Mac Mini Airport Problems

Hi,
My MacMini is disconnecting very frequently from my home network. Using my MBPI I cam access the internet. So I know the problem is not with the internet service provider or wireless router. I re-started the MacMini and try accessing my home network and get asked by my wifi network password. However it times out and boots me out. Ocassionally, when I manage to connect to the internet I check for Mac software updates but again it times out. Ii seems that the problem is with the Mac Mini Airport. Any ideas?

The values for the mini are very low.
This message gives guidelines for evaluating a signal-to-noise ratio (the signal value minus the noise value):
http://discussions.apple.com/thread.jspa?messageID=10329543&start=1
If your noise level is in the middle -90s (a very good value), that would give you a SNR of 10 to 17, which would be considered a low or very low signal. I think the explanation of the mini's connection problems is that it isn't receiving a strong enough signal.
There's a way to use a command-line airport utility to learn the actual noise level. Let me know if you want more details.
Can you move the mini or the base station so that they are nearer to each other? Is there anything on top of or next to the mini that might be blocking the signal that you could move? Can you try rotating the mini to see if that improves the signal?
The ultimate fix would be to connect the mini to your AirPort Extreme with an Ethernet cable, either directly or using some sort of "PowerLine" adapter.

    Apple TV mirroring issues even with Mac mini,airport extreme bought at the end of last year,and an iPad 2

    I have the same issue with ATV3 and iPhone 4S. Everything works properly, no buffering issues when watching netflix, vimeo, youtube BUT when I try mirroring even a small 15sec iPhone movie it stutters and buffers and results to a choppy playback..same with larger mp4 files such as 1-1.5GB, buffers forever and never plays, I just re-encoded the same movie to 700MB and plays perfectly..
    Why Apple, why?..so close..I can accept the bigger movie files issue, but not being able to playback properly an iPhone movie is funny..I recorded a movie with lower bitrate through Filmic Pro (Economy mode, up to 16Mbps)
    and plays properly.
    Is there an upcoming software update going to solve the problem or is it hardware related and therefore not fixable.
    Please don't reply with a network related answer, by 2012 we know how to set up our networks and everything else runs flawlessly.
    I'll apreciate a fast answer, we love Apple, but if it can't play an iphone movie (or a high quality movie from iTunes) it's just not up to my standards.
    Thanks again.

  • How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac

    How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac?
    The question pretty much says it all.
    I have a Mac Mini with an attached 3TB Hard Drive used for Time Machine Backups.
    I have an Airport Extreme base station which services that machine plus several others.
    I would like to backup my new iMac and a MacBook Pro to the Mac Mini.
    What do I need to do on the mini to export that hard drive so that it can be used as a Time Machine target from the other systems?
    All systems are running 10.6.8.

    Well you would have to do backups over a network which is much slower and has highest chance of becoming corrupt. I think your best option would be to get an apple time capsule to act as a network and back if thats how you wanna do that

  • My mac Mini has problem rendering images and video

    THE PROBLEM:
    My mac mini has problem rendering JPEG image. There are strips on the images. Other images such as GIF, PNG, TIFF, and BMP are displayed nicely.
    The images shown in the links below illustrate the problem:
    http://www.flickr.com/photos/terencewong/71481156/
    http://www.flickr.com/photos/terencewong/73360989/
    (Please note that this image is grabbed from my faulty Mac Mini and saved into TIFF. For uploading purpose, I converted it into JPEG on ANOTHER computer.)
    For movies, AVI can be playback without problem. But when it is converted to MPEG, it looks like an untunned TV channel.
    FIXES TRIED:
    I did erase and install 3 to 4 times using both the install disc and my Tiger Family Pack. All ended up with strips on the JPEG images and the generated MPEG movies.
    I've also tried to flash the firmware to 113-xxxxx-124 using ATI's october 2005 universal ROM update, however, the ROM Revision shown in System Profiler is still 113-xxxxx-116 no matter how many time I reboot the system.
    INVESTIGATION:
    Yesterday, I did some research and got to know that JPEG and MPEG are using DCT (Discrete Cosine Transform) for decompression. And the ATI Radeon 9200 chip provide such a transform on hardware basis, which free the CPU from doing something else. Feel free to point out my inaccuracy.
    HARDWARE SPECIFICATION:
    I bought the Mac Mini in the last Februray.
    The system Boot ROM version is: 4.8.9f1
    Display card is ATI Radeon 9200
    Chipset Model: ATY,RV280
    Revision ID: 0x0001
    ROM Revision: 113-xxxxx-116
    A POSSIBLE CONCLUSION:
    I suspect that it is this part of the chip (the DCT) that is faulty.
    Anyone know how to fix this problem?
    Many thanks!

