Clear wi fi internet

How can I clear out all old Wi-fi settings on Windows 7?

I watched Wi-Fi Protected Setup (WPS) in Windows 7 on Channel 9 and would love to test it out. But my laptop is already set up. In the video one of the guys go into the command prompt and runs some command starting with netsh , but then zooms out so you don’t get to see the rest of what he writes. Does anyone know what he writes there to make his laptop completely forget about the Wi-Fi settings he just set up?

If you open the Network and Sharing Center, then click on «Manage wireless networks» you can remove all saved wireless network profiles.

That seemed to work 🙂 But didn’t get the new Wi-Fi connect dialog though. maybe it is something that has been done after the RC and will be in the final release.

this doesn’t answer the question about the command used, and in some cases (ie. you are not admin) this answer also doesn’t work.

I think it’s probably the Delete command:

netsh wlan delete profile name="ProfileName" 

Where ProfileName is the name of the profile you set while creating the connection—which you can find using the List command:

when I start netsh, and then type delete and press enter, I get «delete helper — Removes a helper DLL.» Doesn’t seem right.

you have to be in the wlan section I believe. when you start netsh, you then type wlan and it takes you to the wlan interface section which has different commands.

Open CMD as Admin and run the following command:

netsh wlan delete profile name=*

I had an SSID I couldn’t make go away. I tried refreshing the available connections list, turning the radio off and on, resetting the cable modem, the netsh commands mentioned in another answer, searching the Registry for the SSID and deleting all of the associated keys — none of that worked. I was finally able to make it go away by disabling the wireless profile, then using the network troubleshooter to re-enable it (because «Disable» never changed to «Enable»). When the connection list came back up, the offending SSID was finally gone.
