关于win7和ubuntu16.04的usb无线网卡驱动问题

[风语者97321]

其中一台电脑，我在装ubuntu之前win7上的usb无线网卡可以正常使用，装了ubuntu过后win7和ubuntu上都不能用无线网了，设备管理器中也看不到无线网卡驱动，重新拔了再插上后又可以正常使用，但是我启动了ubuntu再重启就又不能使用了，这是为什么呢？另外一台电脑是可以搜到无线网，但是连接不上，重插也能变好。

優先檢查
Win 7 及 Ubuntu 關機後 是否已經把所有的 耗電裝置 全部徹底關閉
例如 遠端遙控網路喚醒 ?

可以正常使用

1. 把下面指令 複製 貼進終端機 執行
1-1. sudo lspci -knn
1-2. sudo lsusb
1-3. sudo lshw -numeric -class network
1-4. sudo ifconfig -a
1-5. sudo route -nv
1-6. sudo rfkill list all
1-7. sudo dhclient -v
1-8. sudo iwlist scan # 選取 你的 ESSID 那一段
把結果全部直接 選取/複製/貼上來

都不能用无线网了

2. 把下面指令 複製 貼進終端機 執行
2-1. sudo lspci -knn
2-2. sudo lsusb
2-3. sudo lshw -numeric -class network
2-4. sudo ifconfig -a
2-5. sudo route -nv
2-6. sudo rfkill list all
2-7. sudo dhclient -v
2-8. sudo iwlist scan # 選取 你的 ESSID 那一段
把結果不同的指令及其回應 全部直接 選取/複製/貼上來

大神，能帮我看一下吗？我的DELL电脑“软件和更新”更改完网卡设置后能显示出无线网络，可是能搜索到别人的无线网却搜索不到我家的无线网，我在usb接口插上从网上买的无线网卡可以连接到自家wifi，具体我不知道怎么回事，还望大神指点迷津。
