Ethernet vs Wi-Fi security comparison reveals surprising results for home users seeking protection

NEWYou can now listen to Fox News articles!

We spend so much time online that how we connect to the internet has become almost as important as the devices we use. Most people never give it a second thought. They connect their computer to Wi-Fi, type in a password and get on with their day. But if you have ever wondered whether plugging in an Ethernet cable is safer than sticking to wireless, you are asking the right question. The way you connect can have real consequences for your privacy and security. Recently, Kathleen reached out to me with the same doubt.

“Is it more secure to use the Ethernet connection at home for my computer, or is it safer to use the Wi-Fi from my cable provider?”

It’s a great question, Kathleen, because both options seem similar on the surface but work very differently under the hood. Those differences can mean the difference between a private, secure connection and one that’s more vulnerable to attackers.

How Ethernet and Wi-Fi differ when it comes to security

Ethernet and Wi-Fi both get you online, but they do it in completely different ways. Ethernet uses a physical cable that connects your computer directly to the router. Since it is a wired connection, data travels straight through that cable, making it much harder for anyone to intercept it. There is no wireless signal to hijack, no airwaves to eavesdrop on.

Wi-Fi, on the other hand, is built on convenience. It sends your data through the air to and from your router, which is what makes it so easy to connect from anywhere in your home. But that convenience comes with more risk. Anyone within range of your signal could potentially try to break into the network. If your Wi-Fi is protected by a weak password or uses outdated encryption, a skilled attacker might gain access without ever stepping inside your house. 

At home, that risk is smaller than in a coffee shop or hotel, but it is not zero. Even a poorly secured smart device on your network can give attackers a way in. Ethernet removes many of those risks simply because it is harder to access a connection that requires physical access to a cable. Check out our steps for setting up a home network like a pro here.

DON’T USE YOUR HOME WI-FI BEFORE FIXING CERTAIN SECURITY RISKS

Why one connection might be safer than the other

It is easy to think Ethernet is automatically safer, but that is not the whole story. Your real security depends on how your entire network is set up. For example, a Wi-Fi network with a strong password, up-to-date router firmware, and WPA3 encryption is going to be far more secure than a poorly configured Ethernet setup connected to an outdated router.

There is also the question of who else uses your network. If it is just you and a handful of devices, your risk is low. But if you live in a shared space or run smart home gadgets, that changes the equation. Each device connected to Wi-Fi is a potential entry point. Ethernet reduces the number of devices that can connect, which limits the attack surface.

Ultimately, the connection type is one piece of the puzzle. The bigger factors are how your router is configured, how often you update your software, and how careful you are with what devices you connect.

6 ways to make your internet safer

Whether you stick with Wi-Fi or switch to Ethernet, there are several practical steps you can take to protect your devices and data. Each step adds an extra layer of security to your network.

IS YOUR HOME WI-FI REALLY SAFE? THINK AGAIN

1) Use a strong network password

Choose a long and unique password for your Wi-Fi. Avoid obvious choices like your name, address, or simple sequences. A strong password makes it far harder for attackers to guess or crack your network. A password manager helps you create and store strong, unique passwords for every account, reducing the chances of a hacker gaining access through weak or repeated credentials.

Next, see if your email has been exposed in past breaches. Our #1 password manager (see Cyberguy.com/Passwords) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

2) Enable the latest encryption on your router

Most modern routers support WPA3, which is much more secure than older standards like WPA2. Check your router’s settings to enable the latest encryption and ensure your network traffic is harder to intercept.

3) Keep your router firmware updated

Router manufacturers regularly release updates that patch security vulnerabilities. Log into your router’s admin panel occasionally to check for updates and install them as soon as they are available. This prevents attackers from exploiting known flaws. 

10 WAYS TO SECURE YOUR OLDER MAC FROM THREATS AND MALWARE

4) Review connected devices

Regularly check which devices are connected to your network and disconnect anything you no longer use. Each connected device is a potential entry point for attackers, so keeping the list limited reduces your network’s exposure.

5) Install strong antivirus software

Even on a secure network, malware can sneak in through downloads, phishing attacks, or compromised websites. A strong antivirus program will detect and block malicious activity, protecting your computer before damage occurs.

