How to Secure Your Home Wifi Network
In the past couple of years, WiFi has become the de facto standard of internet connectivity at homes. Even broadband companies have been offering WiFi devices within their packages.
There are also different ways you can get your internet at home. Most common is via cable, but there are people who also use a mobile network at home. It doesn’t really matter which connection you use in terms of how secure your network is. What you should always do is check the settings of the device that shares your WiFi. I will go over the most common principles that you should check. This way you can be sure that your WiFi is secure and it’s not being used by random people.
What Are The Dangers Of Having WiFi?
Well a stranger might be monitoring your devices that are connected to the internet. They might even gain access to your personal information, such as your usernames and passwords. So it’s not just you that will be in danger. It can affect everyone that’s connected to the WiFi at your home.
A hacker can use an unsecure network to attack other internet users or websites. This type of an open network also provides a place to upload any type of illegal content. But in the end, you will be at fault, since the connection comes from you.
A random person might upload massive files or watch movies while connected to your WiFi. This, in return, makes your internet connection much slower.
A mobile network usually comes with a set limit to bandwidth. Having a stranger use your network, might mean that you will run out of bandwidth much faster. Which means that you are pretty much forced to pay for extra. Some 3G and 4G routers also allow you to send text messages. A hacker can use this feature to subscribe to websites and different memberships.
How To Keep My WiFi Safe?
- First connect your computer to the wireless router with a network cable
- Open your browser
- Type in your routers IP address
- Log in
The username and password is usually written underneath the router. If it’s not, then you should check the user manual that came with it. Or you can also google the routers serial number. Some companies have a standard log in information that you can use to log in, unless it’s been changed.
The connection between your computer and the router is usually encrypted. All of the newer routers offer a strong WPA2 encryption. If your router is only offering a WEP encryption, then it’s time to buy a newer version.
When picking the type of encryption, you also get an option to choose a new WiFi password. A decent password includes letters in caps, numbers and even symbols. The most recommended length is at least 9 characters.
PS! HOME1234 is not a safe password!
Router companies use two methods to name WiFi networks. One is based on the brands name with random symbols and the other usually includes your broadband name. For example Huawei421e8 or Comcast_43AR42. It doesn’t matter which type you have, it’s always recommended to change them to anything else. There are instances where certain router brand usernames and passwords have been leaked. I also don’t recommend choosing your own name or your address as the networks name. Go with something random instead.
When you are changing the name of your network, there is also an option for making it invisible. You can still keep using all of the devices connected to it. However, if you want to connect any new devices, then you’ll need to manually write the name of the WiFi and password.
All network cards have a unique network address, which is also known as MAC. Your routers user interface will display all the MAC addresses connected to the network. You can use this to check that only the allowed devices are connected to it.
Some broadband routers also allow you to gain access to the administration panel via WiFi. I recommend disabling that option. It’s much safer if you can only access it with a physical cable.
Outside attacks can be blocked by the routers built-in firewall. Make sure that it’s been enabled.
All of the tips mentioned above are meant for those who are comfortable with computers and configuring settings. If you have any doubts or questions on what a certain button or command does in the router settings, then I recommend reaching out to your network provider and asking them for help.
