I have HP i3 laptop and I recently install Ubuntu 16.04 LTS and I could not detect my home wifi. Later I found out that the wifi gets connected only if Im like a feet near the router. It does not work even 5 feet away, where in windows 7 (dual boot) it works even 12-15 feet away. Please help me fix this. I tried every solution given in similar posts. But nothing worked.

I found the solution for this

open terminal and run 

iwconfig

Note down the wlp number, in my case it was wlp13s0

Now download the driver from this link

And unzip and copy it to the Desktop. The final result should be like you should have a folder named rtlwifi_new-rock.new_btcoex in Desktop.

Now go back to terminal and cd to that folder. that is 

cd Desktop
cd rtlwifi_new-rock.new_btcoex

Now run these commands 1 by 1 

make
sudo make install
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2

By now your wifi should be strong and start working, but follow below commands to make the settings permanent

sudo ip link set wlp13s0 up
sudo iw dev wlp13s0 scan
echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf

This should fix the wifi and no reboot required.
