Ubuntu下成功安装台式机网卡realtek的rtl8188eu芯片驱动并实现AP功能

1,下载驱动

https://github.com/lwfinger/rtl8188eu

使用注意:

https://github.com/lwfinger/rtl8188eu/issues/3

2.编译安装

 $make  
    $sudo make install 

3.关于hostapd的配置文件

# Basic configuration

interface=wlan0
ssid=11111
channel=10
#bridge=br0

# WPA and WPA2 configuration

macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=3
wpa_passphrase=123456789
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

# Hardware configuration

driver=rtl871xdrv
ieee80211n=1
hw_mode=g
device_name=RTL8192CU
manufacturer=Realtek
••••••••••

 4.基本操作

sudo ifconfig wlan1 up //打开端口
sudo hostapd -B /etc/hostapd/hostapd.conf
sudo hostapd  -d /etc/hostapd/hostapd.conf
sudo hostapd /etc/hostapd/hostapd.conf

5.手机搜索不到SSID(wifi热点的名字)

在网上找到

手机收不到SSID
系统是archlinux,做软ap。之前是运行一个ad-hoc的脚本,有些android手机不支持ad-hoc模式,就安装了hostapd,
运行 # hostapd  -d /etc/hostapd/hostapd.conf
手机可以连上&上网
重启电脑再运行hostapd,手机就不能获取ip地址了。必须运行ad-hoc脚本,再运行hostapd才行。
是不是哪里没有设置好?
另外,手机连上ap后似乎不能建立安全链接,wifi信号是灰色的不是蓝色,gtalk不能登录,但能看到在线好友?????

于是就编辑了一个ad-hoc的wifi热点,热点名称与hostapd中配置的名称一样,这里为”11111“

显示“11111”已连接上网络,然后就可以收到SSID 的信号(信号由hostapd产生)。

6.手机收到信号后,连接不上,显示身份信息验证失败

后来尝试了很多办法

你可以检查:
1、你的AP或无线路由器和你终端的加密方式是否相同
2、密钥有没有设置对
3、密钥是字符还是ASCII码
4、无线网络经常会有相同SSID的,你联的无线网络是不是要联的。

还是不行,后来想想hostapd产生的SSID应该与ad-hoc产生的wifi热点没关系,只是需要启动一下ad-hoc而已。

看了看手机收到的SSID,选定静态配置(没有用到DHCP),然后及可以并使用了。

sudo gedit /etc/hostapd/hostapd.conf

 IPV4设置方法:1.与其他计算机共享

                           需要IPV4完成这个连接(不选)

无线提示连接上, 产生稳定的SSID,连接不上,hostapd没有反应。

        需要IPV4完成这个连接(选)

手机能连接上网,容易断线。

 

        2.已禁用

无线提示连接不上,产生不了稳定的SSID。
