Need help with a connection problem

[hyjal]

I can't seem to get bearshare to connect these days.Its constantly showing the red light of not connected.I have changed my settings but to no avail.Bearsgare doesn't even searches,if a search for something it gives "Queued" in the search results pane but the search never starts.I want to know if its a problem with my settings or my Internet connection.Emule and torrents are also not working as they also do not connect.However there is no problem with surfing speed as i can surf through internet without problem.Now i'm bit confused about this problem.Can someone help me out with this problem and how to solve it.

BTW i'm using a broadband LAN connection if it helps to diagnose the problem.
