📡 Why the projector may lose Wi-Fi connection

When radio traffic is high (especially in the 2.4GHz band), projectors may lose Wi-Fi connectivity or stop responding to commands. This is due to the fact that:

  • The 2.4 GHz band is often congested: not only Wi-Fi, but also Bluetooth, microwave ovens, cameras, remotes, alarms, your neighbors, etc. operate in it.

  • If there are many wireless devices running in the same room, the wi-fi modules in the projector may not be able to handle the flood of interference and may lose connection

✅ What to do to restore and stabilize Wi-Fi on projectors

  1. Change the Wi-Fi channel on your router. You may be able to find a freer one

    1. Go to the router settings

    2. Find the Wi-Fi / Wireless → Channel section.

    3. If it is currently set to "Auto" or "6", try manually setting it:

      1. Channel 1 or 11 for the 2.4GHz band

    4. Save the settings and restart the router

  2. Disable unnecessary wireless devices

    1. Temporarily turn off everything that uses Wi-Fi in the room: smartphones, tablets, cameras, TVs, scanners, etc.

    2. This is especially important for devices that are connected but inactive - they also create a load on the airwaves

  3. If possible, connect other devices via cable

    1. The fewer devices on Wi-Fi - the more stable the signal will be for those who are left behind

    2. If you can - switch computers, machines, printers, etc. to Ethernet (LAN)

  4. Check the distance between the room and the projector

    1. Optimum distance is between 2 and 5 meters

    2. Avoid installation near metal, machine tools

  5. Restart the projector (turn off the power completely for 10 seconds)

    1. Sometimes the Wi-Fi module in the projector cannot reconnect after disconnecting from wi-fi, and only a complete power off helps.
