    I've updated my tip.  It appears some corporate networks have an issue with Mavericks in general.

    Do you have this problem on other 5 GHz networks, or just the one created by your router?

  • jake0905 Level 1 Level 1 (0 points)

    hi,

    actually i am the only one around using the 5GHz network. all others are on 2.4.

    i am now on 2.4 without any dropout so far (20h).

    but performance overall worsened.

    I think the problem is due to incompatibility with your dreadful Linksys router, but you can try the following steps. Back up all data before making any changes.
         
    Step 1
      

    Take all the applicable steps in this support article. If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.

      
    Step 2
       
    Run Software Update and install all available updates for OS X or your computer's firmware.

    Step 3

    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.

    From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.

    If the application called "Bluetooth Setup Assistant" is running, quit it. Note: this is not applicable to OS X 10.9 or later.

      
    Step 4

    This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.

    Triple-click the line below on this page to select it:

    /Library/Preferences/SystemConfiguration

    Right-click or control-click the highlighted line and select

    Services Reveal

    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.

    *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.

    Step 5

     

    Reset the System Management Controller.

    Step 6

    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.

    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

     

    Keeping your confidential data secure during hardware repair

    *An SSD doesn't need to be zeroed.

    Thanks for providing your wireless router model. Linc seems to have a poor opinion of it. Curiously, when I search for it online, I can find no official vendor page for that device. Did you pay for it or was it given to you? Generally, any networking equipment provided by your ISP is going to be junk.

  • jake0905 Level 1 Level 1 (0 points)

    well, i am based in the netherlands.

    it might be that it is cisco at your side.

    after cisco took linksys over, they remain keeping linksys as retail brand.

     

    i consider my router as pretty pretty good.

     

    fully agreeing on the trash provided by your isps.

    that's why i got the linksys/cisco one.

  • jake0905 Level 1 Level 1 (0 points)

    this just can't be:

    using the router for at least 1.5 yrs with imac, mbp13 and mbp15 connected. never had any complaints.

    and right now it is only for the mbp15 that since the latest update shows these symptons. i was using 5Ghz band all alone and was very happy on it before update.

    my router model:

    After upgrading to Mavericks, my macbook pro(2.6 ghs , mid 2009) turned back to stoneage!

    I tried all the tricks and ideas, but seems like ill do a backup and just reset it and go back to snow leopard....

    At the moment i could just as well use a pc.... But thats too far!

     

     

    Ive heard a lot of people having problems like this with mavericks...

  • jake0905 Level 1 Level 1 (0 points)

    well, i must admit since updating to mavericks, i come across symptoms that just doesn't make me feel comfortable. recently even keychain resetted itself and i keep on retyping all those passwords.

     

  • bassrah Level 1 Level 1 (0 points)
