Late 2013 Macbook Pro Retina 13'' Wifi Issues

I just got my Macbook Pro back after a repair session with Apple, the solution for the problem is that you need at least 20% free on you hard disk for Mac OSX to work well. It is really non-realistic solution because 20% is a lot of space of you only have 256 GB.

But my wifi issue and the hopefuly my kernel panics are gone, if I ping now I get this:

Well I've got a 500GB ssd and I have 405GB free, so 20% free has always been respected and doesn't seem related to my wifi problems.

I have a fix. Since this fix has been running, no timeouts for the past 2 days. To put this in perpective, just before I ran this fix, every hour or so, my internet connection would drop. It's a simple but effective applescript that I compiled into an app. The applescript is this:

tell application "Terminal"

activate

do script "ping -i 0.2 `netstat -nr | grep -m 1 '^default' | awk '{print $2;}'`"

tell application "Finder" to set visible of process "Terminal" to false

end tell

Here's the link of the compiled applescript for you lazy people out there:

It might be annoying to always have Terminal open, but it's worth it.

By the way, if any of you more advanced coders are nice enough to make the UI a bit better and like hide the dock icon of terminal while the script is running, I would be extremely grateful.

Reply your results please! 🙂

I created an automator app with the code for you. It'll keep it running without having terminal open and a gear should appear in the menu bar from where you can close the app.

I don't need the script since my conection stays on but I figured I'd wrap it for you this way. Hopefully it works for you ;-)

Thanks!

Here's the link to the app with monolu's automator workflow:

Edit: wait a few seconds after you open the app for automator to initialize. look for the spinning gear at the top in the menu bar like monolu said

i just got a new MBP retina 13' a few days ago and i was having similar WIFI issues. after trying almost all of the suggestions in this thread with no success, i have tried to change the authentication method from WPA2 to WPA, and i think that did the trick for me. i haven't got the chance to test it for too long yet, but it seems like it's working quite well.

currently my router's wifi settings are:

channel: 6

mode: 11n only

channel width 40mhz

max tx rate: 300mbps

hope this helps anyone.

chart courtesy wikipedia

Using a 40MHz n-mode channel in the 2.4GHz band gives you a signal shape like the third chart above, that takes up nearly half the spectrum available. If you have ANY neighbors in range, they are likley to use a Channel that overlaps Channel 6, and causes you interference. Did the Router choose Channel 6 on "automatic"? If not, it would be better to let the Router choose the Channel, or use Channel 1 or 11.

well actually i was having issues when the channel was set to automatic (but also when the authentication was set to WPA2). thanks for the tip though, i will change the channel to 1 anyway 🙂

UPDATE: channel 6 causes issues for me. changed to channel 13 and it's is working great again.

This is a fix that worked for me until apple acknowledges the problem and fixes it with a patch. Macworld also has written about this issue.

After two visits to the self-aggrandising 'Genius Bar' who either had no clue or did not want to acknowledge the problem I found this after searching forums. It seems like my problem occurred after linking my macbook to my Bose Soundlink mini and if i don't have it on, then the mac searches for the bluetooth connection and slows the wifi connection. I experimented with my bluetooth mouse by turning it off and the same problem occurred. If the mac is linked to any bluetooth devices and if they're not turned on, then the problem persist for me.

This is purported ot be a fix for "WiFi won't reconnect after sleep", especially if no Bluetooth devices are currently active.

The file in question is:

/Library/Preferences/com.apple.Bluetooth.plist

Copy to the Desktop (in case of problems) and drag the original to the Trash.

Restart and test.

Thank you, this worked for me too although dont know how long its gonna last.

This worked perfectly for me until it slept for an overnight... hate it when i have to restart again everytime when it wakes up. this is like there is no wake up or sleep function. but still thx for the solution though.

I'm running the latest seed and still having intermittent problems. Some of the suggested fixes appear to work for a short while, but then my connection gets flaky again. I suspect they don't really 'work', but the intermittency of the problem (in my case) causes false positives.

I've been reporting this problem (via the beta Feedback Assistant) once every day for the past couple of weeks. I'll continue to do this until Apple responds responsibly (a serious investigation with a software fix or product recall).

I'd suggest everyone keeps on Apple's back as much as time allows.

My connection is still hit or miss even after deleting bluetooth plist twice. The only thing that works is turning wifi on and off. Not good news that the beta testing is not working either. HOPELESS!!!! They either have to issue a product recall for faulty hardware or give everyone a 5 ghz apple airport.

the 5GHz Apple Airport will not work well either, at least for me it didnt. Also i asked around some more and every MBPr user that i have spoken to has some noticeable WiFi problems on some networks.

Since it works on windows it is a confirmed os x driver issue and none of the tricks in this thread will work.
