Windows 10: Windows 10 reports no network but have internet connection

If I go to the network and sharing center on one of the computers on our home network it reports that it is not connected to a network, but this system can see other computers on the network and access the internet. The other computers cannot see this system, however. This system has an older X38 motherboard with an E8400 processor, but the initial in-place upgrade from Windows 7 had no problems at all. I didn't notice the problem until I realized that about two weeks of backups across the network had failed. I have tried the repair tools in Windows 10 and have uninstalled and reinstalled the network adapter without success. I was hoping that the problem would be fixed by installing the recent big windows update, but windows update reports that it cannot connect even though I have internet access. I have image backups from before the problem occurred, but I am looking for a more simple fix.

Connected to ethernet but Windows not totally convinced

The powerline adapters are fine, they are as they were before the problem occurred. It was just when they dropped out I noticed Windows was suddenly reporting the network state correctly. So when connected to a network but not the internet, it reports
it is connected but not to the internet. When connected and connected to the internet, it reports it isn't connected at all.

 

windows 10 no network connection error but i have internet access

I have internet access, I am using it to write this question in edge however I get a no network access error for windows update and windows store and windows activation, I have tried stopping the service and restarting it ive tried my time settings internet proxy
settings wireless adapter settings, checked my msconfig settings aren't stopping anything, uninstalled all anti virus, opened services and made sure windows update is set to auto tried all the solutions from

here and from youtube to no success I have one more possible solution
this and I will update but so far absolutely nothing has worked, any other ideas?

 

The latest Win 10 update messed up many user's networks.

There are a whole bunch of posts on here with suggested fixes to try.

 

Unfortunately most of the threads deal with the latest update breaking connectivity. In my case the two fully updated machines work fine. It's the one that hasn't updated that is broken and it won't update because windows update thinks it's not connected when it actually is

 

Today I used the media creation tool to update to build 1511. Upon booting up, Edge and Cortana could not connect to the internet, but Chrome and IE could. Network and sharing still said that the computer is not connected to the network. At this point I gave up and I am currently in the process of restoring the final image taken before the initial Windows 10 upgrade??? from Windows 7.

 

Hmm I noticed a WI FI app update last night. Just two minutes my WiFi disconnected. Yet there was nothing wrong with the router. Rebooted and now it's fine.

 

We have five windows systems on the network. Three are on gigabit ethernet including the problem system, the system I'm writing on which is running 1511 and a win7 system. Our Win10 laptop is fine on 1511 and we have a Win7 machine with a wireless ac connection that runs with essentially gigabit speed (no ethernet wiring in that room). Nobody is having problems except the old X38 system. I am restoring Win7 on the X38 with another hard drive. I may try a repair of Win 10 on the X38, which is on an SSD, but then I'll have to reinstall a bunch of software. even if the repair works.

 

I think we're all wasting our time trying to fix this until the underlying problem in the core networking "code" is fixed by Microsoft.

I had my system all good again and the next day everything on the network went invisible again.

 

I agree. The comms between machines is broken.
