L755-S5275 15.6” Notebook, Windows 7 Operating System
I have had the notebook for only about 6 weeks. Just recently, I noticed messages indicating problems. The Diagnostic Tool included in the computer's software indicates that the Network Test failed. Further checking showed problems with the following Network Adapters:
- Microsoft 6to4 Adapter
- Microsoft ISATAP Adapter #1
- Microsoft ISATAP Adapter #2
- Teredo Tunneling Pseudo-Interface
The indicator showed that these devices could not start. The trouble-shooter said to update the drivers, but this did not work.
Further, under Devices and Printers, the computer shows that it is in need of trouble-shooting, but trouble-shooting and suggestions (updating the driver) did not fix the problem.
While I have not noticed any operational problems with my computer, I am concerned about these problems showing up in several areas. I am also concerned because I have only had the computer for less than 2 months.
Are you still able to connect to your network with this notebook? If so, do you use wireless or a wired connection?
While I realize you're using Windows 7, I did find this article by Microsoft on the issue with Windows Vista machines, and it appears to be a "false positive" so to speak. Again, that article refers to Vista though, so it might mean nothing.
You could try opening Device Manager, right-clicking on the problem adapters, and selecting "Uninstall." Only uninstall one at a time, and reboot after each. If it was my computer though, I'd only do that if I actually noticed a problem with my use of the computer.
