7。 トラブルシューティング

Issue: USB devices are not recognized.

• Ensure the hub's USB-C connector is fully inserted into your computer's USB-C port.
• Try connecting the USB device directly to your computer to verify its functionality.
• ハブの別のポートで USB デバイスをテストします。
• コンピュータを再起動します。
• Check your computer's Device Manager (Windows) or System Information (macOS) to see if the hub or connected devices are listed.

Issue: No network connection via Ethernet.

• Verify that the Ethernet cable is securely connected to both the hub and your router/modem/switch.
• Check the LED indicators on the Ethernet port for link and activity. If no lights, try a different Ethernet cable.
• Ensure your computer's network settings are configured for DHCP (automatic IP address assignment) or the correct static IP.
• Try connecting your computer directly to the Ethernet source to confirm the network source is active.
• Update or reinstall the Ethernet driver if necessary (check j5create support web地点）。

問題: データ転送速度が遅い。

• Ensure you are using USB 3.0/3.1/3.2 compatible devices and cables to achieve 5Gbps speeds. USB 2.0 devices will operate at their native 480Mbps speed.
• Confirm your computer's USB-C port supports USB 3.0/3.1/3.2 data transfer rates.
• For Ethernet, ensure your network infrastructure (router, cables) supports Gigabit Ethernet (1000Mbps).
