Desktop Wireless Connection GONE

[TriciaPop]

My mother has an HP TouchSmart 520. The other night, her cable went out, and her desktop lost all wireless connection. When we have the computer run diagnostics, it keeps telling us to plug in an ethernet cable. It doesn't show any wireless networks. The computer has always connected to the internet via WiFi, and we have never needed an ethernet cable. 

Do I need to reinstall wireless drivers? Not completely literate in computers, so details will help.

Thank you!

Before you get too involved in this, is the wireless at your mother's house working?   I would start with that.  It could be the wireless router got damaged when the cable went out.

BTW: just because the cable TV is working does not mean the internet came back.

Was there a storm thar caused the cable to go out or some other reason?

Hi

To supplement        TheOldMan    in his assertion.

If you use the WinKey +  R  and then type     cmd.exe pause          

you get a screen open.

The easiest test is to type 

ping 127.0.0.1

C:\>ping 127.0.0.1

the underlined bit is key

I know I do not have Ethernet connected, so the response HAS to be from my WiFi.

Please post yours.

Thanks for your reply. No, there was no storm. And I believe the router is working, as I can connect to the wireless network on my iphone.

Thanks for your reply. I will try this (or have my mother try it) later tonight or tomorrow.
