Part of the problem is that Apple has capped the performance of Wi-Fi 7 on the 2024 Pro iPhone models by not allowing the devices to take advantage of the 320 MHz channel width which is in line with Wi-Fi 7. Instead, the iPhone 16 Pro and iPhone 16 Pro Max have their channel capped at 160 MHz which reduces the potential Wi-Fi performance for these expensive premium iPhone models by as much as 50%. This is not a guess or a rumor. The 160 MHz channel figure can be seen on the iPhone’s diagnostic tool.

In Europe, Wi-Fi 7 is limited to one 320 MHz band while in the U.S. there are three. But limiting the channel width to 160MHz is what needs to be fixed, if possible. There has been speculation about a possible software update that could eliminate the current cap. On the other hand, it is possible that there is something in the hardware that is causing the channel to be capped at 160 MHz and if that is the case, there might not be anything that can be done.
