Routez Internet depuis un adaptateur WiFi intégré vers un adaptateur USB WiFi, qui servira de point d'accès ou de point d'accès WiFi.

Mon ordinateur portable est connecté à Internet via une carte WiFi intégrée. J'ai un autre adaptateur USB WiFi. Je souhaite créer un point d'accès/point d'accès WiFi sur un adaptateur USB WiFi.

Je souhaite connecter plusieurs périphériques sur un adaptateur USB WiFi pour accéder à Internet sur ces périphériques connectés.

Comment puis-je acheminer Internet de la carte WiFi intégrée à l'adaptateur WiFi USB? Mon ordinateur portable utilise Ubuntu 14.04 LTS 64-bit

Je pouvais le faire entièrement via le gestionnaire de réseau en créant une nouvelle connexion "sans fil (partagée)" qui passait par défaut en mode Ad-Hoc. Cela devrait probablement suffire si vous essayez d'utiliser votre ordinateur portable comme répéteur pour d'autres périphériques.

N'oubliez pas de définir votre sécurité WiFi sur "WPA/WPA2 Personal" et de définir une clé sécurisée.

Vous pouvez voir deux versions différentes de la connexion avec les adaptateurs respectifs entre parenthèses, dans mon cas, wlan0 était l'adaptateur interne et wlan1 le dongle USB.

Edit: Il y a un autre question avec d'excellentes réponses sur la façon d'installer le pilote. Apparemment, il existe deux ports différents ( 1 , 2 ) du pilote, les deux ayant été mis à jour ce mois-ci.
Si l’un ne fonctionne pas pour vous, supprimez le module du noyau et essayez l’autre.

Donc, vous voulez faire un répéteur wifi?

En supposant que vous ayez le pilote nécessaire pour votre EW-7811Un dongle; sinon, essayez d'utiliser le paquet PPA sur ppa:hanipouspilot/rtlwifi et le rtl8192cu-dkms.

TL; DR

Si vous ne pouvez pas supporter de tout lire et que vous voulez être nourrir une cuillère à la place, exécutez ce script , fermez les yeux et croisez les doigts.

Comment faire

  1. Vous avez besoin de hostapd mais d'une version spécialement en raison du pilote realtek insuffisant. Vous devrez désinstaller la version d'ubuntu (si elle est installée) et installer une version corrigée.

    Vous pouvez télécharger le fichier original depuis realtek.com.tw (mais j'utilise ici le même fichier depuis un dépôt d'utilisateur github):

    Sudo apt-get remove hostapd
cd /tmp
wget https://github.com/XiaoxiaoPu/hostapd-8192cu/raw/master/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.Zip
unzip RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.Zip
cd RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911
cd wpa_supplicant_hostapd
tar -zxf wpa_supplicant_hostapd-0.8_rtw_r7475.20130812.tar.gz
cd wpa_supplicant_hostapd-0.8_rtw_r7475.20130812
cd hostapd

    Vous pouvez (devez?) Utiliser ce fichier et l'enregistrer sous le nom .config

    # Example hostapd build time configuration
#
# This file lists the configuration options that are used when building the
# hostapd binary. All lines starting with # are ignored. Configuration option
# lines must be commented out complete, if they are not to be included, i.e.,
# just setting VARIABLE=n is not disabling that variable.
#
# This file is included in Makefile, so variables like CFLAGS and LIBS can also
# be modified from here. In most cass, these lines should use += in order not
# to override previous values of the variables.

# hostapd depends on strong random number generation being available from the
# operating system. os_get_random() function is used to fetch random data when
# needed, e.g., for key generation. On Linux and BSD systems, this works by
# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
# properly initialized before hostapd is started. This is important especially
# on embedded devices that do not have a hardware random number generator and
# may by default start up with minimal entropy available for random number
# generation.
#
# As a safety net, hostapd is by default trying to internally collect
# additional entropy for generating random data to mix in with the data
# fetched from the OS. This by itself is not considered to be very strong, but
# it may help in cases where the system pool is not initialized properly.
# However, it is very strongly recommended that the system pool is initialized
# with enough entropy either by using hardware assisted random number
# generatior or by storing state over device reboots.
#
# If the os_get_random() is known to provide strong ramdom data (e.g., on
# Linux/BSD, the board in question is known to have reliable source of random
# data from /dev/urandom), the internal hostapd random pool can be disabled.
# This will save some in binary size and CPU use. However, this should only be
# considered for builds that are known to be used on devices that meet the
# requirements described above.
#CONFIG_NO_RANDOM_POOL=y

    Ensuite

    make
Sudo make install

  2. On peut utiliser create_ap lequel un petit script d'aide pour configurer le point d'accès wifi. Il prend en charge la configuration de hostapd, iptables si nécessaire (lors de l'utilisation de NAT). C'est un remplacement pour l'ancien ap-hostspot.

    cd /tmp
git clone [email protected]:oblique/create_ap.git
Sudo cp create_ap/create_ap /usr/local/bin/create_ap
Sudo apt-get install dnsmasq-base iptables # if you don't have them already

  3. Vous créez ensuite le point chaud avec create_ap

    Sudo create_ap -w 2 -c 6 --driver rtl871xdrv wlan1 wlan0 MyHotspot mysecretpassword

    Vous devez utiliser la méthode par défaut (NAT) car vous ne pouvez pas relier 2 interfaces wifi.

    En supposant que la clé USB est wlan1 et la carte intégrée wlan0. Utilisez un canal différent (au moins avec un intervalle de +/- 3 canaux) que le canal utilisé par wlan0.

Terminé! Vous devriez avoir votre configuration AP et le client devrait accéder au net via votre carte wifi intégrée.

A partir de sources multiples mais utilisant principalement le script de paquet AUR hostapd-8192c

La désinstallation

Sudo rm /usr/local/bin/hostapd /usr/local/bin/hostapd_cli /usr/local/bin/create_ap
