Windows 7 - Unidentified network, No Internet access

Hello,
I am traveling in South America with my brand new Asus Eee 1005HA-PU17, running Windows 7. I was able to connect to Wifi networks without a problem until 2 days ago, when Windows installed some new updates. Now, when I try to connect to a Wifi network it shows that I am connected, but it also says ¨No Internet access¨ and I can not connect to any sites. I´ve done the troubleshoting over and over with no success. I can see that other people around me are connected to the internet with thier laptops. I don´t know what to do. I´ve attached a screen shot.

Please help,
TJ

Go to the update panel and look at the previously installed updates, get a shot of what you installed so we can see what you did.

Well it says you are connected just not to the internet ?

Try restarting the router.

Zen00,
I was not able to find the information for the update that Windows installed automaticly, probably because I restored the system to a point prior to the installation. Should I look somewhere else?

aem,
This is not a router in my home. I have had this problem on every network that I have tried to connect to since my computer restarted to install updates. I have tried to get online in about 3 or 4 different locations so far. I´m travelling for the next year, so I´m connecting to Wifi whenever I get the chance.

OK,
I found some information on the update and have attached some screen shots. The update in question occured on Jan. 16th.

Please try disabling the windows firewall

What is your Wifi Adapter make and model ?

If you know the manufacturer, just download the latest drivers for the adapter !!!

You can try downloading the latest WIFI drivers for your hardware.

Isnt there a setting for each one that allows access to the Internet? I am sure there is because I had the same problem with my new router/laptop after an update. It also said no internet access. I looked through all the network stuff and found a tickbox somewhere. Cant look it up at present as I am at work with no access to my Windows 7 laptop

Nothing to worry about it.

* If, you have any wired connection, connect your Laptop and try updating the WIFI divers

* Try to find out the adapter brand name and model from LAN properties !!!
