No WiFi option in Ubuntu 18.04 in HP ProBook 450 G5

[Taqi_Shah]

I bought new HP ProBook 450 G5 I5 8th Gen, and install Ubuntu Ubuntu 18.04 LTS on it, and network menu does not show any option to connect to wifi, I google the issue and tried every possible solution, but no success at all.

I assume you have tried this (assuming you have the Intel 3168 chip):

There may be some parallels here:

Got exactly the same laptop and wifi is working out of the box with Ubuntu 16.04,17.10 and, 18.04

Boot on the Ubuntu USB-Live key again to see il wifi is working, if working re-install Ubuntu on your laptop.

Did you check Ubunu iso file after download with md5 key verification ?

"sudo lshw -C network" retun:

Did you check the wifi card connexions ?

Find it in the Part Locator here:

https://h20574.www2.hp.com/results.htm?SID=1009924041&MEID=9DE9DED4-E56E-4C06-BAB0-2F9B462E95EB

and also ckeck if the card is disable in Bios

download the zip file from the given link and put it somewhere in your home directory and go to the extracted folder and open terminal at that folder location and write command . (`sudo ./install` ) after few seconds your driver should be installed.