    Assuming that your display is tightly connected, thus the problem is not caused by something as simple as that, the fact that a full erase and install has not removed the problem would, I think, point to this being a hardware issue, and given that everyone's mini (with the possible exception of some of the latest ones) has the same video chipset as yours, and do not suffer the problem that you appear to, it seems very likely that your mini has a fault which is in need of repair.
    If you have an Apple Store nearby, I would take it there to have it checked out - at the very least they should be able to replicate your problem using an in-store display, and if not, thusly suggest it's something external to the mini and concerning your display or something very unusual in the immediate environment of the mini. If you don't have an Apple Store in reach, I'd take the system to an Apple authorized service provider since at the present time it is under warranty.

  • Slow internet: Mac Mini - Airport Express - 2Wire modem

    I have SBC DSL, which came with a 2Wire wireless modem/router. I then bought an Airport Express and nicely networked a printer and two Windows XP Machine. The trouble started when I bought (ironically) a Mac Mini with a wireless (Airport Extreme?) ethernet card. The Mac has much slower download speeds! We're talking 150 kbps on the Mac, versus ~1 Mbps on the Win XP box.
    I'm guessing there is a magic setting on the DSL modem which will help. Any ideas?
    Thanks,
    Morgan Brown

    This problem lies with the Mac mini - there aren't any settings on the DSL modem that will fix this problem. I would start by having an Apple service center confirm the wireless interface in this Mac mini is performing properly (since it is still covered by the warranty).

    com.apple.NVDAResman seems to be a common problem, I think some have moved the kext to correct it... might search that out.
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • MAC MINI- Airport Connection cutting out regularly

    MAC MINI- 10.4.11 1.5GHz intel core solo
    My mac (above) keeps losing airport connection (to my BT homehub router-which is newish)- Has been running fine for years-changed my router-was still running fine for a few weeks AND NOW....keeps cutting out wireless signal for no reason. I have other macs/comps on same signal (nearer router also!) which are unaffected-only mac mini is... I have tried everything I can think of and been on forums etc all day...
    Cuts out-won't recognise my router- then after a restart it sometimes comes back on-sometimes just comes back on itself after an hour or so also.... When its on, the signal gradually loses strength till it gets to zero-then disconnects and won't recognise any wireless devices (it usually lists a few that are in my building)....SO- router is OK as other comps are fine- it must be mac mini fault- have had no software updates recently either-so really don't know what to do next! help!

    Hi,
    thanks for your reply-I have tried every channel possible (before posting my first post)- but like I say -it connects fine at first (sometimes-especially if comp has been shut down overnight)-then after about 15-30 mins the bars start dropping and then it goes and won't come back on... I know it is not the router as my other mac (which is further away from router and also is a much older computer) has never had any problems like this before and doesn't have any while the mini is disconnecting..
    I have tried everything I can think of and have spent hours and hours reading through other similar posts- but can't find anything that works....
    If the mini macs have a weak antenna then why has it been ok in connecting since I bought it (was one of the first mini's to come out) ? Do you think it gets weaker with age? Why is it ok for a bit then disconnects,then is ok, then is not etc etc ??
    Thanks for your help anyway-any other suggestions you may have would be greatly appreciated as I am about to throw it out the window!!cheers.

  • Mac Mini Sleep problem - help!

    I have a new Mac Mini 1.83 and a new Envision 22" LCD monitor and when I put the Mac Mini to sleep and click on the keyboard, the MacMini comes out of sleep but the display screen stays black. If I manually set the computer to sleep a second time and take it out of sleep a second time by clicking on the keyboard, then the display works properly. But I have to put it to sleep and make it come out of sleep TWICE before the Envision display works properly. Any ideas about this problem?

    I have that problem since Quicktime 7.1.6 update (or the Airport Update, can't say).
    When rebooting the display stays dark, but everything comes up fine. When I put in the Installation CD, the display turns on.
    (DVI-FullHD, as before).
    But after the "blank" screensaver gets activated, the display doesn't turn on again, not even using the CD.
    (Although everything else still runs fine.)

  • Newer mac mini airport utility can't work with older airport express

    Hi anyone who can help me out.
    I have a relatively new mac mini (2012), and a much older airport express. I can accesss the internet no problem, but I cannot use the airport utility to chane the password on the airport expres. when I try, I get this message "This version of AirPort Utility doesn’t support this base station. Go to AirPort Service and Support for more information." I have the latest version of Airport utility (6.3.1), which is supposed to work with all generaions of airport express. I need to change the password, but I do not have any of the original set-up disks for the airport. How do I fix this?
    Thanks for your help.

