not detecting any wifi network but detects mobile hotspot

I suggest that for diagnostic purposes you follow https://help.ubuntu.com/community/WirelessTroubleshootingProcedure

I have tried but still It's not working.

The wireless troubleshooting procedure is not supposed to solve your problem, but it will collect diagnostic information that might help identifying the cause of your problem.
Please copy/paste all output into this question document.

ok, the firmware files seem to be correctly available.
I suggest trying something different:

Try changing the configuration of the driver:

Issue the command
echo "options rtl8723be swenc=1 fwlps=0 ips=0 ant_sel=1" | sudo tee /etc/modprobe.d/rtl8723be_options.conf
and restart the system.

If this does not help, issue the command
echo "options rtl8723be swenc=1 fwlps=0 ips=0 ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be_options.conf
and restart the system.

If this does not help, but creates problems, you can undo these changes with the command
sudo rm /etc/modprobe.d/rtl8723be_options.conf
and a reboot.

I have tried but it's not working.

"it's not working"

Not working in what sense? Details please!

What is the output of the commands

iwconfig
sudo iwlist scan | grep -Ei 'chan|ssid'

1) iwconfig :-

vmnet1 no wireless extensions.

vmnet8 no wireless extensions.

enp7s0 no wireless extensions.

wlp13s0 IEEE 802.11 ESSID:off/any
          Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
          Retry short limit:7 RTS thr=2347 B Fragment thr:off
          Power Management:off

lo no wireless extensions.

2) sudo iwlist scan | grep -Ei 'chan|ssid'

vmnet1 Interface doesn't support scanning.

vmnet8 Interface doesn't support scanning.

lo Interface doesn't support scanning.

enp7s0 Interface doesn't support scanning.

for diagnostic purposes please re-run https://help.ubuntu.com/community/WirelessTroubleshootingProcedure and copy/paste all output into this question document.

Wifi working but it work if router/mobile is near to laptop. Look like it detect only nearby wifi around 3 ft distance area.

Have you tried setting the option for ant_sel as described in comment #11?

Yes I have tried . But it's detect only nearest wifi.

Have you rebooted after changing the options?
What is the current output of the commands

cat /etc/modprobe.d/rtl8723be_options.conf
grep -i rtl8723be /etc/modprobe.conf /etc/modprobe.d/*.conf

And - as already written in comment #15 - It could help to see the current output of the wireless troubleshooting procedure.
