Insufficient Bandwidth to maintain Video conference
Sometimes when I use the video ichat it says insufficient bandwidth and won't allow me to video chat. I have changed the server settings and everything to 443. Other times it will work perfectly fine.
Any suggestions?
How can I tell if its my broadband provider? I tested it and it showed Download Speed: 30967 kbps (3870.9 KB/sec transfer rate)
Upload Speed: 12248 kbps (1531 KB/sec transfer rate)
I just don't understand why sometimes the video chat will work and sometimes it won't.
Thank you for your input I really appreciate it.

Request for Interpretation of insufficient bandwidth error
To iChat Discussions:
I have looked at many of the messages posted concerning the "insufficient bandwidth" error that I am receiving from iChat. I have implemented all suggestions and I am still having trouble.
I am using a capable Quad G5 with an iSight camera. I have all updates installed with Mac OS X 10.4.6. I am using iChat 3.1.4 (v432).
I always get the "insufficient bandwidth" error message when I initiate a video chat with the outside world. I can text with all buddies.
I see the three test sites (appleu3test01,appleu3test02,appleu3test03) with green video cameras (multiple),as well the other contacts on my Buddly List.
I am connected to a university wireless system. I can transfer files up and down at about 6 Mbps, so there is no bandwidth problem. The IT experts say there are no ports blocked and that all is well. I have the Mac OS X firewall turned off. I can video chat perfectly with buddies inside my building, but when I try to go outside, I get the "insufficient bandwidth" error message.
Following a thread on the iChat Discussions, I captured an error log for iChat. I was hoping someone in the Discussions could interpret the log results so I could diagnose the problem with connecting from to the outside world. I annotated the log with some information about when I did what, starting the line with a /. I used the command
/Applications/iChat.app/Contents/MacOS/iChat -errorLogLevel 7
from the command line in a Terminal session. The error log follows:
/ I started up iChat and everything came up normally

Quad G5 with iSight Mac OS X (10.4.6)Hi Gary,
Welcome To The Apple Discussion Pages.
I see that you seem to have done the Quicktime setting
094151.005637 Bandwidth based on QT prefs = 21474836
094151.261284 BWD: GotBandwidth: 1618529/10814842 (up/down) @[35.13.21.96:255.255.252.0]
094151.261318 BWD bandwidth: 1618 kbits up, 10814 kbits down.
It is the IP listed here that worries me.
You say you are on a Wireless connection to the University's service but you are showing a Public IP (One I would expect to see as part of the info)
Has the Uni given you a direct outside line as it were ?
Are you saying you can use Bonjour but not the AIM side ?
Or do you mean that you can call out over the AIM side and get back to Buddies in your Building but not others ?
I am expecting you to tell us that the set up is like this:
Uni connection to the internet (Server or modem) <-> 1 or more routers <-> Wirless connection <-> Your computer
With a domsetic set up you would have a Public IP at the modem. This may or may not pass that IP to the next device. At this point there would be a LAN set of IPs issued to the subsequent devices and computers.
LAN IPs are in three groups of numbers
192.168.xxx.xxx
10.xxx.xxx.xxx
172.(16-32).xxx.xxx (basically a subset within 172.xxx.xxx.xxx)
The IP you show here is not one of those.
It is possible that the Uni has decided to use there own choice of IP numbers for their LAN.
However I would still expect to see two IP's showing up for you. One Public and the IP your computer has on the LAN.
Can you tells what IP you see in System Preferences > Network > Connection method in second drop down and then TCP/IP tab ?
I am expecting this to be a NAT problem.
More info on how the Uni are routing you to the outside would be helpful.

Insufficient bandwidth downstream required???
I've seen this topic and and having the same trouble. both computers have been set at the 1.5mps and Ichat pref has none for bandwidth limits..
Still get the message and error that says: 2006-11-13 13:45:23 -0600: There is insufficient bandwidth to maintain the conference.
Detected 371 kbps upstream and 48 kbps downstream bandwidth; 50 kbps required.
How do I adjust or fix the downstream? It's always been working before and it's always to with the same personIs it possible to limit network access by others apps during your video chat attempt? For example, disable file sharing services and other activities that use your upstream bandwidth, then re-enable them after your video chat connects.

