I am so disappointed with Networking Stability in Mountain Lion

I have been using Macs since '95
I have Mountain Lion installed on at least 6 CPUs.
The latest CPU to the collection is the Retina MacBook Pro...
The Retina wont stay connected to a network for longer than about 10 minutes.
Then connections stops althought the Finder STILL displays the network shares.
If I turn on Bluetooth on the Retina I cannot connect to anything.
Generally it is impossible to have a reliabe network using Mountain Lion
At times it is blazing fast (1% of the day) the rest is just filled with network drops and slowdowns.
I use the Airport Extremes for my network.
I have tried anything.. Using another router, another W-LAN router, altering MTUs disalbling bluethooth and ALL peripherals.
New Network Locations. You name it..
NOTHING I do will render a network with even 40% stability.
This is the first time in almost 20 years that I am contemplating switching to Windows.
Please --- If someone has ANY idea of what is going on this most erratic OS that Apple has ever release, please tell me...
I am at a complete loss here.
Thanks

You are not helping at all. You are venting.
Would have thought someone with your amount of posts would at least have had one constructive suggestion,
Please refrain from adding posts to this thread. I am not reading them nor am I taking them seriously.
And man, if NO ONE would have those problems WHY on earth does THIS follwing thread have 32,000 VIEWS....
Get your facts straight.... PLEASE

Do you have them all set to the same channel or something?
Ehm... goto an apple store and you will find their network to be highly erratic as well...
Mountain Lion is NOT relible when it comes to networking. At all..
Nonsense. I don't go to an Apple Store all that often. My Mountain Lion machines work fine in all other places.
Even the Apple Care folks told me "we are AWARE of problems with networking in Mountain Lion"
Nonsense.
Perhaps YOU are not utilitzing networking on a prefessional level, meaning IT HAS TO WORK ALL THE TIME ;-)
It does work all the time.

  • Canon 860 Series (Pixma) Printer Problems with OSX 10.8 (Mountain Lion) – links to Canon Support Site with Drivers and Software with install tips

    After spending several hours sorting out Canon Pixma OSX problems here are my thoughts:
    Canon 860 Series (Pixma 868) Printer Problems with OSX 10.8 (Mountain Lion) – links to Canon Support Site with Drivers and Software with install tips
    Problem:
    - New imac and MacBook Pro 2012 (OSX 10.8.2) had a problem using Canon Pixma 868 printer on network and would not scan or print using Canon Pixma software (Pixma MP Navigator 2.1 & Photo Print), which has advanced scanning and photo printing functions. 
    - When I connected the canon printer to my imac, OSX 10.8.2 automatically downloaded and installed drivers for Canon 860 series printer. I could then add the new printer (select ‘apple menu’ / ‘system preferences’ / ‘print and scan’ / “+”) and printer would work while connected via USB but could not get to print or scan over network wifi. 
    - The original Canon 860 Series CD does not work with 10.8 and the manual / online instructions did not make sense (as based on CD install). 
    Solution:
    1) Install Canon Printer Drivers and Software (from official Canon site)
    Go to canon support site, review FAQ, then download and install following Pixma 860 Series software & drivers for OSX 10.8 (links see below). The version I downloaded is in brackets but check for updated version. Full instructions are below.
    Canon 860 Series Drivers & Software  for OSX 10.8 Mountain Lion:
    The base software and drivers needed for using Canon 860 Series on Mac OS X 10.8 (USB) are
    1 Printer Driver
    (Canon MX860 series CUPS Printer Driver Ver. 10.67.1.0 (03-Aug-2012))
    2 Scanner Driver
    (Canon MX860 series Scanner Driver Ver. 14.11.4a (03-Aug-2012))
    3 Network Tool
    (Canon IJ Network Tool Ver. 4.1.0 for Intel Mac (27-Dec-2012)
    Canon Software for using advanced printing and scanning functions (while connected to network)

