Router Security

People are always buying new Devices that come onto the market, and everyday they add security to those devices in the form of Passwords and Two Factor Authentication.
However, there is one Device on a lot of Networks that always gets overlooked. That Device is the Home Router. This could also be true of small/large businesses that get broadband installed. Perhaps they just wanted to get the system up and running, and planned to change the default settings later but never got around to it.

Until recently, I was one such person. My broadband was installed a little while ago, and whilst a Password was required to access the Network, the Administrator credentials for the Router were the default settings.
Through conducting a Google search, I found that the Administrator Credentials for my Router were the first results found by the Search Engine.

To change the settings for your Router, you’ll need to login to the interface via a Web Browser. If you don’t know the IP Address of your Router, it can be found by running the Command: ipconfig /all

In the data that is displayed, you need to look for the Default Gateway Address. This is another name for the Router, it is in essence, a gateway for incoming and outgoing traffic on your Network. The ip address for your Router will probably look something like this: This is a local address and will only be accessible whilst you are connected to the Network.
Once you have the address you’ll need to type it into the browser, to access the page.
Only change the settings that you are sure won’t break anything. Changing the default Passwords will make your network more secure. However, changing what channels 2.4Ghz and 5.0Ghz run at, may reduce the performance of your Network or cancel it out all together. If you’re unsure, save a copy of the Default Configuration to your computer before changing any settings. That way if anything goes wrong, you can factory reset the Router and then reinstall the Configuration you saved, reducing any inconvenience to other users on the Network.

If you have a lot of people who want to use your network, it maybe an idea to setup a separate Network for them to use. e.g. A Guest Network.
This runs parallel to your own Network. However, you have greater control over how this is used. For example; You can apply certain web filters, or set limits on the data streaming, reducing how much data they can upload and download whilst connect to your Network.
