The biggest Wi-Fi mistake you didn’t know you were making

You’ve got dinner in the oven, you’re looking for extra glasses, and your cousin’s kid screams (again), “What’s the Wi-Fi password?” You’re juggling a hundred things at once, and the last thing you want to do is to spell out your password.

Here’s the good news: You can slap a printout on the fridge, and everyone can scan it with their phones to connect. But first, I’ll show you how to create a separate network so you don’t need to worry about little Billy getting into your personal stuff on your devices and computers.

SCAMMERS ARE TARGETING TEENS WITH THESE NASTY TRICKS

When guests connect to your main Wi-Fi, they can potentially access devices like smart TVs, printers, and even your laptop or phone if file sharing is enabled. Worse, if their device is compromised, your whole network could be at risk. A guest network keeps everyone happy while keeping your private life private.

Most modern routers let you set up a guest network without having to be a tech guru. Warning: This will take you a few minutes, but it’s totally doable.

RELATED: Is your internet slo-o-o-w? Let’s fix that.

Step 1: Log into your router’s admin console. You’ll need your IP address. You can usually find this on a sticker on the bottom or side of your router. Seeing 192.168.1.1 or 192.168.0.1 is common.

If you don’t see yours …

  • On Windows: Open the Start menu, search for “Command Prompt” and, with your Command Prompt open, type in ipconfig and press Enter. Look for the line that says “Default Gateway.” This is your router’s IP address.
  • On Mac: Go to System Settings > Network. Select your Wi-Fi network > Advanced. Your router’s IP address is under Router.

Step 2: Open your browser, type http:// and paste in your IP address. Hit Enter to open a login page. For the credentials, try the username admin and the word password for the password. If the defaults are different, they’re likely printed on your router. You can also check this site that lists default passwords for almost every router in use.

Step 3: Look for a setting called Guest Network or Guest Wi-Fi. Give it a different name (aka SSID) than your main network, along with a strong, unique password.

TECH TIP: SAVE YOUR MEMORIES BEFORE IT’S TOO LATE

If you have snoops in the family … When family and friends connect to your Wi-Fi guest network, you can block them from accessing your files or devices on your primary network. Turn off the local access setting.

Sorry, but dedicated snoops won’t stop at one closed door. Here’s a sign someone is poking around.

While you’re at it, a quick security check

Before you finish, take these extra steps to lock things down:

BIOMETRIC DATA: IS IT SAFE TO HAND IT OVER TO ANY COMPANY THAT ASKS?

  • Change your admin password: If your router still uses the default login, update it.
  • Update your firmware, too: Check for software updates to keep your router secure from vulnerabilities.

Your network is a bigger target than you realize.

Now for the fun part

Girl squinting screen

Create a QR code that automatically connects guests to your new guest network — no hassle, no drama. With the free site QIFI.org, all you need is three pieces of info:

  1. SSID: This is your Wi-Fi network name. Find it on the back of your modem, in the admin console or on your network app.
  2. Encryption type: Choose WPA/WPA2/WPA3. You can find this in your phone’s Wi-Fi section under the network details.
  3. Key: This is your router password. It’s on the back of your router if you’ve never changed it. (Please tell me you’ve changed it!)

Hit Generate and your QR code is ready. Print some copies of it to hang around the house, or do what I did: Order this custom sign that looks classy. Now, when someone asks for the Wi-Fi password, you can just point.

Stranger Things 5’s first trailer promises an epic showdown

Stranger Things 5’s first trailer promises an epic showdown

It’s been a long time coming, but we finally have a real look at the end of Stranger Things. Netflix just released the first teaser trailer for the show’s fifth season, which will also be its last when it starts streaming later this year. As was alluded to in the finale of season 4, the new trailer — which, despite being called a teaser, clocks in at nearly three minutes long — is focused on the major showdown with Vecna that will presumably end the string of supernatural bad luck in Hawkins, Indiana for good.

Here’s the official setup for the finale, according to Netflix:

The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished — his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming — and with it, a darkness more powerful and more deadly than anything they’ve faced before. To end this nightmare, they’ll need everyone — the full party — standing together, one last time.

Landline identity theft leads to major bank fraud

NEWYou can now listen to Fox News articles!

Landline identity theft is an emerging threat that gives scammers backdoor access to your accounts.

IS YOUR PHONE HACKED? HOW TO TELL AND WHAT TO DO

How forgotten landline identity theft drained a bank account

Richard from Reno, Nevada, shared a troubling story. His friend lost money to scammers because their old landline number was still linked to a bank account.

It started with a credit alert asking whether the friend had opened a new card. They said no and thought the issue was resolved.