IChat 2.1 insufficient bandwidth msg
When trying to video chat I now get this error msg in ichat:
2006-02-04 08:30:33 +1000: There is insufficient bandwidth to maintain the conference.
Detected 48 kbps upstream and 217 kbps downstream bandwidth; 50 kbps required.
I used to be able to video chat mac to mac using old modem (dynalink rta100+), which has since died. Now I have a D-Link DSL-502T and cannot video chat. Audio and text chat both work fine still. ISP say there are no probs with my connection (256/64).
Has anyone else experienced this, or know how to fix? I assume it is in the modem settings, but d-link can't help.
iMac G5 Mac OS X (10.3.9) 512mb Ram iSightHi Ralph,
thanks for your assistance. QT bandwidth is set to match my speed and iChat pref is set to none. still no success.
Did speed test at http://www.ozspeedtest.com/ results seemed normal:
download: 211.3 kbps
upload: 59.62 kbps
As I mentioned in original msg it was working before my old modem quit working. Have been trying to connect to testers and my brother in UK, both did work fine but now I always get "insufficient bandwidth" error. I have tried with a few diff modems too.
I have tried to set up port forwarding and a static IP with no joy (thats if I did it correctly) and have been to your iChat site. I'm stumped!
Any other suggestions?
thanks Simon -
Good old insufficient bandwidth
i am going mad trying to figure out how to troubleshoot my "insufficient bandwidth to maintain the conference" problem. i have just moved from one side of north america to another, and i can no longer video chat with anyone using ichat, nor can i audio chat.
i have been reading the forums and trying the different fixes, but it seems that the problem is slippery one with no one solution. here is my particular setup, and what i have tried:
-powerbook g4 running 10.4.3
-ichat av 3.1
-isight
-aliant dsl service with 1.5 mbps download (i've checked using dlsreports speed tests, and i get 1157 kbps down/339 kbps up)
-comtrend ct-301 adsl modem (which is NOT configurable, according to my service provider)
-airport express base station with airtunes as my wireless
i've never had a problem using ichat until now, and only in this location. i know that the problem is specific to my isp, because i can use ichat audio/video just fine at work, in my old apartment (where i had cable internet), and at a friend's house (with dsl).
-i have tried every streaming speed in quicktime.
-my ichat bandwidth limit is set to none
-i've tried changing the login port in ichat from 5190 to 443
-i've tried plugging in directly to my dsl modem, rather than using airport
-i have firewall off
-my service provider tells me that they have custom built-modems that cannot be configured
-i'm reading the forums for any clue
-i cannot switch service providers, because cable internet is not supported in my building. besides, my property managers have a contract with aliant, such that only they can provide internet to my building
what else can i try?
thank you in advance for any help i can get.
powerbook g4 Mac OS X (10.4.3)Hi,
This is the first time I have posted to the forum, although I find myself looking for solutions here quite often.
I am experiencing the same problem as the inital post, and use the same ISP, the same modem, as well as airport express. I have tried all the same solutions mentioned (disable firewall, plug-in directly to modem etc.) with no change in results.
- I have an imac intel running 10.4.5 with ichat 3.1.2 and built in isight
- speed test results were 831kbps download and 272 kbps upload
I tried downloading IPNetMonitor X and scaned the ports as was suggested by Ralph Jones using the IP address of a buddy and received results which said no ports were blocked. I also successfully pinged the same buddy's IP address as suggested.
Here is the weird twist: I have tested ichat with this same computer at my workplace. We use the same ISP, with airport extreme, and it worked perfectly on the first try. The only difference (apart from the modem model number) is the fact that our account at work is called "highspeed" whereas at home I have the upgraded service called "ultra highspeed". When I upgraded to ultra, I did not receive a new modem- all I had to do was change my user name setting and reset my modem.
To further test my theory, I tried the ichat test again from two other locations, one using high speed and one using ultra, with the exact same results.
While I had my father's computer, identical to mine, here at home, I was able to video chat and audio chat between the computers without using Bonjour.
After a lengthy and frustrating discusssion with my ISP, they have told me that there is no difference with both services other than improved speeds, and that the problem is on my side of the modem, not theirs. I suggested that they send me a different brand of modem, but they don't seem to think it will make a difference.
I am hoping that this new information might provide a clue, or that other users might be able to offer more suggestions I could try. I'd love to have specific questions to ask my ISP, with hopes that it might lead them to explore the right avenues to help me solve this problem.
Thanks for any help! -
Insufficient Bandwidth continues ...
Does anyone still have this issue even with the latest version of Tiger and iChat? Some of my buddies I just can't connect with. This one in particular is based on 2 ADSL lines with 8Mb's downstream and 512kbps upstream so bandwidth really isn't an issue yet iChat continues to get in the way!
iChat has become a useless tool since Tiger, I'm so disappointed with Apple.
2005-08-17 14:21:48 +0100: There is insufficient bandwidth to maintain the conference.
Detected 0 kbps upstream and 0 kbps downstream bandwidth; 5 kbps required.Hi Ralph,
Thanks for posting, i just needed to let off some steam. Of course I've tried everything and more, even the venerable 510v4 suffers these bandwidth problems never mind VOIP routers.
Another issue I have I think concerns Apple base stations, I have two Extreme and Express neither can handle iChat, the complaint is "insufficient bandwidth". This is separate to my problem when connected to Ethernet where only some of my contacts are unreachable yet they can connect with others.
I wish Apple would just remove this bandwidth detection altogether and let people get on with it, good or bad quality I really don't care but constantly messing about with iChat and it's related settings is really getting me down.
I suppose I could use Skype instead but I'm pure blooded Apple I want this thing to work and it's just tragic that Apple has messed things up like this. I know lot's of people who have given up on iChat, I'm still hanging in there but only just!
Ok, rant over. -
Insufficient Bandwidth when trying for video/audio chat?
When my Dad is away, I like to talk to him on iChat.
When my Dad tries to invite me to a video/audio chat, it comes up with a message, saying: insufficient bandwidth to run this conference.
I have tried altering the bandwidth on Preferences, but it doesn't seem to work!?!?!
Any answers to my question?

