In 2014, astro teller, coordinator of the innovation laboratory at the Google, Google X, said in a lecture that the best technology is the one that becomes “invisible”. This invisibility is achieved when things become more practical to the , but we can stretch this definition and say that invisible technology is everyday technology, a kind of extension of our life. For a few years now, the wireless connection, with the popularization of mobile devices, has raised the much-loved Wi-Fi to that post.
However, technology alone is not enough, it is necessary to extract the maximum performance within the possibilities. The teacher Ikujiro Nonaka, says that in a world where the only certainty is uncertainty, the only sure source of competitive advantage is knowledge. This natural fight in the market, makes technologies we are familiar with constantly changing, and it is always a difficult (but necessary) task to keep up to date.
To strengthen your knowledge in networks Wi-Fi something so present in our lives, we've prepared some tips to make better use of the connection, security and management of your home network.
When should I upgrade my network? 4t4i5w
Our first tip starts with a classic question. Determining when a network upgrade is necessary is very important. The starting point is the router, it is the intermediary between your connection and the device that will receive the signal. Choosing a good router is the foundation of your network Wi-Fi access.
In addition to this control of the network, the acquisition of a large router, in of resources, creates more possibilities for the use of the network. Among these features, the main one is which protocol variant 802.11 he works. The most popular is still 802.11n, which works in the bandwidth 2,4 GHz But nowadays, considering the price reduction, it's worth getting one that is dual-band. So you will have a router that handles both 802.11n and 802.11ac, which es 5 GHz.
A router of this standard, called AC, guarantees a series of advantages over N. The main one is the reduction of interference and congestion caused by networks close to yours.
Rodrigo Paiva, product manager at D-Link, explains that today, billions of devices operate in the 2,4 GHz band and, as a result, cause a lot of interference with nearby ISM-type devices. In an effort to prevent this from happening, the 2,4GHz spectrum is divided into 11 “channels” (small bands). In theory, these channels provide three frequency bands, whose signals never overlap. Or to put it another way, three 2,4GHz devices using three different channels should never interfere with each other.
With dual-band routers, which in addition to 2,4 GHz also operate at 5 GHz, it is possible to use the higher frequency band to take advantage of additional channels that are less prone to interference than 2.4 GHz. And with the advantage of being able to create more than one wireless network using the same router. For example, network showmetech in the 2,4 GHz spectrum, and another point in the 5 GHz spectrum. This allows if your smartphone does not yet the 802.11ac protocol, you can continue using the network normally, with the access point via 2,4 GHz.
Felipe Apple, product coordinator at TP-Link explains that at 2.4 GHz the signal is able to reach farther than at 5 GHz. This is because of a basic characteristic of waves, which disperse much faster at higher frequencies. So, if your biggest concern is coverage, you should opt for 2.4GHz.
“Although the 5GHz frequency has a shorter range than the 2.4GHz frequency, it is capable of transmitting more data per second because it is virtually interference free. It is possible, for example, to have up to 20 nearby network devices operating on the same frequency without any loss of signal or internet speed.”, adds Appel.
Some models are even Tri-Band, and work in three bands: one at 2,4 GHz, and two at 5 GHz. But in this case, they are highly specific products, for a very select audience.
Other router features for you to keep an eye on! 60415
In addition to the issue of being able to handle more than one protocol, you should also note other special features when purchasing a new router:
Multi- Mimo (MU-MIMO): This technology improves the transmission efficiency of multiple connected devices at the same time, homes where multiple s access streaming services, for example, the MU-MIMO it is a way for the router to serve everyone universally, as it works by equally dividing the delivery of data to connected devices.
Unfortunately, this technology is only found in routers with very high prices in Brazil, such as the Archer AC5400 da TP link.
QoS (Quality of Service): In case you already share or are thinking about sharing your connection with someone, choosing a router with QoS can be a hand in the wheel, as you can set, for example, bandwidth limits, defining what is priority on the network. If you're crazy about online games, setting a higher bandwidth for this service will make it so that if a person opens a video it won't interfere with the game's transmission performance, as in the case of Ping, which is decisive.