But soon after, they couldn’t access their bank or investment accounts. Despite having transaction alerts enabled, the money was already gone.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

The scammer didn’t hack a password. Instead, they used a security loophole, an outdated landline still listed on file.

“My friend had an old but active landline linked to their bank account,” Richard said. “The thief convinced the phone company to port the number to a mobile device. Then they used it to intercept security codes and drain the account.”

The scammer requested a password reset. The bank sent a verification code to the old number, now controlled by the scammer. That code let them change the login, lock the victim out, and move the funds.

Credit monitoring caught the new credit inquiry but failed to detect the fraud inside the existing accounts. By the time access was restored, the money had disappeared.

Why landline identity theft is so easy to pull off

This scam highlights how identity thieves evolve. They don’t always need advanced tools. Sometimes, they just use the details you’ve forgotten.

The role of number porting

The attacker used number porting, a process meant to help people keep their number when switching carriers. It’s legitimate, until scammers exploit it.

In this case, the thief pretended to be the victim and asked the phone company to transfer the landline number to a mobile device. Once the number was active, they received calls and texts, including two-factor authentication (2FA) codes.

How old contact info creates new risks

Many people forget to update recovery settings after creating an account. But an outdated phone number or email can still receive security codes. If a scammer gains control of those recovery tools, your accounts are wide open.

The overlooked weaknesses that made this attack work

Even small gaps in your security settings can lead to big problems. These were the key vulnerabilities in this case:

Old phone numbers stay linked too long

Scammers can hijack even inactive numbers through porting. If those numbers still connect to your bank or email, they become an easy target.

Credit monitoring can miss real-time fraud

Tools that monitor new credit accounts won’t always detect unauthorized transactions in your existing bank or investment accounts.

Weak 2FA setups can be hijacked

2FA is helpful, but only when the linked phone number or email is secure. If a scammer controls that method, they can bypass your protections.

How to prevent landline identity theft

You can’t stop scammers from trying, but you can make it much harder for them to succeed. Use these steps to reduce your risk.

1. Audit your account recovery options: Check your recovery settings on every important account. Delete old phone numbers or backup emails. Keep only active, secure options on file.

2. Use an authenticator app: Authenticator apps like Google Authenticator, Authy, or Microsoft Authenticator generate one-time login codes on your device. This is safer than relying on text messages, which scammers can intercept.

3. Freeze number porting with your carrier: Contact your phone provider and ask about port-out protection. This feature blocks scammers from transferring your number without extra identity verification like a PIN or in-person request.

4. Remove your info from data broker sites: Scammers gather personal details like old numbers from public broker listings. Use a data removal service to erase this info from the web.

5. Monitor your bank activity directly: Set up alerts through your bank for every transaction. Log in regularly, even if you haven’t received any warnings, to catch fraud faster.

6. Use a password manager: A strong, unique password protects each account. A tool like a password manager creates and stores complex passwords for you. It also tracks password health and alerts you to possible breaches. Get more details about my best expert-reviewed Password Managers of 2025 at Cyberguy.com/Passwords.

7. Consider full identity theft protection: Even with strong passwords and 2FA, your personal info can still be exposed. An identity theft protection service offers dark web monitoring, account alerts, and some offer up to $1 million in identity theft insurance. See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com/IdentityTheft.

Kurt’s key takeaways

Landline identity theft shows that forgotten account settings can turn into serious threats. Take a few minutes to review your recovery options. Switch to authenticator apps. Set up port-out protection. And don’t rely on credit monitoring alone, it can’t catch everything. These simple steps can help you stay ahead of evolving scams and protect your most important accounts.

Analogue’s 4K N64 has been delayed again, but only by a month

The Analogue 3D has been hit with another delay, but should still be launching this summer. In an update on its preorder website, Analogue explained that it’s modern take on the Nintendo 64 “is now shipping in late August 2025,” after previously aiming for July. The company said in a separate statement that the decision was made due to the ever-changing situation around US tariffs.

“Following last week’s sudden tariff changes, Analogue 3D will now begin shipping next month,” the company explained in a post on X. “We’re absorbing the costs — your preorder price stays the same. No additional charges. Late August, the wait ends: reviews go live with everything we’ve been saving for this moment.”

Like its previous hardware, the $249.99 Analogue 3D is a modern console designed to play old games, in this case N64 cartridges. The new console can upscale classic games to 4K and includes multiple display modes to mimic the look and feel of a CRT display, and the company says that it supports 100 percent of N64 cartridges. It was originally planned for a launch in 2024, but has been hit with multiple delays since it was initially announced.
