802.11ac is the latest wireless standard offering speeds up to 3X faster than 802.11n. Operating in the 5 GHz spectrum, 802.11ac offers transfer speeds up to 1300 Mbps, ideal for uninterrupted HD video streaming and concurrent internet access.

Dual 5 GHz and 2.4 GHz bands allow simultaneous connection of more devices

The WXR-1900DHP HighPower wireless LAN router supports 802.11ac 1300 Mbps + 802.11n/g/b 450 Mbps high-speed transfers. This capacity for high-speed communications enables full use of the high transfer rates available with fiber optic and other high-speed circuits, making downloads, large file transfers, playback of high-Vision video, and other data transfers over the Internet easier and more enjoyable.

Access your NAS at Gigabit speed. Optimal for 1 Gbps fiber optic services.

All of the WXR-1900DHP's wired LAN ports (4 LAN ports and 1 Internet port) support Gigabit Ethernet (1000BASE-T), allowing Gigabit connections with computers equipped with Gigabit LAN ports and with TeraStation and LinkStation networked hard disk drives (NAS). This intelligently forms high-speed 1300 Mbps wireless LAN and wired LAN networks. This router is also compatible with Jumbo Frames, larger Ethernet data packets used to increase the efficiency of transfers over networks. This enables fuller utilization of Gigabit transmissions. The WXR-1900DHP's effective wired throughput is 939 Mbps with DHCP and 916 Mbps with PPPoE, for trouble-free Internet connections for wired devices as well.

Beamforming for a stress-free environment and greater Wi-Fi stability

The WXR-1900DHP supports beamforming, a technology that determines a client device's position and distance to allow direction of wireless signals with pinpoint accuracy, even in environments containing numerous homes and other reception-blocking obstacles. This concentrates the radio signal only on the necessary terminals, boosting transfer speeds and improving stability.
* Requires client-side support for beamforming.

"Multi Security" Function Allows Use Mix of Different Wireless LAN Encryption Levels

The WXR-1900DHP supports WPA2-PSK (AES), WPA-PSK (AES), WEP, and WPA2-mixed (AES, TKIP) encryption. This allows use of a mix of encryption levels without downgrading any device's encryption level, even when connecting devices compatible only with lower encryption levels.

Changing advanced settings is simple?anytime, anywhere

Renewing the UI administrator screen makes control from smartphones and tablets a snap. Want to make a guest port temporarily available for a visitor? It's simple and easy, all with a single smartphone.

Connecting the wireless LAN router you've already been using is also simple. Just press the WPS button or AOSS button on the other router and the WXR-1900DHP to create a secure relay, with no need to change the router's settings. Use it the same way you always have.
* The relay function allows connection of up to two connections, including the router and the relay.
* Multi Security can also be used when the WXR-1900DHP is set up as a relay by connecting it to a wireless LAN access point.
* Use of the relay function requires a transmission source wireless LAN router that supports WPS or AOSS.
* Use of the relay function requires a transmission source wireless LAN router that supports 802.11na or 802.11ngb.

Connect your wired device wirelessly with wireless LAN client feature

You can connect a wired device to the WXR-1900DHP's wired (Ethernet) port and use the router to function as a wireless LAN client device, which allows you to connect your wired device to your wireless network. If the wired device has a Wake On LAN (WOL) feature, the device can be powered up remotely through the wireless network. If you have a VPN network, you can also turn on the WOL-endabled device from an external location.
With the purchase of two WXR-1900DHPs, you can use one WXR-1900DHP as a router and one as a client and enjoy the high-speed wireless LAN communications that 801.11ac provides.
