    SOLVED!: My Third-Party Bit Defender Firewall Was the Culprit!!

    I hope this advice helps someone, I spent days scouring threads trying to find an answer for why my Windows 10 wireless worked flawlessly for a full 48 hours after I upgraded and then just stopped! Here's what happened to me and how I fixed it.

    OS:
    Windows 10 Pro 64Bit

    WIFI NETWORK ADAPTERS USED:
    Qualcomm Atheros AR5BWB222 Wireless Network Adapter (Built into Motherboard)
    Netgear WNDA3100v2 N600 Wireless Network Adapter (USB Wifi Dongle)

    SYMPTOMS:
    * Qualcomm Wifi worked flawlessly for almost 48 hours after upgrading from Win7 to Win10. No hitches.
    * On 3rd day, booted system and everything seemed normal, Wifi connected, no yellow exclamation mark. Internet detected and flowing normally according to the Qualcomm Wireless adapter... BUT!
    * All internet reliant apps not working e.g Steam, Team Viewer, Spotify, Dropbox, AV updates.
    * Go to any browser; Windows Edge, Chrome or Firefox, cannot browse to any website.
    * Checked 'Device Manager' All adapters functioning without issue. Un-installed & Re-installed all just in case.
    * Installed Netgear USB Wifi adapter to test, same symptoms (And Netgear state it's Windows 10 compatible)
    * Tried installing a Legacy Wifi adapter - still no luck.
    * Had 'Tunngle VPN' installed, other threads advised to remove any VPN's and re-install. I did this but no change.

    MY SOLUTION:
    Just as I was signing up to this website to get some answers I thought back to what I had last installed on my PC. I had updated my Bit Defender Internet Security 2015 software just before my previous shutdown. I though maybe its firewall is up to something weird... Sure enough I turn it off and BOOM! Internet!

    * The culprit stopping my internet but causing all adapters to think I was still connected was an annoying wee setting under the advanced settings of my Bit Defender Firewall called 'Block Internet Connection Sharing', I switched this setting off and all is peaceful in the world again. (See attached screenshot - top setting)

    It maybe worth checking your firewall even if it isn't Bit Defender for a similar setting. I hope this information saves someone much frustration and wasted time.

    You don't need to uninstall bitdefender. I'm using bitdefender internet security 2015.
    Goto Bitdefender Firewall:
    -. Disable Block Internet connection sharing
    so far, my internet is still working.. finger crossed
    Thank you so much "newme" I have Bitdefender also. I went to the firewall, unchecked and it worked great so far, but I wonder what will happen when I restart. I spent hours on the phone with my internet provider. But it's OK at least I have access now. Thanks again.
    It is the next day (8-4-15) and I have been on and off the internet 8 or 10 times and everything is working great. If you are having problems check your security program settings it may work for more than Bitdefender.

    I had the same problem too after upgrading to Windows 10, I have tried everything I found on the internet but it did not work.

    Maybe Internet access is blocked by firewall. Check your firewall setting, if you have firewall from the third party, just turn it off.

    I just solved the problem simply by turning off the firewall from the third party application (I am using bitdefender as third party antivirus). now I only use Windows firewall and there is no limited access anymore

    so many thanks


    Thank you so very much for posting this. I was pounding my head against the desk all day trying to figure out what was going on. I was very afraid I was looking at having to reinstall win8.1. You are a sanity saver!!

    THANK YOU

    I spent the last six hours trying to fix the wifi problem (and internally crying in the process). I even contacted my internet provider and even had a technician come to my house only for me to realize that it might be a driver error (since the wi-fi was working normally in both a windows 7 laptop and my phone). Then I used the other laptop to check for a solution and found yours.

    Effectively, Bitdefender was being an annoying b*tch (sorry for the language, but I'm still pissed at the fact that I have wasted several hours of my life that I could have used to do useful stuff, like schoolwork).

    Again, I can't thank you enough for sharing your solution.

    I just started having this problem today on my Surface Pro 3 that I just upgraded to Windows 10. I too found that turning off the "Block Internet Connection Sharing" option on the Bitdefender Firewall. But, I searched Bitdefender Support Center and found this solution which worked for me and I was able to keep the "Block Internet Connection Sharing" switch on:

    What to do if I lose the internet connection after upgrading to Windows 10?

    If you are having issues with the internet connection after you upgraded your OS to Windows 10, please set the Bitdefender Firewall correctly, by following these steps:

    1. Open the Bitdefender program
    2. Click on the Protection module and then click on the Firewall feature
    3. Make sure the Firewall is turned ON and then go to the Adapters tab and perform the following changes:

    • at "Network Type" select "Home/Office"
    • at "Stealth Mode" select "Off"
    • at "Generic" select "On"

    Now close the Bitdefender window and restart your system.




    Hope this helps!

This also happened to me while using windows 8.1 but I got it fixed everytime with a simple "netsh" command. Now things aren't this simple, i tried multiple fixes and none of them worked. I tried to update the driver from the device manager but i can't find the microsoft and the producer driver, instead i find some outdated drives from like 2013.

    Thank you for the time you put into reading my post.


    I hope this could help the problem with internet connection

    Go to SETTINGS then open NETWORK & INTERNET. under wifi section scroll down to related settings and open CHANGE ADAPTER OPTIONS. then right click "Wi-Fi" and click diagnose. It will detect the problem and resolve it.

    Finally got it working

    I have had the problem for over a month now since converting to W10. I have been trying to figure out why it took so long to find networks and then connect to my own ... sometimes up to 5 minutes.

    Now solved - fixed it instantly without uninstalling, reverting to previous W7/8. But it may be my particular instance.

    I have ralink RT3290 as WiFi Adapter.

    1. In Control Panel | Network Configurations right click the Adapter and select Properties
    2. In Properties Click Configure button on Networking Tab screen
    3. Under the Advanced Tab select Roaming Sensitivity (mine was set to medium) and change to 1.Advanced
    4. Select OK


    All networks immediately appeared and connected to my home network.
