So I'm a little confuzzled here, hopefully somebody can help me out. I have a router in the basement that all of my devices (MacBook, iMac, etc.) connect to. I have a Time Capsule (2nd generation) in my room (two stories above) that I use to backup my data. I decided to bring my (old) PC to my room and unfortunately it doesn't have a wifi card (Dell Dimension 4700 from 2005 running Windows XP). Question: I've tried connecting my Time Capsule (wirelessly connected to my router) to the Dell via ethernet but internet still doesn't seem to be working on my Dell. I know the Time Capsule can be used as a wifi extender but if I have a wired connection to my Dell, shouldn't this work? If not, should/would I need to enable the wifi extension feature on my Time Capsule (not sure on how to do that)?
