Unless we know the model number we can’t help with your specific model, but there are a few things you can try now if possible.
The first thing I would do in this case is try the drivers and see if that helps. Download them on another machine - or Ethernet and then remove and reinstall the driver. I would download it from the wireless card manufacturer and HP if possible, depending on if the card has drivers direct from the manufacturer - some of the Intel cards like the 6235 do not have drivers directly from Intel, but others like the 7260AC do for example. HP usually uses Intel in their higher end business laptops, so it may very well be Intel unless you bought one of the cheap configurations. Consumer machines (and some low end ProBooks) use Ralink (purchased for IP by an SoC manufacturer. Most cards are EOL and struggle in Windows 10) or Realtek (may find drivers on manufacturer website).
If that doesn’t work, you will need the service manual to find out which cards are on your WLAN WL since pre-2013 HP Business machines prior to the Haswell EliteBook series are infamously known for having a wireless card whitelist under the FCC excuse, when it’s really to protect HP’s parts sales. The issue is their Business BIOSes have been signed with a checksum for years and verified, but 2010+ is ALL RSA signed and the machines verify the RSA signature against the “validated” private key. It’s the reason I can’t modify the nc6000 BIOS to nuke the WL from orbit entirely, and you’re stuck dealing with this parts sales protecting whitelist :(. ALWAYS BUY A MID SPEC MODEL WITH HP BUSINESS to get the Intel wireless as an FYI - even Haswell EliteBooks just in case. This isn’t like a lower end Dell where it can come with a DW1506 (AR9485) or a BCM based card like the DW1501 (BCM4313). I can buy a NOS Intel 7260AC (or a used Intel 6235) and get better wireless with little trouble.
I’m not sure about the WWAN situation with HP on Haswell EliteBooks, but chances are it’s still there due to more real FCC issues and carrier demands for network security.
