我昨天刚刚在我的联想 E520 上安装了 Ubuntu 18.04.1，我遇到了这个问题，因为我尝试连接 WiFi，WiFi 连接正常，但过了一段时间（有时是几分钟，有时是几秒钟）连接就断开了！我搜索了这个问题，发现当我rfkill list all在终端中输入时，我得到了这个：
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: tpacpi_bluetooth_sw: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
我意识到它们全都是“否”，但正如你所见，“无线局域网”是“是”，我试图通过输入以下内容将其改为“否”，sudo rfkill unblock all但它只起作用了几分钟，然后又变回“是”！我不知道该怎么办
这是我的 lspci 输出：

经过长时间的搜索和询问，我的问题终于通过修复互联网上的 DNS 得到解决。以下是解决方案：
首先将此代码保存为桌面上的 .sh 文件（这是一个 DNS 修复程序文件）（您可以随意命名该文件）：
#!/bin/bash
##start Local net Cheking
var1=`ip addr | grep brd | wc -l`
var2=`ip addr | awk {'print $1'} | grep : | wc -l`
if [ "$var1" == "$var2" ];then
echo -e "\033[91m[-]Your Are Offline!!!"
exit 1
else
echo -e "\033[92m[+]Your Local Netowkr Is Ok!."
##start internet Checking
ping -c2 -w2 8.8.8.8 1>/dev/null 2>/dev/null
if [ "$?" != "0" ];then
echo -e "\033[91m[-]You Have Internet ERROR! CHECK THAT."
exit 1
else
echo -e "\033[92m[+]Your Internet Is OK!"
##Start DNS Checking
nslookup gnu.org -timeout=1 1>/dev/null 2>/dev/null
if [ "$?" != "0" ];then
echo -e "\033[91m[-]You Have Dns ERROR! "
read -p "I cat To Ok That, Do You Want To Contniue?[Y/n] " yesorno
if [ "$yesorno" == "Y" ] || [ "$yesorno" == "y" ] || [ "$yesorno" ==
"" ];then
echo -e "nameserver 208.67.222.222\nnameserver 8.8.8.8" | sudo tee
/etc/resolvconf/resolv.conf.d/tail 1>/dev/null
sudo systemctl restart NetworkManager
else
echo "Ok, You Need To Fix it."
exit 1
fi
else
echo -e "\033[92m[+]Your DNS Is OK!"
exit 0
fi
##End Of DNS Checking.
fi
##End of internet checking
fi
##End Of Localnet checking
然后打开终端，一步步按照下面的代码操作：
cd Desktop
chmod +x FileName.sh
./FileName
reboot
希望对你有帮助
