Getting to know the Linksys WRT1900AC

What is the Linksys WRT1900AC?

The Linksys WRT1900AC is a simultaneous dual-band 4x4 Gigabit router with two (2) USB ports (1 x USB 2.0/eSATA combo port and 1 x USB 3.0 port). It supports a maximum of 600 Mbps on the 2.4 GHz band and up to 1.3 Gbps on the 5 GHz band. This router also comes with four (4) hi-performance external antennas for enhanced dual-band communication, maximum signal strength, better coverage, and range.

The Linksys WRT1900AC can accommodate all your wired and wireless connections and is ideal for media-centric applications such as streaming video, gaming, and Voice over Internet Phone (VoIP).

The Linksys WRT1900AC can create four (4) simultaneous yet separate wireless networks:

The 2.4 GHz Network caters to devices in your network that are 802.11b, 802.11g and 802.11n.

QUICK TIP: The maximum speed that your devices can achieve with an 802.11n adapter on the 2.4 GHz band is up to 600 Mbps.

The 5 GHz Network will only be able to cater to devices in your network that are 802.11a, 802.11n and 802.11ac. The Mixed mode will still allow backward compatibility for 802.11a devices.
Two (2) Guest networks both for 2.4 GHz and 5 GHz respectively. These additional wireless networks allow your visitors at home to access the Internet but not your local network (i.e., shared storage devices, printer access).

For your connected home, you may use the 2.4 GHz network to connect your wireless devices to surf the Internet and email, share files and print. The 5 GHz network is best for heavy applications including Voice over IP (VoIP) calls, online gaming, and streaming high-definition videos. To know more about the connected home, click here.

Linksys WRT1900AC features

The Linksys WRT1900AC has built-in USB 3.0 and Combo USB 2.0/eSATA (External Serial Advanced Technology Attachment) ports that can easily add Gigabytes of storage space to your network by connecting an eSATA drive or USB flash disk.
