整理下在ubuntu论坛安装wifi驱动的累积心得
常规方式安装 rtl8723be wifi 驱动:
问题:自动升级内核后,重启系统该wifi驱动会失效,需要重新安装.
ubuntu18.04 正确安装rtl8723be驱动步骤:
1 先安装好需要编译的东西
sudo apt-get install linux-headers-generic linux-headers-$(uname -r) gcc g++ build-essential git
2 cd切换到需要放rtlwifi_new 到目录下 ，再执行
git clone http://github.com/lwfinger/rtlwifi_new.git
3 先停止网路
sudo service network-manager stop
如果不是首次安装该驱动,在第3步后执行
$ sudo modprobe -rfv rtl8723be
删除卸载老的无线网卡驱动
4 cd 到 rtlwifi_new 目录下执行
sudo make
sudo make install
sudo modprobe -v rtl8723be fwlps=0 ips=0
5 重启
sudo reboot
6 确认是否关闭 fwlps=N ips=N
systool -v -m rtl8723be
如果查看 fwlps=Y ips=Y 的话就
echo "options rtl8723be ips=0 fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
这样首次安装rtl8723be 驱动 就完成了。
遗留问题:自动升级内核后,重启系统该wifi驱动会失效,需要重新安装wifi驱动.
dkms方式安装rtl8723be wifi 驱动:
我们可以这样利用dkms自动更新和升级内核都不需要reinstall wifi driver.
先需要安装dkms
sudo apt install dkms
1 git 下载rtlwifi_new
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
2 拷贝rtlwifi_new到/usr/src/ 目录下
sudo cp -R rtlwifi_new/ /usr/src/
3 dkms add
cmd@TR:/usr/src$ sudo dkms add ./rtlwifi_new
Creating symlink /var/lib/dkms/rtlwifi-new/0.6/source ->/usr/src/rtlwifi-new-0.6
DKMS: add completed.
4 dkms install
cmd@TR:/usr/src$ sudo dkms install rtlwifi-new/0.6
