Hi, friend.
E5783B-230 is a consumer product.
You could go to the web-based management page and hide or cancel hiding the Wi-Fi SSID:
Click Advanced > Wi-Fi > Wi-Fi Security Settings > Options.
Un-check Hide Wi-Fi to stop hiding the Wi-Fi SSID.
Check Hide Wi-Fi to hide the Wi-Fi SSID (as a result, phones and other devices will not be able to find the SSID and will have to enter it manually).


Hopes can help you!
