Alright, I have an idea but I need to know if it will work for sure. I have an Airport extreme running the WLAN in my house. My house is slightly old and is not wired for ethernet. My ISP will only allow my router to be placed at the end of the house opposite my room. NOw, because of wireless N I get a tolerable signal in my room. Now, I have two mac. A White Core 2 24'' imac, and a black macbook. I would like to get a time capsule so I can use both of them with time machine without having to connect/switch my external drive. Wireless backups from the time capsule should work perfect for this, right? The other question I have is that I also have a PC gaming system that I use in my room. It doesn't have a wifi card and I really don't want to bother buying one and setting it up and all that. My question is if I get the time capsule, and keep it in my room, and set it up as a bridge extender for my current airport extreme, will I be able to use it for my backups, and plug in my gaming PC to one of the ethernet ports in order to get internet access? Also, another question. Right now my printer is plugged in to my iMac, and then shared wirelessly. I use my printer for a lot of scanning, so I wanted to know if I use the USB port on the time capsule to share it wirelessly from there, will I still be able to scan?
