Head to head
A mesh system is designed to create a coordinated network across multiple nodes; a WiFi extender relays an existing router signal into a weak-signal area. Your home layout and router matter more than a headline speed label.

Extend a router's signal into one weak area
The verdict
The Deco X20 is sold as a whole-home mesh system with multiple units working together.
The RE700X is a Wi-Fi 6 range extender and also offers access point mode.
An extender adds a relay point without replacing the existing router; its result depends on receiving a usable signal where it is installed.

Common questions
Mesh is usually the more suitable approach when you want several nodes to work as one network across a home. An extender can be a simpler fit for a single weak-signal area, provided it can receive a good signal from the router.
It depends on the extender and router features. Some setups can use the same network name, while others may show a separate network; check the device instructions and compatibility before buying.
Many mesh systems can connect to an existing modem or router, but the configuration varies. Check whether the system supports access point mode or whether you need to put the existing router into bridge mode.
Place it between the router and the weak-signal area, where it can still receive a stable signal. Putting it inside the dead zone may leave it with too little signal to relay effectively.
Not necessarily. The advertised WiFi class is a theoretical link capability, and real throughput depends on the router, client device, distance, interference and how the extender connects back to the router.
