  • removed the fan (Quieter environment )
  • dropped price to $229 to make it a better overall Value
  • Don’t forget it’s also one of the most open routers on the market – and includes the recent Chaos Calmer firmware via OpenWrt.


Along with these changes, the WRT1900ACS continues to offer some of the most popular features that have been in Linksys routers for several years:

  • Smart Wi-Fi – a set up and management tool for remote access

    • Time controls
    • Remote Product turn off and on
  • Remote access to trouble shoot other networks like your parents or friends
  • Open VPN
  • DNLA server
  • Network Map so you can see all the devices that are on your network – and then provide access
  • Guest Access – Provides a separate network for all your guests so they are not on your home network.  This is great for AirBnB use or for the upcoming holiday with friends/families coming over

*The standard transmission rates – 1.3 Gbps (for 5 GHz), 600 Mbps (for 2.4 GHz) – are the physical data rates. Actual data throughput will be lower and may depend on the mix of wireless products used and external factors. The maximum performance for wireless is derived from IEEE Standard 802.11 specifications. Actual performance can vary, and might result in lower wireless network capacity, data throughput rate, range and coverage. Performance depends on many factors, conditions and variables, including distance from the access point, volume of network traffic, environment building materials and construction, operating system used, mix of wireless products used, interference and other adverse conditions. To achieve maximum performance, routers must be paired with coordinating adapters/and or computers in both the 2.4 and 5.0 GHz band such that the maximum performance can be maximized for each GHz band.
