PhilANZ: My warranty was one year only.
CGA will ensure its ACTUAL warranty will be considerably longer than that .
Mention the GCA & try to get it fixed under warranty.
Otherwise , you need to see if its a software or hardware fault.
Thats were it gets a bit tricker, either a bootable CD (Linux etc) or wipe & load Win7 as a test, or re-image back to
as it was when you bought it (if you have that option)
Some HP's have built in hardware testing (you get to those test menus at startup) , not sure if those tests will test wifi though
PhilANZ: I've now learned that wat I thought was a great service by HP is now worse than useless in that I thought all was well since the HP support tool told me so - but it's not. So I won't fall for that again. Always go to the manufacturers site. My card is an Intel AC 8260.
It's take me a while. First had to find the button driver. Then I had problems installing it. Finally removed it, rebooted and re-installed to make sure it used the latest. It seemed to fix it - but having learned the lesson from yesterday, shut down.
No WIFI - turn on manually it again turns off.
Yeah, unfortunately you cannot trust any of those support software applications that are supplied by laptop manufacturers.
My suggestion is to get the HP UEFI tools downloaded and installed. This will greatly improve the F2 tools at bootup (start the laptop and press F2 until the menu appears)
This will allow you to test the WiFi controller to ensure the BIOS can see it properly. If that test passes OK, then you know the hardware is OK and the issue is either with the OS or the drivers in the OS.
You mention that the hardware is Intel? I strongly suggest going to the Intel site and getting the latest Windows drivers for the card. Intel normally package up a whole bunch into one .exe so that makes it easy. I have found that Intel will release drivers after HP stops customizing the installer so there is a chance there is a newer version out there.
And if all the above fails, and you have access to one, try another WiFi module in the laptop.
I have seen similar with colleagues laptops ... usually fixed by checking the Power settings particularly turn off the "Allow computer to turn of this device ...".
Also ensure full power for both mains and battery (although the battery setting often causes weird problems).
I will look into the UEFI tools. And thanks for the tip re the Intel site - hadn't thought of seeing what they've got. I tend to think two years isn't very old - but I forget we're talking computer years.
Yeah 2 years is pretty old for Intel drivers. I have seen multiple issues with RADIUS clients and older WiFi drivers. I think the latest ones i have seen are dates Jan 2018 (although that might not be the same for your card) but at very least the drivers should be 2017
Sometimes the quickest option is using a cheap USB wifi dongle.
Otherwise it could be many more hours doing software & hardware fault finding.
I have similar issues with a Dell and the built-in Intel AC-7260. It's always a complete mongrel dog of a wireless adaptor. Sometimes it just refuses to connect to previously configured WiFi APs. Then a few weeks ago it started becoming DISABLED (or is that "differently-abled in today's PC world?) in DEVICE MANAGER at random times until a reboot - you couldn't ENABLE it . Toggling the switch didn't make any difference either.
It hasn't done it for about a week now. It's always been configured for maximum performance (no sleep).
If it starts playing up too regularly I'll just get a USB one. It's usually on a dock these days though so I could ethernet it without any inconvenience but then there's the problem of when it's not on the usual WiFi AP - whether it'll connect or not is a gamble.
I had an issue with an HP consumer notebook where either the Wi-Fi adapter would connect for only a few seconds (server log showed successful DHCP negotiation) then disappear or would not appear in the list of devices at all. Resolved by re-seating the Wi-Fi card in its slot.
Might be worth a shot, the WLAN slot is easily accessible on a Probook.
Sorry to hear that problem persists .... I appreciate that you have looked at the HP web site for drivers, but personally I'd try uninstalling the wifi drivers, then reboot and see what Windows itself brings in.
I have sometimes seen devices perform better with Win installs, whereas so-called manufacturer updates have subsequently caused problems.
Nothing to lose by trying anyway
