Five things at home that wreak havoc on the wifi signal

Check out the five things you have inside your home that you didn't know are affecting the wifi signal.

There are often times when the wifi signal at home is quite weak and many do not know the reason why this is happening. In fact, many of us are forced to use our mobile data or lose patience by surfing with great difficulty and slow pace. Usually most of the problem comes from our internet provider or router settings. However, there are other factors that play a role in influencing the wifi signal.

1. Metal surfaces and furniture

Metal is a conductor, which virtually means it absorbs electricity. As your WiFi emits electromagnetic waves, any metal surface or object in your home will prevent the waves from spreading. If you want your Internet connection to work smoothly, you need to place the router away from the metal.

2. Brick or stone wall

There are some types of walls that can block the wifi signal Among the most common materials that block the connection are marble, cement, plaster and brick. That's why in two-storey houses, too, usually one floor doesn't have such good internet access. To fix it, place the router outdoors and away from the walls.

3. Mirrors

The material that allows us to see our reflection also reflects the signal released by the router. This object acts as a shield, making the Internet connection low.

4. Refrigerators and washing machines

As a general rule, electrical appliances that have tubes running in the water do not "do very well" with WiFi. Water can retain some of the energy from wireless waves, which negatively affects the quality of the internet connection.

5. Christmas lights

The colorful Christmas lights can also contribute to the poor quality of the Internet at home. The lamps have a chip means that generates a magnetic field that interacts with the router's electrical waves. In December, try to keep the router away from your Christmas tree.

Wi-Fi technology Closes in 20 Years: The Key Points

In an increasingly interconnected world, for many, the "coming" of WiFi technology was seen as a historic turning point in this story. Specifically, last Monday, September 30, was the 20th anniversary of the emergence of this technology during which people from all over the world have managed to reach out to their loved ones, work and so on. So, in a related document released by Cisco, a networking company, the key points of this 20-year WiFi journey are outlined.   Choosing the name  Reference to ALOHAnet could not be omitted from WiFi history. In 1971, the University of Hawaii built a network system that laid the foundations for the future development of wireless connectivity as we know it today. Today, we are all more or less dependent on it, but do we really know what its story is? When it comes to WiFi in essence, it is about IEEE 802.11, which is a standard protocol used to communicate with local wireless networks. Therefore, WiFi is the commercial "point" of this protocol, which was first introduced in 1997 and has a speed of about 2 Mbps.

For the future, in 2022, WiFi will become the main source of Internet access. Also in the same year, the average connection speed will reach 54.2 Mbps, as opposed to 24.4 in 2017.   1999: The WiFi debut in the market 1999 is the first year that WiFi made its debut on the market, thanks to the launch of 802.11b. Compared to its previous version, WiFi has now improved in speed and usability. The first devices that took advantage of this technology, such as laptops, were also released that year.    2004: WiFi is available on flights  The gradual deployment of this technology has persuaded many companies to use it for the benefit of their passengers since 2004. That year, wireless made its first appearance on the flight, allowing customers to use their personal computers to check in. e-mails them and do their jobs in general.

That year, wireless made its first appearance on the flight, allowing customers to use their personal computers to check in. e-mails them and do their jobs in general.

2009: The arrival of Wi-Fi 4 Four years later, specifically in 2009, the technology is moving to a new stage, namely WiFi 4, which promises users an even faster speed thanks to Mimo technology. The latter allows for even faster data transfer with Mbps reaching 450.   

2011-2012: millions of hotspots around the world  Between 2011 and 2012, WiFi is now well into the day-to-day lives of users. Now, there are millions of hotspots around the world, with about a quarter of families having this connection.   

2013: The arrival of 1 Gbps In 2013, the 802.11ac standard was introduced for the first time, enabling users to navigate at speeds of 1 Gbps. Indeed, according to a 2015 survey by IDC, wireless is the second thing that people could not live without. For the story, food tops the list with 30%.

2018: 13 billion devices are connected worldwide In 2018, the financial value of WiFi reached $ 2,000 billion. This increase is evident in terms of access to this technology. In fact, it is estimated that on average one person has two devices that allow him to access the Internet.   

2019: The appearance of WiFi 6 2019 will go down in history as the year of the introduction of WiFi 6, a technology based on the 5G network, reaching up to 5 Gbps. However, for this technology to be available on all devices available on the market, we will have to wait until 2020 for all devices to be compatible.   

2022: The average connection speed is increased even more As for the future, in 2022, according to a Cisco study, WiFi will become the main source of Internet access. 59% of people will actually use the wireless connection to navigate the web. Also the same year. the average connection speed will reach 54.2 Mbps, compared to 24.4 in 2017.   

Is WiFi Health Hazardous?  Are WiFi Networks Really Dangerous to Health? Although numerous investigations have been carried out in recent years, public debate on this issue is still open. In particular, in 2011, the IARC, the International Organization for Research on Cancer, labeled these networks as 2B, which may mean carcinogens. However, today there is no research to prove that there is a cause-and-effect relationship between the use of devices, such as smartphones and computers connected to WiFi, and the creation of tumors.
