The TL-R4000+ adopts Intel IXP network processors, main frequency up to 533MHz, multi-CPU distributed architecture, to ensure high performance and high availability. Additionally, the 6-layer PCB, the built-in high-redundancy power module and the 19-inch rack-mountable steel case feature a new architecture that dramatically stretches the performance of the router by enabling stable connections. Scarcely believed, a built-in fiber module expansion slot, shared with WAN, makes direct fiber connection possible.

The TL-R4000+ features two WAN ports, which allows two connections to the Internet at the same time, provides you double-bandwidth access, and gives the ability to enjoy more Internet sources from different ISPs. With fail-over and automatic load balancing, no manual work should ever be required.

The TL-R4000+ provides all the normal settings of a broadband router, it features much more advanced functions, such as Bandwidth Control, Port Mirror, Port VLAN, IEEE 802.1x Authentication, UPnP, DDNS, VPN Pass-through, Firewall and System Log.

The TL-R4000+ provides a friendly configuration interface for easy use. With multi-function, high-reliability, and high-security, it widely meets enterprise, organ, Internet cafe, broadband community, and school networks new and changing requirements.
