.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I installed Ubuntu 18.04.1 LTS on my Haier Y11B laptop. But after installing my WiFi works sometimes or sometimes it don't work. Sometimes it shows all the WiFi network available around me and allows me to connect. But after sometime it lose its signal strength and don't shows any WiFi connection at all or shows very week signal which is unable to connect. Even if I keep it near the WiFi router signal strength is same. But when i uses the Windows or uses try-Ubuntu option my WiFi works 100% fine.
I tried restarting network manager by running sudo service network-manager restart. But most of the times it also don't works.
Plz find my Wireless Cards info below
qasim@Haier-Y11B:~$ sudo lshw -class network

I had the same problem!
I solved it by creating an executable file (* .sh) with the following codes:
sudo /etc/init.d/dns-clean restart
sudo /etc/init.d/networking force-reload
sudo /etc/init.d/nscd restart
----- copy code in an empty file ----
#!/bin/bash
# NB: **First install nscd** with sudo apt-get install nscd
# run this command to flush dns cache:
sudo /etc/init.d/dns-clean restart
# or use:
sudo /etc/init.d/networking force-reload
# Flush nscd dns cache:
sudo /etc/init.d/nscd restart
# If you wanted to refresh your settings you could disable and then run
sudo service network-manager restart
echo "DNS Flushed!";
---- save as something.sh ----
Execute your bash file in terminal with:
chmod +x /path/to/your/something.sh
./path/to/your/something.sh

It is better not to put sudo inside the script. Then runsudo ./path/to/your/something.sh.
