I have this problem, just got My laptop with Windows 7 and connected to My house wifi without a problem, but took it to the place where I work and I am not able to connect. I have the password and everything i need but is not even asking for it. Look, i just turn it on, it finds the right connection and when i choose connect it tells me "Windows was unable to connect to this network" when I choose to diagnose the problem it tells me to check the modem and that may be a cable is broken. Another person in the house is using the wifi without problems and myself I was able to connect to wifi through my Iphone here, I even reset the settings to an earlier point and is noot working. Please help!!
