A router is the device which communicates between two different networks. To receive internet broadband connectivity, either by cable or Wi-Fi, either an ADSL 2+ router, or Wi-Fi___33 802-11G compatible Access Points are requred in order to receive signals. ADSL modems increase the flow of data whereas 802-11n Series provide a speed of 1GB/second. In the case of a single Personal Computer connected to the internet, the cheapest solution is to use an Ethernet Cable
for a stable, flawless connectivity. In the case of multiple computers, Wi-Fi___33 Access Points are to be created for accelerated speed, greater security and to manage a Local Area Network Easily.
A router comes in the shape of a box connected to your computer. Thanks to the router, you can connect to internet broadband (cable or Wi-Fi) or you can set up a local network. Several computers can share, for example, access to multiple devices (printer, scanner ...) and internet connection.
To choose a router, you must ask yourself the following questions:
- How many computers share the same internet connection?
- How many computers will be installed in the network (sharing the printer, etc..)
A single computer VS multiple computers, what router to choose?
If you only have one PC at home, you can opt for a router connected by cable (Ethernet) for your PC to access internet broadband.
cheap solution, providing good stability of the connection, higher flow rate.
This solution is gradually disappearing in favour of the new multifunction routers (cable and Wi-Fi).
Very flexible use: ability to link one or more computers at home and thus to move, for example, with a laptop. No need to use cables.
Modem-routers from your ISP
In most cases, the router from your ISP offers a wide range of services: telephony, free access to television, simultaneous sharing of the connection through Wi-Fi. It is a modem-router connected to a main PC (Live Box, Freebox) that delivers Internet access to other computers. This router is provided when setting up your connection (or not included in the subscription).
- Advantages: simplified use, technical assistance possible price.
- Disadvantages: options for configuring a local network limited
Choosing an independent router (or modem connected to the router from your ISP) if you want to:
- Optimise internet access: increased speed, more security.
- Mount a local network: choose a router with many ports (more opportunities for interconnections between computers)
- Build a network of business: your router is accompanied by an access point (one additional case distributing Internet access, for example).
- Advantage: better security, economy bandwidth confidentiality. If you opt for this type of router, make sure it has a "Switch", a device that accelerates the transmission of data between computers.
Options and features to consider
To configure certain options (IP address, cache memory) or benefit from greater security, check your router supports the following protocols: support VPN Pass-Through, DHCP / NAT / PAT / PPPoE, UPnP
Standards required for a Wi-Fi router
Routers having Wi-Fi 802.11b standards (speed 6 Mbps) and 802.11g (25 Mbps) are the most common and most compatible.
The new routers and access points, such as D-link router dir-855, support the standard 802-11n, which will, in theory, achieve a rate close to 1 Gigabit / s.
Some modem-routers are compatible with ADSL 2 + (since 2004), which increases the maximum flow of data. But access is still limited.
