My "Manage Wireless Networks" window lists all the wireless networks I have settings for, but the details are not visible - it looks as follows: As you can see, the details for the network are visible in the status-bar, but I don't want to select each listbox item to know what network that might be... Any ideas what might be causing this and how I could fix it would be appreciated...Ernst, C# MVP (South Africa)

Hi, I would like to share you the following article to troubleshoot the issue. You can rename the Usrclass.dat file to resolve the issue. Manage wireless networks has no listings Thanks, Novak

Thanks, I'll give that a try. FWIW, on Windows 7 that file is located at: <drive>\Users\<username>\AppData\Local\Microsoft\WindowsErnst, C# MVP (South Africa)

OK. If there is any update, please feel free to let me know. Regards, Novak

This file is always locked, and I can't rename it.Ernst, C# MVP (South Africa)

In Windows 7, the file can be located in the following path: C:\Users\User name\AppData\Local\Microsoft\Windows If the file cannot be renamed, please right click the file and click Properties, and then add your account to the Security tab so that you have enough permission to modify it. If it does not work, please restart the machine in Safe Mode and take ownership of the whole folder to modify the file for a test. Thanks, Novak
