Remember When “Wireless” Meant a Really Long Cord?

Remember that? When you first heard the word “wireless,” you probably thought someone had finally invented a telephone without that annoying coiled cord that tangled around your neck. Well, here’s the thing about WiFi – it’s actually more wireless than any of that. It’s invisible signals floating through your home, letting you watch your grandchildren’s soccer game videos from your living room without running cables under the carpet.

Think about it: you’ve already navigated dial-up modems that screamed like angry robots. You’ve dealt with Ethernet cables snaking around your house like technological serpents. You’ve figured out email, online banking, and probably at least three generations of smartphones. WiFi? That’s just the next logical step in your ongoing tech success story.

Let me explain what it actually does, and I promise I won’t bore you with unnecessary jargon.

The Journey From “That Awful Modem Sound” to Today

You remember that sound, don’t you? That horrible electronic shrieking when your computer was trying to connect to the internet through your phone line? Eeeeerrrrrrrrrrrrrhhhhhhhhh. If you remember that, you’re already qualified to understand why WiFi is such a big deal.

Before WiFi came along, your options were pretty limited. Dial-up was slow – painfully slow. Downloading a single image could take what felt like forever. Then came Ethernet cables, those bulky things that looked like they belonged in a telephone switchboard. They were faster, sure, but now you were tethered to one spot. Want to check your email from the kitchen? Too bad. You had to go back to your desk.

WiFi changed all that. Suddenly, you could take your laptop anywhere in your house. You could sit in your favorite chair. You could work from the porch on a nice day. It was freedom, pure and simple.

The Evolution: From “That’s Impressive?” to Today’s Speedster

Here’s something that fascinates me about technology: each upgrade always seemed impossible until the next one came along. When WiFi 802.11b arrived in 1999 with speeds of 11 Mbps, people thought it was incredible. Today, that’s slower than a bicycle in rush hour traffic.

Let me walk you through how WiFi has evolved. Think of it like the difference between driving a horse and buggy versus a modern sedan:

IEEE 802.11 (1997) – The original. 2 Mbps. Cutting edge at the time, though barely.

802.11b (1999) – Five times faster. 11 Mbps. Now we’re talking. This was like upgrading from a horse to a bicycle.

802.11g (2003) – Jumped to 54 Mbps. This was the sweet spot for a lot of people – fast enough for most things, good range around the house. Like trading that bicycle for a reliable sedan.

802.11n (2009) – Here’s where things got interesting. 600 Mbps, and it got smart about handling multiple devices at once. MIMO technology – that’s “Multiple Input Multiple Output” if you want to impress your grandkids – meant your WiFi actually got better when multiple people were using it instead of worse. Like a bus that somehow runs faster when it’s full.

802.11ac (2013) – We’re talking 1.3 Gigabits per second now. That’s not just faster; that’s a sports car. You could stream HD video on multiple devices without anyone complaining about buffering.

WiFi 6 (802.11ax) (2019) – Today’s standard. Up to 9.6 Gbps and specifically designed for homes absolutely packed with devices. Your smartphone, your tablet, your smartwatch, your TV, your doorbell… all hungry for bandwidth. WiFi 6 handles it with ease.

Each generation was designed to solve a problem that the previous one couldn’t quite handle. That’s how technology actually works, despite what the marketing folks try to tell you.

How It Actually Works: No Magic, Just Smart Radio

Here’s the truth: WiFi isn’t magic. It’s just radio waves, much like the AM/FM radio in your car. Think of it that way and suddenly it makes a lot more sense.

Your router – that little box that probably sits in your closet or living room – is basically a radio station. Except instead of broadcasting music, it’s broadcasting internet signals. Here’s how the process works, and I’m going to keep it simple because simple is better than impressive:

Step 1: Your Router Says “Hello”
Your router is connected to the internet via a cable (usually fiber, cable, or DSL – the same technology your neighbors probably use). Once it’s plugged in and turned on, it starts broadcasting radio waves in all directions. These waves spread throughout your home. That’s literally it.

