Laptop is saying I'm not connected to the internet, but I am?

[Sonical]

I'm currently connected to my internet using wireless and It says on the connections list that I'm actually connected to my internet but at the top it says ''Not Connected. Connections are available.''
It works fine on the internet and skype ect, But when I try to go on games and use Steam it says that I need an internet connection. Also the little sign at the bottom for the internet list is like a screen with a ethernet cable at the left side of it, I'm not sure what that means.
Can anybody help with this please?!

Try Wired connection and see if you are connected...
if you are then in that case you will have to reset the wireless settings...

why not switch off your wifi and your computer for about 30 sec. disconnect the wifi cable to the socket too and then reconnect them again.

try to unplug the wifi cable for more than 10 seconds, turn off your comp and turn it on again, it always works with me
