AC4000 MU-MIMO Tri-Band Wi-Fi Router

Boost the speed and efficiency of your home network while protecting users from online threats with the Archer A20 AC4000 MU-MIMO Tri-Band Wi-Fi Router from TP-Link. Equipped with six external antennas and capable of up to 4 Gb/s of total Wi-Fi data throughout, the tri-band Archer A20 comes equipped with a Gigabit Ethernet WAN port and four Gigabit Ethernet LAN ports. Support for link aggregation lets you combine two of the LAN ports for wired data speeds up to 2 Gb/s.

The Archer 20's RangeBoost feature is designed to boost the range of your wireless network, while beamforming support lets the router focus its Wi-Fi signals on nearby devices. Multi-user MIMO support allows the Archer 20 to stream data to multiple devices simultaneously. The router comes with three years of HomeCare service, which offers protection from online threats, enhanced parental controls, and QoS (Quality of Service) features that help to boost network efficiency by prioritizing latency-sensitive traffic.

Faster Wi-Fi

NitroQAM is designed to boost speeds on all Wi-Fi bands by 25%, while Smart Connect and airtime fairness distribute dedicated Wi-Fi streams to each device. With tri-band and MU-MIMO technology, the Archer A20 allows more devices to communicate at the same time, keeping you connected whether you're gaming or online chatting with your friends.

Quad-Core Processor

Archer A20 powers every service, thread, and application running on your network with a 1.8 GHz 64-bit quad-core CPU, which helps to ensure lag-free connections to gaming, streaming and mobile devices. 512MB of RAM and three additional Wi-Fi processors support the router's quad-core CPU and help to keep your network running at optimal speeds by balancing Wi-Fi demand.

Enhanced Wi-Fi Coverage

Beamforming and RangeBoost features help the Archer A20 deliver a stronger Wi-Fi signal with greater range.

Wired Network Performance

Four Gigabit Ethernet LAN ports and a Gigabit Ethernet WAN port help your wired devices reach peak performance for smooth gaming and streaming. You can also use USB 3.0/3.1 Gen 1 and USB 2.0 ports to connect printers, storage devices, and other USB devices to your network. By combining two separate Ethernet ports, link aggregation brings you double the connection speed, up to 2 Gb/s.


TP-Link HomeCare helps to ensure every device on your network remains protected, with a threat database updated live by Trend Micro. Powerful parental controls can limit online time and block inappropriate content according to unique profiles created for each family member, while built-in antivirus features help to protect connected devices from online threats. QoS (Quality of Service) features prioritize devices and applications for faster performance when needed. HomeCare is included for 3 years from date of activation at no additional cost, after which it requires an opt-in subscription at an additional cost. Opting out of this subscription disables certain features.

Works with Alexa and IFTTT

Add new devices to your network, prioritize devices and activities, share the guest Wi-Fi password, and more with Amazon Alexa and your voice. Trigger actions when devices are connecting, disconnecting or being added to your network and set triggers to prioritize a device or an activity with anything that works with IFTTT.

Easy Setup and Management

Set up the Archer A20 in minutes thanks to its intuitive web interface and the powerful Tether app. Tether also lets you manage its network settings from any Android or iOS device, such as guest network and parental controls.
