8. Feilsøking
| Problem | Mulig årsak | Løsning |
|---|---|---|
| Ingen strøm | Strømadapteren er ikke tilkoblet eller defekt. | Ensure power adapter is securely connected to the device and a working power outlet. Test with another outlet if possible. |
| No Dial Tone on FXS Port | Phone not connected, SIP account not registered, or incorrect configuration. | Check phone connection. Verify SIP account registration status in the web grensesnitt. Review FXS port configuration. |
| Cannot Make/Receive Calls via FXO | PSTN line not connected, FXO port not configured, or line impedance mismatch. | Ensure PSTN lines are connected to FXO ports. Configure FXO ports in the web interface. Adjust line impedance settings if necessary. |
| Ingen Internett-tilgang | WAN connection issue, incorrect network settings, or modem problem. | Check WAN cable connection. Verify WAN settings (DHCP, Static IP) in the web interface. Restart modem and router. |
| Web Interface Inaccessible | Incorrect IP address, network connectivity issue, or device malfunction. | Ensure computer is on the same subnet as the router. Try default IP address. Check LAN cable. Perform a factory reset if all else fails (Merk: Dette vil slette alle konfigurasjoner). |
