iPhone 13/14/15 with IOS version 17+ having less wireless throughput (11ax mode - getting around ~650Mbps)

Dear Team,

We have observed less wireless throughput on iPhones with the latest iOS version. We did some debugging and identified that the iPhones are not responding to the NDPA packet sent by the AP which is used for beamforming.

However, iPhones with versions prior to iOS 14 and Android phones do respond to NDPA packets and achieves higher throughput than iPhones with the latest iOS version.FYR, we have mentioned the throughput numbers taken in iPhone and Android.

We kindly request a high-priority investigation into this issue.

Please let us know if you need any additional information to check this issue. Thanks in advance.
