Can you have an Airport Extreme connected to your modem and have an Airport Express setup in another room to extend your network? will you need to have an ethernet cord for the Express if you do this?
You can do that. Configure the extreme to be a network that can be extended. Then configure the express to extend the network (and connect it to the wifi to extend). Real simple! You can also use the ethernet from the express to connect other devices (such as a tv, stereo .. etc).
Do note, however, that placing an extending device too close to the main device can create issues. I've done this and had to elminate the extension due to too strong of a signal from both routers seemed to confuse the connecting device (such as a laptop)
Thank you! But, does the express have to be connected to an Ethernet cable to work? Or is the option for and Ethernet cable only to strengthen the signal if I were to connect it to a tv?
The express does not have to be connected to ethernet to work. The option of the ethernet is used for various different reasons... depending on the topolgy of your network.
Can you do this with an Airport Extreme and an Airport Express?
