I currently use a time capsule for wifi at home. It's located in my basement. The problem is the signal strength on the second floor isn't the greatest. I was wondering if I could extend the network by running a cable from the time capsule to the second floor and plug it into an airport express. Is this setup reffered to as a "bridge"? If I do this, will I have just one wireless network (which is preffered), or will there actually be two networks and the devices connect to whatever network has the better signal? I'm sure this is a pretty common setup. Can anyone provide any insight on this. I.E. pros and cons, setting it up, ect. Appreciate any replies.
