I have 250mbps download speed at 5Ghz. This computer does not recognize 5Ghz wifi signals, only 2.4. With my Surface pad next to my HP I get well over 200mbps. The HP only seeing 2.4 gives me 30mbps. I've done the trouble shooting protocols from both HP and Microsoft to no avail. I can find no switch in any of the menus where I can turn on 5Ghz. I can't believe that this computer has no 5Ghz by design. Or is it so?

Go to the device manager and click to expand the Network Adapters device manager category.
There you will find the name and model number of the wireless network adapter.
If the suffix of the model ends in b/g/n, it is a single band (2.4 GHz) wireless network adapter.
if the suffix ends in a/b/g/n or a/g/n, it is a dual band wireless network adapter.
Dual band wireless cards pick up the 5.0 GHz band automatically.

You're very welcome.
The easiest thing to do to add dual band wireless to your PC, would be to purchase a dual band external usb wireless network adapter.
There is no driver that will add 5.0 GHz networking to the current wifi card.
It is a hardware limitation, not a software/driver one.