    Unfortunately, AirPort Utility in Lion and Mountain Lion no longer supports the older wireless "b/g" versions of the AirPort Express. This would include model numbers A1084 and A1088.
    Please locate the model number on the side of your AirPort Express devices to verify the version that you have.
    If you have another Mac running the Leopard or Snow Leopard operating system, you can use AirPort Utilty on that Mac to administer the older Express. A PC could be used as well.
    If you cannot use another Mac or PC, then you might want to consider trying an unsupported method to install an older version of AirPort Utility on your Mountain Lion Mac. No guarantees can be offered that this will be successful since Apple does not officially support this method, but it does seem to work for most users.
    See this thread for more details:
    https://discussions.apple.com/message/22940547#22940547
    If nothing seems to work, the final option....likely the one that Apple wants you to use.....would be to buy a new AirPort Express.

  • Streaming Content to Mac mini Unibody Problem

    My setup:
    AirPort Extreme (dual router) with a 5 GHz N and a 2.4 GHz G broadcast at the same time.
    The N network connects to my Mac Pro and my Mac mini, the G connects to my iPhone. I need the G network to control my Mac mini via hipporemote.
    I just setup streaming by turning on File sharing on my Mac Pro and connect as a user from my Mac mini so that I have access to all my Mac Pro.
    In iTunes on my Mac mini I'll just "Add to Library" and point to the stuff on my Mac Pro (rather than sharing iTunes library), like this I can have cover flow and grid view, etc. (whereas iTunes Library sharing will only give you the boring list view).
    As I said I am fairly new to this whole Networking between Macs, as the AppleTV did it seamlessly.
    And the Mac mini connecting to my Mac Pro is as well seamless. I had no problems streaming wirelessly 1080p content as MKV files, which was brilliant.
    But speaking of the evil eye, after I was so happy and posted that, everything started to be choppy, even my iPhone app mouse controlling the Mac mini.
    It's weird because for a whole day of watching high-def videos without as much as a single glitch, now it's all choppy.
    I think I missed something, and am trying to figure out what the settings should be to maximize the throughput through AirPort Settings or DNS, DHCP and all that crap which I'm forcing myself to learn now.
    My internet is 50Mbps, which is quite fast here in Canada but I don't think that should affect the home network should it? In other words I could create an ad-hoc network without having an internet connection and just have my computers share files through the N network?
    In any case I thought I might just ask for advice here and will also see if I find the problem and keep you posted. It worked very well for a whole day, so something must have happened.

    Hi,
    Do you have another Mouse to test with?
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    Any change on reboot?
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • How can I use screen share of my mac mini?  Problems validating

    I recently purchased a mac mini to act as my home media server for audio as my airport express was not playing nicely with my Peachtree DAC.  Anyway, I have set up sharing on the mac mini and can't figure out how to connect from my wife's Macbook, or her iPad.  (I use a PC, so would welcome advice if available on how to connect across platforms as well.)  My goal is to set up the mac mini without a monitor or keyboard connected to it and have it sit with our main stereo. 
    I am able to connect to the mac mini via my wife's macbook IF I ask for permission and I grant it from the mac mini.  However, I am unable to connect no matter what I try if I try to log in as a registered user.  I have tried to add her as a user to the mac mini, I have tried to log in as a guest, and I have tried to log in with a password but no matter what I try, I get an authentication error when I try to log in as an authorized user.  For more clarity, here is what I have tried:
    1.  Added authorized users on the mac mini.  I created a user name for "jeff", "maureen", and "lastname_maureen" on the mac mini and provided a password for each user.  "jeff" and "maureen" are just created on the mac mini, and "lastname_maureen" is the user name of my wife's computer.  I confirmed the passwords, and still am unable to connect.  I have allowed any user on the network to access screen share, and no matter what I do I get an authentication error.  Again, if I attempt to log in from my wife's computer by asking permission, it works fine but I can't figure out how to set up an account to login.  Please help.  Thanks!

    Have you tried connecting one to the HDMI output, and another to the Thunderbolt port (with the appropriate Mini DisplayPort-to-other connection adapter as needed)?

  • How to Connect my PC to Mac Mini Airport wirelessly?

    This may be more of a PC question, but I'm trying to connect my PC laptop to my mac mini.
    I turned on internet sharing on the Mini.
    I can see my Airport wireless network on the PC, it says I'm connected.
    I do not have a password enabled on the airport network.
    The PC browser says it cannot find the server and will not load a webpage even though the wireless network connection window says I'm connected to my wireless network.
    any ideas?

