Q: Messages not working over wifi

I am currently on an enterprise network, and as of yesterday I cannot send any Messages using iMessage through the wifi network, a Time Capsule set up for my sole purpose.

 

I have full web navigation.

 

I have to connect to my Mobile Hotspot from my iPhone 5 to be able to send messages through iMessage.

 

What can I do??

MacBook Pro, OS X Mountain Lion (10.8.3)

    Hi,

     

    What to you mean by an "enterprise Network " and what does it entail to join this network ?

     

    You mention an Apple Base Station.

    Is this the only router between you and the internet ?

    Is it set to do Port Mapping Protocol ?

    Is it acting as a Wifi point to another network ? (do you get your IP from the base Station or another router on the LAN)

     

    You are saying the iPhone also can't send via this WiFi option ?

    By "enterprise network" I am referring to a protected and firewalled network, not a normal home and small office free access network.

     

    I've tried from my timecapsule, which is connected to this enterprise network and other wifi routers in my building and have not found any router from which I can send messages through iMessage.

     

    We are trying to find out if there is a special port or protocol needed for using iMessage or if only internet and regular HTTP access is required.

     

    I get my IP from the base Station, and it is under another router, from our ISP.

     

    I can use iMessage using my iPhone as a hotspot for my macbook pro.

    HI,

     

    IF the Base Stations gets it's IP from the other router then you are likely to have issues, particularly when you get to Video and Audio Chats.

     

    Apple have this Document  for iMessages and FaceTime regarding ports needed.

    Most devices would have port 80 (web Browsing) and port 443 (Secure web sites and some Mail Servers) open as a matter of course as ports up to 1024 are always open.

     

    Port 5223 is more commonly associated with Jabber servers logins that use SSL.

     

    However this is only half the picture as it is only about the iMessages account in the Messages app.

     

    This Apple Doc deals with the ports used by iChat 2  onwards.
    One port is used by early versions and not by later ones (5060)

    Changes in the Video compression changes the number of ports used in the early version (16384-16403) to a smaller group (16393-16402) which you can see is part of the earlier "group of 20".

     

    Screen Sharing introduced a random port that cannot be listed.

    For this reason UPnP in most routers or Port Mapping Protocol in Apple Base Stations should be used.

     

    Of course the ports need to be open in all devices/routers between you and the internet.

     

    Multiple router set ups

    In most set up there is a device that is issuing IP addresses to all the computers and devices inside the LAN.

    In some cases these maybe other routers or access points.

     

    Apple Base Stations can be routers or Access Points depending how they are set up.

    1) It is bad form to have two devices doing DHCP (Issuing IP Addresses) on a LAN.

    The computers and devices then end up getting an IP from both even though they can display only one.

    iChat and Messages are more sensitive to this than some other apps.

     

    2) Even when one is not doing DHCP (Subsequent devices have Static or Manually set IPs) there can be issues regarding the packets headers and the Addressing of data packets.
