Remove Old Wireless Profile

You travel to hotels, stay at RV parks, go to meetings, visit families, etc. and use their Wi-Fi networks to do your Internet stuff. Many places require users to enter an encryption key to access their Wi-Fi to get on to the Internet. This is cool.

When you re-visit a previous Wi-Fi site, you cannot connect to that same Wi-Fi network. You can see the same wireless signal showing on your laptop but failed to connect as you were able when you were there. This is not cool but this does happen. Site owners and managers generally change the wireless encryption key to assure authorized access to their Wi-Fi. Many times, the encryption key gets passed on to unauthorized and unwanted users. You can image the effect here. Ok, so, you get the new encryption key and still cannot get connected. No matter how many times you have tried, you continue to fail. Now you are stumped and frustrated.

As the encryption key gets routinely changed, the user may need to remove that wireless networks profile that no longer work. This is common. You verified your typing and perhaps rebooted your laptop. You tied again and no resolve. The user will need to remove that previous used wireless network profile containing the old encryption key and act like you have never been to that Wi-Fi network.