The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

6) Use a VPN for sensitive tasks

A virtual private network encrypts your internet traffic, making it unreadable to outsiders. This is especially useful if you ever use Wi-Fi in public or need an extra layer of privacy at home. A reliable VPN is essential for protecting your online privacy and ensuring a secure, high-speed connection.

Kurt’s key takeaway

So, which is safer, Ethernet or Wi-Fi? Ethernet wins in raw security because it eliminates many of the risks that come with wireless connections. But in a well-secured home network, the difference is often smaller than most people think. What matters more is how you manage your devices, passwords, software, and online habits.

Meta expands nuclear power ambitions to include Bill Gates’ startup

These AI projects include Prometheus, the first of several supercluster computing systems, which is expected to come online in New Albany, Ohio, sometime this year. Meta is funding the construction of new nuclear reactors as part of the agreements, the first of which may come online “as early as 2030.” These announcements are part of Meta’s ongoing goal to support its future AI operations with nuclear energy, having previously signed a deal with Constellation to revive an aging nuclear power plant last year.

Financial information for the agreements hasn’t been released, but Meta says that it will “pay the full costs for energy used by our data centers so consumers don’t bear these expenses.”

“Our agreements with Vistra, TerraPower, Oklo, and Constellation make Meta one of the most significant corporate purchasers of nuclear energy in American history,” Meta’s chief global affairs officer, Joel Kaplan, said in the announcement. “State-of-the-art data centers and AI infrastructure are essential to securing America’s position as a global leader in AI.”

Why January is the best time to remove personal data online

Why January is the best time to remove personal data online

NEWYou can now listen to Fox News articles!

January feels like a reset. A new calendar. New goals. New habits. While you clean out your inbox, organize paperwork or set resolutions, however, scammers also hit reset, and they start with your personal data.

That is because January is one of the most important months for online privacy. This is when data brokers refresh profiles and scammers rebuild their target lists.

As a result, the longer your information stays online, the more complete and valuable your profile becomes. To help address this, institutions like the U.S. Department of the Treasury have released advisories urging people to stay vigilant and avoid data-related scams. 

For that reason, taking action early in the year can significantly reduce scam attempts, lower identity theft risks, and limit unwanted exposure for the rest of the year.

STOP DATA BROKERS FROM SELLING YOUR INFORMATION ONLINE

Why personal data does not expire and keeps compounding online

Many people assume old information eventually becomes useless. Unfortunately, that’s not how data brokers work.

Data brokers don’t just store a snapshot of who you are today. They build living profiles that grow over time, pulling from:

Advertisement
  • Public records (property sales, court filings, voter registrations)
  • Retail purchases and loyalty programs
  • App usage and location data
  • Past addresses, phone numbers, and relatives
  • Marketing databases and online activity.

Each year adds another layer. A new address. A changed phone number. A family connection. A retirement milestone. On its own, one data point doesn’t mean much. But together, they create a detailed identity profile that scammers can use to convincingly impersonate you. That’s why waiting makes things worse, not better.

Why scammers ‘rebuild’ targets at the start of the year

Scammers don’t randomly target people. They work from lists. At the beginning of the year, those lists get refreshed.

Why January matters so much:

  • Data brokers update and resell profiles after year-end records close
  • New public filings from the previous year become searchable
  • Marketing databases reset campaigns and audience segments
  • Scam networks repackage data into “fresh” target lists.

Think of it like the upcoming spring cleaning, except it’s criminals organizing identities to exploit for the next 12 months.

If your data is still widely exposed in January, you’re far more likely to:

Once your profile is flagged as responsive or profitable, it often stays in circulation.

As personal information accumulates across databases, digital profiles grow more detailed and more valuable to scammers over time. (Kurt “CyberGuy” Knutsson)

Why taking action in January protects you all year long

Removing your data early isn’t just about stopping scams today; it’s about cutting off the supply chain that fuels them. When your information is removed from data broker databases:

  • It’s harder for scammers to find accurate contact details
  • Phishing messages become less convincing
  • Impersonation attempts fail more often
  • Your identity becomes less valuable to resell.

