Windows 7 reverts back to old wireless profile on reboot,restart,wake

Windows 7 continues to revert back to the old wireless profile despite me deleting all old wireless profiles.

• Wireless adapter is Edimax EW-7128g, newest drivers for Windows 7 64bit
• First set up a WEP profile the usual manner by connecting using the bottom-right wireless networking widget; "Save this connection", yes.
• Works right off the bat, first time
• Needed to switch to WPA on router for better security. Same router. Done. Entered new credentials using the same wireless networking widget. Works fine first time, right off the bat.
• Computer enters sleep mode overnight.
• Upon a wake (or restart, or cold boot) - Windows 7 reverts back to the old WEP profile.
• I go into "Manage Wireless Networks" I select the profile from the list, hit DELETE. Removes it from the list. ADD new profile, supply proper WPA credentials, "Save this connection". Works fine. Manage wireless networks displays proper information (WPA security)
• Restart, or reboot, or logoff. BOOM. Back to using the old WEP profile!!!
• Tried this using Administrator account and user account. Same behavior.
• Workaround is to change the security type / credentials or delete & create a new profile every time windows is rebooted/logoff/restart.

I cannot for the life of me figure this out. I am not using the vendor's connection utility. Windows cannot remember the new connection profile and despite me deleting the old one ... continues to revert back to it.

Any ideas?

Try to manually create a new network connection from the start instead of trying to mod the old profile. I did this just last week and it worked for me.

Create or modify network profiles

If the network that you want to create a profile for is not in the list, click Set up a connection or network, click Manually connect to a wireless network, click Next, and then follow the instructions. If you save the network, a profile for the network will be created and stored on your computer. To select specific authentication and security settings, click Change connection settings.

Already tried deleting the old profile.

I delete the old profile, create a new profile with WPA.

Connects using WPA security fine.

Reboot, restart, or wake the PC ... back to the old WEP profile. Its like there's a ghost in the machine that won't let go!

It certainly works for me because I just did this last week on a new machine. I can't imagine what might be causing this but it's not normal behavior. I can't find any references to a similar problem.

Although I have noticed that when I delate a Users-PC from the credential manger that it comes back right away. This doesn't cause any problems for me and it's same for everyone else with no way to fix it as yet.

I'll keep looking around for a fix but I can't help but to think there is an underlying problem involved in your case.

You might try typing sfc /scannow into your command prompt run as admin and see if it finds any file integrity problems that might cause this problem to occur.

Adam, did you ever find a a way around your issue? I have just run into the same thing with my gateway laptop. I changed my router security from WEP to WPA2-AES. I had no issue changing the settings in Win 7 and was able to connect right away. However, if I do a shutdown/restart cycle the settings are lost. More than that, I had 2 wireless network profiles. I removed one profile that I no loger use. When I shutdown/restart, not only have I lost the WPA2 settings, the "deleted" wireless profile is back and I Norton Antivirus thinks it has not been updated. It appears windows is going back to an old restore point.

I would be very interested in learning what you did to get rid of the issue.

Thanks
