Windows 7 No internet/network out of nothing!

[Ms. P]

I have a pc and a laptop, both running Windows 7 RC (same version).

Both have the same softwares and updates installed and are (were) running fine.

For 3 weeks I've been running Win 7 on my pc and for a week on my laptop, no problems at all.

But today, I turned on my laptop just to realise that it won't connect to internet/network anymore.

I tried doing all the obvious things... activating and deactivating, uninstalling and installing drivers for ethernet adapter, taking off the battery and taking out of the plug, clearing stuff related to connection on cmd, deactivating ipv6 and so on... nothing works!

Yesterday it was working fine... I didn't install anything, nor updated anything.

I made this new post because I couldn't find anything like this... they're either people who never had connection, or ppl who loose their connection after something happens... which isn't the case here. If I posted sth already posted, I'm sorry.

Thanks in advance.

It seems like you're encountering an unexpected issue with your Windows 7 laptop where it suddenly stopped connecting to the internet or network despite no recent changes in software or updates. Let's troubleshoot this issue step by step. Here are some additional troubleshooting steps you can try to resolve the internet/network connection problem on your Windows 7 laptop: 1. Check Network Cables and Router: - Ensure that the network cables are securely plugged in. - Restart your router or modem to rule out any temporary network issues. 2. Check Network Settings: - Check if the network adapter is enabled. You can do this by going to Control Panel > Network and Sharing Center > Change adapter settings. - Disable and re-enable the network adapter to refresh the connection. 3. Run Network Troubleshooter: - Use the built-in Network Troubleshooter tool in Windows to diagnose and fix common network connection issues. You can find this tool in Control Panel > Troubleshooting > Network and Internet. 4. Check IP Configuration: - Open Command Prompt as an administrator and run the following commands: - ipconfig /release - Releases the current IP address. - ipconfig /renew - Renews the IP address. - ipconfig /flushdns - Flushes the DNS resolver cache. 5. Update Network Drivers: - Ensure that you have the latest network drivers installed for your Ethernet adapter. You can download drivers from the manufacturer's website and install them. 6. Check Firewall and Antivirus: - Temporarily disable any third-party firewall or antivirus software to check if they are causing the connectivity issue. 7. System Restore: - Consider performing a system restore to a point when the internet connection was working fine. This can help in reverting any recent changes that might have caused the issue. 8. Check Windows Update: - Although you mentioned no recent updates, there might have been background updates. Check for any pending Windows updates that might include network-related fixes. If none of these steps resolve the issue, it might be beneficial to seek further assistance or perform advanced diagnostics with the help of a professional technician. Feel free to try these steps and let me know if you need further assistance.
