Cannot use WiFi

[JleChen]

My desktop has no wireless icon, no wireless adapter driver shown under Device Manager. There were no such problems before. What is wrong?

Hi

"There were no such problems before. What is wrong?"

Before it failed? There wouldn't be.  It's broken.

So as it's a  HP ENVY 700-210xt CTO Desktop PC you can quickly and easily see if the WiFi adapter is still in place.

Re-Seat it please.

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

NOW begin checking/testing/proving the Hardware is fit for purpose.

Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

If in doubt please ask.

Hi

NO  ( disconnect all externally connected).

Just test it.

I installed HP PC Hardware Diagnostic tool, but unfortunately even no such a type like "Wireless Module Test" is existing on my PC. What is the problem?

Thanks.
