Skype does not connect via my home WiFi any more [ Edited ]

[skpesn]

I have Skype on A Mac.  Connected to the internet through my home cable  wireless router. Until last week Skype worked fine.  Now it tells me I am offline.  When I try to go online I get a message about 'your current wi-fi network does not support Skype.  Tip. Skype does not work with private or closed networks."  If I disable the wi-fi network, then I am off-line.

Are you on the latest Skype 5.5 for Mac from www.skype.com/go/download ?

If you are you might want to try disabling "Skype WiFi" via Skype's preferences.

I am having the same difficulty with skype. I have seen suggestions of going to 'tools' or 'preferences' to logout of wifi....or something. I cannot find 'tools'! I cannot find 'preferences'! My only phone is skype, and it hasn't worked in over a day. I am at my wits end! Can you help me?
