IMac :: Turn Off IPv6 For Airtunes - Will That Limit Other Things?
Sep 8, 2009
My airtunes was randomly breaking when trying to stream to my Airport Express and AppleTV. The dreaded (-15000) unknown error message kept appearing. Through searches here and elsewhere, I found a solution that has worked for me. I have turned off IPv6. System Pref >> Network >>Advanced >> TCP/IP >> Configure IPv6: set it to "off". It was on "Automatically" prior to my change. This switch fixed my problem with the airtunes streaming. My question is: Will this prevent me from fully utilizing anything else that my require IPv6? I'm not familiar with what that might be, or why we even need it. From what I've read, it's likely something needed or utilized on a large network, but at home, it seems unnecessary. Am I missing something or will I regret having to turn it off?

I have been having problems with wifi on my Macbook Air 4,2 and I wanted to try turning off IPv6. However, when I go to network settings to do so, the option to turn it off is not there. I've included a screenshot to show you what I see when I go to network settings. I don't know why this option would have disappeared. Is there a program that could have disabled this? Â

I gave my grandfather a macbook and he is bothering the @*&^ out of me with it. He keeps having wireless problems because he likes to play with it and whenever one of his dam sites wont load he thinks its the computers fault and messes it up. Is there anyway to remove the wifi icon from the menu bar and lock access to system prefs and anything else that he casn use to destroy the computer? I looked at parental controls and they dident do what i wanted.

I have a specific problem that I have tried to research and correct, but still no solutions. Here it is:
I currently have a wireless setup in my house using the IMac as a base station. I have this setup through the "Sharing" tab in System Preferences. I have an ITouch that I then connect to this network and surf the web downstairs, etc. It works great!
I purchased a new Airport Express that I want to plug in downstairs next to the stereo and then use Airtunes to play music over the stereo downstairs. This Airport Express would connect wirelessly to the IMac base station, just like the ITouch does. I also need to still be use the Itouch with this configuration.

Enjoying the speed of my new iMac i3 but the colors just seem way off compared to my older MBP. Perfect example is going to craigslist where the text is blue on my MBP but on my iMac the text looks purple. What is wrong here and what can I do to correct this?

I just brought a brand new IMAC 21.5" the base model (NVIDIA GeForce 9400M graphics) with 4 gb RAM. I downloaded the trial version of adobe cs5 to check if it runs ok but when I am starting things from scratch like just creating things from a blank canvas it runs so slow like trying to paint stuff and render it comes up with a loading screen it just doesn�t do it straight away. But when I am working on photos it seems to run ok. Is there away to solve this issue? Do I need to updated my RAM to make it run smooth?

Does SMB on Mac OS X share over IPv6 as well as IPv4? I would rather my sharing be limited to the local ipv4 and maybe 6 network, and not to the entire world. Are there any configuration settings I can play with in order to configure SMB in this respect?

I am using Macbook Air OS X Lion. I have been facing slow internet browsing problem from quite a while now. I checked the forums and found that lot of people are facing the same problem. Also found that disabling IPv6 or setting it to manual mode will help fixing the issue. But another big challenge is how to do it. I tried setting it to manual which would need router address, IPv6 address and prefix length which is supposed to be collected from your ISP. Unfortunately Comcast hasnt implemented IPv6 yet so couldnt find that information.

I am using free.fr in France, and IPv6 is enabled as part of the service. There are certain services running that were only accessible to the local network, but I now find that if I know the IPv6 address of the machine they are world accessible. I tried limiting services to be only accessible to the local machine, by adjusting the settings in the Firewall configurations in the system preferences, but the services still seem to be world accessible. Do the firewall configurations ignore IPv6? Is there any way to make it so that services are only available to machines in the local networks via IPv6. I suspect I going to need a command line tool or a third-party tool.

Why can't I ping my Lion Server via it's IPv6 address (using a tool on the provider's network) where IPv4 works all the time?

