TP-Link Archer BE900 vs TP-Link Deco BE77

The TP-Link Deco BE77 takes the overall verdict on a lower price and a stronger owner rating, while both share the same warranty length. The TP-Link Archer BE900 remains the more powerful single router for buyers who want maximum quad-band throughput.

The Archer BE900 is a standalone quad-band router with twelve internal antennas and dual 10G ports in one box, while the Deco BE77 is a tri-band mesh system built to expand across multiple nodes for whole-home coverage.

No. The TP-Link Deco BE77 is tri-band with one 6 GHz radio, while the TP-Link Archer BE900 is quad-band with two separate 5 GHz radios plus a 6 GHz radio.

The TP-Link Deco BE77 includes a built-in speed test in its app. The TP-Link Archer BE900 does not offer one.

Yes. It supports EasyMesh and TP-Link's OneMesh standard, so it can be extended with compatible units, though it is designed to work well as a single standalone router too.

Buy the TP-Link Deco BE77 for better-rated, expandable tri-band Wi-Fi 7 mesh. Buy the TP-Link Archer BE900 if you want a single quad-band router with maximum throughput and dual 10G ports.
