D-Link DWR-M930 Wireless N300 4G LTE Router
The D-Link DWR-M930 Wireless N300 4G LTE Router is a budget-friendly fixed 4G router designed for simple internet sharing using a SIM card. It’s commonly used for small offices, temporary setups, or as a backup internet line when fibre goes down. Unlike portable MiFi devices, this is a plug-in desktop router with stronger connectivity and more ports.
4G LTE Internet with SIM Card Convenience
The router uses a nano SIM card to provide internet access, supporting 4G LTE speeds up to 150 Mbps download and 50 Mbps upload. This allows you to quickly set up internet without relying on fixed broadband, making it ideal for remote sites or temporary offices.
N300 WiFi for Everyday Connectivity
With Wireless N speeds up to 300 Mbps on 2.4GHz, the DWR-M930 supports typical daily usage such as browsing, video streaming, and work applications. It’s suitable for light to moderate usage but not meant for heavy bandwidth tasks like gaming or large file transfers.
Multiple LAN Ports for Wired Devices
One key advantage over portable routers is connectivity. The DWR-M930 includes 3 LAN ports and 1 WAN/LAN port, allowing you to connect desktops, switches, or other wired devices directly. This makes it more suitable for small office environments compared to mobile hotspots.
External Antennas for Better Signal Stability
The router comes with dedicated LTE and WiFi antennas, improving signal reception and coverage. This helps maintain a stable connection even in areas where mobile signal strength is not ideal.
Budget-Friendly Backup or SME Router
This model is positioned as one of the more affordable 4G routers, offering essential features without advanced capabilities. It’s best used as a backup internet line, SME connectivity solution, or temporary deployment, rather than a full replacement for fibre broadband.
