How to optimize your Wi-Fi connection
What is a modem and Wi-Fi router
The modem is the device provided by the internet provider. Its function is to bring the information that is on the web.
The Wi-Fi router is the device that takes this information from the modem and distributes it.
Currently, most internet providers deliver a 2 in 1 device called internet box which includes Wi-Fi modem and router combined.
The Wi-Fi signal is propagated from your internet box on the radio bands. Each band is a channel for the propagation of information. However, the use of the internet has seen a huge explosion and new connected devices are consuming large amounts of it. For this reason, manufacturers have expanded their ranges by providing one-band, two-band or dual band and even three-band Wi-Fi routers. All of them use the two 2.4 Ghz and 5 Ghz channels.
On the other hand, Wi-Fi standards are constantly improving. This is how the latest Wi-Fi ac standard has a speed that exceeds Gigabit/s. This standard has recently seen an improvement. It is now accompanied by MU-MIMO functionality (Multi-user with multiple inputs and outputs).
These selection criteria are only to be considered when buying a better quality router:
- Router speed: The correspondence of standards to speeds is as follows:
. 802.11n bit rate around 450 Mbits/s,
. 802.11ac speed around 1300 Mbits/s on 5 Ghz,
. 802.11ac with MU-MIMO broadband of around 1700 Mbits/s.
- Antennas: Routers that have external antennas deliver more powerful signal strength and allow comfortable Wi-Fi access. These antennas are generally directional and adjustable to obtain the best possible range.
- Ethernet ports: To obtain the optimal speed offered by the Internet provider, there is no better than using Ethernet ports.
Definition of an access point
The Wi-Fi access point is a device that creates a wireless local area network or WLAN. It is any terminal used supplied with LAN to broadcast the Wi-Fi signal received from a router, switch or hub by wired link (Ethernet cable). This signal can come directly from your adsl box through its Ethernet port.
The access point is the recommended device and the most suitable for businesses because it can manage more than 60 connections at the same time.
Connecting the access points a little everywhere, everyone can move between offices and within the factory without any risk of losing the connection.
The devices used automatically change the network from one access point to another. This network change is done without any interruption.
Recent models are equipped with PoE + technology (Power over Ethernet Plus) which avoids the installation of electrical outlets everywhere near access points.
Features are now available on a lot of access points:
- Access control list: They allow the restriction of access to certain people,
- The Clustering: It is a single point of administration for all access points.
- Security and channel settings:
. the best solution for security is WPA2 encryption,
- the channel chosen must correspond to the one with the least traffic. You may find the Windows version Netspot software useful.
What is a Wi-Fi amplifier?
The Wi-Fi amplifier is a device whose main purpose is to increase, boost and extend the signal from your box.
We use the following terms to describe it:
- improve your Wi-Fi connection, improve your internet connection,
- boost your Wi-Fi connection, boost your internet connection, boost connection, booster Wi-Fi,
- optimize your Wi-Fi connection,
- improve your Wi-Fi, speed up the internet, speed up connection speed,
- have a better wireless Wi-Fi, have a better connection,
- amplify the signal, increase the speed.
Unfortunately, this solution is not effective when you have a difficult environment (microwave, thick walls, etc.). There, the wired connection is essential. In addition, the name of the Wi-Fi is necessarily different from that of your internet box.
The signal amplifier works in a simple way. Just plug it into a wall outlet.
Since it aims to increase the Wi-Fi signal, it is wise to have it in an area where the connection is not weak. Otherwise, your amplified signal will probably be weaker than that delivered by your box.
The efficiency of an amplifier varies according to the models offered. What you need to know is that a good amplifier should at least double the signal from the router. Try to avoid obstacles (wall, microwave, metal objects, etc.) to achieve this.
As a recommendation, do not buy a powerful amplifier but not compatible with the router. You should also not buy a low-speed amplifier when the router uses high frequencies.
What is a Wi-Fi repeater
The Wi-Fi repeater (sometimes Wi-Fi repeater) is a box which, put in the Wi-Fi coverage area of the main Wi-Fi router, will broadcast the received signal in an area not covered by the Wi-Fi connection in the House. It extends the coverage of the wireless Wi-Fi network without increasing it. By the way, it will reproduce the Wi-Fi signal identically and unlike the amplifier, it keeps the same name of the Wi-Fi network as that of the router.
It does not increase the bandwidth or the speed of connection but it transmits the signal with a slight loss.
Generally and for people who live in large houses, this coverage cannot not reach every corner of the dwelling. There comes the need for the repeater.
How does it work ?:
The wireless devices will receive the signal given by your box or the router placed in a specific place. Basically, it will create a new network so that the coverage reaches all corners. Its location is essential to give the best quality of the internet connection.
The current carrier current known as CPL allows local transit of digital data via wall outlets.
Principle of operation:
The electric current flows in the cables on a low frequency, generally, of 50 Hz. The use of these same cables made it possible to pass the data at a very high frequency in MHz. Thus, no interference is possible.
How to do ?:
All you need is a PLC kit which is easy to install. The first PLC adapter will be used for the link between the router (adsl box or modem) and the nearest electrical outlet while the second will be used to recover this data throughout the house. But the problem that persists and remains insolvent to this day is the more we put PLC adapters to connect its peripherals to the internet and the more we divide the initial speed.
The Wi-Fi extender that is the PLC is safer than a local Wi-Fi internet network, but this security is not absolute although the signal is blocked at the level of the house's electric meter.
To enhance security, there is the possibility of installing a data encryption system on the PLC adapters which can be activated at any time.
How to choose a repeater?
Choice to be made
Three essential factors are involved in choosing the best device:
- The signal range:
The more the object extends the signal, the better it will be.
- The signal gain:
The consistency of the signal is an important factor.
The Wi-Fi connection is better when the radiation emitted by the transmitter is large.
Other selection criteria, namely:
- the standard,
- the presence of an Ethernet cable,
- the presence of a pull-out socket,
- the presence the WPS function: configuration button.
The choice of Wi-Fi amplifiers displayed is made according to the cheap price and the best in quality. This price fluctuates between around twenty euros and around forty.
This varies with the services offered:
- A female socket to avoid taking up the wall socket used,
- An external antenna which is far better than the indoor antenna,
- The Wi-Fi standard used.
There are several famous brands on the market for this product. The best known by far are Netgear, followed by Devolo, TP-Link TL as well as other brands which are of Asian manufacture especially Chinese and which are of very good quality, better than renowned apparatuses.
We are going to you talk about these latest Wi-Fi repeaters that have today invaded the major internet sales platforms.
In summary, the access points, Wi-Fi repeaters or amplifiers are there to make your life easier by giving you the possibility of internet access anywhere in your home without much effort. Cables lying around everywhere are not necessarily necessary except in the first case.
To have all possible internet connections, you should know that several devices are equipped with all the functions:
- Access point with its RJ45 cable,
- Wi-Fi repeater,
- Wi-Fi amplifier,
- Router with its Gigabit Ethernet ports (Fast Ethernet).
All these devices can power all kinds of boxes, decoder, receiver and consoles.
