You said you made the test. Was it this port test?

If that's the test that didn't work, something is blocking LW's default port. Do you see the firewall icon (brick wall in front of the blue earth)?

Have you been through this sticky?
Connection problems? Check here first!
Since emule doesn't work either, I'd be suspicious of your ISP. Do you know anyone who has the same ISP & uses p2p successfully? It would help to know the brand & model numbers of both your modem and router.

Have you tried changing to a higher port? There are instructions & info here
