    Provide your large home with fast, reliable, and secure wireless internet access using the TP-Link Archer AX21 AX1800 Wireless Dual-Band Gigabit Router. With this 802.11ax dual-band router, you can transfer data wirelessly at up to 1775 Mb/s over the 2.4 GHz and 5 GHz frequencies for smooth 4K video streaming, online games, video chats, and more. Four Gigabit Ethernet ports are available for high-speed wired connections to computers, video game consoles, smart TVs, and other compatible devices. Plug a flash drive into the USB 2.0 port to share files with all connected devices on the network. You can quickly set up your network using the TP-Link Tether app, including managing guest login access and parental controls. Your network is secured with WPA3 encryption alongside SPI Firewall and VPN support.
    
   
  
 
  
   
    
     High-Performance Wi-Fi
     
      
       Featuring four powerful external antennas and 802.11ax support, the Archer AX21 router can transfer up to 1201 Mb/s over the 5 GHz frequency and 574 Mb/s on the 2.5 GHz band for smooth 4K video streaming, online games, and more.
      
      
     
    
   
    
     Extensive Coverage
     
      
       Beamforming technology detects devices and concentrates the wireless signal strength towards them for a stronger connection over a distance and through walls.
      
      
     
    
   
    
     Efficient Wi-Fi
     
      
       MU-MIMO technology allows the router to simultaneously send and receive data from multiple devices while OFDMA separates a single spectrum into multiple units, enabling devices to share one transmission stream for enhanced efficiency. The Airtime Fairness features further improve network efficiency by limiting excessive use from individual devices.
      
      
     
    
   
    
     Flexible Connectivity
     
      
       Four Gigabit Ethernet ports are available for high-speed wired connections to computers, video game consoles, smart TVs, and more. Plugging a flash drive into the router's USB 2.0 port allows you to share files and content with connected devices across the network.
      
      
     
    
   
    
     Easy Configuration
     
      
       Quickly set up and manage your network using either the web interface or the TP-Link Tether app. You can create separate guest network logins for added security and configure parental controls to block inappropriate content or limit how much time children can spend online.
      
      
     
    
   
    
     Network Security
     
      
       Your network is secured with the WPA3 protocol, which offers enhanced protection against brute-force attacks. The Archer AX21 also has integrated SPI Firewall and VPN support.
