"While I’m only getting 18-22MBit (TCP, AP>Client) with the XD3200, the UAP-AC-LITE is stable at 38-45MBit, with the ‘stock’ XD3200 QSDK firmware and proprietary atheros driver I’m getting stable 39-41MBit.

Client readings (AP SNR):
XD3200: -53 dBm
XD3200 QSDK: -41dBm
UAP-AC-LITE: -37dBm

AP readings (Client SNR):
XD3200: -48 dBm / -95 dBm (SNR 47)
XD3200 QSDK: -34 dBm / -95 dBm (SNR 61)
UAP-AC-LITE: -37 dBm / -95 dBm (SNR 58)"
