After a recent update from ubuntu 19.10, I reboot my PC. After reboot, I discovered that there is no wifi-Adapter available. To install wifi Adapter manually I tried the command :
sudo lshw -C network
It produces the following output
*-network

To investigate detail about the wireless PCI I also tried the following
lspci -nnk | grep 0280 -A2
which shows,
00:14.3 Network controller [0280]: Intel Corporation Device [8086:02f0]
Subsystem: Intel Corporation Device [8086:0034]
Kernel driver in use: iwlwifi
I am in a fix what to do or how/which driver to install.
BTW, I cant not find the manufacturer of the wireless device.
