我已经在论坛上搜索了两天,但似乎没有一个答案对我有用。我有一台 Acer Extensa 5630,它有一个 Intel wifi 5100。即使我就在路由器旁边,我也检测不到无线网络。奇怪的是,当我用手机创建热点时,它会自动检测并连接到它。我想我确实安装了正确的驱动程序。
这是 ifconfig:
$ ifconfig

当我从我的 Android 设备扫描并检测热点时,它看起来是这样的:

答案1
我遇到了同样的问题,您可以在终端中输入:
rfkill list
它会显示是否存在软阻塞或硬阻塞,然后您可以在终端中输入:
rfkill nosoftblock
rfkill nohardblock
或者
ifdown wlan0
ifup wlan0
然后在终端输入:
lspci
如果存在,您可以看到 wifi 名称,然后您可以在终端中输入:
lsmod wlan0
将wifi设置为用户,然后在终端输入:
lsusb -d wlan0
然后扫描wifi端口,在终端中输入:
nmap -v -iR 10000 -Pn -p port
如果网络处于睡眠状态(如果仍然不起作用),那么您可以在 /etc/network 中创建一个名为 sleeping.d 的脚本
/bin/sh
case bin/sh in
./bin/sh
nmcli nm asleep=false 'network'
end case
