Ubuntu18 上安装 tp-link 的 TL-WN725N 驱动发现没效果？

[salamanderMH]

问题描述

按这篇文章的操作来的： 下载 Github 上的驱动，下载完.zip 文件后，进行如下步骤：

unzip rtl8188eu-master.zip
cd rtl8188eu-master
sudo make
sudo make install
sudo modprobe 8188eu

重启电脑后，发现找不到无线网卡

lucy@lucy-computer:~$ iwconfig 
enp4s0    no wireless extensions.

lo        no wireless extensions.

lsusb 命令是能够看到设备的

tplink 官网都有相应的网卡驱动的，你去找找，我去年买的一个 tp 无线网卡，按照官网提供的驱动安装后没问题

[GGGG430]

@salamanderMH 我的和你版本类似，ubuntu16.04

[lcdtyph]

你这个很奇怪啊，怎么默认会让 mediatek 的驱动来处理这块网卡呢…

你把 mt7601u 暂时禁用试试：
sudo echo 'blacklist mt7601u' >> /etc/modprobe.d/blacklist-mt7601u.conf

然后重新插拔一下看看 dmesg 里有没有 8188eu 的日志

不对，我搜了一下这个型号有三种芯片，lz 这个就是 mt7601u 的，那不能按照那个教程走了，我上面这条回复也别理了，如果你执行了那条命令请执行下面的还原：
sudo rm /etc/modprobe.d/blacklist-mt7601u.conf

mt7601u 这个芯片的驱动我只搜到了针对 4.4.3 以下内核的驱动……不清楚有没有更新的

@lcdtyph
我试试

服务器上装 wifi 网卡？
桌面系统用 Ubuntu?
