OK, bear with me as this may be confusing. In the house I'll be moving into next semester, we have a cable modem w/ a wireless router in one bedroom. I'll more than likely be in a different bedroom. Thats not a problem for either of my Macs, as they both have Airport, but my PC (which will most likely become a PVR) doesn't have a wireless card. So, I was thinking that I would buy an AEx for my bedroom. What I'd like it to do is act as a wireless card for my PC, allowing it to access the internet. At the same time, I'd like to connect it to my stereo and play music to it from my PowerMac. I attached a diagram of what I want to do if it makes it any clearer. Basically, can an AEx do this? Thanks.
