connection to network occasionally

[Kayann]

Hi, please help I am running vista Home basic from Australia and for the past month or so the network will only connect occassionally it used to work every time just fine.

I have opened the port manually by locating the number and going to the exceptions tab in the firewall even though Limewire is supposed to be recognised by the Windows Firewall I sometimes get a turbo connection as soon as I do this but at other times it will not get a connection at all.

I have been trying to connect now since 4pm it is now 7:48 pm and still no connection whats going on, I have uninstalled the Limewire Program and opened and closed the ports manually, I have followed all help advice from the LW webiste and using help, can someone please help thanks.
