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 If your Wi-Fi is protected by a weak password or uses outdated encryption, a skilled attacker might gain access without ever stepping inside your house.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.

The future of local TV news has taken a Trumpian turn

The future of local TV news has taken a Trumpian turn

This is The Stepback, a weekly newsletter breaking down one essential story from the tech world. For more stories on Big Tech versus politics in Washington, DC, follow Tina Nguyen and read Regulator. The Stepback arrives in our subscribers’ inboxes at 8AM ET. Opt in for The Stepback here.

A long time ago, in 2004, the Federal Communications Commission laid down a rule designed to prevent a monopoly: No one company could broadcast to more than 39 percent of all the TV households in the United States. But then Donald Trump returned to the White House in 2025. Brendan Carr became FCC chairman and immediately kicked off a deregulatory initiative called “Delete, Delete, Delete,” in which Carr vowed to get rid of “every rule, regulation, or guidance document” that placed “unnecessary regulatory burdens” on companies. And within months, Nexstar, which already owned over 200 stations nationwide and had hit its ownership cap, announced that it had entered an agreement to purchase its rival, Tegna, for an estimated $6.2 billion — something that could only happen, however, if Carr agreed to change the FCC’s rules.

If you ask Nexstar why it’s pursuing a merger that would give it control of over 80 percent of the market, it’d point to Big Tech as the culprit. As advertisers take their money to Netflix, YouTube, and other digital streamers, linear television — the local television news, the broadcast affiliates, the basic cable networks — has suffered, forcing them to consolidate and shut down newsrooms. In that sense, Nexstar argued, the merger would help it compete for ad revenue with the streaming services, thereby building more robust local journalism. However, the merger’s opponents believe that this is a basic violation of antitrust laws and principles — not to mention the danger of letting one company have editorial control over the vast majority of America’s local television newsrooms.

But the second Trump administration handles regulatory hurdles a little differently than others, and companies have found that it’s faster to get what they want if they bypass the agencies and talk (read: suck up) to Trump directly. And when Nexstar did so publicly, it confirmed its opponents’ fears about political influence. Last September, in the fraught weeks after the fatal shooting of Charlie Kirk, Nexstar announced it would no longer broadcast Jimmy Kimmel Live! — a response to Carr’s claim that the FCC could revoke the broadcast licenses of TV stations that aired the comedian’s comments related to Kirk. It briefly led to ABC suspending Kimmel’s show, though ABC and Nexstar soon reversed their decision after a massive nationwide backlash and an ABC boycott.

However, Nexstar’s loyalty to Trump himself was not enough to win over his most powerful MAGA supporters. Newsmax, a cable news network with a deeply pro-Trump bent, and its CEO, longtime Trump donor and outside adviser Chris Ruddy, filed a lawsuit objecting to the merger, claiming that Nexstar’s anticompetitive behavior would force channels like his off the air with steeper carriage fees. He specifically accused Nexstar of jacking up the fees for stations to carry Newsmax, while offering its similar network, NewsNation, for much cheaper.

The Nexstar-Tegna MAGA makeover then took a more subtle turn. NewsNation hired the pro-Trump Fox News commentator Katie Pavlich and gave her her own primetime show. (The network had already hired a slew of former Fox journalists as well.) Around this time, a political group called Keep News Local began airing ads in DC that seemed to directly address Trump, praising him for having “defeated the fake news monopolies before through independent voices and local news” and claiming that the Nexstar-Tegna merger was “crucial for MAGA to survive.” (A little self-contradictory and mildly illogical, but it’s the kind of stuff that Trump likes to hear.) When I last spoke to Ruddy in February, I asked if he’d worried that the dark money going into Keep News Local would sway Trump, and he chose his words carefully: “I think at the end of the day, Trump makes up his own mind. I’m not sure he’s going to be influenced by an ad campaign.”

For months, no one could accurately predict if Trump would override Carr’s wishes and bless the deal, as he’s often done for other companies facing regulatory scrutiny. Trump’s Truth Social posts about the merger have been a good indicator of how precarious the merger has been and who’s been able to influence him at any given moment: Last November, he blasted the deal as an “EXPANSION OF THE FAKE NEWS NETWORKS,” but by February, he posted that the deal would “help knock out the Fake News because there will be more competition.”

Several current and former NewsNation employees told Status at the time that they feared that the parent company was steering NewsNation away from the centrist, “unbiased” reputation they’d long cultivated. “A lot of people within the network believe that the network has gone hard right to appeal to Trump and Brendan Carr,” one former employee told Status. Coincidentally, days before the deal was finalized, NewsNation began ramping up its explicitly pro-Trump content, tweeting a clip of CNN’s Kaitlan Collins being berated by White House press secretary Karoline Leavitt, along with the comment “Just going to leave this here.”

