Only when I'm closer to the router, it shows any signal, but when I'm just little far from it, it is not showing wifi routers signals.

I mean physical access, is it easy to replace? Some HP laptops require major disassembly to get to the wifi card– Jeremy31Jan 6, 2016 at 23:40

With Ubuntu 16.04 and later, go to Parameter settings as nothing needs to be downloaded
Progress from Larry Finger from here
If you installed rtlwifi-new-dkms from Pilot6's PPA, it will need to be removed with
sudo apt-get remove rtlwifi-new-dkms
Reboot, then
sudo apt-get install git build-essential
git clone https://github.com/lwfinger/rtlwifi_new
cd rtlwifi_new
make
sudo make install
Reboot and then
Parameter Setting
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=1
Test wireless, if no change then
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
Test wireless again, one or the other should result in better reception
When you find that one works better than the other
echo "options rtl8723be ant_sel=X" | sudo tee /etc/modprobe.d/rtlbtcoex.conf
Where X
is 1 or 2- whatever resulted in better performance, in the case of Swapnil Sharma it would be
echo "options rtl8723be ant_sel=1" | sudo tee /etc/modprobe.d/rtlbtcoex.conf
Then the parameter will be remembered following a restart

1Thanks it works. But not Completely. I have to use this again and again after restarting my Laptop.
sudo modprobe -rv rtl8723be sudo modprobe -v rtl8723be ant_sel=1

WOW... This actually works... seems to have worked for my Realtek RTL8188EE WiFi driver. Thank you so much @Jeremy31 ! This issue was really starting to bother me. Mar 20, 2018 at 14:00

Hi This worked fine. I faced this issue with Ubuntu 18.04 a few months back and at the time I had copied the new rtlwifi drivers from this link : github.com/lwfinger/rtlwifi_new After upgrading to Ubuntu 20.04, I started facing this again. This time i just checked if I needed to download the drivers again and found the link is not working. But luckily I ran the command without downloading the drivers and it worked like a charm. So all in all method is working but link is not available anymore. if Any of you has the repo for these drivers, please post it here. Cheers– HarshilAug 1, 2020 at 9:04
