes away. I’d been carrying the GL.iNet Spitz AX (GL-X3000) for exactly this kind of situation. I slid in an Orange Portugal nano-SIM I’d picked up at the airport, screwed on two of the four external antennas, plugged the device into a USB-C charger, and waited. The status LEDs cycled through amber, then turned solid white. Three minutes after opening the box, my laptop was pulling 220 Mbps down and 48 Mbps up. That moment converted me. Over the following six months I used this router as my primary connectivity device across Portugal, Thailand, and a van trip along the Mediterranean coast. I tested it on four carriers, at elevations from sea level to a Spanish mesa village at 1,100 metres, and in a Bangkok coworking space as a backup to chronically unreliable house wifi. This review covers everything I found: the speeds, the firmware quirks, the honest drawbacks, and the edge cases most write-ups skip. The short version is that the Spitz AX is the best portable 5G router for serious remote workers, with a price tag that matches the ambition.

The Challenge
The Solution
First Impressions
The Spitz AX ships in a no-frills cardboard box with the unit, a short USB-C cable, four detachable SMA antennas, and a quick-start card. No power adapter is included, which feels like a miss at this price point, though the USB-C PD input means most modern laptop chargers or GaN bricks will work. The device itself measures roughly 16 x 11 x 3 cm and weighs around 400 g with antennas attached. That’s about the footprint of a thick paperback, and it fits in the side pocket of a 30-litre pack without drama. Build quality is plastic-heavy but feels solid. The four rubber-footed base sits flat on any desk surface without sliding. Along the top panel you get four SMA antenna ports (two for 5G/LTE, two for Wi-Fi), plus a clear row of status LEDs: power, internet connectivity, 5G/4G signal strength (three bars), Wi-Fi 2.4 GHz, Wi-Fi 5 GHz, and SIM slot indicator. One hardware button on the side cycles through Wi-Fi modes. On the rear: a USB-A 3.0 port, one WAN Ethernet, two LAN Ethernet, and the USB-C power input. The placement of the USB-C port next to the LAN ports is slightly awkward when you stack cables on a desk, but it is a minor gripe.
Key Features for Remote Work
5G Sub-6 Performance
The Spitz AX uses the Qualcomm SDX55 modem, supporting 5G NR Sub-6 GHz bands (no mmWave). In practical terms that means strong indoor penetration and wider geographic coverage at the cost of the theoretical multi-gigabit ceiling of mmWave. Real-world downlink in a well-served urban area landed between 180 and 340 Mbps depending on tower load and band aggregation. Uplink stayed in the 30-80 Mbps range. Latency on a good 5G signal measured 12-22 ms to a nearby server, which is more than adequate for video calls and real-time collaboration tools. The device supports LTE Cat 20 fallback, so in areas without 5G you still get solid 4G performance. One thing to note: the router does not support 5G SA (Standalone) mode, only NSA (Non-Standalone), which relies on an LTE anchor channel. That matters in a small number of markets where carriers have moved aggressively to 5G SA deployments.
Dual-SIM Failover
Two physical nano-SIM slots sit under a panel on the base. You can configure SIM 1 as primary and SIM 2 as failover with an automatic switchover trigger based on signal strength, data quota, or a custom ping-based check. In six months I triggered failover three times for real, not in testing: once when Orange Portugal dropped signal in a tunnel-heavy motorway stretch and a Vodafone SIM picked up seamlessly, and twice during a Thai trip when my local DTAC SIM hit its daily speed cap. Each switchover took under 10 seconds and no active VoIP calls dropped. One common misunderstanding: the Spitz AX does NOT support eSIM natively at the hardware level. You cannot provision an Airalo or Holafly eSIM directly onto the device. You need a physical nano-SIM. Some users get around this by using an eSIM-capable phone in USB tethering mode, but that defeats the purpose somewhat.
WireGuard VPN Built-in
This is where the Spitz AX separates itself from every consumer mobile router on the market. WireGuard is built into the GL.iNet firmware with a point-and-click setup: paste your config file, toggle the switch, done. In testing, WireGuard overhead cost me around 8-12% of raw throughput. On a 220 Mbps connection, that translates to roughly 195-200 Mbps with VPN active, which is imperceptible for day-to-day work. OpenVPN is also supported and works well, though it is noticeably slower at roughly 50-70 Mbps ceiling due to CPU limits. The router can also act as a VPN server, letting you tunnel into your home or office network from anywhere. For anyone working with clients that require access to resources on a specific IP, this is extremely useful without needing a separate VPN appliance.
