ESR-9850 300Mbps Wireless N Gigabit Router was designed with range and speed in mind. With expanded bandwidth, multiple users can wirelessly go online, make large file transfers, print to networked printers, and stream multimedia – at the same time.

Gigabit switches are for delivering optimal throughput speed and ample bandwidth for other Ethernet-capable devices such as game consoles, HDTVs, VoIP, phones, Blu-ray players, set top boxes, or DVRs.

With QoS technology, it essentially avoids lags for hardcore gamers while playing online game. The ESR9850 also supports all the standard WPA / WPA2 security features contained in routers today. Multiple guest SSIDs, advanced SPI firewall, Denial of Service (DoS) attack blocking, MAC and URL filtering, etc. further secure your network connections.
