These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
TP-Link Deco S4 AC1900 Mesh Wi-Fi System, 3-Pack
A basic whole-home mesh where Wi-Fi 5 and WPA2 are enough
Three AC1900 Wi-Fi 5 units that form one network name, with optional wired backhaul and both router and access-point modes. TP-Link's spec lists WPA and WPA2 only, no WPA3, and names no subscription for the parental controls. The listing and TP-Link disagree on how many Ethernet ports each unit has.
Published specifications
- Maker: Wi-Fi 5 dual-band; 5 GHz 1300 Mbps + 2.4 GHz 600 Mbps, 3x3 MU-MIMO
- Maker: 3x Gigabit WAN/LAN ports per unit; listing says 2 per unit, 6 per 3-pack
- Maker: Wi-Fi encryption WPA-Personal and WPA2-Personal; WPA3 not listed
- Maker: optional Ethernet backhaul; Router and Access Point modes
- Maker: coverage up to 2,100 sq ft for a 1-pack; listing says 5,500 sq ft for three units
- TP-Link warranty page: 2 years for Deco, original purchaser, proof of purchase and serial
Strengths
- Parental controls and QoS are listed with no subscription or paid tier named for this model
- Optional Gigabit Ethernet backhaul, and the system can run as a router or an access point
- Firmware updates arrive over the air through the Deco app
Caveats
- TP-Link's spec lists no WPA3 support for this model
- TP-Link says three Ethernet ports per unit while the listing says two
- Wi-Fi 5 only, so none of the Wi-Fi 6 capacity features are listed

TP-Link Deco XE75 AXE5400 Tri-Band Wi-Fi 6E Mesh System, 3-Pack
Households that want a dedicated 6 GHz link between nodes
Three tri-band Wi-Fi 6E units, each with three auto-sensing Gigabit ports. The 6 GHz radio is used as the backhaul between nodes by default and can be switched to carry 6E client devices instead. WPA3 is listed, wired backhaul is supported, and some HomeShield features need the paid Pro plan.
Published specifications
- Maker: Wi-Fi 6E tri-band; 6 GHz 2402 + 5 GHz 2402 + 2.4 GHz 574 Mbps, 6 streams
- Maker: 3x Gigabit ports per unit, WAN/LAN auto-sensing; optional Ethernet backhaul
- Maker: WPA-Personal, WPA2-Personal and WPA3-Personal encryption
- Maker: guest network on all three bands; Router and Access Point modes
- Maker: operating temperature 0C to 40C; 4.1 x 4.1 x 6.7 in per unit
- TP-Link warranty page: 2 years for Deco, original purchaser, proof of purchase and serial
Strengths
- The 6 GHz band can carry the backhaul, keeping the 5 GHz band free for your devices
- Three Gigabit ports on every unit, any of which can take the internet feed
- WPA3-Personal is on TP-Link's specification, and guest networks exist on all three bands
Caveats
- HomeShield's Pro plan costs extra, per TP-Link's own footnote
- Ethernet ports top out at 1000 Mbps, so wired backhaul cannot match the 6 GHz radio
- Coverage, speed and 200-device figures are claims TP-Link itself footnotes as not guaranteed
