No OS stated, windows 10? did you upgrade windows? (???) you mean Wifi... im sure, wireless can be 5G wireless too. so do all other things I the home work with Wifi?/? like Cell phone and TV? are you at home , work or startbucks? or air port? do you have wifi router in the home?(model#) Is it your wifi router or owned by ISP.? do you know your wifi login credentials.? how far are you from the wifi router, try at 6ft as test.? or try ethernet wired. to see if your enternet connection really work. does it even have this option? Wireless LAN 802.11a/b/g/n/ac (1x1) and Bluetooth 4.2 M.2it must be there, and show up in device manager does it? try here. click detect my drivers, to get the right ones, this PC was sold with optional wifi, not JUST ONE. use only the HP drivers OK? of still 100% HP PC use only HP drivers.
wifi is simple when it works then if not the not so simple at all. I can't see your PC nor what Wifi systems you have or distances from PC to router. not me. so lots of questions asking in the blind.
I like to test ethernet first.wired then if that works try wifi. (using the walk first the run rules of life) http://www.pcdied.com/DevMan/internet.html
