PRODUCT DESCRIPTION

    D-Link G403C 4G LTE N300 Wi-Fi Router - 3 Year Warranty

    D-Link G403C 4G LTE N300 Wi‑Fi Router

    The D-Link G403C 4G LTE N300 Wi-Fi Router is a simple and reliable plug-and-play solution for internet access using a SIM card. It’s designed for homes, small offices, pop-up setups, or backup connectivity when fibre goes down. Just insert a nano SIM and you’ll get instant WiFi without needing fixed broadband.

    4G LTE Internet Anytime, Anywhere

    The router supports 4G LTE Cat 4 speeds up to 150 Mbps download and 50 Mbps upload, making it suitable for daily tasks like browsing, video calls, and streaming. It works well in areas without wired internet or as a backup line for business continuity.

    N300 WiFi for Everyday Usage

    With WiFi speeds up to 300 Mbps on 2.4GHz, the G403C handles typical workloads like emails, web browsing, and light streaming smoothly. It’s not meant for heavy gaming or high-bandwidth users, but solid for general office or home use.

    Connect Up to 32 Devices

    You can connect up to 32 devices simultaneously, making it suitable for small teams, families, or shared environments. Phones, laptops, tablets, and smart devices can all connect without needing multiple networks.

    WAN Failover for Backup Internet

    One key feature is WAN failover, which automatically switches between 4G and wired broadband if one connection fails. This ensures uninterrupted connectivity—useful for SMEs or critical operations.

    Strong Signal with External Antennas

    The router comes with 4 external antennas (LTE + WiFi, 5dBi) to improve signal strength and coverage. This helps maintain stable connections even in areas with weaker mobile signal.
