Diabling IPv6 worked for me. Thanks for the article, this was incredibly frustrating!
If it’s not there, move to the next method because this isn’t applicable on your system, probably because you are on a home version.
In: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowssafercodeidentifiersPaths. I have only got codeidentifiers. There is no Paths for me? But in codeidentifiers. I have got a REG_SZ that is named (Default) and REG_DWORD that’s named authenticcodeenabled. Is this what I delete?
My problem was that my network did not have any new ip adresses. I checked it using ipconfig in the cmd tool and got an 169 address. I went into the admin section of the router and increased the dhcp-scope. Now it’s working.
Actually this is the exact solution.
Disable IPV6-
(disable while trying internet from the WiFi connection having this problem> for me the problem persisted only to some specific WiFi SSID not all).
then restart.
Took me around two months to fix, as I could browse from all SSID except the Office SSID.
Man I’ve exhausted every single one of these and some I’ve seen in the comments 
Nothing’s working
You can also try a system restore to the point when the system was working fine.
see heading titled “Restoring the System using System Restore Point”
Unfortunately, no dice. I’m going to try uninstalling my anti virus software.
Will wait to hear the results.
I uninistalled my avg antivirus and it all worked fine , give it a try , uninistall you protection and it would work
I tried all above with my antivirus on and all failed , uninistall protection first and then in it presised do all these steps , very good spet by step
Excellent, I just disabled IPv6 in Ethernet connection settings then disabled and re-enabled the ethernet adapter and it works now!
Thank you for sharing your solution!
Method 2 fixed my issue after no disk to boot error… Thanks
What is the make and model of your system?
This is the first thing I tried after reading many (difficult) solutions and IT WORKED!
Thanks a lot. To add a little more info: I did an W7 upgrade to W10 on an Intel NUC.
I tried them all. None worked for me but disabling the proxy in my “network proxy settings”. New way to fix it.
See if you can disable IPv6 from your router.
I’ll be online wirelessly and suddenly lose connection. I get the protocols missing error when I troubleshoot. If I disconnect and reconnect everything starts working again. Problem is, I’m constantly getting disconnected. Some of the suggestions here work, but again it is just temporary and frankly it is easier to just disconnect and reconnect to the network, but why does this keep happening?
Tried updating both. No new versions available .
Thanks, I will try that but everything worked perfectly until yesterday.
Unfortunately, that doesn’t fix it.
