The maker sells several hardware versions (V1 to V5) under this name. The spec rows on this page match the current V5 datasheet (2 internal antennas), so the product describes the current US hardware. Earlier versions differ, for example the V1 US datasheet lists 4 internal antennas and a 12 V 1.5 A adapter.6Retailer pageamazon.com/dp/B08D67556WRead 23 October 2026Mfr Part Number Deco X20(1-pack).7Retailer pageamazon.com/dp/B08D5X9GWCRead 23 October 2026Mfr Part Number Deco X20(2-pack).8Retailer pageamazon.com/dp/B085Z35GY6Read 23 October 2026Mfr Part Number Deco X20(3-pack).

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 datasheet prints no streams or widths.10Reviewtomsguide.com/reviews/tp-link-deco-x20Read 23 October 2026The review says the Deco X20 is dual-band and has no dedicated second 5 GHz backhaul channel.
