Yellow Exclamation mark over Internet icon

Hi,

Thank you for contacting Microsoft Community. I understand that you are getting a yellow Exclamation mark over Internet icon in the notification area.
I will surely help you to fix this issue.

To understand the issue better, let me know what is the make and model number of the computer?

Try the steps listed here:

Method 1:

I suggest you to run the network troubleshooter and check if it helps.

• Press Start Button and in the Windows Search type
  Troubleshooting.
• Open Troubleshooting and select Network and Internet.
• Run Network Adapter troubleshooter.

Check if it helps to fix the issue.

Method 2:

I see that you have uninstalled and reinstalled latest wireless network drivers. However if you have not tried installing latest Wireless Network driver from the computer manufacturer website, I suggest you to try the same and
check if it helps. Also install all the available Windows Update.

Hope this information helps. Reply to the post with an updated status of the issue so that we can assist you further.
