I have a Gateway NV73A03u laptop with
4GB memory
running Windows 7 Home Premium 64 bit
AMD athlon II p 320 dual core
 
The problem is when I do updates I lose internet connection, either with Internet explorer 8 or Firefox. The wireless is connected and i get the same thing when i connect a network cable.

If i do a restore back to the point before I do updates the internet works fine, after updates no internet. I have tried everything that i can think of to get it back.

Does any one have any ideas ?

I tried to disable IPV6 but it still pulls a ipv6 address

You cannot update your computer in safe mode with networking because certain services are not running.

Its seems like when you are install the updates you are installing network drivers update.

Go to control panel- windows updates-change settings-select check for updates but let me choose to download and install.....

After you do that updates will not be installed automatically and you will get an option to choose which update you want to install.

Install 2 update at a time and find out which update is creating this problem.

I think its the network driver update thats causing it but still check it.

I have to agree with ded9.  When you run the updates, do not run updates for the NIC or Wireless Cards.  To get rid of IPv6 tunnels go here: http://support.microsoft.com/kb/929852.

Sounds like you might have two network adapters in the device manager after performing the updates because of which you cannot go online. Check device manger-network connection when you are not able to go online.

There is a known issue with  network cards and windows 7.
