Upgrade broadband and telephony infrastructure with the Zyxel DX3301-T0 Dual-Band Wireless AX1800 VDSL2 VoIP IAD Router. Designed to meet modern multi-play demands, this high-performance gateway combines an integrated VDSL2/ADSL2+ modem, gigabit Ethernet routing, Wi-Fi 6 wireless distribution, and dual FXS ports for crystal-clear VoIP telephony. Engineered with Zyxel's field-proven OPAL firmware and MPro Mesh support, the DX3301-T0 delivers dependable, high-speed connectivity tailored for modern small offices and residential deployments.

Ultrafast Wi-Fi 6 Technology for Multi-Streaming Performance

Eliminate network congestion and dead zones. Supporting the latest Wi-Fi 6 standard, the DX3301-T0 delivers combined wireless speeds of up to 1200 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. Powered by uplink MU-MIMO, Orthogonal Frequency Division Multiple Access (OFDMA), and beamforming technologies, the router ensures smooth, lag-free data access across multiple simultaneous wireless clients.

Seamless Whole-Home Coverage with Zyxel MPro Mesh

Scale your wireless coverage effortlessly across larger premises. Fully compliant with EasyMesh standards, Zyxel MPro Mesh solutions provide self-adapting, easy-to-manage whole-home Wi-Fi coverage. Pairing the DX3301-T0 with compatible wireless extenders like the WX3100 establishes a unified mesh network that eliminates dropouts and maintains strong signals in every room.

Integrated VoIP Telephony and Triple-Play Quality of Service

Support mission-critical voice and video applications with confidence. Equipped with two dedicated FXS telephone ports, the router supports comprehensive SIP v2 VoIP protocols, G.168 echo cancellation, and flexible dial plans. Advanced Quality of Service (QoS) policies allow administrators to prioritise VoIP traffic and IPTV data streams, ensuring optimal performance for business communications.

Enterprise-Grade Security and Advanced Remote Management

Protect your network perimeter against digital threats using a robust Stateful Packet Inspection (SPI) firewall, Denial of Service (DoS) attack defence, and MAC address filtering. Designed for streamlined deployment and lower operating overhead, the gateway supports TR-369, TR-069, and TR-181 standard remote management for deep network visibility and automated provisioning.

Advanced Multi-Play Services with Dedicated IPTV Prioritisation

Designed to cater to modern home and small office entertainment demands, the DX3301-T0 supports comprehensive multi-play service delivery. Built-in Internet Group Management Protocol snooping and proxy features, alongside flexible VLAN tagging, ensure that bandwidth-heavy multicast streams such as IPTV are transmitted smoothly without disrupting standard data traffic or voice calls.

Flexible USB 2.0 Integration and Media Sharing

Equipped with an integrated USB 2.0 port, the gateway extends its functionality far beyond standard routing. Users can connect external USB storage devices to establish a local Network Attached Storage node for effortless file sharing across the network. Alternatively, the port supports connection to a compatible 3G mobile broadband USB dongle, providing an instant cellular backup option for uninterrupted connectivity.

Optimised OPAL Firmware and Rapid Provisioning

Built upon Zyxel's field-proven OPAL software development framework, the DX3301-T0 inherits a robust, standardised feature set across devices. This architecture ensures consistent administrative experiences, rapid firmware updates, and seamless integration with existing network management systems, significantly reducing operational overhead for IT administrators.
