When clicking on the apple botton and about this mac there isn't the option of more info. .. :/

IF i call my ISP can they change it? I have been using them for a while now and it worked before although just recently they have become the ISP for my entire complex so that may =have something to do with this firewall nonsense .. ' i will try changing the listening port and see what happens..
Ihave already deleted the pref.Of LW and that accomplished nothing

Thank you for continuus help I am in much need of it.
