The reason for your Dodo internet not working and offline could be because of various reasons and factors, I will discuss a few troubleshooting techniques to resolve the problem. Kindly, follow them carefully:
1. Check Your Wired Connection: In order to find the reason behind your internet connectivity, first check if all the wires connecting your router, modem, and computer are in perfect working condition. Also, make sure that the DSL cable from your ISP is not damaged. Replace any wire with damage and see if the issue is resolved.
2. Check Your Internet Connection: At times the issue of connectivity could arise if any repair work or maintenance is going on. So make sure that you have an internet connection and the problem is in either router or modem.
Connect your router to the computer using the ethernet cable where the DSL cable goes into the WAN port. Try opening a website, if yes then move onto next step, otherwise call your ISP.
3. Update Driver/Firmware: Drivers and Firmware are software program written into your router device to control its functionalities. These software programs are vulnerable to getting corrupt or getting out-dated.
So go to your vendor's official website and download all the latest available driver and firmware updates. Install them and see if the issue is resolved.
4. Reset Your Router: If any of the above-mentioned steps did not help you resolve the issues then chances are, there might be some internal software snag. In these circumstances we recommend the user to reset the device to wipe-out any internal conflicts.
Press the "Reset" button at the back of your router for 20-30 seconds and then reconfigure it as per your network guidance.
