  • I cannot get my EB-U42 to connect to my LAN. It also does not display the QR codes. When pressing the LAN button it either says Screen mirroring error occured, or it says No network to connect.
    If I press the User button on the remote, it says Currently this button cannot be used.
    Some options on the network function are greyed out, e.g. Screen mirroring settings, Display the QR code, Screen mirror info, Net. Info - Wireless LAN

    The machine did work before and there was no problem connecting to the LAN or displaying the QR code. I might have changed a setting.
    The home screen does not display the Projector name, SSID, PIN, IP, etc. Submitted on 10-5-2021 at 15:45
