MU-MIMO technology serves several devices at once, reducing wait time, increasing Wi-Fi throughput for every device, and making each stream more efficient. As a powerful DSL modem router, the Archer VR2800 supports super fast VDSL or ADSL broadband, as well a variety of other connection types. The LAN/WAN port accepts connections from cable modem or fiber modem, and both of the USB 3. 0 ports support 3G/4G dongle connections for a perfect main or backup internet connection. Beamforming technology locates the connected devices and further improves the Archer VR2800 s range and the signal strength to each mobile device, delivering a more reliable and efficient wireless connection. Separate Wi-Fi bands enable more devices to connect to your network without a drop in performance.
