Hello @chenfeng2016 ,

 

88W8997 only has 1 MAC , it can't work at 5G & 2.4G at the same time. 

if you connect it to 5G AP,  it will work on 5G band.

if you connect it to 2.4G AP, it will switch from 5G to 2.4G.

Now, you can try the wpa_supplicant.conf.

----------------------------------

network={
ssid="AP name"
psk="AP PASSWORD"
key_mgmt=WPA-PSK
freq_list=5745 5765 5785 5805 5825 5320 5300 5280 5260 5240 5220 5200 5180 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472
}

-------------------------

STA will choose 5g first. If there is no 5g AP, it will choose 2.4G AP
