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 â–¹ 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 â–¹ 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.

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.

I have a rMBP, late 2013. After update to 10.9.1, I had constant wi-fi dropouts. I opened a Terminal and set up a constant ping to a remote web site and would watch it drop packets like crazy. Either had to wait for it to come back, or click the "Turn Wi-Fi Off" button in Network Preferences to turn wi-fi off, then back on for it to clear up. I use Time Capsule (7.7.2) for Wi-Fi and Backup, so went back to 10.9 and no longer have problems.
