[Gnair77]

Hi..

Have come here as a last resort

I have a Sony laptop e series approx 2 years old...
I have been accessing wifi on it for almost the entire time... Was workn on the nternet with my laptop till day before yesterday mornng.....

When i switched it on in the evenng, it suddenly started showing that the internet is connected, but there is no nternet access!!! There was a yellow icon (triangle) at the internet connection icon...!!

I am able to access the same internet with my ipad n iphone, but says 'no internet access' or 'limited access' while trying the same from my laptop...!!

I have spoken to my service provider as well who couldnt help at all....

Please help!!!!!!

Can you connect Sony laptop to another wifi router succesfully?

When connected to (failing) wifi (from command prompt):

ipconfig/all>ip.txt
route print>route.txt

Post ip.txt and route.txt
You may delete both files afterwards
