Insufficient bandwidth - now solved - phew

I have just 'upgraded' to bt infinity. On trying to play bbc iplayer on an I pad I get an insufficient bandwidth message. How can this be the case, and what can be done to rectify the problem? I have also noticed extremely slow downloading speeds and connection keeps ripping out. Is this all part of the bt infinity experience or am I a one off ? I look forward to any comments
Solved!
Go to Solution.

FTTC is fibre to the cabinet - it's the technology used to provide BT Infinity.
Line training is not true, basically it'll work from day 1 if there's no faults.
Regarding your issue, it's probably a wireless problem. How far are you from the hub? Can you download the speedtest.net app and run a speedtest and see what you get? Once you've done that can you run a speedtest on a computer connected to the home hub with an Ethernet cable to see if there's any discrepancies in the results?

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!

Suddenly getting "insufficient bandwidth"

I do apologize if this topic has been beaten to death. iChat has been working wonderfully well for me and my friend, for a couple of weeks. Now, with no particular changes on either end, we are getting "insufficient bandwidth to connect".
Any help is very appreciated. Thank you. Darcy

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

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?

Insufficient bandwidth help please

Up until yesterday I was able to use bbc I player, stv player etc but I am now getting a message saying insufficient bandwidth. On checking my laptop they work fine. Why can I not get it on my iPad now?

Insufficient bandwidth with certain buddies

Well... it's the same old problem. I get the insufficient bandwidth error. Only with one exception: I get the error with only 1 specific buddy. I can't seem to do audio/vid chat with Buddy A, but have no problems with Buddy B, and Buddy A and Buddy B can connect with one another.
I have tried all the regular fixes (ie. QT bandwidth, checked download speeds, no firewall etc) and even re-installed iChat the hard way.
Still can't connect to Buddy A though...

I have a similar problem but we are all using the most current, 10.4.5, MacOS load.
I have a 15" PowerMac G4 HD with an iSight conneted and am trying to video chat with a variety of other Macs... another 15" PowerMac G4 1.67, a 15" MacBook Pro, a 17" iMac Intel, and a 20" iMac G5. My Mac and my friend's Macs are all connected to the Internet via broadband connections... some cable modems, some DSL, and one on an AT&T T1. Sometimes it works and other times it does not... It is sporatic enough to call it unreliable. We all have enough horsepower and bandwidth but for some reason the chats fail to start and we are treated with "so-and-so failed to respond"
It is ancient history now but when we all had Panther, iChat 2 and G4s this never occured... we started having problems when we all upgraded to Tiger and started getting G5s and CoreDuos... Not a very scientific observation and I'm not sure of the relevence.

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!
Andria

Hi 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,
Andria

Insufficient Bandwidth Linksys WRT54G 2.2

IChat 3.01 works fine if I connect my computer directly to my Comcast cable modem. When connected through the WRT54G I can text chat but audio chat attempts produce the dreaded "insufficient bandwidth" message. I updated the Linksys to v4.20.7. I have tried to open ports as listed in some of the other posts on this problem. I have selected Upnp enable, and Upnp disable. I have selected DHCP disable, and enable. I have reinstalled the 10.4.2 update. I have repaired permissions. In short, I have tried to utilize every fix detailed in the hundreds of messages offering fixes. Since iChat works fine without the Linksys in the mix, I am inevitably led back to the idea that somewhere I have a mistake in my Linksys setup. Has anyone got a setup guide for v4.20.7 firmware of the Linksys WRT54G that will help me step through each and every setting required to get this thing working? Or is this device just not going to ever work with iChat? Thanks in advance for your help.

I have the WRT54G (Ver 4.0/4.20.7 firmware). I have mine configured with UPnP only which opens the following ports: 1024 to 5000 Both TCP and UDP.
Try configuring it only with UPnP enabled(Take out all of the port forwarding and port openings, Unplug your modem, router, and mac and then plug them in in this order: Modem (then wait a minutes or two),router (then wait a few seconds), and then your mac and give that a go.
Then try testing with a known working screen account. (My screen name is in my profile if you want to test with me)
I've noticed the WRT54G isn't real good releasing ports from UPnP without rebooting.
That's how I got my WRT54G working and I can now chat with both Mac and PC's.
Hope this helps!
P.S. I have my mac firewall off.

