Just upgraded to Windows 10, no internet connection

HardyRexion said:

Strangely I fixed mine by going to device manager, deleting the problem adapters the rescanning for new hardware. Both the wifi and ethernet adapters were found and working.

I also did that but it did not fix the problem...

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.



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.

Willy this post solved my problem, thank you so much. I took it a step further in Bit Defender.

First for those that don't know how to find the firewall setting inside bit defender
its under Protection > Firewall (wrench icon) > Willy's fix is under the settings tab.
I went to the Adapters Tab and for my Local Area Connection it was set to Home/Work - I switched it to Trusted.
Seems Windows 10 has a different classification now for the adapters.
Not that internet connection sharing needs to be on either, but setting the Local Area Connection to trusted i was able to leave the internet connection sharing on and it works.

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.

I have had the same issue with bitdefender.I rest the firewall setting and all seamed ok for about an hour then internet dropped again unistalled bitdefender and now its working fine again.is your connection still intact?.
I shall investigate the bitdefender forum to see if they have any answers but i won`t hold my breath with that site.
back soon Topper.

Yes, still intact. Looking good so far.

OK good. I have just been on the BD forum and reinstalled it again using this download link What To Expect From Bitdefender 2015 After Upgrading To Windows 10 - Bitdefender Forum recomended by BD and have set internet sharing to enable. I will test it again and see how it goes.
An interesting note: the set up using this link was slightly different than the automatic upgrade when installing Win 10.

Will report back after a few hours if O/K or not.
Topper.

Thanks HardyRexion

Deleting the "working" ethernet controller in device manager and then scanning for hardware changes worked for me also.

Yep after five Hours this seems to have cured the problem.Why the bitdefender automatic software upgrade did not function properly i don`t know, still fingers crossed.
