Its compact form factor fits well in homes or small offices, and its external 5 dBi antennas add functional visual cues that this is a device meant for strong wireless signal distribution.

The hardware setup includes:

• 4 × LAN ports for wired devices

• 1 × WAN port for traditional broadband

• SIM card slot for 4G LTE network access

• External LTE & Wi-Fi antennas for enhanced signal range

These physical elements provide an excellent foundation for a versatile internet hub.

Performance: LTE Cat 4 + Dual-Access Connectivity

The D-Link G403 N300 4G Smart Router (G403/B3GG4IN) supports LTE Cat 4, capable of delivering up to 150 Mbps download and 50 Mbps upload—suitable for HD streaming, video calls, browsing, and general office work.

For those in 3G-only areas, it also supports HSPA+ fallback on Bands 1 and 8. Its compatibility across FDD LTE Bands 1/3/7/8/20/28 and TDD LTE Bands 38/40/41 ensures that it works with most mobile networks in Africa, Europe, and Asia.

It also features failover support: if your primary WAN (fiber/DSL) connection fails, the router automatically switches to 4G LTE, keeping you online without intervention.
