Hi All I currently have a 3rd generation Time Capsule in my room that I use for my wireless network which works great. However the signal is a little weak down stairs so was looking for ways to improve the signal. I have been offered a 4th generation AirPort Extreme that i was going to install downstairs, I don't want to run a network cable so i was going to set the Time Capsule as create a wireless network / allow my network to be extended and set the AirPort extreme to extend a wireless network. Will this work ok ? will i still get 2 networks 2.4GZ and 5GZ ? Do i need to manually set the channels ?
