      What kind of Wi-Fi network do I need for my MacBook?

      Wi-Fi networks use several different standards. As of this writing, the latest standard that MacBook models support is 802.11ax, which provides very fast data rates. Your MacBook can also use older Wi-Fi standards, such as 802.11a, 802.11b, 802.11g, and 802.11n, so you can use most Wi-Fi networks. If your wireless router is several years old, look into upgrading to a newer model, as it may provide a substantial increase in speed.
