Extend wireless network - have FIOS and AP Express
I've found bits and pieces of answers in various posts, but I'm not 100% sure I understand if it will work for me, so I figured I would explain my setup in detail and see what the best options are as far as hookups, equipment, etc.
I have FIOS with the Actiontec router. The Actiontec is in a media closet under a staircase (not ideal for signal strength I know) in the family room on the 1st floor of my house. I only use the Actiontec for DHCP. I have an AirPort Extreme (b/g/n) bridged to the Actiontec that creates my wireless network.
I use Airtunes on the Extreme to stream music (iTunes and other web content like Last.fm) to my home theater, which is also in the media closet. I would like to keep that functionality.
I would like to extend the coverage of my wireless network as the signal isn't so great on the second floor. My preference would be to not run ethernet if I can avoid it, but it is certainly an option. (NOTE: The FIOS line comes into a control panel in a bedroom in the 2nd floor of my house, and there's a phone matrix panel in there as well. Not sure if I could convert some of the phone lines to ethernet and put the router up there, but that is not something I would be proficient at.)
My questions:
Can I use another Express to extend my existing Express? (I don't think so...)
I might be able to get an AirPort Extreme on the cheap - I assume I could put this in the media closet with the Actiontec and use that as my primary wireless and then take my existing Express and put that upstairs and use it to extend the Extreme? But I would lose the ability to stream music with AirTunes, which is a deal breaker. Would I need another Express in the media closet just for AirTunes?
Does the AppleTV provide AirTunes and would that be an option for the streaming music portion?
Any suggestions appreciated!
