Whether or not you need an AX (Wi-Fi 6) router depends on your specific needs and circumstances.
If you have a lot of Wi-Fi devices in your home, such as smart home devices, laptops, smartphones, gaming consoles, and streaming devices, and they are all competing for bandwidth, then upgrading to an AX router may help alleviate congestion and provide faster speeds.
Similarly, if you regularly stream 4K or 8K videos, play online games, or download large files, an AX router may provide better performance and a more stable connection.
However, if you only have a few devices and don’t have high-bandwidth requirements, then an older Wi-Fi standard, such as 802.11ac (Wi-Fi 5), may suffice.
Ultimately, the decision to upgrade to an AX router depends on your specific needs and budget.
