Can I leave default gateway blank?
|
In this Hands-on Networking Training Series, we learned all about Network Address Translation in detail along with examples in our previous tutorial. Show In this tutorial, we will discuss the concept of the default gateway and its role in the computer networking systems. Many times while surfing on the Internet and exploring websites we encounter with an internet connection problem, and when we try to search the reason, we get a caution that the ”default gateway is not available” now let’s gain the knowledge on what does it mean and how to resolve it.  What You Will Learn: What is the Default Gateway?A default gateway is a router or network node in the computer networking system which behaves as a forwarding hop to the other networking system when not any next hop IP address is specified in the routing table for the forwarding of a data packet to the destination host. Thus the default gateway will act as an access point to the other networks when one network wants to communicate or send data packets to another network. This also includes the alteration of IP addressing and subnet mask of the system and network topologies.

If the IP packet at some instance of the node doesn’t find the suitable set of rules and route to be followed to deliver the packet to the destination address, then it will choose the default gateway for the further routing process. Thus the default gateway is itemized by a set of particular configurations which are known as the default route. In the small offices or home networks, the router which will link up the LAN network to the Internet behaves like a default gateway for all the network components.

By disabling and then enabling the Wi-Fi from the network and Internet sharing menu, you can fix the issue. The steps involved are as follows:
Solution 3: Update your Network adapter drivers. You need to update the latest version of the network adapter drivers on your PC if you are getting the caption that “default gateway is not available”. This is one of the solutions but it doesn’t mean that it will surely resolve your issue.

The steps are as follows:
If the automated search doesn’t get any suitable result, then manually search for the updated software and then download it. This will fix the issue.

The auto-logon is a newly introduced feature of the windows account of the user that would repeatedly log in and this was being used before the shutdown of the PC. This feature will conflict with the windows network settings feature and hence the “default gateway is not available” issue arises. In order to fix it, disable the feature or you can put a password to log in so that every time when it boots up, it will require a password and will not automatically take it. Solution 5: Uninstall your network adapter drivers. It is also one of the popular solutions to fix the “default gateway is not available” issue. You need to completely uninstall the network drivers from your computer. One should not be concerned about the effect of the non-existence of the drivers as when you reboot your system the windows will detect the drivers and reinstall them. The steps included are as follows:
Solution 6: Change the network adapter drivers. It is one of the lengthy and complicated processes of fixing “the default gateway is not available to issue”. In this process, we will exchange the network adapter drivers with some different set of drivers which are previously installed in the system. The steps are as follows:
Solution 7: Change the frequency of the Wireless Router. The new generation router works on 5GHz frequency, but many times the adapter that you are using will not support this frequency. Hence change the frequency from 5GHz to 2.4GHz and this will resolve the gateway issue. The process of changing the frequency will be given in the router manual, thus one can go through the steps mentioned and make changes.

We hope you enjoyed the entire range of tutorials in this networking series. We are sure that this series of tutorials would indeed be the best guide for any beginner or experienced person!! What happens if you leave the default gateway blank?Without the gateway, the PC can't get to another network, and devices on another network may be able to send something to that PC, but that PC can't reply, and it can't establish something like a TCP session.
Can you leave gateway blank?In the Windows configuration for a network adapter you can leave the default gateway blank. Linux has no problem if you want to delete the default route, or not specify one. The default gateway address will only come into play if a system is trying to reach a subnet that's not currently on any network adapter.
Should default gateway be blank?Why is my default gateway blank? There are a couple of reasons. First, it could be because the laptop or PC has been set to use a static IP address. Second, it could be a problem with your router or any other network hardware.
Can 0.0 0.0 be a default gateway?In IPv4-based routing, 0.0. 0.0 serves as a default route. This means no particular address has been designated in the routing table as the next hop in the packet's path to its final destination.
