I am using dual boot of Windows 10 and Ubuntu 18.04.

Wifi networks are not showing in Ubuntu but it is working fine in Windows 10. It is unable to detect wifi networks on Ubuntu. When I make the hotspot then it shows only that network but it is unable to show all the available networks which can be easily shown on Windows 10.
After running this script, I got the report:- https://paste.ubuntu.com/p/qBfbFszrv6/plain/
When I give command dmesg, I got error as "rtlwifi: AP off, try to reconnect now" Is this a problem ?
When I give command ispci then I got this result
Please help.
Please find the attachments regarding the problem:

We notice that the signal strength is quite low, 30/70, and that you are only able to scan and see one network, yours.

wlo1      Scan completed :
          Cell 01 - Address: <MAC 'Redmi' [AC1]>
                    Channel:6
                    Frequency:2.437 GHz (Channel 6)
                    Quality=30/70  Signal level=-80 dBm  
                    Encryption key:on
                    ESSID:"Redmi"
                    <snip>

Let's force the driver to use antenna #2 to see if it helps:

sudo modprobe -r rtl8723be
sudo modprobe rtl8723be ant_sel=2

Is there any improvement? Check:

sudo iwlist wlo1 scan

If not, please retry the above sequence but with ant_sel=1 and scan again. One of the two will produce an increase in signal strength and stability. Whichever it is, make it permanent with:

sudo -i
echo "options rtl8723be ant_sel=2"  >  /etc/modprobe.d/rtl8723be.conf
exit

Of course, use =1 or =2, whichever gives the best result.