Beamforming: Applied to some 802.11ac standard routers, this feature makes the router more condensed. Instead of maintaining the omnidirectional line, the router works to emphasize that the connected device receives the signal better. This technology has been explored for some time by many manufacturers, until the Google launched a router with beamforming, the OnHub.
In addition to the router, you can invest in other components to improve signal reception, or even expand this capacity. The most practical way is to purchase a powerline-based wireless repeater – it will be plugged into an outlet. Its installation and configuration is very simple and is a practical way to try to kill “blind spots” where the signal is not arriving.
Strengthen your security 2w734z
Security is currently a somewhat utopian topic, as much as we continue to apply and follow rules to improve this aspect, government agencies and companies often bomb the media with their gimmicks to snoop on the . But there's no way, guys, we can't abandon even the little privacy we have left.
Wireless networks with multiple connected devices are a full plate for cybercriminals, even more so with a huge wave of people who are unaware of simple parameters that must be applied.
Immediately change your router's default name and 4d6n6p
The first one is: change your router's default name and . Botnets are created with increasing force due to the army of “zombie devices” that basic security points are not enforced.
With the popularization of the internet of things, and more and more devices connected to the internet, it creates a mesh that if the cybercriminal infiltrates it can cause a lot of damage. Imagine a “smart” home, with several devices connected to the same router, which may be beautiful and full of fabulous features, but has been poorly configured in of security. When invading the network, it's not just the router that is held hostage, all other gadgets and, by the way, you and your family are too!
hide the SSID 43a1b
In the router settings it is possible to “hide the SSID (service set identifier), which is the name you assign to your network. With this, in addition to the , the smart guy who is thinking of breaking in will also have to know the name of a network not listed by default. I've had the opportunity to talk to some hackers and almost unanimously they say that when they see a network where the name is in the factory default way which basically is the brand name and the router they are the first potential targets. So, if you don't want to hide the network name, at least don't leave it the way it came from the factory.
Choose a good and use it in WPA2 mode 3a5p43
Essential point for your Wi-Fi network: don't leave it open, that is, choose a for it. But please don't follow the lazybones, using sequences like 1,2,3,4,5,6,7,8, abcdefg, among other weird sequences. Create a that is at least consistent.
According to National Institute of Standards and Technology In the USA, in fact, a longer turns out to be more efficient than one with the famous combination of uppercase, lowercase and special characters. On the router, when choosing the enforcement default, go from WPA2.
Use an antivirus 35i4u
This is a rule of thumb for home digital security in general. Although many people are rejecting antiviruses these days, they are still very effective, especially as manufacturers develop software with multiple layers of security in mind.
O Avast, for example, in its 2017 edition it has the feature “WiFi Checker, which scans all connected devices and the router itself, to detect problems. This feature is basically a “digital consultancy” for your wi-fi network. Very interesting resource!
Filter which MAC addresses can connect to the network 1k5e5k
Another important tip that can be performed within the router's own settings is to apply a MAC filter. O Media Access Control is the physical address of a component on the network. Your smartphone, your tablet, your Smart TV, among other devices have this kind of “chassis”, and it is possible to determine which ones can access the network.
One way to know the MAC address is with the app Advanced IP Scanner. Let's talk about it below.

Now let's move on to the management issue. In this regard, I want to indicate two apps for very specific and important functions:
The first one is the Advanced IP Scanner, which scans the network and quickly shows information about the devices that are connected. It is possible to have access to the IP address, MAC, among other details.
The second app is Wi-Fi Analyzer. when we commented above on the issue of interference caused by nearby networks also operating at 2,4 GHz? So, one way to change that, without having to buy a router based on 802.11ac (5 GHz), is to change the channel of the Wi-Fi network.
These channels are determined by the spectrum, and some of them are often used because of their proven efficiency: 1,6,11. Switching to a channel outside of this list is very effective for regions where you are surrounded by other hotspots.
This channel change can also be done in your router settings, based on the data the WiFi Analyzer provides you. The further away the channel you choose is from other networks, the better!
It is worth mentioning that routers based on 802.11ac, in addition to having fewer networks to create congestion, offer a greater number of available channels.
It is worth checking out this other article on our site that deals only with this issue of changing the channel of a wireless network:
Hopefully the tips listed here have been of some help to you. Don't waste any more time, and run to apply!
