Messages video chat stops after 30 sec

Recently, I've found that after starting a Messages video chat, there is a significant chance that after about 30 sec the chat will drop unexpectedly. Messages reports no data has been received for the last 10 sec and offers to send a report to Apple. Sometimes my Airport Extreme appears to reboot kicking me off the internet, but other times it keeps going allowing me to reinitiate the video chat and continue for as long as we want to talk. The console shows no errors between the time the chat was established to the time the link is dropped. I do see errors after the event, but I'm not sure if they are related to the cause of the problem or just downstream errors. The problem started a few weeks ago around the time I replaced my old Airport Extreme with a new unit, but that may just be coincidence. Does the Airport Extreme generate a log that I can view?

It looks like the AirPort base station is in connection-sharing mode, and is connected to a broadband device that is also in that mode. One or the other should be switched to bridge mode. If you choose to reconfigure the base station, set the Router Mode to Off in the Network tab of AirPort Utility. Reconfiguring the broadband device would be preferable, but I can't tell you how to do that. Refer to its documentation.

Hi,

The 1005 Error Messages (no Data for 10 secs) applies to any event that is an internet connection drop.

This could be removing an Ethernet Cable or turning Off Wifi on the Mac or the connection being reset for some reason.

If the Modem also routes and the Airport Extreme is also routing then as Linc says you will have issues.

Most routers or Modems that route that use the 192.168 range can have either a 1 or 0 next and usually a 1 in the last spot.

Linksys devices tend to have the 192.168.100.x range but the device then tends to be either 254 or 1 (either end of the range it could be)

Whilst 192.168.100.10 is a valid IP address it would be more likely to be a device getting a DHCP issued IP from a routing device.

I have a Fibre modem that does not route and then a router from my ISP

The device is at 192.168.0.1 and computers, iPhone, games consoles, Apple TVs and the Ethernet connections for On Demand stuff on the Satellite service all 19.168.0.something numbers.

Do you actually know which device has the 192.168.100.10 IP address ?

Thank you Linc and Ralph for responding. Besides the Airport Extreme, that has Network Mode="Create a wireless network" and Router Mode="DHCP and NAT", I have the following equipment:

Airport Express that has Network Mode="Extend a wireless network" mode and Router Mode="Off (Bridge Mode)" at IP address 10.0.1.14
Sonos Wireless Sound System with 8 components at IP addresses 10.0.1.3 - 10.0.11
NetGear VuZone Wireless Camera System with 1 component at 10.0.1.2

The Sonos Bridge and VuZone base station are connected via ethernet to my Airport Extreme. Years ago, I had a Linksys router that served 198.168.x.y IP addresses, but I switched over to Airport Extreme that defaults to 10.0.x.y. I didn't think any device on my network currently has a 198.168.x.y address. I tried to ping the address 198.168.100.10 that appeared in the console log, but no response. I unplugged the VuZone and will see if the reboot/Double NAT errors go away.

Hi,

SO the Extreme sits at 10.0.1.1
The Netgear item has 10.0.1.2

The Sonos items get the next IPs starting at 10.0.1.3 up to 10.0.1.11

The Express has an IP at 10.0.1.14

Presumably computers and iPhone have .12 and .13 and are wireless direct to the Extreme (as the Express has a number after this.)

Other Possibles.

A Computer that is Ethernetted to your Network that has a WiFi connection to another (neighbour's ?) network.

An issue that appeared in Leopard was when the Mac was Ethernet connected to the Network but then supplied a Share Network Connection over WiFi to another computer (See System Preferences > Sharing > Internet sharing).

These two computers tend to get IP in the "Self Assigned" range which starts 169.254.x.x

The thing in Leopard though was that iChat 4 could "see" the Internet Connection of the second Mac (when it should not have).

Double Nat does normally refer to when the connection to the Internet goes through 2 routing devices that are "in Line".

However as I have related iChat/Messages will have issues if it can see the Internet twice.

This will include Ethernet and WiFi connection to the same network.

I know that iPhones can create Ad-hoc Networks and share their Connections to the internet which may include their carrier's data connection.

I have not heard of this being a problem though.

Yes, we do have a group of other wireless devices (iPhones, iPads, etc) on the network that are taking up the other IP addresses.

None of the other computers intentionally has a connection to a neighbor's network. I'll double-check the state of System Preferences > Network > WiFi > "Ask to join new networks" box on my machines. I'll have to look up the equivalent setting in iOS, but my carrier charges extra for my phones to share their internet connections, and I chose not to pay for that service. I looked to see what networks are available to join, and they are all protected at this time.

Since unplugging the VueZone a few days ago, I have not seen any instances of the Double NAT. I'll give it a few more days, plug it back in, and see if the Double NATs return.

Hi,

You have mentioned two Airport devices one of which is Bridge Mode.

