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:
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?
What firmware version is the wireless NIC running on?
Ideally, the wireless NIC should be running on 21.30.X.X.
