I am adding FIOS TV to my existing phone+internet package. I'd like to leave my existing network alone, and simply add the MI424WR as an internal DHCP client. Does anyone know if this will work?
ONT --- Existing Router --- MI424WR +++++ STB
Will I need to open any special ports for the guide information to get through to the MI424WR?
That setup will be fine. Just make sure that you are not assigning any devices IPs in the 192.168.1.100-150 range as that is designated for the STBs in your home. That would result in conflicting IPs, thus no IP-centric services (i.e. guide and VOD) would work.
Alternatively, you can have the existing router piggyback off of the Actiontec router. You can keep the Actiontec at default and set the existing router to a different IP range (perhaps 192.168.0.XXX or 192.168.2.xxx). This way you can totally seperate the two networks- Actiontec for FiOS services, existing router for home data network.
Let me know if you run into any problems with the specific setup.
