- Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
- Do not attempt to disassemble or repair the device yourself. This may void the warranty.
7. Troubleshooting
7.1 USB Devices Not Recognized
- Ensure the atolla hub is securely connected to a USB 3.0 port on your computer.
- Check if the individual power switch for the specific USB port on the hub is turned ON (blue LED should be lit).
- Try connecting the USB device directly to your computer to rule out issues with the device itself.
- Restart your computer.
7.2 No Network Connection
- Verify that the Ethernet cable is securely connected to both the hub and your network source (router/modem/wall outlet).
- Check the yellow and green LED indicators on the LAN port of the hub. If they are not lit or blinking, there might be a connection issue.
- Ensure your network source (router/modem) is functioning correctly.
- Try a different Ethernet cable.
- Check your computer's network settings to ensure the wired connection is enabled and configured correctly.
7.3 Slow Data Transfer Speed
- Ensure the hub is connected to a USB 3.0 port on your computer. Connecting to a USB 2.0 port will result in slower speeds.
- Verify that the connected USB device also supports USB 3.0 speeds.
- Avoid connecting too many high-bandwidth devices simultaneously to the hub.
