I have WLC 2504 which has one 1142 and one 2702 AP connected in local mode. I have one SSID available on both 2.4 & 5 GHz. My issue is connection speed is stuck at 114Mbps on 5Ghz. I am using Windows 10 Lenovo laptop for testing with Intel(R) Wireless-AC 9560 160MHz. I set the band preference to 5Ghz so that laptop prefers 5Ghz band.
This is the view I get in controller for the client.
AP Name: 1142_2 (Ch 157)
Nearest APs: 2702_1(-78 dBm)
Device Type: Microsoft-Workstation
Performance: Signal Strength: -26 dBm Signal Quality: 67 dB Connection Speed: 144 Mbps Channel Width: 20 MHz
Capabilities: 802.11n (5GHz) Spatial Stream: 2
Cisco Compatible: Supported (CCX v 4 )
Connection Score: 100%
I have snapshots of the settings attached. Could someone please guide me what I am missing. I am expecting the speed to be 300 mbps for 1142 5Ghz band.

On a side note, if the same PC connects to 2702 AP it shows 866mbps on 5GHz as connection speed. So there is something special about 1142 configuration. I have one more 1142 and I see the same behavior of link speed capping at 144mbps.
