The TP-Link Deco S4 1-pack is an add-on mesh unit built to extend an existing TP-Link Deco network rather than start one from scratch. Drop it into a home already running Deco hardware and it joins the same mesh, sharing a single network name and password so phones and laptops hand off between units automatically instead of forcing you to reconnect room to room. Paired with one or more Deco units, coverage reaches up to 2,000 square feet, which is enough to push signal into the back bedroom or basement corner that your router never quite reached. Each unit carries two Gigabit Ethernet ports…
