VPN Types: The Good, the Bad, and the Ugly



If you're in any way concerned about your online privacy, you must have heard about VPNs. In simple terms, a VPN (Virtual Private Network) is an online tool that allows you to mask your internet traffic and location. There are several VPN types available, but they are not all equal. Here's a rundown of the good, the bad, and the ugly VPN types you need to know about.


The Good: Paid VPNs



Paid VPN services are the most reliable and secure option. Unlike free VPNs that often come with hidden agendas, paid VPNs are transparent about their operations and take user privacy seriously. They generally offer strong encryption, high-speed connections, and are compatible with multiple devices. Some notable options include ExpressVPN, NordVPN, and ProtonVPN.


The Bad: Free VPNs



Free VPNs might be tempting, but they come with several downsides. First, most of them rely on advertising to fund their operations, meaning that they sell your data to third-party advertisers. Second, free VPNs typically have slow speeds and data caps since they prioritize their paid subscribers. Finally, some free VPNs have been known to install malware and viruses on users' devices. If you must use a free VPN, ensure that you read through their privacy policies to understand how they handle users' data.


The Ugly: Browser VPNs



Browser VPNs are VPNs that are built into web browsers such as Opera and Chrome. While these VPNs are convenient, they are not secure. Browser VPNs typically offer weak encryption, meaning that your connection can still be traced. Additionally, since they only mask your browser traffic, your other online traffic remains exposed. If you prioritize your online privacy and security, browser VPNs are not the way to go.



In conclusion, not all VPN types are equal. Paid VPNs are the most reliable and secure option, while free VPNs and browser VPNs have several risks. When considering a VPN, always prioritize your privacy and security. Choose wisely.

Router reset button

When it comes to troubleshooting internet connection issues, one of the first things tech support will suggest is resetting the router. But what exactly happens when you press that small, inconspicuous button on the back of your router?


Firstly, it's important to note that resetting your router will erase all your settings and revert it back to its default factory settings. This means that any custom settings, such as your Wi-Fi network name and password, will be lost.


The reset button is typically a small hole on the back or bottom of the router, and is pressed using a paperclip, pen, or similar object. Pressing and holding the button for around 10 seconds will initiate the reset process.


So why is resetting the router so effective in resolving connectivity issues? For starters, it clears the device's cache and memory, allowing it to start fresh with no residual data. This can help to resolve issues such as slow speeds or dropped connections, which may be caused by a buildup of outdated settings or corrupted data.


In addition, resetting the router can also clear any conflicts or issues that may have arisen between the device and its connected devices (such as laptops, smartphones, and tablets).


It's important to note that while resetting your router can be an effective troubleshooting step, it should not be your first port of call. Before resetting, be sure to try other simple fixes such as power cycling the router and checking cables and connections.


Overall, the reset button on your router can be a powerful tool in resolving internet connectivity issues. Just be sure to use it wisely and as a last resort.

Router default login

When setting up a new router, one of the first things you'll need to do is access the router's settings. To do this, you'll need to log in using a default username and password. While manufacturers commonly provide these details in product manuals, not all users take the time to change them for security reasons. This has created a vulnerability that hackers exploit to gain access to connected devices



It's important to remember that routers serve as gatekeepers that protect your network from external threats. Accessing the router's settings is not only critical to configuring your network's parameters, but it also lets you see who is connected to your network and monitors traffic flow. This makes it essential to take care in setting up the login details


Default login details vary from manufacturer to manufacturer. Some use "username" and "password" as the login credentials. Others might use "admin" for the username and "password" or "1234" for the password. Once logged in, you can change the username and password to something unique and difficult to guess


Using a strong password that is difficult to guess or crack is essential. Avoid using common, easy-to-guess words or combinations such as "password," "admin," "1234," or your name, birthday, or address. Instead, use a combination of uppercase and lowercase letters, numbers, and special characters. A good example would be something like "C9#f&gHt#k" or another random sequence of letters and characters that are more challenging to guess


Conclusion


With the rise of home automation and smart devices connected to Wi-Fi networks, router security has become more critical than ever. By customizing default login settings, users can dramatically reduce the risk of cyberattacks and protect their devices from unwanted intrusion. As such, it's important that you take the time to change default login details when you set up a new router. Doing so can ensure that you keep prying eyes out of your network.
