Recently I changed my wifi password ( through router ). But on my laptop ( windows 7 ) it still remembers old wifi password. It always try to connect using old password and shows Limited Access.
I tried changing it several times: ( see following snapshots )
Now at second step I change the password to correct one, and I get connected to internet. It works fine till I restart the laptop. Once restarted again same thing happens, it try to connect with old password.
