Como instalo un driver para mi adaptador wifi en ubuntu??

Tengo unos driver en el cd pero me dice que no esta para ubuntu y si para otras distros.

Release Date: 2006-02-09, ver 1.2

RTL8187 Linux driver version 1.2

--This driver supports RealTek RTL8187 Wireless LAN driver for

Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006,

SUSE 9.3/10.1/10.2, Gentoo 3.1, etc.

- Support Client mode for either infrastructure or adhoc mode

- Support WEP and WPAPSK connection

< Component >

The driver is composed of several parts:

1. Module source code



2. Script ot build the modules


3. Script to load/unload modules



4. Script and configuration for DHCP



4. Supplicant source code:


5. Example of supplicant configuration file:


< Installation >

Runing the scripts can finish all operations of building up modules

from the source code and start the nic.

1. Build up the drivers from the source code


2. load the driver module to kernel and start up nic


< Set wireless lan MIBs >

This driver uses Wireless Extension as an interface allowing you to set

Wireless LAN specific parameters.

Current driver supports "iwlist" to show the device status of nic

iwlist wlan0 [parameters]


parameter explaination [parameters]

----------------------- -------------

Show available chan and freq freq / channel

Show and Scan BSS and IBSS scan[ning]

Show supported bit-rate rate / bit[rate]

Show Power Management mode power

For example:

iwlist wlan0 channel

iwlist wlan0 scan

iwlist wlan0 rate

iwlist wlan0 power

Driver also supports "iwconfig", manipulate driver private ioctls, to set


iwconfig wlan0 [parameters]


parameter explaination [parameters] constraints

----------------------- ------------- ------------------

Connect to AP by address ap [mac_addr]

Set the essid, join (I)BSS essid [essid]

Set operation mode mode {Managed|Ad-hoc}

Set keys and security mode key/enc[ryption] {N|open|restricted|off}

For example:

iwconfig wlan0 ap XX:XX:XX:XX:XX:XX

iwconfig wlan0 essid "ap_name"

iwconfig wlan0 mode Ad-hoc

iwconfig wlan0 mode essid "name" mode Ad-hoc

iwconfig wlan0 key 0123456789 open

iwconfig wlan0 key off

iwconfig wlan0 key restricted 0123456789

< Getting IP address >

After start up the nic, the network needs to obtain an IP address before

transmit/receive data.

This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS"

command, or using DHCP.

If using DHCP, setting steps is as below:

(1)connect to an AP via "iwconfig" settings

iwconfig wlan0 essid or

iwconfig wlan0 ap XX:XX:XX:XX:XX:XX

(2)run the script which run the dhclient



dhcpcd wlan0

(Some network admins require that you use the

hostname and domainname provided by the DHCP server.

In that case, use

dhcpcd -HD wlan0)


WPA_SUPPLICANT help the network to communicate under the protection of WPAPSK


(1)Unpack source code of WPA supplicant:

tar -zxvf wpa_supplicant-0.4.9.tar.gz

cd wpa_supplicant-0.4.9

(2)Create .config file:

cp defconfig .config

(3)Edit .config file, uncomment the following line:


(4)Build WPA supplicant:


If make error for lack of <include/md5.h>, install the openssl lib(two ways):

1. Install the openssl lib from corresponding installation disc:

Fedora Core 2/3/4/5(openssl-0.9.71x-xx), Mandrake10.2/Mandriva10.2(openssl-0.9.7x-xmdk),

Debian 3.1(libssl-dev), Suse 9.3/10.0/10.1(openssl_devl), Gentoo(dev-libs/openssl), etc.

2. Download the openssl open source package from www.openssl.org, build and install it.

(5)Edit wpa_supplicant.conf to set up SSID and its passphrase.

For example, the following setting in "wpa1.conf" means SSID

to join is "BufAG54_Ch6" and its passphrase is "87654321".





pairwise=CCMP TKIP

group=CCMP TKIP WEP104 WEP40




(6)Execute WPA supplicant (Assume 8187 and related modules had been


./wpa_supplicant -D ipw -c wpa1.conf -i wlan0 &

para instalar controladores wifi te recomiendo qued conectes primero el pc mediante ethernet y vas a sistema&gt;administracion&gt;controladores adicionales y ahi deberia salir el controlador

al menos los controladores de broadcom se instalan asi
Alexowolff dijo:me agarra el ruter alfa, lo malo es que se corta a cada rato y en windows no me pasa eso, creo que es por el driver... eds piensan lo mismo??

has lo que te dice SMOSA, si te aparecen dos opciones de habilitar un driver, te recomiendo que te instales el que dice &quot;controlador inalambrico Broadcom STA&quot;, a mi tambien me paso lo mismo que a ti cuadno active el que decia wireles driver. y ahora me anda de joyas. ojala y te sirva la ayuda,

sino postea por aca que opciones te da de habilitar driver.
Provastes instalando los driver de Windows con ndiswrapper los tenes que tener de la forma .inf (o si instalas wine, corres el .exe del instalador Wifi , y los drivers van a parar a una carpeta, de ai los buscas con ndiswrapper )
