ubuntu18.04 用dkms安裝wifi驅(qū)動(dòng)rtl8723be

整理下在ubuntu論壇安裝wifi驅(qū)動(dòng)的累積心得

常規(guī)方式安裝 rtl8723be wifi 驅(qū)動(dòng):

問題:自動(dòng)升級(jí)內(nèi)核后,重啟系統(tǒng)該wifi驅(qū)動(dòng)會(huì)失效,需要重新安裝.

ubuntu18.04 正確安裝rtl8723be驅(qū)動(dòng)步驟:

1 先安裝好需要編譯的東西
sudo apt-get install linux-headers-generic linux-headers-$(uname -r) gcc g++ build-essential git 

2 cd切換到需要放rtlwifi_new 到目錄下 佃迄，再執(zhí)行
git clone http://github.com/lwfinger/rtlwifi_new.git

3 先停止網(wǎng)路
sudo service network-manager stop

如果不是首次安裝該驅(qū)動(dòng),在第3步后執(zhí)行
$ sudo modprobe -rfv rtl8723be
刪除卸載老的無線網(wǎng)卡驅(qū)動(dòng)

4 cd 到 rtlwifi_new 目錄下執(zhí)行
sudo make
sudo make install
sudo modprobe -v rtl8723be fwlps=0 ips=0

5 重啟
sudo reboot 

6 確認(rèn)是否關(guān)閉 fwlps=N ips=N
systool -v -m rtl8723be

如果查看 fwlps=Y ips=Y 的話就 
echo "options rtl8723be ips=0 fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf

這樣首次安裝rtl8723be 驅(qū)動(dòng) 就完成了踢代。

遺留問題:自動(dòng)升級(jí)內(nèi)核后,重啟系統(tǒng)該wifi驅(qū)動(dòng)會(huì)失效,需要重新安裝wifi驅(qū)動(dòng).

dkms方式安裝rtl8723be wifi 驅(qū)動(dòng):

我們可以這樣利用dkms自動(dòng)更新和升級(jí)內(nèi)核都不需要reinstall wifi driver.

先需要安裝dkms
sudo apt install dkms 
1  git 下載rtlwifi_new
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git

2 拷貝rtlwifi_new到/usr/src/ 目錄下
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
