Mesenger won't let me sign on i tried all the firewall stuff still won't connect what do i do?

1. Check your internet connection


2. Turn off your firewall for diagnostic purpose


3. Check if your internet connection uses proxy (search infor on setting proxy for yahoo messenger elsewhere if needed)


4. Check if your computer connects internet through your organization's network and they block YM.


5. Check connection speed. If it is too low then make it high :D (search some keywords about checking connection speed)


6. YM sometimes has problems in its own network.


7. Bring your computer to other network or another computer to your network :))(joking)
