Airport Extreme 802. 11 b / g compatible mode does not work

Have a strange problem occurred recently on my home network. Here's what I have.

(1) Macbook Pro retina 2014 running 10.9.5 (must be this older OS for DAW/music applications)

(2) Macbook Pro 2009 10.11.1 running

(3) airport Extreme Base Station of 2nd generation

(4) Airport Express A1264 (1st gen N) compatible

(5) iPhone 4 s. IOS9.2.1

(6) iPad 2 8.4

(7) modem Netgear cable connected to Comcast

I have my Airport Extreme Base Station 802.11n value (802. 11 b / g compatible) and the Airport Express to extend the wireless network. Appliances mentioned above connects to the Station Base or Airport Express, according to what it is without any problems, except for my Macbook Pro of the retina's nearest.

It was not used to be a problem for the retina to connect to the network, it used to work every time but for some reason any in the past months, it is almost impossible to get the retina to connect to the network. At this point, the Base Station is less than 10 feet away from the retina and has a direct line of sight to it but the only way I can get to connect is by organizing the retina upward in the air on a dark corner and hope that it connects. As soon as I put it down again, the connection disappears.

What is strange is however if I go to the utility Airport and change options on the Base Station to one of the other 3 options, only 802.11n wireless (2.4 ghz), compatible with 802. 11A or 802.11n only (5 ghz) and restart the retina connects very well. The problem is my iPhone will not see and network, so I can't leave on any of these other 3 options I need my phone connected to use Skype etc. (virtually no cellular reception where I live).

It is a hardware problem at the level of the retina, something to do with the wireless antenna, or is IT a case of I need more recent material from the Base Station, a newer model that has more options?

I tried following the instructions from another post here remove all the com.apple.airport.preferences.plist etc etc files in the Library/preferences/systemconfiguration folder on the retina and reboot in order to restore the plist files but it does nothing.

Thanks in advance for any help/suggestions that anyone has to offer.

What stands out in your description is your AirPort Extreme 2nd generation base station. The typical lifecycle of networking hardware is Apple products around 5 years are in this group. The 2nd generation extreme was released in 2007 and stopped in March 2009... so yours is at less than 7 years.

That said, I guess that your Extreme is to his "last breath" and I do not consider it to be reliable in the future. You're already thinking that maybe this is the reason, and I second that opinion. Maybe it's time to replace it instead of making any additional unnecessary troubleshooting.

    I used the upgrade Toshiba Upgrade Wizard to Win 8. He succeeded well uninstall the incompatible software before the upgrade and install the new Toshiba and driver versions after the upgrade.

    I guess that the previous configuration was only Win 7.

    8 win was made for mobile (use of the Tablet), the energy consumption of battery is also very important plant help to win 8. The consumption of the battery must be taken at the lowest level possible.
    So I guess that now help win 8 ECO medium mode and save the power max and long battery life time working at a max level.

  • 802. 1 x authentication aid does not work

    According to the CEC documents, the following command should be a switch to do authentication for 802. 1 x for users. If this fails, the switch must fall back to no authentication. This prevents users to be locked to the network if the AAA/RADIUS server goes down.

    radius of group AAA dot1x default authentication no

    However, this command does not, at least not on the Catalyst IOS switches. If you disable the RADIUS server, the switch continues to try to use RADIUS regardless of the command above, even if the debugging indicates that the RADIUS server is dead.

    This directly conflicted with the following doc:

    http://www.Cisco.com/en/us/customer/products/hw/switches/ps646/products_command_reference_chapter09186a00801cdf12.html#1995856

    It is quite wrong that anyone who put implement 802. 1 x will be locked out of their network if the RADIUS server fails.

    Wireless access points do not have this problem because they can use a local RADIUS server. But it's a big problem for anyone with 802. 1 x running on cable networks.

    When Cisco will be be to fix this problem?

    Thank you.

    PAUL G.

    This does not work for 802.1 x and Catalyst switches.

    We will fix the documentation.

    In addition, Wireless APs don't have this problem with JUMP.

    Therefore, the challenge with Wired.

    Many EAP types, many types of back-end databases, etc. all need to review.

    We will have a configurable button in the near future to address, but as always, redundancy is recommended.

  • permitted in offline mode does not work since Java-Version 1.6.0_29

    Hi, our Appl. JNLP includes < off line-enabled > but on windows systems, it does not work if Internet is disconnected.
    He tries to go online again - and fails, see below: some of the resources required are not cached.

    I notice that any of our <>resources are stored in the Java Console "Resourses"!
    Of course: temporary files are allowed (1000 Ko), that the application itself is stored in the program!

    Someone has an idea, what happens? Java Version_26 worked perfectly.

    Hi Paul,.

