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 )

Step 1.

Step 2.

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.

I have also tried deleting the stored wifi adapter.

Step 1.

Step 2.

But it comes back again after restarting. Please help.

EDIT

Just now I used WirelessKeyView and it shows the old password of my wifi. That means it is somewhere stored. How to delete/change that?

  • @idavid Wireless card? You mean this: Broadcom netlink(TM) Gigabit ethernet or may be this one Intel(R) Centrino(R) Wireless-N 1000. I got these in Device Manager. By the way, my laptop is Lenovo Y470. Wireless card or anything is not changed yet.

As iDavid suggested, this problem was because of Intel software. Instead of uninstalling it I simply deleted my wifi entry from this software, and Now it is working fine.

I had the same problem with a TrendNet wifi card in a desktop. The TrendNet software was saving a profile for the Wifi network that it was passing along to Windows 7, along with an out-dated password.

Once I removed the Wifi network's profile in the TrendNet software and then re-joined the Wifi network through the Windows 7 interface the new password was used from that point on.
