I want to run a server for myself and my girlfriend. We have computers on the same wireless network, mine's hard wired to the router and her's has a wireless adapter. I run the server and can connect to it but when she tries to connect she gets that "Can't connect, the server is probably down message".

Now, I've read other threads and looked everywhere, I've done everything anyone has suggested and even some things they haven't. Nothing works to allow her to connect. Please, I need some help, I really want to get this working right. Any advice would be great as I'm not particularly knowledgeable about routers and IP's and such.
