Getting to know the Linksys Smart Wi-Fi Modem Router, XAC1900

What is the Linksys Smart Wi-Fi Modem Router, XAC1900?
 
The Linksys Smart Wi-Fi Modem Router, XAC1900 is a simultaneous dual-band 3x3 Gigabit router with two (2) USB ports and supports a maximum of 600 Mbps on the 2.4 GHz band and up to 1300 Mbps on the 5 GHz band.
 
The Linksys Smart Wi-Fi Modem Router, XAC1900 comes with three (3) external antennas for better coverage and range.  This is ideal for media-centric applications such as streaming video, gaming, and Voice over Internet Phone (VoIP). 
 
The Linksys Smart Wi-Fi Modem Router, XAC1900 can create three (3) simultaneous yet separate wireless networks:
  • The 2.4 GHz Network caters to devices in your network that are 802.11n (N-only) and 802.11g (G-only) or a combination of both using Mixed mode.  The Linksys Smart Wi-Fi Modem Router, XAC1900 wireless network settings include the Mixed mode which allows backward compatibility with Wireless-B/G/N devices. 
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 Mixed, N-only, and AC-only.  The Mixed mode will still allow backward compatibility for 802.11a devices. 
QUICK TIP:  Connecting a device with an 802.11ac wireless adapter on the 5 GHz network that is set to AC-only will enable you to achieve up to 1300 Mbps speed.  However, by setting your network to AC-only, all other Wireless-N/G/B devices will not be able to connect.
  • The Guest Access is an additional wireless network feature that allows 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.
