长话短说。两个问题:
- 无法
wlan0
工作, - 无法
wpa_supplicant
工作。
我编译并安装了内核4.4(修订版。EB4D55) 和改进了 rtl8xxxu 支持已启用。为了编译和安装内核,我使用了raspbian 的官方步骤。
使用新内核启动后,我这样做了:
卸载现已过时的
8192cu
模块:sudo modprobe -r 8192cu
加载新的可用
rtl8xxxu
模块:sudo modprobe rtl8892xxxu
通过以下方式确认了这一点
dmesg
:[ 1225.566010] usbcore: deregistering interface driver rtl8192cu [ 1362.505013] usbcore: registered new interface driver rtl8xxxu
但是,我有两个问题:
我似乎起不来
wlan0
:$ sudo ifdown wlan0 ifdown: interface wlan0 not configured $ sudo ifup wlan0 $ sudo ifup wlan0 ifup: interface wlan0 already configured
我似乎无法开始
wpa_supplicant
工作,可能wlan0
是因为向下:$ sudo wpa_supplicant -Dnl80211 -iwlan0 -c my_wpa.conf Successfully initialized wpa_supplicant Could not read interface wlan0 flags: No such device nl80211: Driver does not support authentication/association or connect commands Could not read interface wlan0 flags: No such device wlan0: Failed to initialize driver interface
这是我的/etc/netword/interfaces/
:
auto lo
iface lo inet loopback
iface eth0 inet manual
allow-hotplug wlan0
