When I installed Ubuntu for the first time I had to do some work with the terminal because my Wi-Fi reception was lower than on Windows:
echo "options rtl8723be ips=0 fwlps=0 ant_sel=1" | sudo tee /etc/modprobe.d/rtl8723be.conf
After updating Ubuntu to bionic beaver my Wi-Fi randomly stops and my browser says that I am not connected to internet. I need to turn off and on my Wi-Fi to use the network.
I searched on internet and I followed instructions in this answer. Now my pc says "no Wi-Fi adapter found"
I tried doing:
sudo apt-get install --reinstall bcmwl-kernel-source
with a reboot. And I have also tried:
sudo apt remove bcmwl-kernel-source && sudo apt install git dkms
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
but nothing.
lshw -C network says that my wireless net adapter is unclaimed:
*-network UNCLAIMED

What can I do? I am fairly new with Ubuntu.
Edit:
I have tried this answer, but it says "Unable to locate package rtlwifi-new-dkms"
