@Bahar9 Hi， May I know how long have you had the Deco E4 and when did this issue start? Did the 5ghz work fine before? Have you tried to hardware reset the Deco and check on the Wi-Fi analyzer again?...

@BrettOnTheNet Hi, Have you tried dynamic IP connection type and enabled the internet VLAN ID to have a look? Thanks and wait for your reply.

@Iconic Hi, thanks for your feedback. Could you please send a video clip about the database updating issue on the Deco X60? By the way, what is the current date on the Trend Micro Security Database?...

@Harold22 Hi, the video is blink and there is only a white page in the middle. Maybe you could try to send it to my email address, which I have provided via private message; Thank you very much.
