I am having issue with HP notebook laptop with Ubuntu 18.04 installed. It is not detecting any WiFi signal. Looks like driver issue. Tried to find driver on HP website but did not get it. How do I find and install third party driver?

lspci -knn | grep Net

  • We need more info. Please help us help you by doing lspci | grep -i wireless && sudo dmidecode -s baseboard-product-name && sudo dmidecode -s baseboard-manufacturer && sudo lshw | grep product | head -n1 && lshw | grep -v "loop" && lsb_release -a and paste the result into your question after clicking edit. Please do not click on Add Comment as new comments can shove old comments off screen; your information about your PC and the Ubuntu installation should all go in the Question so we can all see your findings.

    @K7AAY re: "Please do not click on Add Comment as new comments can shove old comments off screen". This is incorrect.

    @heynnema, would you please be so kind as to look at comments for askubuntu.com/questions/1157538/… which is just one example. Six comments are shoved off the screen there.

    @K7AAY they are displayed if you just click the "show 6 more comments" link, and then all comments are visible. Also, you use your "canned" comment almost everywhere, and I'm not sure that the commands that you request are really required info as it applies to the question. Like "dmidecode -s baseboard-product-name && sudo dmidecode -s baseboard-manufacturer". Why?