    Unfortunately, I can confirm this problem too.
    That this regression has been already corrected in the version 1.6.0_01 report has been 6494357.
    Although the details of this bug may be different from what you get on screen the result is the same. The application works just not at all
    as soon as you are offline and when it uses the file extension jnlp.
    Once the access to internet is back, the application downloads again parts that still no change has been made.

    I fixed this problem by creating a unique jnlp without using any extension to this condition that works.

    It's not all...
    In windows XP, we can not use more the possibility to create our own progress bar, several new issues appear such as:
    The custom panel keep focus, which prevents the user to interact with all the windows open until the download is complete... (even the task managed to stop the current process)
    The values returned by the method of 'DownloadServiceListener' are bad or not properly refreshed. Sometimes the "read this far '" is heigher than the total ' to read '.
    When you have several Internet access, which means that Ethernet or wifi, you can not run a java web start application after spending between the two.
    You get two times a sign with an exclamation with nothing more. A little later, the Group deviation appears with more indication of a question on a connection delay.
    There is no other choice than restarting your computer.

  • Disable the setting of the play Mode does not work

    I have searched through the forum and with Google searches and saw he has discussed with several threads, but encountered no valid patches (or bypasses) so I thought I would try here...

    At work, I started in looking for a way to disable the 'read' for Adobe Reader X (version 10) Mode when the documents are displayed in a web browser, because a large number of users is complained about this.  I tried to disable (uncheck) the setting in the player 'Préférences', under the category of the Internet, but that has no effect on the way. PDF files are displayed.  I have tested this using multiple versions of multiple browsers (IE and FireFox) and ran on several versions of Windows (XP and 7).  However, even after unchecking the setting, the translucent toolbar still floating in the lower central part of the page.

    By clicking on the icon "Clover" ("see the toolbar Acrobat') to anchor the toolbar in a persistent horizontal row at the top of the window, which is what our users prefer, but having to do it manually with each document being read (which for some users, the number of hundreds per day) is extremely heavy.  In addition, unless I'm a bad interpretation of the description given by the Adobe documentation, that's exactly what the setting "Default playback Mode display" is supposed to control.

    Just for the record, here are other things that I looked at:

    • Confirmed that the [Adobe Acrobat or Acrobat Reader\10.0\AVGeneral HKEY_CURRENT_USER\Software\Adobe\] registry key, "bBrowserDisplayInReadMode", is actually used to 0 when the setting is disabled.
    • Tried to restart the browser, restart the computer and tried the test above under Windows XP and Windows 7.
    • Wanted by the release notes for each release / update of version X (10.1.1 10.1.2 10.1.3) to see if he had any information about it as a known bug, but found nothing.  Came across another post (http://forums.adobe.com/message/4087017#4087017) that claimed that the emitted are, indeed, a known bug that was supposed to be fixed in version 10.1.1.  However, my testing shows otherwise.
    • I have observed that even if the setting "Default playback Mode display" is not checked in the program settings (i.e. the start menu-> programs-> Adobe Reader, then clicking on 'Edit'-> 'Préférences'), if any. PDF file is then opened with a new browser session, not only is not docked toolbar, but if you right click and choose "Page Display Preferences", the parameter "Default playback Mode display" is checked.  Unchecking it, however, does not seem to have any effect.

    We appreciate any comments or suggestions.

    Again, I find answering me my own message / question.

    Apparently, this problem (parameter "Read Mode" has not influence) is a bug which is present in the version of Adobe Reader X 10.1.1 and after you have deployed the latest patch (quarterly), AcrobatUpd1013.msp, the problem has been resolved.  The parameter "Default playback Mode display" is managed correctly, so that the Reader toolbar is docked when the setting is off and returns to the floating, translucent toolbar / disappears when the option is checked.  It is more necessary to press the F8 key.

    Hope this info may help someone of another encounter the same problem.

  • blending mode does not work.

    I am unable to use the mix mode (screen) on my videos (shockwave) stock. He worked earlier but for some reason, he decided to stop working. He used to work with only the video layer stock alone, but now its not let me do blend with a single mode layer, now I have to use several layers for it to work. If I disable the other layer (not the stock of video) there is a black screen where the transparency is, as if it's a video of regular stock, same flood on the screen is activated. It's stupid because I just could, be able to have a layer and blend mode would continue to operate. Basically I can't use on a single layer blend modes as to make black become transparent. even if I could do a few minutes ago. Ive tried resetting preferences, Ive tried to restart the computer. With no luck. Someone help me please ():

    Here you can see that his game on the screen and the background is transparent but still black is not transparent.               Here, there is a red solid layer below the video of stock, which is on the screen. It works fine, but I don't want to have to add a solid layer, whenever I want something from the screen.

    You're wrong. The screen mode creates no transparency, it does that add some pixel values with a luminance value more high than black. Screen does not generate transparencies, never, never will.

    You can use Knoll Unmult to ensure transparency of the black areas in an image. It's easier work.
