Verizon FiOS and setting up Apple network
We just switched from Comcast to Verizon FiOS.
With Comcast we ran a cable modem (no WiFi) into an Airport Extreme base station (latest model with most recent software) which then served as our WiFi point of presence. We ran an extended network to two older Airport Expresses with AirTunes, one hooked to our home-wide stereo system and one hooked to a printer. We did not have the Time Capsule and were not hanging a hard drive off of the Airport Extreme. This configuration worked great - could get on the network everywhere in the house, could stream iTunes (and other applications through Airfoil) to our stereo, and could print to a non-Airprint printer.
Since the change to FiOS, we now have an Actiontec Router WiFi (MI424WR); it is now our WiFi point of presence. I have set up the Airport Extreme in bridge mode, but that doesn't seem to serve any purpose given what I would like to do. In bridge mode, I cannot log onto the Airport Extreme and it cannot connect the old network together. So, I am a long way from being able to stream music to the stereo or print to the printer.
(btw, the Actiontec is not needed for the TV service -- on a different coax line from the main FiOS entry point box. It is exclusively for the Internet presence.)
I have tried to simply set the Airport Extreme up in bridge mode with all the configurations the same as before. Didn't work. I did a hard reset and had to re-setup the machine, passwords, etc. in bridge mode and that doesn't work. I can see the Apple network being broadcast by the Airport Extreme, but it won't let me log onto it. The two Airport Expresses are now completely unavailable -- cannot be seen any longer by the AirPort Utility (says I need the older version in order to configure them).
Ideally, I would like to have the Airport Extreme serve as the main WiFi connection point - with the Actiontec merely passing the Internet access along to it (letting the Airport Extreme handle DHCP). Verizon tech says that cannot be done and that the Actiontec has to do DHCP. I asked about turning off the WiFi from the Actiontec and the Verizon tech said then all devices would have to plug into it directly for Internet access, so I wouldn't want to do that.
Can I set up the Apple network the way I had it before? What else could I do - in terms of network configuration - to be able to stream music to devices like the stereo and send print jobs to the printer?
Or am I simply doing something wrong? (And/or is the Verizon tech wrong?)