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.

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 iSight

Hi 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

IChat w/ Linksys WRT54G- insufficient bandwidth error

Hi,
I am having trouble doing a video chat with iChat AV 3.1.5. Everytime I try to connect to a friend (using the same version of iChat) I get an error stating there is insufficient bandwidth. I have a cable modem connected over a linksys router and I am pretty sure my bandwidth meets iChat's requirements.
So far I've disable my Mac OS's firewall, disabled the firewall on my router, enabled upnp, diasbled upnp and port forward the port range I am using for iChat. Nothing has worked.
Any help provided would be greatly appreciated. I am at a loss about what to try next.
Thanks,
Lauren

i can not offer you professional support, only a solution (one of many) that solved this particular issue!
i have the very same router, except i don't have the "security enabled" new one. i read and read possible solutions, i tried them all and only one of them worked for me.
** access the administrative page at 192.168.1.1 i believe and log in (default is "admin" and "admin")
go to access restrictions, then look at the "DMZ" menu
change those settings to allow all the ports to accept incomming and outgoing, this also exposes your router to possible attacks. i guess when your done, close those ports from the DMZ menu, use this in conjuction with the ports settings in access restrictions (port forwarding)
this is a very tedious technique, but then again, iChat has some very stupid connection issues. this way may not be the best but it worked for me. if some else has a more permanent solution, please do help the guy.

BBC IPlayer - insufficient bandwidth message

When attempting to watch programs on on an Iphone or Ipad using the BBC Iplayer app, I select the program I wish to watch, press play, the screen goes black and the icon goes around until I get the message Insufficient bandwidth. This happens on every Iphone (4 or 5's using IOS 6 or 7) I have tried.I am able to download the program and watch it.
I am using a Draytek 2830n router on a 100mb fibre connection, I have sufficient bandwidth!
My ISP provider brought around a Samsung smart phone logged onto the same router it vworked perfectly. If I use a Mac laptop it works perfectly. If I use a Windows laptop it works perfectly It is only Iphones or Ipads that fail. This has been going on for about 1 month now. I took one of the many Iphone's outside the building and they work perfectly on 3G or logged onto alternative wifi networks.
The only other clue is that I also have Sky Go on one iphone and that says it's offline yet works outside the building.
It must be the router but am | at a loss to know what setting it is. Can anyone help?
Thanks, Smudger

Hi Etmoid
Sorry what I didn't explain is that I can log the phone(s) and IPad onto the router as you describe and browse the web, listen to radio through the Tunein app, watch "TV catchup" live TV and all the things you would expect from a wireless device. It is just the BBC Iplayer and Sky Go apps that are not functioning.as described in my original posting.
Thanks, Smudger

Beating a dead horse but...Insufficient bandwidth error on Tiger 10.4.6

So I'm running a new Macbook pro i just took out of the box, my girlfriend is doing the same. It's come with the latest version of Tiger. Here's the thing: with iChat my girlfriend and i get the all-to-familiar Insufficient Bandwidth message when we try to connect. I can connect with another friend on a standard Macbook, and my girlfriend can connect with me on the PC at my work, but we cannot connect with each other.
We're both running off of Cable Modem router wifi and have bandwidth of at least 750 mbps. I've been through the support pages, opened port channels, adjusted quicktime streaming preferences, but to no avail. Any more ideas or any other tips to get this to work. Visual communication was the primary reason for the purchase of these computers, and we're frustrated to no end that it simply will not work after troubleshooting.

HI theBen,
Welcome to the Apple Discussions.
At the ned of the day this can come down to the way your individual modems do NAT when using Port Forwarding, Port Triggering or DMZ and just not talk to each other properly.
This is because there are about six different ways manufacturers use to achieve NAT.
UPnP can help avoid this problem.
See here for more info http://www.ralphjohnsuk.dsl.pipex.com/page15.html#CertainBuddy
The iChat error messages are not always clear as to the exact problem and as you guessed ports can also be part of the problem.
