I connect to the internet using a Verizon FIOS router, 802.11g. The brand name is Actiontec MI424-Rev. D. I stream music from my MacBook Pro and/or iPhone and use an Airport Express to connect to my stereo receiver, which is wired to in-wall speakers. The streaming experience is pretty uneven. The Apple Store recommended an Airport Extreme to beef up the network. Note: this is an average Manhattan apartment, not a vast mansion, but there is lots of interference due to a couple dozen other wireless networks in my building. Which is the best way to set up the network for more robust streaming and fewer dropouts?
You basically have the components to configure the routers for a least two network configurations:
Which of these two sound doable for you?
Thanks for that speedy reply! The Airport Extreme can connect to modem by ethernet cable to extend the range of the Airport Express. That's because the Express has the output jack so that I can connect a cable to my receiver so it can then send music to speakers. That is what I would hope to accomplish.
Basically, I would be happy with a single wireless network. I have a wireless HP printer that does fine, and two "smart" TVs that are internet connectible, but I don't care about them so much. I simply want to have one wireless network that is more powerful today than it was yesterday. It should stream, it should send messages to my printer, and allow my Macbook Pro to continue its internet access. Whatever it takes to get there--cables, placement, a wire coat hanger -- I am happy to try.
Ok, then let's start with the following as the basic configuration of your "single" wireless network.
The following are step-by-step instructions on configuring the AirPorts for an extended network:
