我安装这个USB网卡驱动，好像驱动不了，还是安装错了？？？
我参考了

https://askubuntu.com/questions/1047832 ... 04-version

和

https://github.com/lwfinger/rtl8188eu

安装过程

sudo apt-get update
sudo apt-get install -y linux-headers-$(uname -r) build-essential git
git clone https://github.com/lwfinger/rtl8188eu
cd rtl8188eu
make all
sudo make install
sudo insmod 8188eu.ko
sudo dkms add ./rtl8188eu
sudo dkms build 8188eu/1.0
sudo dkms install 8188eu/1.0

之前也参考了

安装过程编译出错了，我没看懂出错问题在哪，不懂这个驱动编译。

这台式电脑有线网卡是可以用，但是距路由器太远了，win7一直用此USB网卡连接wifi方式上网，最近了装了pureos,ubuntu,lubuntu,linuxmint,，要么卡要么类似马赛克桌面卡屏，没法用。

体验各种linux版本后也只有xubuntu18.04适合我的电脑，主要是中文语言和wubi输入法体验。

不太愿意使用盗版win7,所以转用linux桌面系统。

请帮助我，谢谢！

[astolia]

你在2楼做的完全没用，因为根本不是同一个型号。
3楼的编译出错应该是因为源代码是好几年前的了，跟新内核不兼容。
现在的内核中已经有驱动了，你可以先试一下它有没有效。sudo modprobe mt7601u
如果没效，再安装内核源代码sudo apt install linux-source，按 https://github.com/kuba-moo/mt7601u/iss ... -352250127 的做法修改驱动源代码后重编译驱动

[skswujian]

内核中已经有驱动了
sudo modprobe mt7601u

没启动成功

安装内核源代码
sudo apt install linux-source
正在读取软件包列表... 完成
正在分析软件包的依赖关系树
正在读取状态信息... 完成
linux-source 已经是最新版 (4.18.0.11.12)。

按 https://github.com/kuba-moo/mt7601u/iss ... -352250127 的做法修改驱动源代码后重编译驱动

1.从https://www.kernel.org/下载内核源代码linux-4.18.17.tar.xz

2.从linux-4.18.17.tar.xz解压获得drivers/net/wireless/mediatek/mt7601u驱动文件

3.这一步没搞明白，仔细看了下phy.c里

return ret;
ret = mt7601u_mcu_calibrate(dev, MCU_CAL_RXIQ, 0);
if (ret)
return ret;
ret = mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->dpd_temp);
if (ret)
return ret;

void mt7601u_phy_recalibrate_after_assoc(struct mt7601u_dev *dev)
{
mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->curr_temp);

mt7601u_rxdc_cal(dev);
}

一模一样的，不作修改。


4.编译make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
结果输出为

make: 进入目录“/usr/src/linux-headers-4.18.0-11-generic”
Makefile:982: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"
Building modules, stage 2.
MODPOST 1 modules
CC /home/pc/mt7601u/mt7601u.mod.o
LD [M] /home/pc/mt7601u/mt7601u.ko
make: 离开目录“/usr/src/linux-headers-4.18.0-11-generic”

5.删除设备？这个没搞懂，是不是拨出USB网卡？

6.删除mt7601模块sudo rmmod mt7601u

7.载入mt7601u.ko模块sudo insmod ./mt7601u.ko

8.插入USB网卡

9.没看懂这英文说什么，抱歉

10.也没看懂什么，英文不好。。。

我不知道错在哪，重启还是没有驱动成功。

2.从linux-4.18.17.tar.xz解压获得drivers/net/wireless/mediatek/mt7601u驱动文件

不用去下载的，你已经安装了 linux-source，直接到/usr/src/linux-source-4.18.0/下面就是源码了

3.这一步没搞明白，仔细看了下phy.c里

return ret;
ret = mt7601u_mcu_calibrate(dev, MCU_CAL_RXIQ, 0);

return ret;
ret = mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->dpd_temp);

{
mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->curr_temp);

mt7601u_rxdc_cal(dev);
}

一模一样的，不作修改。

你仔细看看链接里的，某些行前面有//，即把那些行注释掉让它不生效。你吧带//的行删掉也行

5.删除设备？这个没搞懂，是不是拨出USB网卡？

是的。

remove re•move /rɪ'muːv/
VT
1.移开，拿走
He removed his desk to another corner. 他把办公桌移到了另一个角落。
2.去掉，除掉，消除
What do you advise for removing grease stains from clothes? 你认为该如何消除衣服上的油污？
3.撤职；辞退
He was removed from his position. 他被辞退了。

9.没看懂这英文说什么，抱歉

叫你做了上面的操作后用dmesg看设备插入后内核的输出中有没有输错的地方

10.也没看懂什么，英文不好。。。

是说这个只针对当前的内核，一旦你升级了内核，就要重来一遍

不用去下载的，你已经安装了 linux-source，直接到/usr/src/linux-source-4.18.0/下面就是源码了

嗯，linux-source-4.18.0/有源码包，从里面提取了mt7601u驱动文件。

某些行前面有//，即把那些行注释掉让它不生效。

已注释掉了

没发现usb网卡驱动成功，重启也一样。

用dmesg看设备插入后内核的输出中有没有输错的地方

这个demesg还不会使用，小白不会看呀。

从dmesg的输出来看，你这个是个3G/4G上网卡之类的东西啊

[skswujian]

从dmesg的输出来看，你这个是个3G/4G上网卡之类的东西啊

是这个代码么

[ 2679.955493] usb 1-1: GSM modem (1-port) converter now attached to ttyUSB0

问题是我这个USB网卡不是3G/4G上网卡呀，是FAST迅捷无线USB网卡，型号是FW150UH

FW150UH(免驱版)

150M高增益无线USB网卡

硬件版本V2

我有三个这个usb网卡，光linux驱动就难搞死了，若能解决就好啦。一直在想这个linux无线驱动问题如何解决。

之前解决了debian如何安装BCM4352的无线驱动问题，现在就这个无线USB网卡如何安装驱动，心病呀。

[skswujian]

重新操作，dmesg实时输出信息（感觉还是驱动有问题吧？）
