Hi Ping-Ke, We've found that when creating 5G AP on 8821AE, it's not on other devices' wifi list. Here's the steps I used to create an AP: $ nmcli c add type wifi ifname wlp3s0 con-name hello autoconnect no ssid hello $ nmcli c modify hello 802-11-wireless.mode ap ipv4.method shared 802-11-wireless.band a $ nmcli connection up hello If we change "802-11-wireless.band" to "bg", then the AP can be scanned by other devices. Does 8821AE have hardware capability to support 5G AP? Kai-Heng
