6. Rješavanje problema
This section addresses common issues you might encounter with your Zbtlink 4G LTE Router.
6.1 Nema internetske veze
- Provjerite SIM karticu: Ensure the SIM card is correctly inserted and has an active data plan. Verify that the SIM card is compatible with AT&T or T-Mobile networks and the router's supported bands.
- Postavke APN-a: Prijavite se u web dashboard (192.168.1.1) and verify that the Access Point Name (APN) settings are correctly configured for your cellular carrier. These settings are often provided by your carrier.
- Snaga signala: Check the 4G signal strength indicators on the router or in the web interface. If the signal is weak, try repositioning the router or adjusting the 4G antennas.
- WAN veza: If using the WAN port for wired internet, ensure the Ethernet cable is securely connected and your primary internet source is active.
6.2 Slab ili nestabilan Wi-Fi signal
- Položaj antene: Adjust the two 2.4G Wi-Fi antennas for optimal signal coverage.
- Položaj usmjerivača: Place the router in a central location, away from obstructions (thick walls, metal objects) and sources of interference (microwaves, cordless phones).
- Smetnje u kanalu: u web dashboard, try changing the Wi-Fi channel to a less congested one.
6.3 Router Not Responding / Freezing
- Ciklus snage: Disconnect the power adapter, wait 10 seconds, and then reconnect it.
- Hardware Watchdog: The built-in hardware watchdog should automatically reboot the router if it freezes. If this does not occur, a manual power cycle is necessary.
6.4 Resetiranje usmjerivača
- Vraćanje na tvorničke postavke: To restore the router to its factory default settings, locate the ODMOR button (often recessed) on the router. With the router powered on, use a paperclip or a thin object to press and hold the ODMOR button for approximately 10 seconds until the LED indicators flash. Release the button, and the router will reboot with default settings.
- Firmware Rescue Mode: If the router encounters a firmware issue, you can enter rescue mode by long-pressing the ODMOR button while powering on the device. This allows for flashing new firmware.
