My laptop, a Dell M1330 running Vista 64 bit, would not boot for some reason. Now it boots up. I have a wireless network in the house. Another laptop and a palm top connect to the internet just fine while the one that I had a problem with does not. I have tried 3 different web browsers. I'm told I'm connected with limited availability and 4 of 5 bars are lit. Running the troubleshooter I am told to plug in my connection. There is nothing to plug in t5haqt I know of. Ideas?
