How to fix Cisco Network Router when internet is not working at all?
- DDaniel JonesAug 20, 2025
First, ensure the router power supply reads 'Output 12V'; otherwise, it won't function correctly. Check if the 'Power/SYS' light is on. If not, ensure the power cable is securely plugged in and both the router and power point are switched on. Also, make sure all cables to and from the router are securely plugged into the wall and other devices. If the issue persists, turn the router off for about 30 seconds, then switch it back on.
