Problem with Windows network.

Hey,

 

So, I came from Amsterdam (4 days), and when I started my computer, I had this yellow "!" on my network icon, telling me that I don't have any internet connection. But guess what, I do have it.

I can open any web page, I can play video games ... everything is working except some windows services (i'm on W10) such as Mail.

 

My GF's PC is connected to the same box, and she doesn't have this problem. I reinstalled my network card (which is integrated to my MB), I changed the ethernet cable, of course I rebooted the box several times, I deleted all the redirection ports and nothing has changed.

 

I didn't update windows since last big W10 patch, honestly I didn't change anything from the moment I left my PC for 4 days, and when I came back.

 

Most weird thing: when I check the network card through the network panel it says:

- IPv4 : no internet

- IPv6: no internet

 

And yet, you can see the card is actually recieving and sending packets. IP config is working, ping function too.

 

Does someone have an idea to solve this ?

Sometimes windows can act like a real bitch if you don't use her daily. This can be a number of things, the main ones are....

  1. IP address was changed by the ISP or windows
  2. Subnet mask was changed by ISP or windows
  3. somehow widows network stack is messed up

I feel it is the last one because you are getting internet services but it is not being registered on the windows network. Try this....

  1. right click the adapter you are using and select disabled then enable it again, then reboot and check to see if the issue is resolved. If it is solved great and go watch your nyan cat or whatever, if not proceed to number 2.
  2. open cmd with administrator rights
  3. type ipconfig /release then ipconfig /flushdns then ipconfig /renew then ipconfig /registerdns <-----is to force windows to register the IP configuration
  4. reboot your system and check to see if the problem is solved

Alternatively/additionally, you can also try this line of code netsh int ip reset c:\resetlog.txt in a administrator level cmd and then reboot. This code resets the whole TPC/IP manually.

If you're getting Internet connection; just with the yellow exclamation mark, just ignore it. It's just failing to read the text file from MS. Detailed info: http://blogs.technet.com/b/networking/archive/2012/12/20/the-network-connection-status-icon.aspx

Do you have any additional network ports (physical or virtual) that are currently being unused but are enabled? Say a VPN port or something of the sort? Things like those could make the icon below show like you're disconnected but your current NIC is connected fine.

 

Also, I echo what Leonard says, specially the CMD lines, those could help reset things on your NIC port.

This is what solved my problem. Mails works again, and the icon disappeared. Thanks a lot mate.

Hey,

 

That's weird. The solution you gave is good, it works ... but when I come from work (PC is out for like 18 hours), I got that yellow ! again ...

 

Does somebody know why ?

Still gets Internet; just yellow exclamation mark? Why not just ignore it?

 

Because it interferes with some softwares such as emails, rivaturner etc ... :/

What servers do those application connect to? Are you able to resolve the address names if it's not an IP address (e.g.: linustechtips.com instead of 104.20.0.11)? Do an nslookup on those address names. May just be a DNS issue if that's the case.

I'm kind noob of regarding this, but I did a nslookup to linustechtips.com, and it seems to work, but when I do it to 104.20.0.11 i got this: non-existent domain.

You don't nslookup an IP, just a domain name. It's name server lookup.

I found the/a solution: I enabled IPv6 on my internet box, and now it works fine.

Do you know why it fixes my problem ?

ISP no longer give out IPv4, just doing IPv6 over IPv4.

 

I'm living the future now. Consumers experience actual IPv4 problems due to exhausted allocation.