IChat and "Insufficient bandwidth" for video chats
I have spent hours and hours trying to solve this problem, after having spent a lot of money for an iSight specifically for use with iChat, which I now find don't work together. I just made the switch from PC to MAC and have been nothing but amazed until this... Here I have to give a huge "thumbs down", though. Apple has really screwed this one up.
The error when trying to connect video is "Insufficient bandwidth to maintain..." and sometimes "A communications error has occurred".
If anybody out there, especially APPLE can help me fix this, I'd be very appreciative. Note that I had GREAT success with aMSN, Yahoo Messenger, and Skype (for the mic).
Based on lots of reading, here are things I've done without success. Note that I have a very good ADSL-2 20MB connection! The machine is a new Mac mini Intel core duo.
1. Set the QuickTime streaming bandwidth to below what I know the ADSL line can do.
2. Set port forwarding for all the ports I found in all the FAQs, Apple technical documents, etc., etc.
3. Tried turning the UPNP of the ADSL modem both ON and OFF.
4. Made sure there is no firewall.
5. Tried every setting for the video bandwidth setting in iChat.
6. Tried both .mac and AIM accounts. (You never know...)
7. Made sure I have none of the known conflicting software indicated by Apple.
8. Made sure that Apple Remote connections are disabled.
9. Upgraded to 10.4.7.
I have actually read that some people got around this problem by connecting their MAC directly to their ADSL modem and (presumably) turning off its routing functions. But what am supposed to do with my 4 other computers, then?
Apple, please FIX THIS! There are abosolutely tons of people with the same problem and no solution.
Mac mini intel duo Mac OS X (10.4.6)Ok Ralph... Thanks again.
When you said "two lots", I thought you may have meant that the DHCP server might be giving out IP addresses on two sub-nets (192.168.0.xxx, 192.168.1.xxx, etc.).
Since all of my machines have a static IP (except my business laptop, which I have to drag around to customer sites), I actually tried turning off the DHCP server to see if it helped. It didn't.
Also, I don't quite follow what you're saying about the NIC actually having two addresses (masquerading)... one from the modem and one from the DHCP. This should not be true, as it is the specific purpose of NAT to avoid this. Only the modem/router should really know "who is who" and relay packets appropriately.
The only pseudo-exception I can see for this is if the iChat software on the client and/or the AIM server is passing through the external/internal IP addresses as part of its data packets... ie., not in the IP headers to be handled normally by the NAT layer. If so, then this is just quite simply a design flaw in iChat... and a really stupid one.
One other point... Should I understand from your reply that if I set the modem up for "single user" mode (ie., turn off NAT and DHCP), then I would need to manually forward the right ports?

