How to optimize your wifi connection
Modem and wifi router
Modem and wifi router, what is it
The modem is the device provided by the internet provider. Its function is to bring information that is on the web.
The wifi router is the device that takes this modem information and distributes it.
Currently, most internet providers deliver a 2-in-1 device called an internet box that simultaneously includes the combined modem and wifi router.
The wifi signal is propagated from your internet box on the radio bands. Each band is a way propagating information. But the use of the Internet has seen a huge explosion and new devices connected consume large quantities. For this reason, manufacturers have expanded their ranges by providing one-band, dual-band and even three-band wifi routers. All use both 2.4 Ghz and 5 Ghz channels.
On the other hand, the standards of wifi are constantly growing. This is how the latest 802.11ac standard has a speed that exceeds the Gigabit/s. This standard has recently seen an improvement. It is now accompanied by the MU-MIMO (Multi-user with Multiple Inputs and Outputs) feature.
These criteria of choice are only to be considered when buying a router:
- Router Speed: The correspondence of standards to speeds is as follows:
. 802.11n flow about 450 Mbits/s,
. 802.11ac flow about 1300 Mbits/s sur 5 Ghz,
. 802.11ac with MU-MIMO about 1700 Mbits/s.
- Antennas: Routers that have external antennas deliver more powerful signals. These antennas are generally directional and adjustable to achieve the best range possible.
- Ethernet ports: To get the optimal speed offered by the internet provider, there is no better than using Ethernet ports.
AP access point
Definition of an access point
The access point is a device that creates a wireless LAN or WLAN. It is any terminal used powered by LAN to broadcast the wifi signal received from a router, a switch or hub over a wired link (Ethernet cable). This signal can come directly from your adsl box via its Ethernet port.
The access point is the recommended device and the most suitable for businesses because it can handle more than 60 connections at the same time.
By installing access points everywhere, everyone can move between offices and within the factory without any risk of loss of connection.
Used devices automatically change network from one access point to another. This network change is done without any interruption.
Recent models feature Power over Ethernet Plus (PoE +) technology to prevent the installation of electrical outlets anywhere near access points.
Features are present now on a lot of access points:
- Access control list: They allow the restriction of access to certain people,
- Clustering: This is a single point of administration for all access points.
- Security settings and channel settings:
. the best solution for security is WPA2 encryption,
- the chosen channel must match the one with the least traffic. Netspot Windows software can help you.
What is a wifi amplifier?
The wifi amplifier is a device whose main purpose is to increase, boost the signal from your box.
The following terms are used to describe the thing:
- improve your wifi connection, improve your internet connection,
- boost its wifi connection, boost its internet connection, boost connection, boost wifi,
- optimize your wifi connection,
- enhance your wifi, accelerate internet, speed up connection speed,
- have a better wifi, have a better connection,
- increase the flow.
Unfortunately, this solution is not effective when you have a difficult environment (microwaves, thick walls, etc.). There, the wired connection is essential. In addition the name of the wifi is necessarily different from that of your internet box.
The wifi amplifier works in a simple way. Just plug it into a wall outlet.
Since it aims to increase the wifi signal, it is advisable to have it in an area where the wifi is not weak. Otherwise, your amplified signal will probably be weaker than the one delivered by your box.
The efficiency of an amplifier varies according to the proposed models. What you need to know is that a good amplifier must at least double the signal from the router. Try to avoid obstacles (wall, microwave oven, metal objects, etc.) to achieve this.
As a recommendation, do not buy a powerful amplifier but not compatible with the router. Do not buy a low-rate amplifier when the router uses high frequencies.
What is a wifi repeater?
The wifi repeater is a box that, put in the wifi coverage area of the main wifi router, will broadcast the received signal in an area not covered by the wifi in the house. It extends the wireless network coverage of the wifi without increasing it. In fact, it will reproduce the wifi signal in the same way and unlike the amplifier, it retains the same wifi network name as that of the router.
It does not increase the bandwidth nor the connection speed but it transmits the signal with a slight loss.
Generally and for people who live in big houses, this blanket can not reach every corner of the house. There, intervenes the necessity of the repeater.
How does it work ?
The device will pick up the signal given by your box or the router set in a determined place. Broadly speaking, it will create a new network so that the coverage reaches every corner. Its location is essential to give the best quality of the internet connection.
Power line carrier
The powerline line known as PLC allows the local transit of digital data via wall outlets.
Principle of operation
Principle of operation
The electric current flows in the cables on a low frequency, usually 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 ?
You just need two PLC adapters. The first PLC adapter will be used to connect the router (box adsl or modem) and the nearest electrical outlet while the second will be used to recover these data throughout the house. But the problem that persists and remains insolvent to date is the more we put PLC adapters to connect its devices to the internet and the more we divide the initial flow.
The PLC expander wifi is safer than a local wifi network, but this security is not absolute although the signal is blocked at the home electricity meter.
To enhance security, there is the possibility to install a data encryption system on LCC adapters that can be activated at any time.
How to choose your wifi repeater?
How to choose?
Choice to do
Three essential factors fall into the choice of this device:
- The scope of the device:
The more the object extends the signal, the better it will be.
- The signal gain:
Constancy of the signal is an important factor.
- The cover:
The wifi connection is the best solution for the space covered by the transmitter is great.
D'autres critères de choix à savoir :
- la norme, il pas très loin du routeur,
- la présence d'un câble Ethernet,
- la présence d'une prise gigogne,
- la présence de la fonction WPS : bouton de configuration.
Price of the device
The choice of wifi amplifiers displayed is made according to the lowest price and the price cheap . This price oscillates between twenty euros and forty.
This varies with the services offered:
- A female socket to avoid avoid condemning the wall socket,
- An external antenna that is far better than the indoor antenna,
- The wifi standard used.
There are several reputable brands of this product on the market. The best known are by far Netgear, come next Devolo, TP-Link TL as well as other brands that are mainly Asian-made in Asia (especially Chinese) and are at first very good quality and then at the lowest price.
We are going to talk about these last wifi repeaters which have, today, invaded the major internet sales platforms.
In summary, 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 a great effort. Cables lying around are not necessarily necessary except for the first case.
To have all the possible internet connections, you will have to know that several devices have all the functions:
- Access point with its RJ45 cable,
- Wi-Fi Repeater,
- Wi-Fi amplifier,
- Router with Gigabit Ethernet ports (Fast Ethernet).
All these devices can power all kinds of boxes, decoder, receiver and consoles.
