Best for
- Households without fixed broadband — it provides shared Wi-Fi for up to 32 devices using only a 4G LTE SIM card, making it practical where cabling is unavailable.
- Remote or temporary locations — four external antennas and plug-and-play SIM setup mean it can be operational quickly in locations where running Ethernet is not feasible.
- Families wanting usage controls — built-in parental controls, a guest network, and a monthly data limit feature help manage access and spending.
- Users needing a backup connection — the LAN/WAN port allows it to switch to a wired modem source, providing a fallback if 4G coverage is poor.
- Light everyday internet use — supports gaming, streaming, and general browsing across multiple devices simultaneously on its 2.4 GHz network.
Trade-offs
- Users needing a 5 GHz band — it operates only on 2.4 GHz; there is no 5 GHz radio for reduced interference or higher throughput at shorter range.
- Gigabit wired networking — all four Ethernet ports are 10/100 Mbps, capping wired connections at 100 Mbps.
- 5G NR connectivity — the modem is 4G LTE only and does not support 5G New Radio networks.
- PoE-powered deployments — there is no Power over Ethernet support; it requires a dedicated power adapter.
