Windows 7: Unable to detect WiFi networks after reinstalling Windows 7

Unable to detect WiFi networks after reinstalling Windows 7

I reinstalled Windows 7 on a Samsung Series 5 (5 months old) and now I cannot connect to (or even detect) any WiFi networks.

I am currently in an active WiFi environment (confirmed) that I used many times in the past, but when I click "Connect to a network" I get:

"No connections are available."

If I select the "Troubleshoot" option, I get: "Troubleshooting couldn't identify the problem"

Prior to the reinstallation, a list of nearby WiFi options would appear and I would access the public option.

Basically, the computer is no longer detecting local WiFi networks.

I won't be surprised if this is something rather basic...

Thanks.

Is your wifi turned on? Fn+F12 should turn it off or on.

Update the driver using Samsung Easy Software Manager

Nothing appears to happen when I press Fn+F12.

1) No screen message (indicated I just turned WiFi on or off)

2) Still get the "Not connected / No connections are available' message when I select 'Connect to a network' (previously a list of WiFi networks would appear)

I will try the driver update per your suggestion.

I think my Samsung Easy Software Manager might be lost. (?)

I reinstalled Windows 7 using the CD that came with the notebook ("System Recovery Media Windows 7 Home Premium SP1 For Distribution Only With a New Samsung PC").

I assumed (yes, I know...) that since it was a Samsung-specific CD, that it would reinstall the notebook to the state when I purchased it.

However, the install appears to have been a generic Windows 7 version, as a number of the folders that were originally on the desktop are no longer there. And I cannot locate the Samsung Easy Software Manager. Or Samsung anything for that matter.

Still in WiFi limbo.

Download and install . Had an issue uploading it here so I had to upload it somewhere else

Downloaded and installed WLAN driver from Samsung site.

Downloaded and installed Easy Settings 1.1.1.6

When I open Easy Settings, I can select Boot Management, General, Power Management, Display and Desktop Background / Screen Saver with no problem.

However, when I select "Wireless Network", I get: "Easy Settings has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

But Windows does not close the program or notify me -- it continues to search for something in an endless loop.

Also, when I select Fn+F12, there is no indication on the screen of any change. Should a Wireless LAN ON message appear?

I will leave my WiFi connection shortly, but may be able to check later for additional advise / suggestions via a dial-up connection (please don't say anything :-), but hope to return to a WiFi connection tomorrow to continue the effort to identify and fix this problem.

Thanks.

The s/n command worked fine: HU4Z91FC600392

The model command did not, but it was easy to get it off the bottom of the computer: NP535U3C-A01CA