    I would unplug the AirPort Express at this point and see if you can get the Internet sharing with the PC configured.
    My Mac mini is connected to the internet by Ethernet cable to my ISP's gateway. I am sharing the Ethernet connection to two iPod Touches via AirPort from my Mac mini. These are the steps for internet sharing from Ethernet to AirPort. See if you have followed them correctly in configuring your kit.
    1. In Sys Prefs/Sharing I highlighted Internet Sharing (do not check the box)
    2. Share your connection from: Ethernet (from the dropdown menu)
    3. To computers using: AirPort (check the little box)
    4. Press the button AirPort Options...
    5. Name your Network
    6. I use Automatic for the channel
    7. I encrypt my network using a 40-bit WEP key
    8. For a non-Apple device you must use only a 5 alphanumeric character, 40-bit WEP password or only a 13 alphanumeric character 128-bit WEP password
    9. Press OK
    10. Check the box for Internet Sharing
    11. Answer any dialog boxes that pop up
    If everything on the Mac end is correct then the issue may lie with the PC since Windows is much more picky about how it is configured. Here is an article that may assist you in getting the PC correct;
    http://www.makeuseof.com/tag/how-to-share-the-internet-connection-between-your-m ac-and-a-pc/
    Other things that you could try is to name your network with a short name without spaces, such as your Apple Discussions User Name. Also create WEP passwords of only 5 or 13 alphanumerics. Some also suggest an All Caps password.

  • Mac Mini Airport Extreme - Cannot detect any wireless networks

    Hello,
    Last week my Mac Mini (Power PC)'s hard disk crashed. So I did a DIY replacement. I managed to re-install all the software, and installed all the latest updates.
    However, for some reason, the Airport Extreme is not detecting any wireless network after the re-install.
    My own wireless network router is a third-party, which has been working well for the last 2 years. My Window PC and laptop still connects to it fine.
    I can see the Airport icon but it doesn't how any detected networks (and there are quite a few in my neighbourhood). I did Apple Hardware Test and it shows the Airport card to be working ok.
    Any help would be wonderful!

    It still may be possible that the antenna wire is not placed properly within the Mini. Here are an excerpt of the DIY instructions for installing the wireless antenna. Hope it helps...
    - Make sure that the antenna cables are firmly seated in the mezzanine board.
    - Pass the antenna cables through the gap at the rear of the internal frame.
    - Carefully lower the internal frame down onto the motherboard. Make sure that the wires are routed to the right of the interconnect board.
    - Snap the AirPort antenna onto the black plastic column next to the rear port panel.
    - Tape the AirPort antenna wire to the edge of the DVD drive.

    Mac Mini G4   Mac OS X (10.4.8)   Sorry for the cross-post. I posted wrongly in Airport Express previously.

    Hi,
    Thanks for the reply. I saw the thread before I posted and I'm hoping this will be solved soon.
    The main thing that worries me is that in my case, the Mac Mini is not even seeing any networks - zero in an apartment block where there is at least 5 network on the air at any time

  • Mac Mini Mail Problem

    Hi - I recently bought a Mac Mini so that I could have a desktop and a laptop (I'd been using the Titanium G4 as both) and I have been having trouble with the email on the Mini. Right off, I should say that the G4 had 768MB of RAM whereas my Mini only has 512MB. But the Mini is 1.5 GHz versus just 800 MHz for the G4. (I clearly don't know which of those matters more in a situation like this.)
    Anyway, whenever someone sends me a large file now, it takes a dog's age to get it on the Mini. And while it's clearly downloading it in the background, it seems to ignore if I delete other emails, etc. For example, I might read 10 emails and delete them, and notice that I have wait for some attachment to download, and minimize mail in the interim. When I open it again, those same emails that I deleted are in my inbox again. Occasionally, I have gone to mac.com to delete files, and eventually my mail app notices this and deletes them as well, but clearly large files are causing a problem when they're sent to me.
    It's not a bandwidth issue, as my G4 handled large attachments way better with the same Internet connection, and continues to do so while wirelessly connected to it. My guess is it's the RAM, but I really don't know. Do I need to go out and double the RAM on the Mini to make this stop?

    Please follow these directions to delete the Mail "sandbox" folders. In OS X 10.9 there are two sandboxes, while in 10.8 there is only one. If you're running a version older than 10.8, this comment isn't applicable.
    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    ~/Library/Containers/com.apple.mail
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
    Log out and log back in. Launch Mail and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Repeat with this line:
    ~/Library/Containers/com.apple.MailServiceAgent
    Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
