Im just put up a new router in my house to split a cablemodem connection and I'm noticing that my web browser is working fine, but I'm having a problem with my instant messangers (Yahoo messanger, MSN messanger, and AIM). I think that all the messages that I send to people are getting out but I'm only recieving about 3 out of every 5, and sometimes fewer than that. Does anyone know which ports I need to open to fix this problem? Thanks for whatever help you can give me