    Downloads or FAQ
    If you have problems installing the software under 10.8, see the FAQ on Canon site. You will need to allow software installs from “unidentified developers by using “Control” Key or by changing your system preferences)
    2) Check Canon Printer and Software Working while connected via USB
    Once you have downloaded and installed drivers and software and restarted computer, check that the printer and Canon Pixma software (Pixma MP Navigator 2.1 & Photo Print) are working via USB.  Open the Canon IJ Network Tool App (Applications / Canon Utilities /IJ Network Tool / Canon IJ Network Tool App) and make sure you can see the Canon MX 860 series (xx.xx.xx.xx.xx.xx) and that it shows the correct SSID Wifi settings (under the Canon IJ Network Tool App ‘Setup menu’).  This is normally done as part of the automatic install but worth double checking
    3) Add new network printer using ‘apple menu’ / ‘system preferences’ / ‘print and scan’ / “+”).
    After you have checked USB printing turn off printer, unplug the USB cable and shutdown the Canon IJ Network Tool App.
    Then turn the printer back on and wait 30s. Then add a new printer using ‘apple menu’ / ‘system preferences’ / ‘print and scan’ / “+”). Once you select “+” (add new printer), wait 10-30s for the Wifi Networked Canon MX 860 Series printer to appear in the new window eg Canon MX 860 series (xx.xx.xx.xx.xx.xx) (Kind: “Canon IJ Network”)
    DO NOT ADD THE MX 860 SERIES BONJOUR SCANNER (the Bonjour Scanner is the built-in software, is not needed and often appears first on the add printer list).  The Canon scanner can be accessed used through the MP Nav EX Ver. 2.1.3 software (which has much better functions)
    You will now have two Printer Canon MX860 (USB) and Canon MX860 (Wifi / Network). Set the Canon MX860 (Wifi / Network) as default and test print and scan
    If the Wifi Networked Canon MX 860 Series printer does not appear, check the printer and make sure that the printer can see the wifi network. On the printer select Menu / Settings / Device Settings / Lan Settings / WLAN Setting List.  It should say WLAN Active, identify the SSID and have an IP address
    If the printer can not see the Wifi Network, plug the USB cable back in, then open the Canon IJ Network Tool App (Applications / Canon Utilities /IJ Network Tool / Canon IJ Network Tool App). Make sure you can see the Canon MX 860 series (xx.xx.xx.xx.xx.xx) and that it has your SSID settings (under setup), if it has this info, restart the computer and the printer and try again

    help

    That camera shoots H.264 in an .avi wrapper.
    You will have to transfer the files via the Finder.
    Get a free copy of MPEG Streamclip and convert them to QuickTime .mov using the H.264 codec if you are presumably editing in iMovie.
    Note that your list of video codecs won't look like mine as I have Final Cut Pro, but H.264 is definitely an option for you.

    How full is the hard drive that you are trying to save to? Not that it should matter, but have you tried scanning another document?
    Is the scanner plugged directly into the Mac? Try it that way.
    Disconnect all peripherals except keyboard, monitor, mouse and scanner and see if the problem goes away.

  • Hanging problem with Adobe CS6 in Mountain Lion

    I recently upgraded my retina Macbook pro to Mountain Lion and was having some trouble with Adobe CS6 apps hanging on startup among other things (including iCal crashing on startup)
    I did a clean install of Mountain Lion and Manually rebuilt my applications folder so that Adobe MAster COllection was installed freshly on a clean install of ML.
    Now it is still sporadically hanging when I try to open Photoshop, Bridge or other Adobe apps. The only thing that seems to fix it is a restart which is inconvenient when you're in the middle of work.
    ANy ideas?

    Thanks for this. I had heard of the fonts problem some people have had. All my fonts were freshly installed by either the system or Adobe when I installed Master Collection. Following your advice, I just verified every font and the only problem that showed up (as you had predicted) was a minor duplication which I corrected. So, it seems unlikely to be the fonts.
    As for your other point, I have been using Final Cut Pro X and that has worked fine. The only other app that has given me trouble has been Calendar which seems to get strangely stuck sometimes while it is updating. Makes me wonder if there's something going on with the network I'm using. 
    One thing I hadn't thought of was that it could be a problem with gfx card switcher. This seems unlikely but I'll try disabling it and see if that helps.
    Weirdly, today when I had this issue, Photoshop loaded up ok but then hung when I tried to load any file into it. Bridge wouldn't start at all. I didn't try the others. Yesterday I was having problems with Illustrator.
    Anyway, I see what you mean about it not being a widespread problem - which is why I started this thread. It seems no one else is having any issues. If anyone else knows what I should look for in my configuration please let me know.

  • Flash Problem With Safari After Downloading Mountain Lion

    I'm getting a persistent "Shockwave Player Error" when launching or resetting Safari . . . posting here because I upgraded from Snow Leopard directly to Mountain Lion and that's when the problem began.  I have a circa 2010 Macbook Pro with 2.2 GHz Intel Core 2 Duo, with OS X 10.8 and Safari 6.0.  I have attempted fixes in earlier threads (mostly regarding the same exact problem when upgrading to Lion), such as uninstalling Flash and reinstalling the latest from the Adobe website.  Also tried (temporarily) disabling plug-ins to see if it's flash-driven.

