Low wlan speed in windows but high plan speed in Mac with 3802i + 2504

Hi everyone,

I faced a problem after setting my network,

 

My network is:

two 3802i FlexConnect 160MHz

one 2504 controller and in the wlan, FlexConnect, local switching and local auth are enabled

one Synology 918+ NAS with 4*6TB + 2*256GB SSD

one layer-2 switch with Gigabyte ports

all devices are connected via 1G ethernet cables

one MacBook Pro 15 2017

one Laptop with Intel AX200 160MHZ 

one Desktop with Intel AX200 160MHZ

one Desktop with Qualcomm QCNFA364A 2x2 

windows are windows 10 64bit 1903

 

WLC is configured basically according to:

https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-6/b_Cisco_Wireless_LAN_Controller_Configuration_Best_Practices.html

5G ssid is configured to a only

2.4G ssid is configured to b/g only

 

My large data such as video files are stored in my NAS,

1. when using ethernet cable connect switch and computer, the connection speed shows 1G coping large files from NAS to computer can be around 100m/s  <- this is good

2. when using 5G wifi connect MacBook 15 2017, the connection speed shows 1.3G, coping large files from NAS to macbook can be around 70m/s <- this is good

3. but using windows computer or laptop, connect them with 5G wifi, the connection speed shows 1.7G with AX200, 866 with Qualcomm QCNFA364A 2x2, the speeds of coping large files form NAS to windows are similar, only 5m/s -10m/s <- it is not good

 

When deploy only one thin 3702i with out 2504 in my network, everything is good, speed can be 50m/s of ax200 and macbook pro 2017, and 30m/s with Qualcomm QCNFA364A 2x2

 

all the test is in the same environment and in my opinion, the problem may be:

1. the wrong configuration of 2504?

2. some wrong with windows? 

 

Any help?

Can you first try with 40 Mhz channel bandwidth?

What firmware version is the wireless NIC running on? 

Ideally, the wireless NIC should be running on 21.30.X.X.

UPDATE:
1. set ap and wlan at local model
2. 2504 four ports link aggregation set
3. 3802i two ports link aggregation set
4. switch: sg500 28p

now speed: 103m/s wireless

next step: server with ssd drivers using two ports in link aggregation under windows 10 to see if speed can over 103m/s