OpenWRT Firmware
GL.iNet ships a custom interface layered on top of OpenWRT, so you get two tiers of control. The GL.iNet panel covers 90% of what most users need: SIM management, VPN config, Wi-Fi settings, firewall rules, and parental controls. Drop into the OpenWRT LuCI interface and the full power of the platform opens up: custom routing rules, VLAN segmentation, dynamic DNS, traffic shaping, and package installation via opkg. I used it to set up a VLAN that isolates client devices from my work laptop, which is something no hotspot or consumer router handles cleanly. The learning curve is real for anyone who has never touched router firmware before. If you want plug-and-play, this is not your device. If you find network configuration interesting, the depth here is satisfying. Firmware updates from GL.iNet have come roughly every 8-10 weeks throughout my test period, with patch notes that actually describe what changed.
Wi-Fi 6 Coverage
The AX3000 classification means a combined theoretical throughput of 574 Mbps on 2.4 GHz and 2,402 Mbps on 5 GHz under Wi-Fi 6 (802.11ax). In a real apartment or coworking space these numbers come down significantly, but Wi-Fi 6’s OFDMA and BSS Coloring improvements mean the router handles many simultaneous devices much better than older Wi-Fi 5 gear. With six devices connected (two laptops, a tablet, two phones, one smart TV), I saw no perceptible slowdown in 5 GHz throughput. The 2.4 GHz band is useful for IoT devices and anything more than 15 metres from the router. Physical range in an open space is adequate at around 20-25 metres on 5 GHz before signal degrades noticeably. In a concrete Airbnb building, that drops to 10-15 metres through walls, which is normal for any 5 GHz device.
Ethernet Ports for Fallback Cable Internet
One WAN port and two LAN ports give you wired options that most mobile routers omit entirely. The WAN port lets you plug into a hotel or Airbnb’s cable internet when it’s available, while the router still handles VPN, firewall, and Wi-Fi distribution. This is underrated: I used it in a Lisbon Airbnb where the host had a solid fiber connection but only a single Ethernet run. The Spitz AX bridged cable WAN for my laptop, extended Wi-Fi to the rest of the apartment, and kept the cellular SIM warm as a backup. The LAN ports also accept a laptop direct connection for maximum throughput without Wi-Fi overhead. On a cabled connection through the WAN port I measured 940 Mbps down on a gigabit fiber line, close to wire speed.
Power Options (USB-C PD)
The Spitz AX draws power via USB-C PD at 12V/3A (36W spec, though average draw under load measures around 12-18W). Any USB-C PD charger rated at 30W or higher works, including most laptop GaN adapters. In a van setup I powered it from a 12V car socket via a USB-C PD trigger cable with no issues. A 20,000 mAh USB-C power bank (65W PD output) ran the router for approximately 8-10 hours in my tests, enough for a full workday away from shore power. There is no internal battery, which is the right trade-off for keeping the form factor compact. For extended off-grid use, pairing it with a small power station is the practical solution. Power consumption stays low enough that it adds only a minor drain on any reasonably sized battery pack.
Pros and Cons
Pros
- +Dual-SIM failover that actually works: sub-10-second switchover, no dropped calls in six months of testing
- +WireGuard built in with minimal throughput overhead (8-12%), no separate device or subscription needed
- +OpenWRT base gives power users VLAN, custom routing, traffic shaping, and package installation
- +Ethernet WAN port lets you bridge cable internet and use cellular as standby in the same device
- +Wi-Fi 6 handles 6-8 simultaneous devices cleanly with no perceptible degradation on 5 GHz
- +External antenna ports (4x SMA) allow serious signal improvement with aftermarket panels
Cons
- −Price around €400 street price (lower than the old €599 MSRP, but still a premium buy): hard to justify for occasional travelers or anyone who only needs connectivity a few days a month
- −No native eSIM support: Airalo, Holafly, and other eSIM-only providers are not compatible without a workaround involving a secondary phone
- −OpenWRT learning curve: the GL.iNet interface covers the basics, but advanced configuration requires comfort with networking concepts that casual users may find frustrating
- −5G SA (Standalone) not supported: only 5G NSA, which matters in markets like South Korea or some US carriers moving to SA-only deployments

Verdict
The GL.iNet Spitz AX is the right tool for a specific type of traveler: the person who works full-time remotely, moves across multiple countries per year, and treats reliable internet as a non-negotiable cost of doing business. If that describes you, the price is easy to rationalize against a single lost workday or a missed client call over unreliable hotel Wi-Fi. Full-time nomads, vanlifers with a solar or battery setup, and home-office workers who need a serious cellular backup will all find this device earns its place. If you travel a few times a year and just need something better than your phone hotspot, skip it. The GL.iNet Beryl AX (GL-MT3000) costs under €100, runs the same OpenWRT firmware, and handles Wi-Fi 6 perfectly without a cellular modem. If 5G speeds matter but you want a more consumer-friendly device, the Netgear Nighthawk M6 is faster to set up, though it lacks dual-SIM, VPN integration, and Ethernet WAN. For anyone who has read this far and recognizes their own use case in it: the Spitz AX is the device.