Step 2: Your Device Listens
When you turn on your phone, tablet, or laptop, it looks for available WiFi networks. It’s like your device is tuning a radio dial, searching for stations. On your screen, you see a list of available networks – your own home network, maybe the neighbor’s network, possibly that café WiFi you used last week.

Step 3: You Make the Connection
You select your network (hopefully your own), enter your password, and boom – connected. Your device is now in conversation with your router, and through your router, with the whole internet.

Step 4: Information Flows Both Ways
Now you can load websites, stream videos, send emails. It’s a two-way conversation: you request something (“Show me the weather in Portland”), and the internet sends it back. Just like a telephone call, except instead of voices, it’s data.

So What’s Coming Next? WiFi 7 and Beyond

The tech industry never rests, does it? Even as we’re getting comfortable with WiFi 6, the engineers are already working on WiFi 7. They’re promising speeds up to 40 Gbps – that’s ridiculous, but in the best possible way. Ultra-high-definition video streaming. Video calls with zero lag. Multiple people in your house all doing bandwidth-intensive things simultaneously without anyone noticing.

Will you need it? Probably not yet. Does it sound nice? Absolutely.

The Security Part – Because Leaving Your Door Unlocked Is a Bad Idea

Now, here’s where I need to get a bit serious with you, because this is important: your WiFi network is a door into your home. You wouldn’t leave your front door unlocked, and you shouldn’t leave your WiFi network unprotected either.

Your First Line of Defense: A Strong Password

When you set up your WiFi, create a password that’s actually strong. I know, I know – you probably have “WiFi123” or “MyPassword” or something your grandkid came up with. Time to fix that.

A strong password looks something like: “BlueCar#Kitchen2024Jazz” – it has uppercase letters, lowercase letters, numbers, and symbols. It’s personal enough that you can remember it, but random enough that a hacker using a computer couldn’t guess it in any reasonable amount of time.

Change it occasionally. Every few months is reasonable. And for goodness sake, don’t write it on a sticky note on your router. Yes, people actually do this.

The Hidden Danger: Public WiFi

Here’s something I need you to understand: free WiFi in coffee shops, libraries, and airports? It’s convenient, sure. It’s also like leaving your front door wide open. Anyone on that same network – and I mean anyone – could potentially see the information you’re sending and receiving.

This is where a VPN comes in. VPN stands for “Virtual Private Network,” and think of it like this: imagine sending a letter sealed in a locked box, and only the person who receives it can open it. That’s what a VPN does. It encrypts your internet connection, creates a secure tunnel for all your data, and makes it extremely difficult for anyone to see what you’re doing online.

For seniors especially, I’d recommend using a VPN whenever you’re on public WiFi. There are good ones out there – some are free, some are inexpensive. Use one. Your personal information is worth protecting.

I did a whole blog on VPNS, so if you are interested have a look at:

The Bottom Line: You’ve Got This

Remember when you thought you’d never figure out email? Or online banking? Or video calls? You did all those things. You adapted. You learned. You’re still here, still connected, still growing.

WiFi is just another tool. It’s not magic, it’s not as complicated as it sounds, and most importantly, it’s not something to be afraid of. It’s something to understand so you can use it to stay connected with your family, explore your interests, and engage with a world that’s increasingly digital.

You’ve mastered rotary phones becoming smartphones. You’ve gone from encyclopedia lookups to Google searches in seconds. You’ve navigated dial-up modems becoming broadband. This? This is just the next chapter in your ongoing tech success story.

So here’s my challenge to you: take a moment and actually understand how your WiFi works. Look at your router. Figure out your password. Test your connection from different rooms. Maybe even talk to someone at your local Best Buy or library if you have questions. Because knowledge is power – it’s the difference between being intimidated by technology and being empowered by it.

And that’s the difference that matters.
