Hey guys! So I think I know the answer but I wanted to say it aloud and see if I am missing anything. Right now I have an older, single-band time capsule that works fine, and 2 older airport express units that I use for a printer and a radio. We're moving soon (first house!?!?!), and I need to have 2 separate networks. Rather than buying a new TC and new airports, can I add an AirPort Extreme and just run the TC and the older airports in the chain? Are there downsides because of how old they are? Would it be worth it to just upgrade the whole lot? FWIW, we have newer iPhones, but the computers we have are older: late 2008 MacBook and I think an early 2009 iMac. Is this a stupid question?
