This is usually an issue related the operating system since it also happens with other (wired) adapters. As a workaround I would suggest to roll back to the driver version that worked before or the one provided by the computer manufacturer. As a best practice we recommend the use of WPA2-AES.
I hope this helps.
Unfortunately I have tried rolling back the driver without success. I have completely uninstalled 15.6.1 and reinstalled 15.3.1 (which was working previously without a yellow bang) and I still have the "no internet access" message which is incorrect because I am able to route traffic to the internet. I am still unclear on how to get rid of this false message and yellow exclamation point triangle. I have also switched the AP to WPA2-AES.
Steps taken to recreate this issue:
1. Restore Dell to Factory Image (clean install with ProSet v14)
2. Install Intel ProSet/Wireless 15.6.1 software
3. Yellow bang appears over wired network connection even without wireless connected. Internet works fine.
This is clearly a bug in the 15.6.1 version of ProSet. Once the yellow bang appears, there is no way to get rid of it other than blowing away the OS and starting fresh.
Thank you IanH for the steps to reproduce the issue, it has been reported, we do recommend to install the latest tested drivers from your laptop manufacturer since these would have been tested to work specifically with your exact system set up.
Also to delete the current driver completely see the steps below:
Remove the Intel® PROSet software from Control Panel\ Control Panel home\ programs, ‘uninstall a Program’, check also for any other PROSet software and uninstall it too.
Go to ‘Start’ right-click on ‘Computer’ click on device manager (on the left panel) click on “Network Adapters”\Double-Click the adapter name\Drivers Tab and click on the “Uninstall” button if present.
Remove the Wireless folder found at C:\Users\YOUR_PROFILE_NAME\AppData\Roaming\Intel. (if you do not see the “AppData” folder you need to “unhide “ it, pres ‘alt’ click on ‘tools’ on the top of the screen then ‘folder options’ in folder options click on ‘view’ then select “Show hidden files, folders and drives” then click ‘ok’ )
I have followed all of the above steps, however the yellow exclamation point does not go away and the "no internet access" message persists. Once the version 15.6.1 software has been installed, it permanently displays a false error message in Windows 7. This happens with both the 32 bit and 64 bit versions of the driver.
Additional steps I have taken to unsuccessfully attempt to resolve the issue are to open the network and sharing center, click the icon under View you active networks and then Manage or delete your active networks. I've deleted all the entries and started fresh but still the false error persists.
The error persists with the Wireless adapter completely disabled and no wireless driver or software installed. It seems that installing this software version alters something so deep inside the networking components that the Ethernet adapter is affected as well and displays the false error described above.
Any other suggestions on getting the yellow bang and "no internet access" messages to go away are welcome.
Perhaps resetting the TCP/IP and Winsock may help. Try running the following commands using an elevated command prompt (run as administrator) and restart your system:
Netsh int ip reset
Netsh winsock reset

I am experiencing this same issue on one Lenovo ThinkPad X230 with an Intel Advanced-N 6205 wireless card. I have a whole bunch of these machines with the same Windows 7 Enterprise image, but one machine seems to hate taking the Intel PROSet 15.6.1 package. Just like IanH, after the package goes on, the yellow icon shows up after restarting. The yellow icon shows up even when wireless isn't in use and the computer is connected via Ethernet cable. Uninstalling the 15.6.1 package doesn't fix things. Installing the older version (I have been using the Lenovo provided package 15.03.1000.1637 to start my builds with) afterwards doesn't help either.
I have just tried now to do a totally new installation of Windows on a freshly wiped hard drive. I did not domain join the machine to make sure there is nothing else that could be getting in the way. As soon as I install 15.6.1, the yellow icon appears.
I was just successful in doing a System Restore to before I installed the drivers to get rid of the yellow "No Internet access" icon.
Was an issue with this particular version ever identified? Lenovo is using 15.6.1 as the newest package, but I know there is now a newer version available directly from Intel. Should I skip ahead to that version instead?
I tried 15.8 and had the same issue! Something Intel has introduced in 15.6 and higher is breaking the Windows networking stack upon installation! I am now living in fear that any PCs in my organization get these drivers without my approval as if I don't catch the problem in time to do a System Restore, I have to wipe and re-install the whole PC!
Please look into this issue further!
Some further info about the configuration of the Lenovo ThinkPad X230 that I have this issue on:
- Windows 7 Enterprise x64
- UEFI boot
- Intel vPro enabled on wired and wireless interfaces
- BitLocker disk encryption using TPM (note: I did encounter the problem without BitLocker being used too)
Thanks for not really helping at all.
1) I do not consider the Windows network stack being partially broken to be 'cosmetic'.
2) I already stated that while I had this problem with the Lenovo provided drivers (which I do not believe are customized anyway), I ALSO had the problem using Intel provided drivers both 15.6.1 and 15.8, both on a domain-joined system and on a freshly formatted system.
And I am not even the first person to have had this problem, because the OP had the problem on a Dell Latitude notebook! You haven't helped him and you aren't helping me.
The way I see it, Intel has changed something significant with the driver packages 15.6+, and this is affecting some systems, even if it is only in rare cases. This should be investigated!
I am also seeing this issue on a Dell Latitude with the latest Intel Pro/Wireless drivers. The laptop is running Win7 Pro 64-bit. Windows says there is no Internet access, but the laptop can indeed reach the Internet. Upgrading the drivers (both wired and wireless) to the latest version did not help.
One interesting thing I noticed: When I connected the laptop to our VPN, the exclamation point went away. Not sure what that means, as connecting to the VPN while already on the LAN should not change anything.
