Windows 10: Just upgraded to Windows 10, no internet connection

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?

Problem with internet connection

I have just upgrade to Window 10. Then I try to access the internet. The internet connection has no problem, I can access it using Internet Explorer. But my Google Chrome and other software cannot connect to the internet. Is it a problem lead by the upgrading
of Windows 10?

 

Wi-Fi is on // No connection (after Windows Update)

On Oct 13 windows updated.

The update must've invited malware into my computer. I tried to run my antivirus after the update but it said there's no connection. Google chrome lost connection as well and then I got a pop-up saying that Windows Defender found and blocked a "Severe Trojan
threat". So I deleted it and I still don't have connection... (weirdly) the only thing that works is the Explorer app. I have internet; the Wi-Fi works just fine but, everything else doesn't connect. It's something internal that must be causing
the problem and it all started after the update.

P.S.

It also changed my network from private to public so I had to fix that.

And YES, I did allow these programs through the Firewall so that's not the problem.

 

Same issue here .... device drivers are installed but both wifi (Intel Centring N 6235) and Realtek PciE card are showing disabled.
No VPN software installed as I uninstalled them ... tried to do a reset but that fails to complete and unable to downgrade to windows 7 as the system was functional for a full 2 days before this happend. Any pointers?

 

It seems I solved it. I a reset (not to factory to settings) while keeping my files but it erased all my apps including Cisco VPN and others such as google drive, all ASUS original pre-installed wares etc.... In doing the reset, it re-installed 10 automatically and then the internet seems to work fine so far. Which is a relief because it did not work at all before. The only annoyance is I have to reinstall even WORD, EXCEL, ACROBAT etc... which is a bit surprising. But anyway 10hrs of work seems to have salvaged my device. Another 10 to get my IT department to re-install the softwares that were deleted including CISCO VPN....

 

Glad to hear you got it working ... I tried a reset but it seems to fail ... maybe I'll try it through safe mode and see if there is any joy.

 

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.

 

I'm having the same issue, Dell XPS 502x Upgraded from 8.1 to 10. No network adapters at all. In the Device manager there are warning triangles on network adapters (intel centrino wireless-n 1000) But not sure what drivers to download. I'm assuming the ones for win 8.1 are no good.

My other laptop updated no 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.

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)

Attachment 28043

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 have had the same problem and I am using bitdefender (I spent all weekend trying to resolve this issue(day and night) after three goes at installing win 10 I am now back on win 7 i do not have the time at the moment to try again. I will try at a later date.

tried internal Realteck pci family lan 10/1000 (gigabyte F2A68HM-HD2 motherboard).
and a wireless tp-link adapter (informed by manufacturer that drivers comming soon).

 

Same problem for me...do not have bit defender or VPN. All drivers are up to date. Have a dellXPS 8700. Have backed out to win 7 and have no problems. Microsoft had me download a program called media creator that they said would fix the problem...it didn't.

 

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. *sarc

 

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

 

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.

 

Thank's Willsy, great fix, worked for me.