Insufficient Bandwidth STILL a Problem
I've followed the instructions listed here:
http://docs.info.apple.com/article.html?artnum=301641
Still coming up short. Can anbody provide some other trouble-shooting tips.
Also, I don't know if this is important, but I am presently in Rome, Italy and am unable to iSight with family in the States. I have family in different states, and they can iSight between the two of them, but I am unable to do it with either. Can the "internation factor" be the issue? And if so, why?
Furthermore, I get "insufficient bandwidth" for both video and audio.
Thanks to anyone who can help.
Tim
Powerbook G4 AluminumYou're welcome, Tim. Interesting points. And some new information..... ... it was certainly working fine just a couple of months ago.Then you can add the suggestions in How to get iChat AV working again to the trouble shooting possibilities I posted in my initial response.If something has that long of a page for trouble-shooting, then the system should be rebuilt, don't you think?I think the system is being rebuilt -- continually. Everyone, from ISPs to the Mac user, is continually updating and adding features to their systems. I believe that is one of the reasons iChat occasionally stops working. It certainly was for me.
After several days of trouble shooting last year, I eliminated everything but my ISP. After several minutes of probing questions and discussions, they finally admitted to me that they had installed new equipment and instituted numerous "improvements" the previous weekend -- the day my internet service stopped working. They made an adjustment, and I was up and running again in 20 minutes. These days, as it says in my How to get iChat AV working again checklist, checking with my ISP is early in the list.
For many of us, iChat AV really is plug and play. Apparently it was for you, too, for a period of time. However, with so much complexity in our individual systems, connection configurations, ISP operations, the very complexity of multi-party video chat capability itself, AND the occasional added complexity of changing locations (or countries,) there are a lot of things that can cause the system to occasionally stop working.
I wrote these lists to keep from forgetting any of the possibilities. However, nobody's system could be plagued by all of the problems listed. Consider only the items that might be relevant to YOUR system, and try them in the order your think will let you identify YOUR problem quickly.
Please let us know what it takes to get sorted.

Insufficient bandwidth to stream HD video
When using Amazon Prime to stream HD video content, I now receive a recommendation that suggests watching my HD content in SD due to INSUFFICIENT BANDWIDTH. Is this a fault of the AppleTV I own (2nd generation), my Airport Extreme router, my Motorola SB6120 cable modem, or my Comcast Professional Tier internet service. I've read that Comcast and others may be the source of this problem related to Netflix, Amazon, and other content providers. I need to know what to do to correct the problem, if there is a solution.
Check speedtest.net to see what your current connection is. Check that against the plan you're paying for. Is it the same, or close? Note: HD streaming needs at least 6mbps.

Getting message"insufficient bandwidth"when trying to connect ichat video
I have tried all the suggested tips.
I've updated software, changed quicktime streaming to my 256kbps dsl speed and I still get "insufficient bandwidth" message.
The other computer I"m contacting has same settings as mine.
Is there an apple customer service phone number I can call to get this issue resolved or can someone please assist me on the message board?
Thanks!
Anna
G5 Mac OS X (10.4.3)Ok Folks,
IS your Mac Firewall On ?
If so it will need to have the iChat Ports Enabled in System Preferences > Sharing > Firewall tab.
Select the New Button and add the ports after selecting Other in the top drop down.
http://www.ralphjohnsuk.dsl.pipex.com/page4.html
iChat, like other applications and games does not use the defalt ports that are open in your modem and or routers and need the ports opened there as well.
http://www.ralphjohnsuk.dsl.pipex.com/page3.html
If these are set then you need to make sure the Quicktime Streaming spped is set to your Download speed.
To go with this you also need to make sure that the setting in iChat > Preferences > Video section > BAndwidth Limit drop down is set to NONE - as the Bandwidth can be capped by this setting.

