1. 看看 IPv4 網路 通不通
把下面指令 複製 貼進終端機 執行
1-1. ping -c 3 127.0.0.1
1-2. ping -c 3 192.168.1.103
1-3. ping -c 3 192.168.1.1
1-4. ping -c 3 198.71.86.201
1-5. ping -c 3 forum.ubuntu.org.cn
1-6. sudo cat /etc/resolv.conf
把結果直接 選取/複製/貼上來

在办公室和家连有线网都没有问题。手机上无线网也没有问题。

實際要 ping 的 IPv4 是根據
sudo ifconfig -a
sudo route -nv
得來的
請提供
sudo ifconfig -a
sudo route -nv
sudo cat /etc/resolv.conf
以免遺漏重要資訊

1. 你的 192.168.0.111 是 dhcp auto 還是 dhcp static 還是其他方式獲得的 ?
已经按上次经验删除了再次出现的多余的IP路径
sudo route del -net 169.254.0.0 netmask 255.255.0.0 wlan0
2. 表示 你的無線網卡網址設定是有問題的 才會每次開機都會自動出現
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0
2-1. 請描述一下 你的無線網卡 如何設定

动态获取,但没有明确设置dhcp auto。没有做任何设定。

1. 沒有 wlan0
2. /etc/network/interfaces.d/ 有什麼跟 wlan0 有關的設定檔嗎

不知还是之前 BCM4313 那台机器吗?两款开源驱动都支持不佳,换用私有驱动 broadcom-sta-dkms 试试。
lspci -k 看到加载 wl 说明成功换成私有驱动。
根据你上次提供的结果,ping 114.114.114.114 要60毫秒左右,显然是有问题的?不知有线网是否也是这个结果?

没设定过wlan0
1. 把下面指令 複製 貼進終端機 執行
1-0. uname -r
1-1. sudo lspci -knn
1-1-1. 如果無線網卡是 usb 裝置 請增加
sudo lsusb
1-2. sudo lshw -numeric -class network
1-3. sudo rfkill list all
1-4. sudo nmcli dev status wlan0
1-5. sudo dhclient -v
1-6. sudo iwlist scan
把你的 ESSID 那一段落 直接 選取/複製 貼上
http://paste.ubuntu.com
1-7. sudo dkms status
1-8. sudo cat /etc/NetworkManager/NetworkManager.conf
1-9. sudo cat /etc/network/interfaces
1-10. sudo cat /etc/udev/rules.d/70-persistent-net.rules
把結果直接複製 貼到
http://paste.ubuntu.com
再把回應網址
http://paste.ubuntu.com/xxxxxxx
貼上來
2. 測試期間 暫時從 Bios 關閉 主板內建有顯網卡
等測試成功後 需要時 才決定是否打開 主板內建有顯網卡

现在安装了 broadcom-sta-dkms,能无线上网了,但不知道如何查看驱动信息,是这样吗:
