Internet connection dies - Restart Needed

2008-11-01, 18:47 PM


I just installed SP1 for Vista, and SP1 + Vista fix for Visual Studio + SP2 for SQL Server 2005. After the update I noticed that the 6To4 Adapter had the yellow exclamation mark (!). So I deleted in the hope that Device Manager finds it again and I can reinstall, but now it is not being found. Afterwards I started getting Internet disconnections.


After some time online, and without any exact timing, totally random, the connection kind of dies. Only network traffic travelling on HTTP seems to die. I remain connected on IRC, MSN, Skype and ICQ. Browser action just dies. I tried different browsers, Firefox, Chrome, IE to no avail. I could not start any connection.


It seems the DNS is lost. However other computers connected to the same router and with the same wifi router remain connected so its definately something which regards the Lenovo laptop.


Also this is the result of running "route print" now that the connection is dead (As I wrote this post the connection died. Had to restart and just submitted it after restart)


 C:\Users\mr matthew pulis>route print

Persistent Routes:


As you can see the Persistant Routes is empty which is quite strange.


I tried to update to the latest Intel 945ABG Wifi drivers - have the Dated : 28/8/8 to no avail.


My System is:

Lenovo 3000 N200

2GB Ram

T5450 CPU

Vista Home Premium SP1



Please note that I have updated ALL Windows + Lenovo software - there is nothing pending. All updates were finished succesfully.


Any help is extremely appreciated  because this problem is driving me terribly crazy!

Please read 'resolution' on: http://support.microsoft.com/kb/932520/en-us

This looks like a problem with Vista.

Try older driver version (or rollback driver) if there is any.

Check if you have any windows updates again.

Hi, I had the same problem, after try many posible solutions (without success)


I found that the tool "Access Connections" had an Option: To permit wireless LAN radio off ....


Unchecked the mark and that´s it. These was the problem.

Your solution sounding so wonderfully simple, but didn't help on my X301. Still looking for the answer...