  • Itunes hangs with itunes match in Mountain Lion

    Right!
    I've seen all the "Itunes hanging" issues that Apple is choosing to ignore. So I'm adding my bitter experience to this too!
    I have:
    Re-installed Mountain Lion, tried to run the latest version of itunes, and pulled down my cloud stored library. It hangs itunes, then hangs Mountain Lion.
    I have:
    Created a new user, and tried to do the same....it hangs itunes...then hangs the computer.
    I have:
    Tried using the rescue partition, and it ....yes, youve guessed it hangs itunes, and hangs the computer.
    I don't have wirless on, and am using a network cable. I've tried using wifi....
    My machine is:
    Mac Pro
    Processor  2 x 2.8 GHz Quad-Core Intel Xeon
    Memory  12 GB 800 MHz DDR2 FB-DIMM
    Graphics  NVIDIA GeForce 8800 GT 512 MB
    Software  OS X 10.8.3 (12D78)
    I'm a film editor and photo-journalist hence the amount of ram.
    Allof this started when Apple released Mountain Lion.....IT ALL WORKED BEFORE!
    Can the developers figure out what is happening, or are they focusing their efforts on trying to create the next rich experience pioneered by Mr.Ives.
    Fed up with this, I used to be proud of using Apple, however, I'm starting to like the look of Windows 8.
    Any ideas?

  • 2010 Mac Mini display and network issues after Mountain Lion installation

    I just installed Mountain Lion on my 2010 Mac Mini, but now the display won't work and it isn't showing up on my network.  I have it hooked up to my TV (I don't have another screen for it) via HDMI.  Also, I've mainly used this computer by using the share screen function with my laptop, so I don't have a keyboard or mouse for it either.  The Mini is no longer showing up on my laptop's network list...  Any suggestions?

    I would see if you borrow a USB keyboard and mouse
    from some one, because otherwise trouble shooting the
    problem will be next to impossible as sometimes the fixes
    and diagnostics require the keyboard (PRAM reset, Hardware
    Test, etc.).

  • Canon iR7105, iR-ADV9065 with GX300 server, and Mountain Lion

    I am having no luck setting up two relatively recent, large and expensive Canon printers in Mountain Lion. The situations are different so there are two chapters to this wall of text.
    This is a fresh Mac, so it didn't have any 'old' Canon driver trash on it. I have installed UFRII 2.43 and PS 3.60 from Canon and restarted.
    The iR7105
    The iR7105 doesn't show up automatically in the Print & Scan add-printer menus. No problem; I go to IP, using LPD, and set it up there. (LPD access is enabled in the printer.) After that, I have tried setting it up with each of three drivers: a nondescript Canon iR7086-7105, Canon iR7086-7105 PS (US), and Canon iR7086-7105 UFR II (US).
    The nondescript driver results in no setup options for the printer, so I know there's  a problem. This is, however, the closest to a successful setup I have so far. In the print dialog I get finishing options that seem promising, including for our saddle finisher. However, the saddle finisher doesn't engage when I send the print job -- I have to assume this is because the print driver doesn't have a setup where I can tell it what model of  finisher it needs to talk to? Further, there are no options for printing to the printer's Mail Boxes, so I can't just send a file there and fix up the saddle stitch on the printer directly (a workaround we've used with various jobs in the past). However, after the job has run, I CAN go into Command Workstation 5.4.1.25 and adjust the settings on the job there, and then get it to run through the saddle finisher (or to the Mail Boxes). This is the best I have so far, but it's not very good.
    So I try to set up the PS driver. Now I get setup options and I can select the saddle finisher model. I also get a popup asking about unidirectional or bidirectional; I choose bidirectional because the printer is on a network. Also, setting it to unidirectional doesn't change what happens next:  when I do send the print job, the printer cheerfully spits out a dozen or more pages of single-line garbage instead of what I sent to print.
    On to the UFR II driver. Again I get setup options as expected when I set up the printer. Again, the print options are exactly what I expect as well. Unfortunately, the print job doesn't go through: I get an error that says, "Canon UFR II Printer Driver / Cannot communicate with the printer, or the printer is not supported. If the printer is supported, check the printer connection and add it again, then start Printer Utility to get the printer information." Well, the printer is pretty certainly connected, based on the performances above. It's also supported, if Canon's suggesting I should download and use this driver is any indication. Finally, Printer Utility gets printer information that looks quite accurate. Nevertheless, after all of that, actual attempts to print still get the UFR II Printer Driver error message, and no prints.
    The iR-ADV9065 and its GX300V2.0US server
    After installing all the Canon drivers mentioned above, the print server (Canon iR-ADV C9000s GX300V2.0US) shows up in the '+' drop-down in Print & Scan. Great, right?! I can configure the server directly and control the printer that way! Yay!
    Nope. I get a warning: "Some of the software for the printer is missing. You may have to reinstall the software to be able to successfully print." I click Continue, since that's an option, and then I get "Setting up 'Canon iR-ADV C9000s GX300V2.0US...' The software for the printer was installed incorrectly. Please reinstall the software from the manufacturer." This time there is no option except Cancel.
    What would be awesome now would be to know what software I need to reinstall. Since I just installed the UFRII and the PS software on a fresh Mac, I'm not sure what's missing.
    So, back to manually installing with the IP address. From this point forward the results mimic those above, with variations for the printer's specific capabilities. The best driver option is still the non-PS, non-UFR version, and that 'best' option still won't control the finishing units. I must go through Command WorkStation to accomplish that.
    Bottom Line
    Because I am so close to having these set up properly, but not quite, I feel like I must be doing something wrong. Something small and subtle, probably, but hey, maybe it's something big and glaring! Can anyone help?

