Wireless sharing of internet connection with no wired PC

Hi all...

I'm tring to share the broadband connection between 2 PCs. I would like to move the host pc to another room and connect to the internet wirelessly.

I've set up the infrastructure wireless netork with the host pc connected to the router via ethernet and another computer connected wirelessly. I now want to move the host PC to another room and connect that wirelessly too. Although I can see my network, it wont connect, probablly because it is expecting a wired connection through ethernet. Can this be done? I've read that it can but can't find any advice on how.

Please help me!!

Thanks
