    Try to connect to wifi again and run this in terminal
    Code:
    ./wireless-info
    Then connect with the smart phone and post results

    Can you change the wifi router to use channel 1 rather than auto or channel 9?
    It might also help to go into Network Manager settings for your connection and disable IPv6, and set your country code, in terminal do
    Code:
    sudo iw reg set IN

    Hello @jeremy31, I have changed the channel to 1 and have disabled the IPv6 from network settings(GUI) even set the country via terminal. After this an improvement has noticed the connection gets dropped but but now it regains as soon as I turned the wifi Off and then On. The speed of wifi has become somewhat slow here is the link of wireless txt after these modifications https://pastebin.com/YSg3CAB7

    No, it will not.

    Your device is this: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]

    The modalias for the driver you've linked is but a single device:
    Code:
    version:        v4.3.23.6_20964.20170110
    author:         Realtek Semiconductor Corp.
    description:    Realtek Wireless Lan Driver
    license:        GPL
    firmware:       rtlwifi/rtl8188fufw.bin
    srcversion:     41F856D51474AE9E736D905
    alias:          usb:v0BDApF179d*dc*dsc*dp*icFFiscFFipFFin*
    This is a completely different driver for a completely different device.

    In this context, AP refers to Access Point; that is, your router. Could this be a router problem? Could your router be working intermittently? Do other compters on the network ever disconnect and reconnect?

    In my experience, Windows and iOS wireless device and driver combinations seem to recover from such things gracefully. Many Linux drivers do not.
