Most people probably don’t even notice the actual speed of their internet connection. If it ‘goes fast’, they’re happy.
What many folks don’t realize is that they may be wasting a large chunk of their very high speed net connection.
If you use even newer flavors of WiFi, chances are you aren’t taking full advantage of the connection you’re paying for! Heck, even with Ethernet, your download speeds may be lower than you think.
So, how do you tell?

Microwave ovens that you use to cook food operate at a frequency of 2.45 GHz.
This is the same radio band where one finds WiFi, Bluetooth, and so on.
So, why is everything lumped into this one chunk of the frequency spectrum? Is there something particularly magical about 2.4 GHz?
It turns out that there is a common misconception about this frequency and water.
The truth, however, is far more mundane…

First of all, it’s finally happened: 2.5 Gbps Ethernet is HERE!
It’s already rolling out, and consumer-grade 2.5 gig switches will arrive shortly.
The other big news is the unveiling of WiFi 6E.
A new flavor of WiFi 6, the 6E variant adds the 6GHz radio band and speeds of up to 11Gbps… Or so they say.
So, the question is: stick with wired, or go WiFi 6E wireless? Which is faster?

In this episode, I answer some questions and comments left on my various 5G videos – especially 5G is just the tip of the iceberg.
Since I posted that video 2 years ago, it has received almost 6000 comments. Many are informative, supportive, and heartening.
And then there are the “other” comments…
Join me for a deep dive QnA – and a bit of fun!

Given the current global situation with the virus lock down, we are all looking for answers.
Some people have suggested that 5G systems are causing the symptoms of Covid-19. But does that really fit the data?
It turns out that we can easily find several rather large holes in this theory from easily available data online.
Of course, that does not mean 5G is the greatest thing since sliced bread!
But it does mean that in the current climate, we should strive to give credit where it is due, and also place blame where it belongs.

There’s a new flavor of Wi-Fi in town: Wi-Fi 6!
In case you’re confused, I’m talking about IEEE 802.11ax, the successor to 802.11ac (which is now called Wi-Fi 5).
Are you confused yet?
While I’m not a terribly big fan of wireless stuff, Wi-Fi 6 does include several improvements that increase capacity and speed for more connected users.
The question is: does Wi-Fi 6 go far enough, or is wired still better?

So you’ve read all the studies about our Wireless Wonderland, and you’d like to go wired.
But where to even start?
It turns out that wiring up your house or apartment with ethernet cables and switches is WAAAAY easier than most people think.
It’s literally a plug-n-play kind of thing.
There are a few things to keep in mind though before purchasing gigabit ethernet switches and Cat 7 ethernet cable…

It seems there are some common misconceptions out there about what 5G actually is and how it will work.
I wasn’t planning on another 5G video, but alas…
Much of this confusion is totally understandable since info is hard to come by despite the fact that 5G and IoT is the talk of the town!
Near the end I also toss in a few recent news stories related to troubles that 5G is causing or will cause.
You’d think they’d check this stuff out first BEFORE spending all that money… But then you remember that this is Planet Earth in 2019.

Many people have asked me about the Q-Link and other similar gizmos.
You’re supposed to simply wear them, and they strengthen your body via “resonance” such that you are even protected from the negative effects of all kinds of EMF.
Well, I used to think that was nuts… Until my doctor friend said she loves hers!
So, I decided to take another look. It had been almost 20 years since I first decided they were just snake oil. Plus, I suppose with age comes the knowledge that we’re not always as smart as we think we are.
It turns out that the result of using these things is actually rather interesting…

These days, WiFi is everywhere. Even your washing machine probably has it. 😉
I typically don’t recommend using WiFi due to the huge amount of evidence indicating that it’s probably not the best thing for your health.
But there’s another reason to go back to cables…
WiFi is quite often WAAAY slower than most people think. In fact, it’s very rare that you will get anywhere near the maximum speeds advertised when you buy a WiFi access point or router.
What to do, what to do?
