    How to configure a wifi usb nic on Linux

    Basically, it is true that todays usb wifi adapter are supported on the new distros of linux. This requires a wireless card or WLAN USB adapter with much support the chipset. This one is the prime requirement of the same. Is there any working Linux method by which I can run the usb nic adpater. I want to use can use a wireless Ethernet adapter on both the client and the access point mode, sometimes even Ethernet Bridge. But that can be a dream, while on Windows there is nothing much to fear out. Wireless cards and adapters under Linux often cause problems due to the difference in models. What methods are used to install a wifi usb apter.

    Many WLAN hardware mostly supports Linux based systems. Therefore, you should just try as a beginner for first time the tools. However, more and more work on linux if the wireless card is properly supported in linu. The wireless cards are becoming better recognized and often just walk directly. The wifi is configured with iwconfig, which belongs to package wireless-tools. It is not present by default on debain based system. To install them run - sudo aptitude update. Then for any upgrade run - sudo aptitude safe-upgrade. Later on you can run setup of wifi tool by - sudo aptitude install wireless-tools.

    To configure networking under Debian, the easiest way is to configure / etc / network / interfaces and / etc / resolv.conf. It is configured as DHCP, meaning that the IP address is not fixed in the debian system, but obtained from the router via DHCPREQUEST. I called this file / etc / network / interfaces.wifi. Before doing anything lets first see if Linux recognizes your card natively, that is to say that the drivers are already built and installed in Ubuntu. To do this, enter the following command in a terminal / console - iwconfig. If you receive a message back containing the interface wlan. If there is no wifi found then the card is not supported at all on the linux platform.

    The installation of a wireless card consists of the following steps. First you need a driver and then install the kernel to activate the same. Later on you will need to start scripts and make settings for the wireless card. In itself is the installation of a wireless card no bigger problems, with even take the big distributions such as Suse, Mandriva or Fedora already most of the work, the distribution-specific tools. With each new hardware that you include in the computer, of course, first you have to install the drivers. If your hardware is not automatically detected, it looks to be first if it is not supported by the kernel.

    If the hardware is not supported by the kernel, so you have to install a driver back on the manufacturer or a Windows driver by using ndiswrapper. Since the RT2500 chipset under Linux is well supported and included even in the software management (Portage) Gentoo, the driver can now be installed with emerge. Users of a distribution other than need to download the source code itself and follow the instructions to install.

    First check that the usb adapter supports your linux system or not. If the card is installed then the next step is to configure the card. If you have no graphical tool to configure, make of this manually, but this should pose no problem. On the Linux system, the Wireless Tools installed, so you can configure with the command iwconfig the wireless card. On whose system of this command is unknown, should re-install the wireless tools. If you type iwconfig, the wireless card should be displayed. Iwconfig shows us all the important information about the wireless card, even among other things, that the wireless card is doing business as ra0.
