    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.

    i created this account primarily to extend a huge thank you to you willsy! i have two laptops and upgraded from win 8.1 to 10 on only one of them so i could see how things went. everything seemed fine at first. when i installed 10 on the second machine that's when everything went haywire. since i lost internet connectivity on both machines i thought it was the cable company. (i have been on this for six nights and a good portion of days too). i replaced the cable company's modem/router with better equipment but no luck. i bypassed the router, but no luck with ethernet either.

    i reverted back to 8.1 on one of my machines and had wifi and woila, i had wifi & ethernet connectivity once again. my victory was short lived though because apparently the trusted security certificates were wiped from my machine. i couldn't even download them from the microsoft site because the site took me to was https and that rejected. in a last weary act of desperation i did a complete reinstall of win 8 wiping out all of my programs & configurations) and upgraded to 8.1 from there i upgraded to 10 again and everything worked--full connectivity.

    i spent the entire night reloading programs and configuring settings getting ready to wipe my second machine when, for no apparent reason, i lost all connectivity again while downloading a program. in a last ditch effort before completely wiping both machines and starting all over with 8.1 as my final destination i read your post and it worked! of all of the hundreds of posts i have read during this last week's journey your is the only one that worked. i wanted you to know that you quite literally saved the day! thank you for taking the time to post your solution.

    Willsy nailed it. This is exactly what happened to me. Once I deselected "BLOCK INTERNET CONNECTION SHARING" in Bit Defender, all the Internets came back. I owe you, Willsy!

    I have been struggling with this for 2 days now. I've been all over the place. Tried different drivers, played with router settings for a few hours, played with any new and possibly related windows 10 settings that I could find, pulled most of my hair out, put holes in walls, wrote my will... until this.

    You sir have solved my problem. Thank you, thank you, thank you!!

    Thank you Willsy.
    Would you believe it, today I enabled Hyper V, on the restart everything seemed fine. Later I tried email and nothing worked, Firefox also failed to connect, checked my hub-fine, PC reported good internet access and no fault found. Spent around 4 hours trying everything I could think of all to no avail, according to the system everything was working but still no internet.
    I borrowed my wife's laptop with the intention of asking here and luckily clicked on this thread.

    Although I had not changed anything on BitDefender I found the same problem and switched off the Block internet connection sharing and internet was back!!

    How or why this happened is beyond me. Anyway thanks a bundle pal

    Just upgraded to Windows 10, no internet connection. Had no problems before on 8.1.

    No network adapters are recognized (Bluetooth, Ethernet, WLAN). Have Atheros Qualcomm AR9485WB.
    Device manager says all is OK, but PC settings say no network adapters detected.
    I tried to uninstall/install multiple versions of drivers but nothing works.

    Any ideas?
    I solved it by going to device manager, locating Atheros Qualcomm wireless the digital signature was the issue clicked on the device and there were 2 certificates one with signature and one without. Selected the Signed certificate and enabled...working great now

    Anyone been able to fix this problem without bit defender?? I'm having this same issue after trying to replace my network PCI card and now I can't see anything old or new card in network connections.... But do see them in device manager. I've uninstalled / reinstalled etc.

    I'm running kaspersky and have tried turning that all the way off with no success.

    Upgrading to Windows 10 from 8.1/Internet issues


    May I ask did you solve your internet problems after you had upgraded to windows 10 and then went straight into your device manager or did you downgrade first and then reinstalled windows 10??

    Omg thanks!!


    I have been having the exact same problem. Have been restoring my system, updating the Realtek driver, called hp support, to no avail. Happened to find this forum and uninstalling Kaspersky actually worked. I'm so happy I want to cry. Thank you sooooo much!!!

    I had the same issue with the network adapters not appearing when I upgraded from 8.1 to 10. The network icon on the task bar showed a red 'X' and the icons in the control panel settings were missing. Device Manager showed that my Realtek card was installed and working properly but I had no internet connection. I tried various solutions on other sites but they didn't Work.

    My issue turned out to be down to Kaspersky Internet Security 2015. Once I uninstalled it the task bar icon changed to the yellow '!' mark and then showed it was connected. The network adapter icon also reappeared in the control panel settings. I then installed Kaspersky again and all is working well.

    Joined this site to say my antivirus program was the culprit as well, blocking my otherwise functional Qualcomm Atheros LAN adaptor, but in my case it was actually Comodo Antivirus. Removing and restarting fixed my problem. Haven't tried reinstalling, as I'm happy to try an alternative free AV.

    Thank you for pointing me in the right direction - I was very close to reverting to Windows 7!