That still leaves a modem somewhere.

What make and model that and what IP address is it showing the first Airport device ?

Is Messages still dropping Video calls ?

I have been unable to find any of my devices serving IP addresses (except the Airport Extreme) or connected to other networks. Using Airport Utility, I can see all the wireless clients connected to the Airport Extreme and Airport Express. The Sonos is hard-wired to the Airport Express, but I don't see any of the Sonos equipment when I check with Airport Utility. There is a Sonos utility from which I can see the IP addresses of each of the audio components. Does this mean the Sonos Bridge is serving IP addresses? I have not seen any address conflicts between my Apple wireless clients and the Sonos wireless clients. The VuZone is still unplugged from the Airport Extreme. So far no Double NAT errors and no dropped video calls using Messages or Skype.

The Airport Extreme's LAN IP address is 10.0.1.1. All the others are 10.0.1.x, where x=3..19

HI,

If the Sonos Utility is showing you the IP address and they are in the range of the Airport device it is connected to I am sure they are like the other Airport you have in that it is a Bridged device.

From your earlier post it seems the Netgear Camera also gets an IP in this range which make it seem that the Netgear VuZone is s similar sort of bridge device.

However it is odd that removing this one item removes the reports of Double NAT.

It would seem that the next logical step would be to put back the Netgear item and see if the issue has resolved itself.

I just had another instance of the issue with VuZone still disconnected, so VuZone is not involved. In this instance, I had just finished a Messages video chat with my Dad. Messages was still running and the status changed to "Disconnected". I clicked on Safari and tried to load apple.com, and it was stuck loading the page. A few moments later, the Airport Extreme status light turned yellow, and the Console spit it lots of Double NAT and other errors. I checked the Wifi status in the menu bar and saw four wireless networks - all encrypted. A more moments and the Airport Extreme status light changed back to green, and everything was back to normal. I captured the Console log and will take a look for any additional info it it.

Hi,

And this is separate from your Dad's half-duplex issue ?

I have only just realized you are posting in two threads.

I cannot see any crossover issue between them though.

Try this.

Quit Messages if Open

Open Terminal (Applications/Utilities)

Once it has loaded the standard first Line then Paste the Bold text below into Terminal and hit Enter

/Applications/Messages.app/Contents/MacOS/Messages -errorLogLevel 7

This will cause Messages to launch.

It will also create a Log in Terminal whilst doing so.

It will pause and wait once th Buddy Lists are logged in (it may help to have them displayed if you are unsure)

It will tell your both the Computer's (Messages) IP and the External Address towards the "bottom"

Your LAN IP will appear backwards (my so called 16.0.168.192) in the second line about Bandwidth.

AS you can see in the last section about CommNAT it lists the External IP.

If the external IP is another LAN IP there will be two NAT devices almost certainly Routing.

Also try turning Off IPv6 in the Connection Method System Preferences > Network.

I tried the terminal command on my system, and the "External IP" shown (72.x.y.z) matches the IP address assigned to my Airport Extreme by my ISP as seen in Airport Utility. The local IP address in my "GotBandwidth" line is 28.1.0.10 = 10.0.1.28 (backwards as you said) which matches the address assigned to my Mac Pro as seen in System Prefs > Network. The external IP is not another LAN IP so I presume there is not a second device performing DHCP at the time I ran the command.

How do I turn off IPv6? In System Prefs > Network, it shows IPv4. I clicked on Advanced..., and it shows Configure IPv6 as "Automatically". But the only other options for IPv6 are "Manually" and "Link-local Only". There is no "Off" as there is in IPv4. The Apple article, http://support.apple.com/kb/HT4667?viewlocale=en_US&locale=en_US, mentions disabling IPv6, as though an "Off" should be present. Other discussions show some terminal commands that enable the Off. Is this what you intended?

Thanks, Will

Hi,

My fault. I keep forgetting the IPv6 option now has no "Off" as such.

Try the Local Link only setting.

I use the Local Link only without ill effect with other apps. (On the other hand I am not sure my ISP is using IPv6 yet either)

I am not aware of a logging process for the Airport devices (I have never had one myself)

Something seems to be triggering a reset of the LAN at least if not further Up the line.

The 72.x.y.z number - is this a consistent IP address from the ISP.

Mine only changes for things like power cuts or a very rare Reboot of the Fibre Modem. (i.e. whilst the ISP may issue IPs using DHCP at their end it can be very difficult to "lose" the lease on it even in breaks from your Modem or router - if that is handling the login to the ISP server.).

Yes, the 72.x.y.z IP address from my ISP doesn't change very often - similar to yours. I changed my IPV6 setting to "Link-local only" and give it some time to see of the Double NAT returns. Thank you!

After applying the IPv6 change, I see I now have an IPv6 address. Is that self-assigned? Do you see an IPv6 on yours too?
