    Ultra-fast mobile internet and ultra-fast Wi-Fi — in one!

    Simply pop in a 4G LTE SIM card to the 4G-AC55U LTE router, and the built-in modem connects wirelessly to the internet via super-fast mobile broadband. You can enjoy up to 150Mbps downloads and 50Mbps uploads, with no worries about USB dongle compatibility. It can even connect to a cable modem if you just want to use a 4G LTE connection as a backup internet connection! With its 4X wider Wi-Fi coverage and concurrent 1167Mbps Wi-Fi speed, you can share the internet connection all around your home or office — perfect for locations where 4G LTE speeds are faster than conventional ADSL or cable broadband. Convenient and cable-free, 4G-AC55U will give you smoothly-streaming HD videos and fast file-sharing.

    Blazingly-fast wireless performance

    4G mobile broadband technology means you will enjoy 5X faster downloads and uploads than 3G HSPA+1. The latest 802.11ac 2-transmit, 2-receive (2X2) antenna design, provides up to 6X faster wireless speeds for brilliantly-fast HD video streaming, file transfers and more!

    4G LTE signal strength indicator for easy installation

    4G-AC55U makes it easy to find the best position for your router — simply use the signal strength indicator button to find the location with the strongest 4G LTE signal!

    Detachable and upgradeable 4G LTE antennas

    External mobile broadband antennas perform better than internal antennas. Indoors, the best 4G LTE reception is usually found near a window, but if this isn’t practical you can easily add an antenna extension cable thanks to the detachable antennas with their standard SMA jack connectors.

    4G LTE and Gigabit Ethernet dual-WAN for interruption-free connections

    In addition to its 4G LTE capability, 4G-AC55U has a dedicated Gigabit Ethernet WAN port that can be used as a backup wired internet connection that is activated when the 4G LTE connection fails (failover), and automatically switches back when service is restored (failback). This gives superb flexibility for business or home use — you need never be without an internet connection.

    Advanced multi-layer security

    With 4G-AC55U your home network is protected by a multi-layer security system.

    1. MAC filter: Allows you to block one or more devices based on their MAC addresses.
    2. Access control: Control the level of network access granted to any network device, for example blocking certain ports or internet services.
    3. Keyword filter: Block access to undesirable websites based on keywords and apply these restrictions to specific network devices4
    4. Advanced firewall: Firewall with Stateful Packet Inspection (SPI) protects against common web-based attacks and threats.
