It prints no per-band streams or channel widths. The only split that gives 4 streams in total is 2 streams on each band: 574 Mbps is 2 streams at 40 MHz on 2.4 GHz (4 streams would need a 20 MHz channel and leave none for 5 GHz) and 1201 Mbps is 2 streams at 80 MHz on 5 GHz (1 stream at 160 MHz would make the total 3). Expert Reviews confirms 2x2 MIMO and no 160 MHz support on the 5 GHz radio. No band is a dedicated backhaul: the page lists one Dual-Band system and Tom's Guide says there is no dedicated backhaul channel.2Maker spec sheet (PDF)tp-link.com/us/document/110981Read 23 October 2026Deco X20_V5_Datasheet, Wireless: Signal Rate 574 Mbps on 2.4 GHz, 1201 Mbps on 5 GHz.

The footnote says the 160 MHz bandwidth may be unavailable in the 5 GHz band in some regions.

Band steering over only some of the bands, such as 2.4 and 5 GHz on a tri-band router, counts. AFC is Automated Frequency Coordination, which allows standard power on 6 GHz.

Source9Measurementtomsguide.com/reviews/tp-link-deco-x20Read 23 October 2026Tom's Guide (Brian Nadel, review last updated 14 February 2024, tested in 2021 on the original hardware) used a three-pack in a 100-year-old 3,500 sq. ft. home, Keysight (Ixia) IxChariot set to a busy network and a test notebook as the client. The client model, firmware and band are not named. The review's spec box labels the 15 ft figure as peak performance. Direct rows: 15 ft (4.572 m) 522.1 Mbps, 50 ft (15.24 m) 255.4 Mbps, 75 ft (22.86 m) 112.7 Mbps and 90 ft (27.432 m) 51.1 Mbps. Satellite rows come from the older method: a satellite a floor above the router with the receiving system '50-feet farther away' gave 294.5 Mbps, a satellite 40 ft from the router with the test station 'another 50-feet away' on the same floor gave 65.5 Mbps, and a second satellite downstairs with a system 40 ft away gave 150.5 Mbps. The distances are read as the distance from the satellite to the client. The review also gives 556.5 Mbps through a wall 20 ft from the router and 320.5 Mbps with the client a floor above. Those are not stored, because the through-wall field is defined at 25 ft.