This has a compounding benefit in the opposite direction. The fewer lists you appear on in January, the fewer times your data gets reused, resold, and recycled throughout the year. That’s why I consistently recommend addressing data exposure before problems start, not after.

Why retirees and families feel the impact first

January is especially important for retirees and families because they’re more likely to become targets of fraud, scams, and other crimes.

Retirees often have:

  • Long addresses and employment histories
  • Stable credit profiles
  • Fewer active credit applications
  • Public retirement and property records

Families add another layer of risk:

  • Relatives are linked together in broker profiles
  • One exposed family member can expose others
  • Shared addresses and phone plans increase visibility

Scammers know this. That’s why households with established financial histories are prioritized early in the year.

Why quick fixes don’t work

Many people try to “start fresh” in January by:

Those steps help, but they don’t remove your data from broker databases. Credit monitoring services alert you after something goes wrong. Password changes don’t affect public profiles. And unsubscribing doesn’t stop data resale. If your personal information is still sitting in hundreds of databases, scammers can find you.

The January privacy reset that actually works

If you want fewer scam attempts for the rest of the year, the most effective step is removing your personal data at the source.

You can do this in one of two ways. You can submit removal requests yourself, or you can use a professional data removal service to handle the process for you.

Removing your data yourself

Manually removing your data means identifying dozens or even hundreds of data broker websites, finding their opt-out forms and submitting removal requests one by one. You also need to verify your identity, track responses and repeat the process whenever your information reappears.

This approach works, but it requires time, organization, and ongoing follow-up.

Using a data removal service

A data removal service handles this process on your behalf. These services typically:

  • Send legal data removal requests to large networks of data brokers
  • Monitor for reposted information and submit follow-up removals
  • Continue tracking your exposure throughout the year
  • Manage a process that most people cannot realistically maintain on their own

Because these services handle sensitive personal information, it is important to choose one that follows strict security standards and uses verified removal methods.

While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

Kurt’s key takeaways

Scammers don’t wait for mistakes. They wait for exposed data. January is when profiles are refreshed, lists are rebuilt, and targets are chosen for the year ahead. The longer your personal information stays online, the more complete-and dangerous-your digital profile becomes. The good news? You can stop the cycle. Removing your data now reduces scam attempts, protects your identity, and gives you a quieter, safer year ahead. If you’re going to make one privacy move this year, make it early-and make it count.

Xbox’s Towerborne is switching from a free-to-play game to a paid one

Xbox’s Towerborne is switching from a free-to-play game to a paid one

Towerborne, a side-scrolling action RPG published by Xbox Game Studios that has been available in early access, will officially launch on February 26th. But instead of launching as a free-to-play, always-on online game as originally planned, Towerborne is instead going to be a paid game that you can play offline.

“You will own the complete experience permanently, with offline play and online co-op,” Trisha Stouffer, CEO and president of Towerborne developer Stoic, says in an Xbox Wire blog post. “This change required deep structural rebuilding over the past year, transforming systems originally designed around constant connectivity. The result is a stronger, more accessible, and more player-friendly version of Towerborne — one we’re incredibly proud to bring to launch.”

“After listening to our community during Early Access and Game Preview, we learned players wanted a complete, polished experience without ongoing monetization mechanics,” according to an FAQ. “Moving to a premium model lets us deliver the full game upfront—no live-service grind, no pay-to-win systems—just the best version of Towerborne.”

With the popular live service games like Fortnite and Roblox getting harder to usurp, Towerborne’s switch to a premium, offline-playable experience could make it more enticing for players who don’t want to jump into another time-sucking forever game. It makes Towerborne more appealing to me, at least.

With the 1.0 release of the game, Towerborne will have a “complete” story, new bosses, and a “reworked” difficulty system. You’ll also be able to acquire all in-game cosmetics for free through gameplay, with “no more cosmetic purchasing.” Players who are already part of early access will still be able to play the game.

Towerborne will launch on February 26th on Xbox Series X / S, Xbox on PC, Game Pass, Steam, and PS5. The standard edition will cost $24.99, while the deluxe edition will cost $29.99.
