How to protect your online privacy, security with VPN while using hotspot

Having a stable internet connection is vital in today’s always-online world. One way to stay connected while on the go is with a hotspot, which uses your cellphone’s cellular network to create its own Wi-Fi network that other devices can connect to.

However, hotspots aren’t the safest way to go online, and they suffer from the same risks that any public Wi-Fi connection does, such as data breaches or misuse by hackers and other nefarious actors.

Although there is an easy way to keep yourself protected when using a hotspot, though, and that’s by using a virtual private network or VPN. It adds an extra layer of security and can keep you safe online. If you do decide to create and use a personal hotspot, remember to always make sure it’s password-protected.

Now, we’ll take you through the benefits of using a VPN with a hotspot and show you step by step how to set up a VPN.

What is a hotspot?

A hotspot refers to a physical location where wireless internet access is available, typically using Wi-Fi technology. It could be a public location like a cafe, airport, hotel or library that offers internet access to its customers or visitors.

Additionally, you can create personal hotspots using your smartphone or other devices, allowing you to share your cellular data connection with nearby devices, such as laptops or tablets, via Wi-Fi. This enables these devices to connect to the internet even when they’re outside the range of a traditional Wi-Fi network.

Hotspots are useful for providing internet connectivity on the go and are commonly used in situations where accessing Wi-Fi networks or wired connections is not possible or convenient.

What is a VPN?

A virtual private network, or VPN, is a technology that creates a secure and encrypted connection between a device, typically a smartphone or laptop and another network over the internet. Here’s how they work.

Encryption

When you use a VPN, all your internet traffic will be encrypted. This means that all data sent and received will be scrambled and protected from any prying eyes.

Routing

All traffic sent through a VPN is routed through a server that is operated by the VPN provider. This server acts as a middleman between your device and all of the websites or online services you access.

Disguising your Identity

By connecting to a VPN server, all of your internet activity will appear to originate from the VPN provider’s server location. For example, if the VPN provider hosts their server in a different country, your traffic will appear in that country, even if you are connecting to the VPN from the United States. This can help you bypass certain geolocation restrictions on websites to access content that might otherwise be unavailable in a specific region.

Privacy on Public Wi-Fi

When connected to a public Wi-Fi network, which is always risky, a VPN will shield your browsing activity from potential hackers and snoopers. Here are some mistakes to avoid if you have to use public Wi-Fi.

Choosing a VPN provider

Using a VPN with a mobile hotspot is a great way to keep yourself protected, as we’ve shown above. Fortunately, these days, there is a wide range of VPN providers. See my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android & iOS devices.

Luckily for users, setting up a VPN isn’t difficult at all. Once you’ve picked your provider, here’s what you will want to do next.

Install the VPN application

Once you’ve selected a VPN, you’ll want to install the application on your device. Always make sure you are downloading directly from the developer or a trusted intermediary such as the Apple App Store or Google Play Store. 

Create an account

After you’ve installed your VPN application and opened it for the first time, it’s time to create your account. The majority of VPN services will require you to create a username and password with an email address.

Select server location

Now that you have an account, you can begin using your new VPN. The first step in any VPN application is to select your server location. While there are advantages to picking a location further away, such as bypassing geo-location locks on specific content, it’s best to pick a server location that’s close to you. This will allow you to experience the optimal speed while browsing securely with a VPN.

Test the connection

After the initial application, you can launch your VPN application anytime you want to create a secure network. However, it’s important to note that if you want to use your phone to create a mobile hotspot, and you want to access the internet from that hotspot on your laptop, you will need to have the VPN installed and operating on both devices. This is because security protocols of both iOS and Android do not allow multiple devices to share the same VPN IP address. 

This process is simpler than it may sound, simply install whichever VPN service you prefer on both devices, log into your account and select the same VPN server location for a faster and more stable connection on both devices. After that, you just need to make sure the connection is working. Once you have a VPN actively running on any mobile device, it will encrypt the data between the network and you, you just need to simply open a browser and make sure you have an internet connection.

This pasta sauce wants to record your family

This pasta sauce wants to record your family

As if there weren’t already enough devices listening in on everything being said in your home, Prego, the pasta and pizza sauce brand, is releasing a device designed to record everything said around the dinner table for posterity. The Connection Keeper, which looks like an oversized pasta jar lid, was created in collaboration with StoryCorps, the nonprofit organization focused on preserving the stories of Americans in a collection housed at the Library of Congress’ American Folklife Center. There’s no AI, Wi-Fi, or Bluetooth, but you can optionally upload recordings to StoryCorps’ website to make them easier to share with family.

Prego says the goal of the device is to encourage families to make memories through conversation during dinner instead of staring at their phones — but only for a small number of families. The company is only planning to make less than 100 of them. The Connection Keeper will be available for purchase online starting on April 27th for $20 as part of a bundle that includes the device, a jar of Prego sauce, spaghetti noodles, and a deck of cards featuring conversation prompts and ideas.

Using the device is as easy as plopping the Connection Keeper down in the middle of everyone at the table and pressing one button to start recording. Using a pair of microphones, it captures CD-quality audio to a 16GB microSD card for up to eight hours when fully charged.