I am trying to get an older Macbook Pro running 10.5.1 online and it is not working. I'm currently using 3 other Macs on the WiFi network all running Snow Leopard, so I know that network works. I tried renewing the dhcp lease and I have it set to using dhcp and to configure ipv6 automatically, and there are 2 ip addresses under dns servers (I typed these in because they showed on my other MBP). I can't even upgrade the MBP because I have no ethernet cable and can't plug it in to update it. I can do to get it to work?Â

found today that 10.7.4-OS X doesn't handle IPv6-autoconfiguration.Â
At tcpdump I see the "Router Advertisments" but the configd can't answer with "Router Solicitation":
Jun 29 16:37:51 tksmac configd[16]: RTADV en1: send Router Solicitation: failed, Operation not permitted  All other devices in the same network works fine with IPv6 (autoconfig). Â

I don't know what the deal is. I'm trying to install 2 sticks of 2GB into my 7,1 iMac, and the screw just won't turn. I'm using a standard Phillips head, and nothin' doin'. The screw is now starting to strip, so I guess I'm going to have to take this into the friggin' Apple Store just to have them open the thing.

I recently installed an AT&T 2Wire modem (both wireless and ethernet). It setup OK and the wireless network works perfectly with my wife's iPod Touch. For years I've also had and Airport Express with Airtunes that I use to send iTunes to my stereo. I opened up the Airport Network configure panel and tried to add the Airport network to the 2Wire network. After several minutes, I got a response that said it could not join the network. After that, my Airport network disappeared. It does not show up in the Airport Utility and it doesn't show up anywhere. I have the original CD that came with the Airport Express, but I can't reinstall the software because it requires OSX 10.3 and I have 10.4.11. How can I get the AE network back?

I have tried many permutations: different settings on the AirPort Express, different configurations of Ethernet cables and Wifi, you name it. In every case, there are at least occasional patches of silence lasting 0.5-5 seconds (playback does not pause during this silence). My findings: If the AirPort Express is not plugged into the Ethernet, but instead forced to use the Wifi coming out of my AirPort Extreme nearby, then the glitches are almost constant. It is so terrible, during five minutes of "playback" there might be thirty seconds of actual sound.
If the AirPort Express is plugged into the Ethernet, it doesn't matter whether my MacBook Pro is plugged in. There will be occasional glitches. At least some of these glitches are coming from the MacBook-end, because they sometimes coincide with Time Machine backups or processor-intensive tasks. What the hell? Is AirTunes just bad? Or is it my MacBook Pro, is it overloaded or does it have some errant process stepping on the AirTunes' toes?

Three of the four LED lights inside the unit light up when the power button is press. When the power button is pressed I hear the chime and the front LED light turns on and the screen does a scroll and the front LED light turns off and a minute or two later the fans turn off.

My apologies if this is covered elsewhere, but I haven't been able to find a topic that answers my question - if there is one please let me know.
I would like to use my AE purely for remote speakers for itunes. This works fine if I select the AE as my network via Airport on my macbook, but then this means that I can't access my wireless modem and therefore the internet.
Any hints on how to select the AE purely for itunes and still be able to go only online?

I guess for the past few weeks, I wanna say since 10.5.3, the music I play through Airtunes has sounded crumby. Some distortion and crackling. I got a bit worried and thought it was maybe a HW issue, but tests and wavelengths turned out ok, and games/tv/movies had no issues. So I turned on Airfoil, to force all system sound through the AP Express and thus my sound system, and played songs back and forth, from iTunes and Airtines, to Quick Look/Quicktime and Airfoil. Lo and behold, Airtunes sounds nasty, Airfoil sounds perfectly fine.

I'm having trouble getting airtunes to play to my remote speakers. It worked as of this morning, but I moved the box to the other side of the room and added a printer. Ended up reseting the airport express. It's set up with a green light, but when I attempt to play music I get "An error occurred while connecting to the remote speaker.... An unknown error occurred (-3256)" etc.
I've upgraded the airport firmware, reset settings for AEBS and the express, restarted the computer, and now I am out of ideas.

So You like the Idea of being able to stream your music over wifi? but you don't want to pay 100$ for a aiport base station? and you have some "old" pc/macs sitting around?
I found the ultimate solution for you!
I tried to stream my music (use my old laptops as a wifi speaker station) for some time now, and I recently found Airfoil [URL] and it works GREAT!!! it even includes a video player which automaticly syncs the sound to the video(VERY usefull)
you only need The application, and another pc/mac, its really easy to set up, and you can not only stream iTunes music, but also any other sound on your mac!! I use it everyday, and I just wanted to share that, because i did not find any other solution!

I'm running airtunes from my laptop (wireless G) about no more then 12 feet away, theres a little lag when I change songs, at least a couple of seconds, If I get a wireless N- card will it make the in between noise go away, or at least become less noticeable?
