Ray5 MiniS Wi-Fi Connection Failure Troubleshooting

A stable Wi-Fi connection allows the Ray5 MiniS to communicate with engraving software such as LightBurn and LaserGRBL. If the machine cannot connect to your wireless network, you may not be able to control it wirelessly or send engraving jobs.

Most Wi-Fi connection problems are caused by a weak signal, an unsupported network frequency, or incorrect Wi-Fi settings. This guide explains the most common causes and provides simple troubleshooting steps to help you restore the connection.

1. Check the Wi-Fi Signal Strength

A weak Wi-Fi signal is one of the most common reasons for connection failure. Before changing any settings, check whether the Ray5 MiniS can detect your wireless network. In LightBurn or LaserGRBL, enter the following command in the console:

• $wifi/listAPs

The machine will display a list of available Wi-Fi networks. The number shown after SIGNAL indicates the Wi-Fi signal strength. A value closer to 100 means a stronger signal. If the signal is too weak, the Ray5 MiniS may not be able to connect to the network.

Possible causes and solutions

Loose Wi-Fi Antenna

• The Wi-Fi antenna on the mainboard may be loose.
• Remove the front beam cover of the Ray5 MiniS and reconnect the antenna securely.

Damaged Wi-Fi Antenna

• If the antenna is damaged, replace it with a new one.

2. Check the Wi-Fi Frequency

The Ray5 MiniS supports 2.4 GHz Wi-Fi networks only. If your router is using a 5 GHz network, the machine will not be able to detect or connect to it. If your router supports both frequency bands, make sure the Ray5 MiniS is connected to the 2.4 GHz network.

3. Verify the Wi-Fi Name and Password

Incorrect network information is another common cause of connection failure. Carefully check that the Wi-Fi name (SSID) and password are entered correctly. Even a small typing error may prevent the machine from connecting successfully.

Tips for a Stable Wi-Fi Connection

To help maintain a reliable wireless connection:

• Keep the Ray5 MiniS within a strong Wi-Fi signal range.
• Connect the machine to a 2.4 GHz wireless network.
• Check that the Wi-Fi antenna is securely connected.
• Verify the Wi-Fi name and password before reconnecting.

Conclusion

Most Ray5 MiniS Wi-Fi connection problems can be resolved by checking the signal strength, confirming that the network uses 2.4 GHz, and verifying the Wi-Fi name and password.

If the connection issue continues, inspect the Wi-Fi antenna and make sure it is securely connected to the mainboard. Following these simple troubleshooting steps can help restore the wireless connection and allow you to continue using LightBurn or LaserGRBL smoothly.
