Windows 7 Access denied all of a sudden

It sounds like your computer is facing some issues with connecting to a specific wireless network, which is causing you to receive the message about additional login information being required. This additional login information might be needed by the network for authentication or authorization purposes. Here are a few steps you can take to troubleshoot and address this issue: 1. Restart Your Computer and Router: - Sometimes, a simple restart can fix connectivity issues. Try restarting both your computer and the wireless router. 2. Forget and Reconnect to the Network: - Forget the problematic network from your list of saved networks and then reconnect to it. This can help resolve any authentication issues. 3. Check Network Settings: - Ensure that your network settings are correct. Sometimes, changes in settings can cause connection problems. 4. Update Network Drivers: - Make sure your network adapter drivers are up to date. Outdated drivers can sometimes lead to connectivity issues. 5. Check Firewall and Antivirus Software: - Your firewall or antivirus software might be blocking the network connection. Temporarily disable them to see if it resolves the problem. 6. Reset Network Configurations: - You can try resetting the network settings on your computer to default. This can sometimes fix connectivity issues. 7. Contact the Network Administrator or ISP: - If you still can't connect, it's possible that the network may require additional steps for authentication. Contact the network administrator for assistance. If none of these steps resolve the issue, it might be specific to the network you are trying to connect to. The network settings or security protocols might have changed, requiring additional information for authentication. If you encounter any specific error messages or codes during this process, please provide them for more targeted assistance.
