Manufacturer description

The TP-Link Archer A20 is a tri-band AC4000 router built for households where a dozen devices all want bandwidth at once. TP-Link splits traffic across one 2.4GHz and two 5GHz bands, so your 4K streams and game sessions stop competing with phones and smart speakers on a single crowded channel. Driving it is a 1.8GHz quad-core 64-bit processor, which keeps multiple simultaneous requests moving and cuts page-load lag when the network is busy. MU-MIMO serves several clients at the same time instead of round-robin, and Beamforming plus RangeBoost push the signal further into back rooms and upper…

Frequently Asked Questions

Is the Archer A20 a Wi-Fi 6 router?

No. The Archer A20 is an AC4000 tri-band router, which is Wi-Fi 5 (802.11ac). It uses MU-MIMO and Beamforming rather than Wi-Fi 6 features like OFDMA.

What does AC4000 tri band actually mean for my speeds?

AC4000 is the combined theoretical maximum across one 2.4GHz band and two 5GHz bands. No single device hits 4000Mbps; the benefit is that devices spread across three bands instead of crowding one.

How well does it handle 4K streaming and online gaming?

TP-Link positions the A20 for 4K video, streaming, and gaming, pairing tri-band capacity with a 1.8GHz quad-core 64-bit processor to keep multiple simultaneous requests moving.

Does it work with Mac and Linux, or only Windows?

It is OS-independent. TP-Link lists support up to Windows 10, macOS 10.12, and Linux, so setup works from any of the three.

What warranty and support come with it?

TP-Link includes a 2-year warranty plus 24/7 technical support. Check the product listing for current terms in your region.
