Wi-Fi adapters are used to implement the wireless Internet connection function on the devices, where such support is not available.
Adapters are usually installed in the computer's USB-port, as well as the different supported data rate and signal reception level.
The types of adapters
In addition to the USB-adapter, there are PCI, PCI-Expressand PCMCI-adapters. They are full of network cards capable of transmitting data at speeds higher than the value of 600 Mb / s. Such devices are installed inside the computer and connect through the appropriate slot on the motherboard.
USB-adapter The advantage is theirportability - they can easily be transferred and used in other computers. However, the data rate and signal reception level in such devices may be less expensive than the PCI-E card. This is due to USB-interface and limitations. It should be noted that some USB-support adapter 150 and connection speed of 300 Mbit / sec. Such indicators are usually sufficient for the home wireless network and comfortable surfing the Internet.
Working with the device
Installing the adapter is made in accordanceslot on the computer according to the instructions that comes with the device. After installing the device in the slot is tuned, ie, Driver installation is required in order to support wireless data adapter in the system. The driver can be installed from a disc, which usually comes in the same package with the device, and by downloading the driver installation file via the Internet from the official site of the manufacturer. Once the driver has been installed, start setting network parameters, ie, Choices in terms of Internet access. Application parameters can be used directly in the system on a computer.
When selecting an adapter is necessary to pay attention notonly on its speed characteristics, but also on the company-manufacturer. The most popular and high-quality adapters are manufactured by companies such as D-Link, Asus, TP-Link, Zyxel, LinkSys. The most expensive models from data producers have the opportunity to not only receive, but also the distribution of Internet signal. Thus, some adapters can act as a router, to be able to connect using the telephone or any other device to the wireless network Wi-Fi.
When you select a note on the network standard,that device uses for data transmission. Thus, most high-speed is standard 802.11n, which supports data rates up to 600 Mbit / s to create the ideal conditions.