When Trump greenlit the merger in mid-March, but before the FCC’s three commissioners could vote on whether to waive the ownership cap, Nexstar and Tegna immediately announced a new complication: Tegna and Nexstar had already started merging. Tegna was no more and CEO Mike Steib had already sold $22.6 million of his company stock.

In response, eight state attorneys general and satellite TV operator DirectTV, which had already been planning to file separate federal antitrust suits against the merger, asked US District Judge Troy Nunley in Sacramento for an emergency restraining order that would prevent Nexstar from taking over Tegna’s assets. The order was granted on March 27th and on April 17, Nunley issued a formal injunction, ruling that Tegna must be operated as an independent financial entity, and Nexstar must take steps to ensure it remains separate from Tegna before further legal proceedings.

For now, Nunley has allowed the states and DirecTV to combine their cases, in which both argue that the merger was a clear violation of antitrust laws and would crush news competition.

Meanwhile, Republicans and Democrats in Congress are furious at Carr. On March 30th, Sens. Ted Cruz (R-TX) and Maria Cantwell (D-WA) sent the chairman a joint letter admonishing him for allowing his staff to waive the regulations to let the merger pass, instead of having the full commission of political appointees — one from the Biden administration — vote on it. “Under these circumstances,” they wrote, “any subsequent vote risks being largely procedural rather than a genuine exercise of commission responsibility.” They also pointed out that their hasty approval without the commission’s approval would now complicate the merger financially: “In a transaction of this scale, where integration proceeds quickly and unwinding becomes impractical, delay in judicial review can insulate the decision from meaningful challenge.” Notably, though they share similar ideological views on the media and deregulation, Cruz and Carr have frequently clashed over how to achieve their objectives. Cruz previously slammed Carr as a “mafioso,” for instance, for the way he’d used the FCC to silence Kimmel.

But even if it’s legally paused, the journalistic merger’s fallout has started to hit local news. NPR’s David Folkenfirk reported on Tuesday that Tegna journalists had already started receiving orders to stop broadcasting content from major broadcasters like ABC, CBS, and NBC — media outlets being targeted by Carr — and instead begin airing content from Nexstar’s NewsNation.

  • Brendan Carr’s views on using the FCC to punish major broadcasters was outlined pretty extensively in the chapter he authored in Project 2025, an initiative led by the conservative Heritage Foundation on how to reform the federal bureaucracy to be more favorable to the American right.
  • Exactly how much is local television losing to digital? According to industry publication NewscastStudio, in an investor call defending the purchase, Nexstar chairman Perry Sook cited a market research study from Borrell Associates, which found that “digital advertising in local markets exceeds $100 billion, compared to just $25 billion for local linear television advertising, with nearly two-thirds of digital ad dollars flowing to five major technology companies.”

Chinese robot breaks human world record in Beijing half-marathon

NEWYou can now listen to Fox News articles!

A Chinese-built humanoid robot beat the human half-marathon world record in Beijing on Sunday, marking a breakthrough moment in a high-stakes global race for technological dominance.

A robot developed by Chinese smartphone maker Honor completed the 21-kilometer (13-mile) race in 50 minutes and 26 seconds, beating the human record of about 57 minutes set by Uganda’s Jacob Kiplimo last month.

The performance marked a dramatic improvement from last year’s inaugural event, when the top robot finished in more than 2 hours and 40 minutes.

Dozens of humanoid robots competed alongside about 12,000 human runners, navigating a parallel course to avoid collisions.

The RAM shortage could last years

The RAM shortage could last years

According to Nikkei Asia, even as suppliers ramp up DRAM production, manufacturers are only expected to meet 60 percent of demand by the end of 2027. SK Group chairman has even said that shortages could last until 2030.

The world’s largest memory makers — Samsung, SK Hynix, and Micron — are all working to add new fabrication capacity, but almost none of it will be online until at least 2027, if not 2028. SK opened a fab in Cheongju in February, but that is the only increase in production among the three for 2026.

Nikkei says that production would need to increase by 12 percent a year in 2026 and 2027 to meet demand. But according to Counterpoint Research, an increase of only 7.5 percent is planned.

The new facilities will primarily focus on producing high-bandwidth memory (HBM), which is used in AI data centers. With the companies already prioritizing HBM over general-purpose DRAM used in computers and phones, it’s not clear how much these new fabs will help alleviate the price crunch facing consumer electronics. Everything from phones and laptops, to VR headsets and gaming handhelds have seen price increases due to the RAM shortage.
