Win 10 WiFi Problem DELL 3521

dell3521 · 13 Mar 2016

Hello, everyone.
I had upgraded my Dell Inspiron 3521 from Win 8.1 to Win 10.
Wifi was working with not problems for a while but now its just stopped and I can't do nothing to fix it.
I run command prompt as admin : reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f
system did not find it.
I did reinstall drivers from dell, also did not help.
I did : "Reset PC". It also did not help.
When I try to connect to my Wifi network it says "No internet. Secured"
It looks like it is connected but no internet access (yellow exclamation mark present).
As I understand I can't revert back to Win 8.1 because upgrade was done more then month ago.
It looks like I am stuck. I am struggling with this issue for two days.
Please, help!

Hi, can any other device successfully use your router?

Have you tried rt clicking the tray icon, Troubleshoot Problems?

Searching the forum (which you're free to do - see the search box above) offers (e.g.)
Solved No Internet Access - How to fix it - Windows 10 Forums
Solved Wi-Fi able to see connections but cant connect. Build 10130 - Windows 10 Forums

You can search for (e.g.
Wifi yellow triangle
Wifi won't connect
etc

Thank you dalchina for your reply.
All other devices can use wifi with no problems.
I tried troubleshooting option, it gave me massage " One or more network protocols are missing on this computer". Attempted to repair with no luck.
Also I have no third party antivirus installed that may cause this kind of problems.

Did this: C:\WINDOWS\system32>netsh int ip reset c:\resetlog.txt
Resetting Global, OK!
Resetting Interface, OK!
Resetting Unicast Address, OK!
Resetting Neighbor, OK!
Resetting Path, OK!
Resetting Route, OK!
Resetting , failed.
Access is denied.

Resetting , OK!
Restarted computer

No wifi.

Also did this: Device Manager>right click> wireless network adapter>uninstalled it.
Network Adapters>"Scan for hardware changes">computer reinstalled the adapter>restarted computer.

Still no wifi.

I was not able to revert back to Win 8.1 but was able to Reset/Reinstall Win 10.

There is list of available wifi networks but on my network says: "No internet Secured"

I think Windows at this moment should say: "Thank you for using free version of Win 10. We hope you enjoy..."

Anything else I can try?
Please, help!

I did this:
1) Go to Network and Sharing Center
2) Change adapter settings
3) Right click on Wi-Fi adapter, select properties
4) Click on configure, then go to advanced tab
5)Property:802.11n Value: 20/40 Auto

WiFi IS BACK

Great! well done... that message "One or more network protocols are missing on this computer" is quite common and useful for finding the many many threads quoting it.
