wont connect on my laptop.? Previously my laptop used to pick up the broadband from downstairs. My landlady changed providers or something and now it wont pick it up. When the wireless button is pressed it says the internet is connected and give the strength of the waves but when i attempt to open the browser it simply comes up with yellow triangle with an exclamation mark in it saying address not found. It always tries to find Yahoo.com. How can i rectify it. I often go to italy and it picks up there no problem.
