Hi

The range extender can enhance the network coverage of your router using Wi-Fi. If you have thick walls in your home, it is advisable to consider using an Ethernet Cable to connect the extender to the router, specifically by setting the extender to access point mode.

Given that your router is a dual-band Wi-Fi 6 router, it may be beneficial to explore an extender from the provided link:

One option to consider is the RE705X model.

However, it's important to note that we may not be aware of all the advanced features of your router. Therefore, we recommend reaching out to router support for clarification on any specific advanced functionalities.
