Question about AR750S's WiFi chipset

On Luci - Wireless Overview page the radio0 is showing Qualcomm Atheros QCA9887 802.11nac but the radio1 is showing Generic 802.11bgn.

  1. Aren’t both signals the 5GHz and 2.4Ghz using chipset from Qualcomn?
  2. What chipset is used for the 2.4GHz signal?

Thank you.

The 2.4GHz radio1 is part of the main QCA9563 chipset
