Itunes Sharing not working over wireless

[jumpin68ny]

I have three PC's both running the latest version of ITunes.

Desktop 1 is running Windows XP and connects directly into the Action Tec Router via a wired connection.

Laptop 1 is running Windows 7 and connects to the Action Tec router via a wireless connection.

Laptop 2 is running Windows Vista and connects to the Action Tec router via a wireless connection.

All PC's can connect on the Internet.  The wireless connection uses WPA/PSK.  Any firewalls are disabled.

Desktop 1 can see the Library of both Laptop 1 and Laptop 2.  From Desktop 1, When I click the library of laptop 1 Itunes says "laptop1 library is not responding".

Laptop 1 and Laptop 2 do not see the library of either Desktop 1 or the other Laptop.

If I move Laptop 1 from a wireless connection to a wired connection, the sharing works fine.

Anyone know why the wireless is causing Itunes sharing to not work?

Thanks, Jim

#1 When you have the laptops connected by wireless, with all of the computers go to http://whatismyip.com/

#2 All of the computers should be coming from the same Public IP (what ever the IP Address at that site is ).

#3 If not, the laptops connected to the wrong wireless network. We can deal fix this, as need be - if that is the case.

#4 If all them are coming from the same public IP, check if all of the computers have the same Default Gateway OR not.

#5 If not, please post. We will figure out, what is going on..

For Windows XP checking the default gateway.

a) Go to Start -> Run.

b) Type in cmd and press enter.

c) In the new window, called the command prompt, type in ipconfig /all and press enter.

For Windows Vista (and maybe Windows 7) see http://www.ncsu.edu/resnet/windows/ipconfig/vista.php

All devices are on the same subnet and all connect to the same public IP.

All devices have the same default gateway, whether its the windows xp, 7 or vista machine.  My VZ has been reconfigured to use WPA2-PSK with a unique name.

Ok.

#1 In the router go to Advanced -> IP Address Distribution.

#2 What is the DHCP Range?

#3 In the router go to Wireless Setup. Then in there, I believe Advanced Wireless Setup.

#4 Is there anything about AP Isolation?

#5 As need be..

a) In Wireles Setup -> Advance Wireles Setup, take a screen shot of what you see(

b) See as need be http://take-a-screenshot.org

c) Re-edit the screen so that you do not show the SSID, MAC Address(es), and the WPA key.

d) Post the image, for example using http://tinypic.com/

[jumpin68ny]

2 What is the DHCP Range?  192.168.1.2-254

Not sure what you want from the other items, wireless is set up except I'm using WPA2/PSK and not WEP.

Dont see anything about MAC address on the screen you mentioned.

Using the Attachments entry at the bottom of the reply is far easier than messing around with a third party picture store.

Today I took my desktop and laptop and connected them to a linksys router and the sharing worked.  When I moved the connections back to the actiontec router the itunes sharing stopped working.  If I move the laptop to a wired connection into the actiontec sharing works fine.  There is something about the Actiontec wireless preventing the itunes sharing.  The actiontec router is using WPA2-PSK.  No other configuration changes.

Anyone have any input or thought?

Thanks

While I do not know what the model of that Linksys is, I have an idea for testing reasons.

#1 In the Linksys go to Wireless -> Advanced Wireless Settings.

#2 Enable AP Isolation, and press Save changes.

#3 Please confirm or deny that iTunes does not work with AP Isolation turned on.

^^

The linksys is an old wrt54g and when I enable AP isolation Itunes shares does indeed work.

So this morning I was playing the Windows 7 laptop and decided to delete my windows wireless profile on the laptop called home and my existing home SSID on the Verizon router.  I created a new SSID called boo with no security.  I connected to that SSID and Itunes sharing worked between the desktop and laptop.  I then added WPA2/PSK to the boo SSID and sharing still worked.  Finally I went back to my original SSID called home and WPA2/PSK, recreated the home profile and Itunes sharing worked again.

I then went to the Windows Vista Laptop and without making any changes to it, Itunes sharing worked.

So in the end it seems deleting the current SSID configuration and rebuilding it on the verizon router cured the problem (for now).

i have this same problem with actiontec, but not with sharing - with airplay not working.

Just like you, if i hardwire to the actiontec, i can airplay and the icon shows.  When i use wireless, it does not show the icon and it does not work.

