PC connects to wifi but shows no internet

I have a Windows 11 (24H2 OS Build 26100.7171) gaming PC that can detect and connect to wifi, but shows no internet afterwards. ("No internet, Secured" after connecting to wifi)

The wifi works for other devices like my laptop and using mobile hotspot from my phone gives same result. I tried to connect via an Ethernet cable, but the pc recognises the cable but still cannot connect to the internet.

I have done what most would do in this situation in this age and asked chatGPT to help with diagnosing the problem. But I'm a bit out of patience after following its instruction after 3 hours.

Here are some of the things it told me to try:
ping 1.1.1.1 : works

curl http://1.1.1.1 : some html with 301 Moved Permanently

curl https://1.1.1.1 : error ending in "schannel: server closed abruptly (missing close_notify)", running the command consecutively will give 301 moved permanently and connection left intact

nslookup www.google.com: works

Here is the ChatGPT diagnostics of the things I tried:

    • curl -v https://1.1.1.1:
      • Sometimes succeeds with full 301 redirect from Cloudflare
      • Sometimes fails with TLS abort
    • curl -v https://www.google.com: DNS resolution fails inside curl, but nslookup works
    • No Schannel events logged, so TLS failure isn’t happening at SChannel level
    • Pings occasionally drop one packet, then continue normally

Another thing that might be useful is that when I start my PC (from sleep or boot up), the vibrations are a lot louder than usual (I suspect the PC cooler fan is a bit offset causing this sometimes). When this happens, I will force the PC to shut down and reboot it. This issue started after I woke my PC from sleep, heard loud vibrations and forced it to shut down.

I don't want to include all the things GPT told me to do but I am help to list them out if they are helpful. I am kind of running into a brick wall here and have no idea what to do, so any help on this would be greatly appreciated. Thanks!!

    Thanks for the clarifications.

    I don't see anything suspicious in the screenshot of the network adapters.

    VPNs are notorious for causing this behavior. Try completely uninstalling Proton VPN and see if the behavior stops occurring.

    If the behavior stops occurring after uninstalling the VPN, you can try reinstalling the latest version provided on the official website to see if it doesn't happen again.

    If the problem persists, do not reinstall the VPN immediately; reset the network settings as instructed below.

    1. Press "Windows + I" and select "Network & Internet > Advanced network settings";
    2. Select "Network Reset";
    3. Select "Reset Now", and at the confirmation screen, select "Yes";

    Note: The PC will need to be restarted.

    1. Now open Start and type cmd;
    2. Right-click on "Command Prompt" in the result list and select "Run as administrator";
    3. At the Command Prompt, type the following commands one at a time and press Enter:
    netsh int ip reset
netsh advfirewall reset
netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
    1. Restart your PC and see if the behavior stops occurring.

    Let me know the result.

    Feel free to ask back any questions.

    Hi. I'm David, and I'm happy to help you.

    Since the problem occurs with both Wi-Fi and Ethernet cable, I'm afraid the driver isn't the cause.

    Please clarify the following:

    • Do you have a third-party antivirus installed? If yes, which one?
    • Do you have any VPN software installed? (Even if it's not running at the moment) If yes, which one?

    Also, share a screenshot of the network adapters in Device Manager.

    1. Open "Device Manager" (Windows + X and select Device Manager);
    2. Expand "Network adapters" and take the screenshot.

    Use the shortcut "Windows + Shift + S" to use the screenshot tool.

    I await your reply.
