As of my last knowledge update in January 2022, I don’t have specific details about the latest extender models released after that date. However, I can provide you with some general information on what to look for in the latest Wi-Fi extenders as of that time, and you can check the latest models from reputable manufacturers.

When considering Wi-Fi extenders, look for features such as:

1. Wi-Fi Standards: Make sure the extender supports the latest Wi-Fi standards, such as 802.11ac or 802.11ax (Wi-Fi 6), for better performance and compatibility with modern routers.

2. Dual-Band or Tri-Band: Dual-band extenders operate on both 2.4GHz and 5GHz frequencies, while tri-band extenders add an additional 5GHz band. Tri-band models can potentially offer better performance in crowded Wi-Fi environments.

3. Mesh Networking: Some extenders are part of a mesh network, providing seamless connectivity across multiple units. This is particularly useful for larger homes.

4. Beamforming Technology: This technology helps to focus the Wi-Fi signal in the direction of your devices, improving overall signal strength and stability.

5. MU-MIMO (Multi-User, Multiple Input, Multiple Output): MU-MIMO allows the extender to communicate with multiple devices simultaneously, which can improve performance in busy networks.

6. Ease of Setup: Look for models with easy setup procedures and perhaps mobile apps for configuration.

7. Ethernet Ports: Some extenders come with Ethernet ports, allowing you to connect wired devices directly to the extender for a more stable connection.

To find the latest extender models, check the websites of popular manufacturers such as Netgear, TP-Link, Linksys, Asus, and others. Online retailers and customer reviews can also provide insights into the performance and reliability of specific models.

Remember to verify the latest models and reviews as the technology landscape evolves, and new products are released regularly.
