I think this is pretty much common sense, it’s like the difference between driving a Ferrari vs driving a Volkswagen Beetle. Ethernet of course came in line before wireless. The truth is, the first Ethernet cable was introduced in 1973, in the image below you will see it. Bob Metcalfe had sent an internal memo to his colleagues at Xerox with a proposition of a using a local system of workstations that would interact with each other, along with files, and printers. All of the devices would all be linked together by just one coaxial cable, he had said at the time, and it would run within a local area network, conveniently at that time.
At the time he called it an Ether Network, or in other words, as we call it now, Ethernet. And then by 1976 there were then just over 100 devices linked into Metcalfe’s own local network, and then it was even used to test the globe’s first ever laser printer which was then being created concurrently in a different research facility within Xerox themselves. Metcalfe had an assistant named David Boggs, who had published their own discovery within the Association for Computing Machinery just later this current year. Of course, the rest is history.
This image shows a sketch that Metcalfe had sketched in his original memo to all his colleagues:
Now let’s look at the difference in speed of Ethernet versus Wireless
- A standard ethernet cable goes up to 100MB’s/second without any interruptions.
- Wireless, can go up to 300MB’s/second, but is limited to it’s signal strength. Most often, Ethernet is only faster because your directly connected to the internet modem where with Wireless you have to be very close to the Wireless modem to get the fastest speeds. Wireless also comes in different types, as you may have heard of “802.11a, 802.11b, 802.11g, or 802.11n”, which all come in different speeds.
Setting up Wi-Fi
If you ever set up a Wireless internet connection, try to have the modem upstairs as well. The signal can be picked up more easily when you are either level with the modem in the upstairs area or in the downstairs area of your house. It’s like gravity can more easily carry an internet connection downwards, versus upwards, which takes more work for the modem to provide a signal to your device.
Setting up Ethernet
I guess I can say that most modems that you get with any ISP (Internet Service Provider) come as a Wireless internet supported modem. Sometimes you can buy a stand alone modem that supports that ISP, so you can then connect that modem to a Wireless Router of your own so you can customize it more.
Anyways, if you have a modem that is wireless, or a modem connected to a router, just connecting your computer through Ethernet to that modem is good enough, don’t worry about connecting the ethernet cord directly to the modem.
Why is Ethernet more secure?
It’s because an Ethernet connection is only accessible from the modem itself. A wireless modem or router can be accessed anywhere that a device is in range of picking up a signal. So for someone to hack into your “wired” network, they would have to break into your house. Where a hacker sitting in their car outside your house or two houses down could pick the signal up and decrypt the wireless password.
Unfortunately most people these days have both a wired and wireless internet connection or I should say “network”, so you just have to set your wireless to WPA2 and you got to create a really long and complicated password. Another way to make your wireless internet network more secure is to disable “SSID Broadcasting”, this way you have to type in your network SSID name and then the password manually to connect in the first place, where normally if your wireless network was already broadcasting it’s SSID name, say you named your network “poodles”, you would just click on it and then type in the password and go from there.
Manually connecting is called creating a “Wireless Network Profile”. All you do is, in Windows you go to “Manage Wireless Networks” and then click on “Add”, and then you type in the wireless network details from there.
My own setup
So, in my own setup, I always am connected through Ethernet to my main desktop computer. I use Wireless for my iPhone and my Laptop, just because it’s easier to use wireless, and I really have no choice but to use wireless with my iPhone anyways.
