followed by one time messages such as: 

    Feb 25 13:45:35 barjatiyarklp NetworkManager[1292]: <info>  [1708848935.5232] device (wlp3s0): state change: activated -> failed (reason 'ssid-not-found', sys-iface-state: 'managed')
    Feb 25 13:45:35 barjatiyarklp NetworkManager[1292]: <warn>  [1708848935.5249] device (wlp3s0): Activation: failed for connection 'JioFiber-c53B1_5G'

in systems with wireless card as shown in 'lspci' as: 

    03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter (rev 03)

We can solve by:

  1. Create a file named '/etc/NetworkManager/conf.d/broadcom_wl.conf' with: 
    [device]
match-device=driver:wlp3s0
wifi.scan-rand-mac-address=no
    where name wlp3s0 should be replaced with device name (Also visible in logs) before rebooting
  2. Reboot the machine and observe
    We could observe issue fixed without reboot. Reboot is suggested as a additional measure / precaution.