I tried your SSID trick, but not modifying the WPA2 key.  I stil use WEP, currently.  Any idea what is differences there are between wired and wireless from the same actiontec router?

[primarykey]

I have the exact same problem, but not with iTunes but media center sharing DLNA / microsoft. I'm trying to access and play my library from wired computer on a PS3 (wireless) ... the PS3 (wireless) can see my laptops (wireless) but not my wired desktop computer. When I move a laptop from wireless to wired, the PS3 can no longer find that laptop either.

I have done some packet sniffing on both wired and wireless computers when PS3 is searching, and found that the wired connections are not seeing the broadcast packets from the wireless segment. The wireless computers see (and respond to) these broadcast SSDP packets.

1. this is with the Actiontec router MI424WR rev I that Verizon sends everybody...

2. all firewalls are off (triple-checked) take my word for it

3. wireless security is WPA2

4. all computers are on the same subnet and have the proper netmask, etc... I can ping from any box to any other regardless of physical connection - the issue seems to be these broadcast packets.

5. I have contacted Actiontec and they said they don't know what is wrong but that is not excpected behavior - they suggest I open a ticket with Verizon engineers so they can investigate...

How do I open a ticket with Verizon engineering? I'm loathe to dial into the normal tech support with this problem as they likely won't know what I'm talking about. Will suggest I reboot everything (again..) ... you know?

Anyway.. any ideas ?

It is the actiontec router.

I did get it to work reliably ONE way, which WILL NOT suffice long term but here is what works:

My Network->Network Connections

From there, the first one on my list is Network (Home/Office), with sub networks showing for Ethernet (the hardwire switch) Wireless, and Coax.  At the parent level of Network (Home/Office), if I modify the settings and change the property 'Network' to 'Broadband', the iTunes airplay instantly shows up in my wireless connected macbook.  I can then airplay to my wired AVR...

SIDE EFFECT: I get no WAN connection within this network any longer.  So, it CAN work, but something to do with the various Network settings doesn't let it work while connecting to internet...

Id like to resolve this since if I get an AppleTV, I will have the same issue since its going to be hardwired...

SIDENOTE: When I hardwire my laptop I can airplay to the airplay device on the same hardware switch in the actiontec...

[swizzchard]

OK I have this working reliably, now.  AND with still being able to hit outside my LAN 🙂

If you go to Advanced (Accept the warning) and go to the IGMP Proxy menu and disable IGMP Proxy.

This magically makes it work!  I still haven't read up on what the IGMP setting does, but it is a proxy, which obviously interfereres in this  case with AIRPLAY udp messages being broadcast and received.  Hopefully it doesn't adversely affect other devices on my network, but I can cross that bridge then.

[primarykey]

Thank you Swizzchard!

I've been looking everywhere for the setting that's blocking the multicast packets... I did a little reading on the IGMP proxy, and it's clear as mud... as are all of the settings in the MI424WR below ENABLE/DISABLE lol... there's enough settings on IGMP proxy in there to impress a cisco engineer... useless for me, tho.

thanks again!

[Kirkus1]

Swizzchard above nailed it.  The IGMP Proxy set to disabled solves this problem.

[Simon601]

Man, I've been trying to figure this out for days.  Finally stumbled on this message chain.  It works.  Thanks.

[patp1946]

great solution.  Worked for me. Disabling the IGMP Proxy was the fix.  Kudos to swisschard. This fixed both my Iphone synch issue and my Apple TV homesharing problem.

[Abkacb]

THANK YOU.  I have been working on this issue for days.  Reset router, reconfigured my entire network, rebuilt my PC and wiped my iPhones and iPad and nothing until I stumbled on to this.  I practically cried when this change Worked.

[aforty]

Thanks for the tip! For me it only go me half-way there, I then had to then manually allow IGMP on all my devices. Kind of annoying extra step, would love to know if there's a way to automatically enable IGMP for all devices. For the record I have the MI424WR gen/rev 2.

After disabling IGMP Proxy I was finally able to see my AirPlay device but it would just not play anything when I connected.

In Advanced Settings/IGMP Proxy/Host Multicast Filtering, I had to click the action link on for all my IP addresses and manually enable IGMP. Once I did this everything worked perfectly.

Thanks swizzchard, this had been plauging me for days!

[gene93]

Perfect! After rebooting the reouter everything works.
