I have the Realtek rtl8723be driver on my HP-Pavillion Notebook.

While installing Ubuntu 18.04 LTS through plug-n-play option, I tried the following commands before actual installation:

sudo modprobe -r rtl8723be
sudo modprobe rtl8723be ant_sel=2

and the wifi was working just fine.

But after installation alongside Windows 10, somehow the wifi stopped working properly, and now only wifi networks very close to the device appear.

I tried installing realtek software from here on GitHub as mentioned in the README. But still no progress.

I even tried changing ant_sel parameters, then saving them to my /etc/modprobe.d/rtl8723be.conf and then performing a cold boot. But still no progress.

I also tried installing from this branch, but I got errors.

This question is duplicate of this question. I am running 18.04 and having same problems as that of the linked question that is my hotspot created by linux gives very slow internet speed on my mobile. The linked question did not have any answer that's why I am asking this question again. I have ethernet connection which provides 80Mbps download speed. Also hotspot created using Windows provides better speed.

Please do not downvote this question. Either ask me to delete it or edit it accordingly.

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:

What can I do? I am fairly new with Ubuntu.

I have tried this answer, but it says "Unable to locate package rtlwifi-new-dkms"

I am using HP Pavilion. The wifi switches off and the Airplane mode is switched ON after a suspend. It prompts me to use the Hardware Switch to disable it. But that does not work.

From what I have observed, after this happens, even if I plug in an external wifi adapter, it refuses to work! I don't believe the issue has something to do with Wifi per se, but a deeper rooted problem

This is a common issue that I have looked over in the internet. None of the solutions have worked for me. List of solutions I've tried:

  • /etc/init.d/network-manager restart
  • service network-manager restart
  • sudo systemctl restart network-manager.service
  • rfkill unblock all
  • sudo rfkill list

This produced:

  • I also tried re-installing the drivers :(

"No wifi adapter found" in settings - screenshot

I have attached the output of this command wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \ chmod +x wireless-info && \ ./wireless-info

https://www12.zippyshare.com/v/gBZnOz7G/file.html

This has become increasingly difficult to work with. Any help is appreciated. Thanks in advance :)
