Comtrend WR-6891u N300 Gigabit Ethernet WiFi Router
The Comtrend WR-6891u combines a Gigabit Ethernet WAN connection, four Gigabit LAN ports, and a 2.4 GHz WiFi access point. Designed for residential and business broadband deployments, it connects to an external access device through Ethernet.
Its 802.11n radio supports 2T2R MIMO and wireless PHY rates up to 300 Mbps. TR-069 support allows service providers to configure, troubleshoot, and update the gateway through an Auto Configuration Server.
Key Features
- N300 WiFi on the 2.4 GHz band.
- One Gigabit RJ-45 WAN port and four Gigabit RJ-45 LAN ports.
- One USB 2.0 host interface.
- Backward compatibility with 802.11b/g wireless clients.
- VLAN, QoS, routing, and multicast functions.
- TR-069 remote management.
Wireless Performance
Support for 20 MHz and 40 MHz channels, WMM, and multiple SSIDs provides configuration options for a 2.4 GHz network. The advertised 300 Mbps is a maximum wireless PHY rate; actual throughput is lower and depends on conditions.
Ethernet Connectivity
Connect the WAN port to an appropriately configured modem or ONT Ethernet handoff. Four LAN ports accommodate wired devices. Fiber service requires an external ONT; the router does not terminate an optical fiber connection.
Network Management
Web administration and TR-069 support local configuration and provider management. Available functions depend on the installed firmware and service configuration.
Ideal Applications
- Ethernet handoff connections for FTTH service.
- Residential networks combining wired devices and 2.4 GHz WiFi.
- Provider-managed customer-premises installations.
Compatible Products
The WR-6891u supports the following interface-based connections:
- External broadband modems and ONTs providing an Ethernet handoff, subject to ISP authentication and service requirements.
- 10/100/1000BASE-T Ethernet clients and switches using suitable cabling.
- 2.4 GHz 802.11b/g/n wireless clients using a supported security configuration.
Important: This is an Ethernet WAN router, not an integrated DSL modem or GPON ONT. Confirm ISP provisioning requirements before purchase. Do not assume USB modem support, PoE support, or compatibility with a particular power adapter.