Insufficient Bandwidth driving me crazy!
I’ve read and followed the suggestions in all the discussions on insufficient bandwidth with iChat but I still can’t get it to work with certain people. I can chat with and see my friends in Chicago but not my family in the UK. We’re all using macs. Could someone please help me?
Mac OS X Version 10.4.11
iChat AV 3.1.9
I did a speed test: down load 1163 kbps, upload 1057 kbps
iChat bandwidth limited to 500 kbps
iChat server port set to 443
QuickTime streaming speed set at 1 Mbps cable
ISP: Current through an Asoko PlugLink Ethernet Wall Mount Model # PL9620-ETH
Do you need any other info that would help pinpoint my problem?
Thanks!
AndriaHi Tony,
Thank you for all your help yesterday! By the end of the day I'd have my fill of trying to get iChat to work and tried another program to video conference (SightSpeed). It worked right away and now all my family can see each other, no problem.
Thanks again for all your help and time,

How many users in a group video conference on iChat

How can I tell that AutoQOS config is adequate on a video conference switch
I have a Tandberg video conference bridge and gateway connected to a 3750 switch. The audio is marked EF and the video CS3. I configured AutoQos on the switch and trust DSCP on the ports. When we reach a large video conference of 25 or more attendies, we begin to have problems. The Tandberg starts to ratchet some of the video streams down, some to below 180kps, and the conference quality begins to suffer.
The only change to the default AutoQOS config I've made is changing the "mls qos trust dscp" on the uplinks, adding a QOS policy on the Tandberg ports to mark the video with CS3 and trust the audio DSCP (Tandberg had a bug that didn't mark the video packets) and adding
queue-set 2
priority-queue out
to the uplinks.
Will the default AutoQOS queue/buffer/SRR share and shape commands be adequate for 25 to 30 simultaneous video streams? We allow about 500k per stream.
I read through the 3750 QOS guide, but am a bit confused with the explanations of the queuing and SRR workings. I know that CS3 is mapped to COS-3, but don't know which queue it goes in and whether or not it gets shaped/disgarded when too much video is present.
Once I am sure that the 3750 QOS is working OK, and not causing problems with our large conference calls, then I'll expand my troubleshooting to the rest of the network.
I've attached a text file with the 3750 config, and 'show mls qos int statistics' that show the packets are being marked.I mistyped in my first post. I do indeed mark the video as AF41 (Cos4). It is the call control that I mark CS3 with the policy map to get around the old Tandberg bug that doesn't mark the call control.
So do you think the queue 3, where Cos4 goes to, is big enough to handle 30 video streams of 480k? If my calculation is correct that would be 14.4mbps of video on a 100mbps port.
With this config.....
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
...is it telling me that queues 1 & 2 get 10% bw, queue 3 gets 60% and queue 4 gets 20% bw and is shared? If that is correct than 60% is more than enough for 14.4mbps of video.
What happens if too much video overruns the queue? -
I'm trying to set up an iChat video chat with my dad.
We both have an brandnew iMac with iSight build in.
Both have an ADSL with more then 250kps upload (should be enough for ichat videoconferencing, isn't it?)
And still we get the warning insufficient bandwidth.
The same warning comes with audiochat as well.
Text chat works.
We tried to chet with the firewalls turned off.
So my guess is that it is the modem, either on my side or on his.
Best guess is his side as he has a wireless adslmodem/router.
But how do we check this and most important! How do we turn the firewall from the modem off?
We only need the firewall on our macs turned on and configurated well.
Ralph. Is was hoping to test my side of the iChat by trying a chat with you, but is your account AIM our .Mac??Ralph, thanks for the help so far.
My side seemed to be working just fine, considering the succesfull chat we had.
I'm now working on my dads side.
The firewall of the modem (Philips Wireless ADSL modem sna6500) is disabled.
For the macOSX firewall I've installed the same iChat exception as I have on my own iMac, and I've found those in another tread about insufficient bandwidth on this forum.
The test-chat with appleu3test01 works.
But a videochat with my iMac doesn't work. Not even with both firewalls turned off.
Any suggestions what to sort out next?
The settings for Quicktime are set to 256 kbps (the uploadspeed of the ADSL-connection).
The settings for video in the iChat preferences are set to 200 kbps (500 is over the 256 kbps upload).
I'm pretty much out of idea's.
Normally both connections are fast enough.
My dad has 256 kbps upload and 4 mbps download
I have 384 kbps upload and 3,3 mbps download
at least, that is what we are paying for. How can we check the real connectionspeed?
