Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Internet Access | DSL line not connected, incorrect ISP settings, modem not synced. | Check DSL cable connection. Verify ISP settings in the router's web interface. Restart the router and wait for DSL sync. Contact your ISP if the issue persists. |
| Weak Wi-Fi Signal | Router placement, interference, too many devices. | Relocate the router to a central, open area. Avoid placing near other electronics. Consider adding a Keenetic Wi-Fi Mesh extender. |
| Cannot Access Router Web Interface | Incorrect IP address, network configuration issues. | Ensure your device is connected to the router. Try my.keenetic.net or 192.168.1.1. Clear browser cache. Try a different browser. If all else fails, perform a factory reset (see below). |
| Slow Internet Speed | Network congestion, outdated firmware, ISP issues. | Update router firmware. Limit bandwidth-intensive activities. Perform a speed test directly connected to the router. Contact your ISP. |
Factory Reset
If you encounter persistent issues, you may need to perform a factory reset. This will erase all custom settings and restore the router to its default configuration.
- With the router powered on, locate the Reset button (usually a small pinhole button) on the back panel.
- Use a paperclip or a thin object to press and hold the Reset button for approximately 10 seconds until the system LED blinks rapidly.
- Release the button and wait for the router to restart. You will then need to reconfigure the router from scratch.
