Just had FIOS installed in my home. Really is awesome. They would not install my Airport Express stating the range is better on their router. Is this true? The range is good, but hate not using my Airport Express that I just resently purchased. Is it difficult to reconnect the Airport Express to the FIOS modem? Any help you can give is appreciated. Thank you!!!
This can get confusing, since we are talking about two different things here.
It is possible to turn off the wireless function on the FIOS router, connect the AirPort Express to the FIOS router using a permanent Ethernet cable connection, and use the Express to provide your wireless network.
That's a lot of work, with no assurance that there would be any improvement if you did this. Unless you are confident in your abilities and adept at troubleshooting, it would probably be best to leave well enough alone and use the FIOS router for your wireless service.
It appears that Allen was suggesting that you use the current FIOS router to provide a wireless signal and the Express (located a few rooms sway) to "extend" the FIOS router signal wirelessly.
That won't work, since the Express is not compatible with the FIOS router for this purpose.
