Reset TCP/IP Settings

To reset TCP/IP settings, type “netsh int ip reset” into Command Prompt and press Enter. This will reset all TCP/IP settings to their default state. Restart your computer and check if the default gateway error is resolved. If not, try resetting your router by unplugging it for 30 seconds and plugging it back in. If you still have issues, try updating your network adapter driver. If you’re using a TP-Link router, try disabling the DDNS feature. Additionally, check if your iPhone is connected to the same network and see if it can find the default gateway. On Linux, use the command “sudo service network-manager restart” to reset network settings. If you’re using Azure VPN, try resetting the connection in the Azure portal.

A missing gateway IP address can cause a range of connectivity issues, including limited internet access and difficulty accessing network resources.

ipconfig /all

This command will display the current network configuration of the device including the IP address, subnet mask, and gateway IP address.

2. Ping the gateway: If the gateway IP address is set correctly but the device is still unable to connect to the internet, the next step would be to ping the gateway to ensure that it is reachable. This can be done using the following code:

ping

If the gateway is reachable, the device should receive a response from the gateway. If the gateway is not reachable, there may be an issue with the network connection or the gateway device.

3. Reset network adapter: If the issue persists, the next step would be to reset the network adapter on the device using the following code:

netsh winsock reset

This command will reset the network adapter and clear any existing network settings or configurations.

4. Restart device: If none of the above steps resolve the issue, the last step would be to restart the device. This can be done using the following code:

shutdown /r

This command will restart the device and may resolve any network connectivity issues.
