[ENG] Router indicator is red and the internet is disconnected

Step 1: Check Power Connection

1. Check the plug switch:
   • Ensure the electric plug switch is turned on.
   • Wait until the indicator light comes on.
2. Check the power supply of the router:
   • Make sure the router is powered on.
   • Observe until the router indicator light turns on.
3. Test internet connection:
   • Ensure the router is connected to the ISP’s WiFi.
   • Try accessing applications like YouTube.
4. If failed to access YouTube:
   • Check the LAN cable connection from:
     • Router ISP (LAN port) or
     • Wall port or
     • Network switch to Tenda router (WAN port).
5. If still unable to access YouTube:
   • If the cable is from the Wall port or network switch, try plugging the ISP LAN cable directly into the Tenda router.
   • If it still fails, please contact the ISP for further assistance.
