ADSL2+ Wireless Router 4 Ethernet Port | USB Host | 802.11n WiFi


The AR-5381u is an IPv6 compliant, high performance 802.11n, 4-port Ethernet ADSL2+ Router with full routing capabilities to segment and route IP protocol. It features TR-069/098/111 and TR-068 compliance for hassle-free setup and configuration. It is best suited for residential or small office environments that need high speed internet access.


Connect with ADSL2+ OR Ethernet in FTTx

The AR-5381u is an 802.11n (300Mbps) Wireless ADSL2+ router. It has four 10/100 Base-T Ethernet ports, a Wi-Fi Protected Setup (WPS) button and a Wi-Fi switch button, one USB Host port, which can support a 3G USB dongle, and is backward compatible with existing 802.11b (11Mbps) and 11g (54bps) equipment.

The AR-5381u supports up to 16 contiguous virtual connections allowing for multiple simultaneous Internet connections. The AR-5381u is also designed with TR-068 compliant color panel, which eases the installation of the modem and makes it more user-friendly.

Remote Management

The AR-5381 complies with TR-069/TR-098/ and TR-111 standards to ensure interoperability with standards-based Software and Hardware.

Safe & Secure Connections

As the first level of protection, a Stateful Firewall (with DoS protection) and NAT/PAT help to isolate the LAN from external threats. IP and MAC address filtering provide fine-grained access control to or from the network. Advanced security technologies, such as Virtual Private Networks (VPN) with PPTP pass-through, L2TP pass-through and IPSec pass-through ensure secure networking, and WPA/WPA2/802.1x/WEP guarantee rock-solid security for wireless connections.

Quality of Service

Classify, control, and prioritize diverse traffic types, for pristine video, toll-quality voice, and error-free data transmissions.
