Hi @PaintGal 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you're encountering an issue with your internet connection due to proxy and firewall settings. Even though your Wi-Fi is connected, the proxy and firewall might be blocking your access to the internet. Let's go through some simple steps to help you fix this issue.

1. Check Proxy Settings

A proxy is an intermediary server that can be used to filter or route traffic, and sometimes it can cause issues if incorrectly configured. Here's how to disable the proxy:

1. Open the Settings: Press the Windows key + I to open the Settings app.
2. Go to Network & Internet: Click on Network & Internet.
3. Proxy Settings: In the left menu, click on Proxy.
4. Disable Proxy: Under Manual proxy setup, make sure the Use a proxy server option is turned off.
5. If it's already off, try toggling it to on, saving, then back to off again.

Note: Some networks, especially business or school networks, might require a proxy for internet access. But if you're on a home network, you usually don’t need a proxy.

2. Check Firewall Settings

The firewall might be blocking your internet connection. To check and adjust your firewall settings:

Open Windows Security: Press the Windows key and type Windows Security, then press Enter.

Firewall & Network Protection: In the Windows Security window, click on Firewall & Network Protection.

Allow an App Through Firewall:

• Click on Allow an app through firewall.
• Check if your web browser (such as Google Chrome or Microsoft Edge) is listed and allowed to communicate through the firewall.
• If your browser is not listed, click on Change settings and Allow another app, then find your browser and add it.

Reset Windows Firewall: If you suspect the firewall settings might be causing issues, you can reset the firewall to its default settings:

• Open the Start Menu and type Control Panel.
• In the Control Panel, go to System and Security and then Windows Defender Firewall.
• On the left, click Restore defaults and follow the instructions to reset your firewall.

3. Flush DNS Cache

Sometimes clearing the DNS cache can resolve internet connectivity issues:

1. Open Command Prompt: Press the Windows key, type Command Prompt, right-click it, and select Run as administrator.
2. Flush DNS: In the Command Prompt window, type the following command and press Enter: ipconfig /flushdns
3. After it completes, restart your computer and try accessing the internet again.

4. Reset Network Settings

If your network settings have become corrupted or misconfigured, resetting them might help:

1. Open Settings: Press the Windows key + I to open Settings.
2. Go to Network & Internet: Click Network & Internet.
3. Network Reset: Scroll down to the bottom and click on Network Reset.
4. Reset Now: Click Reset now and follow the on-screen instructions. This will reset all network-related settings to their default values.
5. After resetting, you will need to reconnect to your Wi-Fi network.

I hope this helps.

Take care and have a good day.
