A default gateway is used to allow devices in one network to communicate with devices in another network. In other words, the Default Gateway is that node of your system which forwards packets from your network to outside networks. And mostly wrong network adapter settings, problematic Network Adapter Driver (especially after Windows upgrade ), Virus malware infection or Security Software cause the default gateway is not available error. And when this error occurred on your device, then you will not be able to communicate with an outside network, result not internet access or Limited access.