    The iR7105
    The iR7105 doesn't show up automatically in the Print & Scan add-printer menus.
    The Canon print controllers do not support Bonjour, so using IP > LPD as you have done is the correct procedure.

    There's no problem. This is how the PPD works on 10.8. For older versions of PPD it was necessary to configure the options. But with the latest versions of PPD, it is assumed that all options are available, even when the machine may not have them or supports them.

    It is not a lack of being able to set what finisher you have installed. You just cannot saddle-finish with the PPD. This is only supported with the full driver, such as the UFR2 or PS, because you need the additional plugins that are included with these full drivers to get the additional functions.

    Again, this is due to the lack of a plugin to support the submission to the mailbox. So it is another limitation of the PPD.
    And with you sending the print job to the mailbox in the past, you would have been using a full driver - not the PPD - to achieve this.

    If you can connect to the iR7105 with Command Workstation, then you must have a Fiery connected to it, such as the imagePASS-S2. So this would explain why the UFR2 and Canon PS v3.60 driver did not work. The Fiery does not support either driver. They are for the iR7105 that is using its internal Canon controller. Not the optional imagePASS (Fiery).
    Now the issue for you with the imagePASS-S2 is that no 10.8 driver exists - the iR7105 was released in mid 2006. So you will have to use the Fiery Express driver, which has limited functions but it is better than using the Generic Postscript driver.

    Like the iR7105 with the Fiery attached, the GX300 connected to the ADV C9065 does not support the UFR2 or PS v3.60 driver. But at least there is a 10.8 driver available for this model. Here is a link to the GX300 page from Canon USA.
    Now with this driver installed you can add it by selecting the "Canon iR-ADV C9000s GX300V2.0US" that appears in the Default Add Printer view (and the Nearby Printers window). The driver should be automatically found by the Mac, meaning the Use menu will be set to the correct driver. This will let you print and use most finishing features of the iR ADV C9065.
    Hope the above helps you. Reply if you need more info.

  • XServe with Snow Leopard and Mountain Lion Clients

    Okay, bare with me, as I'm fairly new to the whole Mac Server world. I have learned a whole lot over the last year and I've been able to completely manage our 60 Snow Leopard Clients on our XServe.
    Last year, I came into an existing setup with ~60 clients running Snow Leopard and an XServe running on Snow Leopard. We utilize Server Admin and Workgroup Manager to manage our user accounts and our clients. We have over 300 users and utilize Portable Home Folders with our accounts.
    Over the last year, I've learned a whole lot about managing the system that is already setup. I've made quite a few preferences and file structure changes utilizing Server Admin and Workgroup Manager. After getting new hard drives in three machines, I learned how to re-image them and get them set back up with our Workgroup Manager. I learn things pretty quickly and have a pretty high technology aptitude.
    So, here is the predictament I'm in now...our county just purchased 31 new Macs to add to our network. These are running Mountain Lion.
    I have a few questions, and I'm not exactly sure where this post should have been. I think the major questions/issues I face right now include:
    Will I be able to manage the Mountain Lion clients utilizing our existing server and Workgroup Manager?
    We need our server to work seemlessly with the 31 Mountain Lion clients and the 60 Snow Leopard Clients.
    Once I get one machine setup correctly, I need to create an image of it so that I can then utilize this image on the other 30 machines.
    How do I create an image and then deploy it?
    Do I complete this step before or after I have setup the first client with Workgroup Manager?
    Also, am I missing something? I just want to make sure I'm not missing anything important in regards to getting these new workstations setup on our network.
    Thank you so much for all your help! Any information you provide is much appreciated.

    No, you don't need an new license.
    But the Mac App Store doesn't allow you to download software, which you originally bought on DVD. Logic Studio is/was only available on DVDs, while Logic Pro, MainStage and Compressor are available in the Mac App Store as inidivdual applications.
