    Hey all. I rent a house with a few friends, and I have a problem getting the Apple TV working with their router. I had it working fine at my old place, because the Airport Extreme was the only router in the house. Now, I'm using their Linksys router, and I can't get it to work.

    Apple TV will work when:
    It is plugged directly into the Mac Pro via ethernet, but ONLY when Mac is unplugged from the linksys router. I would like the Apple TV to work (possibly with the Airport Extreme?) without having to unplug anything.

    Is it possible to have the Apple TV connected to the iTunes library on my Mac Pro, AND get its youtube/flickr internet connection, without having to unplug my Mac's internet?

    I tried plugging the ethernet from the Linksys directly to the Airport Extreme, but nothing happened. Thanks for any help.

    Hello CJ,

    I had a near identical problem which ultimately turned out to be that I am using a HTTP (web) proxy for my Macs which interfered with iTunes' connection to the AppleTV (well, more correctly: iTunes on the Mac tried to use my proxy to talk to the ATV, and the proxy rightly told it to bugger off).

    If you haven't checked the Apple ATV Discussions forum, I suggest you do so - lots of people are trying lots of things to get their ATVs working...

    If you are using a HTTP proxy, you might like to follow this up...

    That sounds very similar to my problem.

    How do I implement the PAC file solution?

    Looking properly at your diagram, I see that you have a different network configuration than I do: you have your ATV connected to the second network interface on your Mac Pro, right? In which case you have a few other things that could cause the problem you describe.

    (just in case, you can check if your Mac is using a proxy as follows (in 10.5): System Preferences -> Network -> Advanced -> Proxies. You'll need to scroll down the list to be sure. I'm willing to bet it's empty, in which case the proxy is *not* your problem...)

    Check that you can ping the appletv when it's connected at the same time as your Linksys gateway. If you can can't, you possibly have an overlapping network address space allocated to both network interfaces or other such network problem.

    The following should work at all times, from the Mac Pro:
    $ ping appletv.local
    PING AppleTV.local ( 56 data bytes
    64 bytes from icmp_seq=0 ttl=64 time=0.657 ms
    64 bytes from icmp_seq=1 ttl=64 time=0.412 ms

    If the appletv drops out when you connect the Linksys, e.g.

    $ ping appletv.local
    ping: cannot resolve appletv.local: Unknown host
    $ ping appletv.local
    PING appletv.local ( 56 data bytes
    ping: sendto: No route to host
    ping: sendto: Host is down
    ping: sendto: Host is down
    Then examine the network config for the second interface on the Mac, make sure it's using a different network than the Linksys interface (which is probably configured in the Linksys device but the allocated address should be viewable in the Networks System Prefs).

    BTW, have you tried connecting the ATV to the Linksys gateway instead of the second Mac interface? (sidesteps any network route problems as above)

    Good luck,
