Problem connecting on LaptopFollow

I seem to be having some trouble connecting on my laptop when using my wireless internet connection. I tested my connection going directly wired to my LAN and it worked fine. It's only when I am on the wireless connection that I have problems. I keep getting an error when connecting to server, or it will tell me that service connected but it will never load. I am wondering if anyone has any suggestions on anything I can try to run the game while on my wireless connection. Thanks for any suggestions.
