Wi-Fi networks are a key part of millions of people’s lives worldwide. They are so important to us that it’s common to get to a hotel and the first thing we’re given – besides the keys, of course – is the Wi-Fi password. Thing is, there are tons of myths about Wi-Fi, so at Softonic we’ve made a list of four myths and facts about Wi-Fi networks.
Public Wi-Fi networks are unsafe
Myth or fact? Fact. Every time you connect to an open public Wi-Fi network, you have a high chance of getting your information intercepted by somebody. Remember that with this type of connection, data travels without encryption. That’s why it’s important you don’t connect to one without a password. Even if it has a password, our advice is that you try to stay away from them, barring exceptional circumstances.
We should note that when we use websites like Gmail or banking portals, their own certificates encrypt the content. But we urge you: stay away from them as much as possible. If you must use public Wi-Fi, be sure to use a VPN.
Wi-Fi networks are harmful
Myth or fact? Myth. This is one of the most widespread… and dangerous myths. We’ve heard over and over again that Wi-Fi networks can cause cancer, increase sexual dysfunction, etc. ALL of this is false.
It’s well verified that Wi-Fi networks aren’t dangerous. In fact, they’re well under the threshold set by the World Health Organization. After all, every day we receive hundreds of electromagnetic waves, both artificial (such as Wi-Fi networks) and natural (such as the planet’s electromagnetic field). Have no fear!
One Wi-Fi network can cause interference with another
Myth or fact? Fact. Though it usually doesn’t happen due to huge advances in technology, there’s a chance that your Wi-Fi network can interfere with your neighbor’s. This usually happens where there are dozens of Wi-Fi connections in a small area. It’s likely that one is intruding on your frequency and giving you problems. But there’s a solution.
If you notice this happening, our advice is that you restart your router so the connection doesn’t suffer interference. Likewise, you can add a password if you haven’t already. Never leave your Wi-Fi network unprotected.
Walls can affect Wi-Fi connection
Myth or fact? Fact. Electromagnetic waves from Wi-Fi can go through walls, of course, but their quality can be affected depending on several variables. That’s why experts advise that the router is always placed in a central location of the home, since the distribution of waves will be better.
On the other hand, we should talk about those other “variables” we mentioned earlier. It depends if you have a wall with tiles, mirrors or metals. Each kind of material affects Wi-Fi waves, not to mention any obstacles along the way.
