Question:

I have an issue with my ASUS RT-AX3000 router, which is unable to connect to the internet despite having a strong wifi signal. I have another router, the ASUS RT-AC68U, which works fine as a node. I checked the WAN IP address of the RT-AX3000 and it shows 0.0.0.0, while the RT-AC68U has a valid IP address. I suspect there is a problem with the ISP or the router configuration. I also cannot access the web interface or the app to change any settings, even after performing multiple factory resets. What could be the cause of this problem and how can I fix it? Should I contact ASUS or Spectrum (my ISP) for support?

Answer:

How to fix an ASUS RT-AX3000 router that cannot connect to the internet

If you have an ASUS RT-AX3000 router that cannot connect to the internet, you might be experiencing one of the following issues:

• Your ISP (Internet Service Provider) is having an outage or a problem with their network.
• Your router is not configured properly to obtain an IP address from your ISP.
• Your router is faulty or damaged.

In this article, we will explain how to troubleshoot each of these issues and provide some possible solutions.

The first thing you should do is to check if your ISP is having any problems with their service. You can do this by visiting their website, calling their customer support, or checking their social media accounts. If there is an outage or a maintenance in your area, you might have to wait until they restore the service.

You can also try to connect another device, such as a laptop or a smartphone, directly to your modem using an Ethernet cable. If the device can access the internet, then the problem is not with your ISP, but with your router.

Configure your router to obtain an IP address

If your ISP is working fine, but your router still cannot connect to the internet, you might need to configure your router to obtain an IP address from your ISP. An IP address is a unique identifier that allows your device to communicate with other devices on the internet. If your router does not have a valid IP address, it cannot establish a connection.

To check your router’s IP address, you can use the ASUS Router app on your smartphone or tablet. The app will show you the status of your router and its WAN (Wide Area Network) IP address. If the WAN IP address is 0.0.0.0, it means that your router is not getting an IP address from your ISP.

To fix this, you can try to reboot your router and your modem. Sometimes, this can refresh the connection and resolve the issue. To reboot your router and your modem, follow these steps:

• Unplug the power cord of your router and your modem from the wall outlet.
• Wait for about 30 seconds.
• Plug the power cord of your modem back into the wall outlet and wait for it to fully restart.
• Plug the power cord of your router back into the wall outlet and wait for it to fully restart.
• Check your router’s WAN IP address using the ASUS Router app. If it is still 0.0.0.0, proceed to the next step.

If rebooting your router and your modem does not work, you might need to manually configure your router to obtain an IP address from your ISP. To do this, you will need to access your router’s web interface using a web browser on a device that is connected to your router’s wifi network. To access your router’s web interface, follow these steps:

• Open a web browser on your device and enter http://router.asus.com in the address bar. This will take you to the login page of your router’s web interface.
• Enter your router’s username and password. The default username and password are both admin. If you have changed them, use the ones you have set.
• Once you are logged in, go to the Advanced Settings menu and select WAN.
• Under the WAN Connection Type section, select the option that matches your ISP’s connection type. For example, if your ISP uses a cable modem, select Automatic IP. If your ISP uses a DSL modem, select PPPoE. If you are not sure what your ISP’s connection type is, contact them for more information.
• Under the WAN IP Setting section, make sure that the Get the WAN IP automatically option is checked. This will allow your router to obtain an IP address from your ISP automatically.
• Click Apply to save the changes.
• Check your router’s WAN IP address using the ASUS Router app. If it is still 0.0.0.0, proceed to the next step.

If manually configuring your router to obtain an IP address from your ISP does not work, you might need to clone your MAC address. A MAC address is another unique identifier that is assigned to your device’s network interface. Some ISPs use MAC address filtering to authenticate their customers and prevent unauthorized access. If your router’s MAC address does not match the one that your ISP has registered, you might not be able to connect to the internet.

To clone your MAC address, you will need to find out the MAC address of a device that can access the internet through your modem, such as a laptop or a smartphone. To find out the MAC address of your device, follow these steps:

• On a Windows laptop, open the Command Prompt by pressing the Windows key and R key at the same time, typing cmd, and clicking OK. Then, type ipconfig /all and press Enter. Look for the Physical Address of your Ethernet adapter or Wireless adapter. This is your MAC address. It should be a 12-digit hexadecimal number, such as 00-11-22-33-44-55.
• On a Mac laptop, open the Terminal by going to Applications > Utilities > Terminal. Then, type ifconfig and press Enter. Look for the ether of your en0 or en1 interface. This is your MAC address. It should be a 12-digit hexadecimal number, such as 00:11:22:33:44:55.
• On an Android smartphone, go to Settings > About phone > Status. Look for the Wi-Fi MAC address. This is your MAC address. It should be a 12-digit hexadecimal number, such as 00:11:22:33:44:55.
• On an iPhone, go to Settings > General > About. Look for the Wi-Fi Address. This is your MAC address. It should be a 12-digit hexadecimal number, such as 00:11:22:33:44:55.

Once you have found out the MAC address of your device, you can clone it to your router using the web interface. To clone your MAC address, follow these steps:

• Access your router’s web interface using a web browser on a device that is connected to your router’s wifi network.
• Log in with your router’s username and password.
• Go to the Advanced Settings menu and select WAN.
• Under the WAN IP Setting section, click on the MAC Address button.
• Enter the MAC address of your device in the MAC Address field. Make sure to use the same format as your device, such as 00-11-22-33-44-55 or 00:11:22:33:44:55.
• Click Apply to save the changes.
• Check your router’s WAN IP address using the ASUS Router app. If it is still 0.0.0.0, proceed to the next step.

Contact ASUS or Spectrum for support

If none of the above solutions work, you might have a faulty or damaged router that needs to be repaired or replaced. You can contact ASUS or Spectrum for support and see if they can help you with your issue. You can find their contact information on their websites or on your router’s user manual.
