Not connecting to local wi-fi network

Good morning, I connect at home wirelessly with no issues using W7 Ultimate on my Fujitsu laptop. I don't really understand all the different types of network but currently I share with no one, and under the network settings it states 'Home Network' and then 'Ready to Create.'

I was away for work recently at another site and they have an open wi-fi for visitors to use on non-work laptops, so it's passworded but other than that, it's totally unrestricted.

When I tried to connect it found the wi-fi network with full strength but would not identify and connect - the password was okay as I when I tried an incorrect one, it stated just that.

Do I need to do something different with regards to grouping/network etc or could the fault have possibly been with them?

Thanks - Blue

Note: it used to work on XP Pro!

Have you made sure the security type (ie WPA) and encryption of the wifi matches your windows 7?

Click on the wifi icon in tray, right click on the wifi name that you are connecting, choose Properties and in Security tab, check what settings are been set.

Don't forget to come back and let us know. :)