When dinner’s over, the recordings can be transferred to a computer over USB-C and then uploaded to a dedicated microsite created by StoryCorps where they’re preserved and accessible only by the uploader, unless they choose to share them with other StoryCorps users or the general public. You even have the option to archive them within the Library of Congress, which makes them public automatically, so hopefully your family talks about more than just stealing brainrots.

The recordings can be accessed on a smartphone through the StoryCorps app, but Prego intentionally left phones out of the rest of the process to discourage their use at the table. It’s also why the Connection Keeper lacks a screen. The goal was to minimize interactions with the device so family members instead focused on talking with each other.

BMW puts humanoid robots to work building EVs

NEWYou can now listen to Fox News articles!

BMW Group has spent years testing automation, but this latest move feels different. Instead of robotic arms locked in cages, the company is now using humanoid robots that move through factories more like people. After a successful pilot in Spartanburg, South Carolina, BMW is bringing that same idea into its Leipzig, Germany, factory, where it is testing robots in real production environments. This time, it is partnering with Hexagon Robotics to introduce a new generation of AI-powered machines. Unlike many robot demos you see online, this one is already being tested inside a real production environment.

How BMW’s humanoid robot pilot built over 30,000 vehicles

BMW’s earlier pilot used Figure 02 humanoid robots for a very specific task. They handled the precise positioning of sheet metal for welding on the BMW X3 production line. That task may seem small, but it plays a key role in keeping production moving smoothly. Precision work like this can easily slow things down or create bottlenecks. According to BMW, those robots helped contribute to building more than 30,000 vehicles. Because of that success, the company now feels confident about expanding the concept. Instead of limiting testing to one plant, BMW is moving forward with its iFACTORY initiative in Leipzig, where EV production is already a major focus.

BMW’s new AI humanoid robots for EV factories

The new robots, called AEON, come from Hexagon Robotics. They are designed to work inside active factory environments without constant human direction. They rely on AI-based motion control, which helps them move through complex spaces. At the same time, built-in sensors allow them to understand their surroundings in real time. Because of that, they can adjust their actions on the fly instead of following fixed instructions. Hexagon refers to this as “Physical AI.” In simple terms, the robot can make decisions based on what it sees around it. As a result, the robot does not stop when something unexpected happens. Instead, it adapts and keeps working. That marks a clear shift from traditional factory automation.

Why BMW is investing in humanoid robots now

BMW executives have made it clear that this is not about replacing people overnight. Instead, the goal is to test what actually works in real production environments. Michael Nikolaides, who oversees BMW’s production network, says these pilot programs help the company refine how AI-powered robots learn on the job. He goes on to point to a broader vision, saying: “Digitalization improves the competitiveness of our production, here in Europe and worldwide. The symbiosis of engineering expertise and artificial intelligence opens up entirely new possibilities in production.” There is also a practical reason for the humanoid design. Factories are already built for human workers. Because of that, a robot that can use the same spaces and tools is much easier to integrate than one that requires a complete redesign.

How humanoid robots could transform factory work

For years, humanoid robots felt more like something you saw in those social media demo videos than something you would trust on a real factory floor. Yes, they looked impressive, but they struggled in real environments. That is starting to change. Factories are still unpredictable. Parts do not always arrive in the exact same position. Workers move around constantly, and tools and materials shift throughout the day. Because of this, traditional robots often struggle since they rely on tightly controlled conditions. AI-powered humanoid robots can handle that kind of variability. They move around people and equipment without stopping. They adjust when parts are slightly off, and they work in spaces built for human workers.  That level of flexibility is what sets this new wave of AI-powered robotics apart from earlier forms of automation.

What this means to you

Even if you never step inside a factory, this shift still matters. For one, it could change how cars are built, whether they are electric or gas. When production speeds up, costs can come down over time, which could affect what you pay for your next vehicle. At the same time, factory jobs are likely to change. Some repetitive or physically demanding work may move to robots. In many cases, that means people shift into roles focused on oversight, maintenance or more skilled tasks. Step back for a second, and you can see this is a sign of where AI is headed next. It is no longer limited to apps on your phone or software on your computer. Now, it is starting to show up in the physical world in ways you can actually see and interact with.

Kurt’s key takeaways

BMW is not the only company testing humanoid robots, but it is one of the first to bring them into real production environments. That is a big shift from the testing phase most of us are used to seeing. The fact that these robots are already helping build tens of thousands of vehicles shows that this is moving beyond early trials. It is starting to become part of how factories actually run. Where this goes next is still an open question. If the technology keeps improving, you could see more of these robots show up in factories and warehouses over time.

So here is the bigger question. How do you feel about humanoid robots working alongside people in factories? Would you trust them to help build the car you drive? Let us know by writing to us at Cyberguy.com

Blue Origin successfully reused its New Glenn rocket

Today’s launch of AST SpaceMobile’s BlueBird 7 satellite aboard Blue Origin’s reusable New Glenn rocket was a partial success. The New Glenn touched down on its landing pad without incident, making it the second launch and landing for the first stage booster, and officially giving Jeff Bezos a reusable launch vehicle. Unfortunately for AST SpaceMobile, the mission was less successful. Its cell-tower-in-space was delivered to a lower orbit than expected by the second stage of the launch vehicle, rendering it functionally useless.

While the satellite separated from the launch vehicle and powered on, the altitude is too low to sustain operations with its on-board thruster technology and will de-orbited.

Bezos, for his part, posted a video of the landing on X without comment.
