Will my 2019 iMac support Wi-Fi 7?

iMac (Retina 4K, 21.5-inch, 2019) - Technical Specifications - Apple Support indicates that your Mac has 802.11ac Wi-Fi wireless networking that is IEEE 802.11a/b/g/n compatible.

According to Wikipedia,

• Wi-Fi 5 is IEEE 802.11ac, adopted in 2013.
• Wi-Fi 6 is IEEE 802.11ax, adopted in 2021.
• Wi-Fi 7 is IEEE 802.11be, adopted in 2024.
• Wi-Fi 8 is IEEE 802.11bn, a work in progress.

Your iMac came out when 802.11ac was the latest standard, and thus has WI-Fi 5.

There is no way to upgrade the built-in Wi-Fi.

You might be able to get an external USB Wi-Fi adapter, but you would need to check that it supported both Wi-Fi 7 and your Mac.

It will connect to a Wi-Fi 7 network but can't take advantage of the new features.

Basically we're all just saying no cuz its too old. It will connect but will act like it is a Wi-Fi 5 Network.
