08/01/2025 (Wednesday): All machines working fine.

09/01/2025 (Thursday): Laptop couldn't access networked storage device nor internet. Yet hub knew it was connected. Disabled wi-fi and re-nabled after 'forgetting' my network and re-discovering it. Didn't work.

10/01/2025 (Friday): Connected laptop to friends network for the 1st time. Couldn't access internet until Permanently disabling BitDefender and restarting PC.

11/01/2022 (Saturday): Powered up Laptop after shutdown. Yes to BitDefender, no to internet access.

14/01/2022 (Tuesday): Searched BitDefender Community forum and found Loss of LAN/Internet with Windows 11. Posted comments on it followed step 1 & 2, with same error as before. Raised error but not sure it was sent. So raised new support call via Bitdefender Support pages.

Hello,

Can you access the internet if you disable the Firewall in Bitdefender? If yes, reactivate the Firewall and try the following:

1. Go to Network Adapters tab and set the network type to Home/Office using the drop-down menu near its name
2. Then, from the same Firewall Tab, click on Settings from the top-right , then, for the network you're currently connected to, uncheck the 'stealth mode' button to disable it.

If this doesn't help, go to Firewall → choose Rules tab → reset Rules → restart Windows and check if the issue is resolved.
If turning the Firewall OFF doesn't fix the internet connection issue, then check for other security solutions that could be installed there, 3rd party firewall programs or VPN/ PROXY and uninstall them, if any. Restart Windows and check if the issue is resolved.
If nothing here makes a difference, then it's a task for the Bitdefender Support teams to figure out.

Regards,

Alex

Thanks Alex, It is working now. That goodness because my old laptop stopped working on Friday with the same problem. Both are working as they were last week before the problem. 👍️
