I recently purchased TP-Link AXE5400 Tri-Band WiFi 6E Router (Archer AXE75) to setup a smart home by creating wireless connections to multiple devices (smart plugs, bulbs, Amazon Echos, ect). However, I am still unable to connect to every smart device in my home using the TP-Link AXE5400. Now this could be because it located in the basement where my desktop is setup and there are multiple walls between it and some of the smart devices AND in some cases that includes exterior lights.

So my question is simple, is the TP-Link AXE5400 the best wireless router for this role or is there a better wireless router manufactured by TP-Link better suited for creating a smart home and connecting longer distances (through walls)? Please let me know your thoughts.
