I have a Compaq laptop. The wireless on it was working fine until some Windows updates got installed and my wireless stopped functioning.


The wireless router is working fine as I am able to connect to it using my android phone

Device Manager >> Network Devices -- I see my LAN alone listed

I see a device that has an exclamtion mark.

When I do a ipconfig I get something new called

Tunnel adapter teredo Tunneling psuedo interface

Can someone help me out?

Have you tried doing a system restore from before the updates? – David Nov 16 '11 at 17:01
We don't know what your wireless device is either, how about some hints? :) What's 'not working' about it? What have you tried (beyond IPConfig)? – Ƭᴇcʜιᴇ007 Nov 16 '11 at 17:04
Problem descriptions like "not working" are not helpful. Can you get the list of detected wireless networks? Is yours on it? If so, what happens when you double-click on it? You have to give us something to go on. – David Schwartz Nov 16 '11 at 17:46

visit the Compaq/HP site and download the proper driver and re-install. That may address the issue. Using model info, it should be easy to find the needed driver(s)

In the Device manager are there any devices with Exclamation marks.
