Q: Late 2013 Macbook Pro Retina 13'' Wifi Issues

Me too - troubles with WiFi conectivity with my Retina MBP, late 2013 issue - annoyed as evryone else - off to Genius bar!

I called Apple support they gave me a case number and sent me to the nearest service provider, will go there after the new year's break.

I am wondering if anybody here successfully repaired it, since the guy on the phone said he has the same model but it doesn't suffer from the issue. I was under the impression that all units are faulty.

Listen guys and gals, Apple may or may not be working on a fix but we have spent at least $1000 of our hard earned money on an Apple laptop expecting greatness and this is what we get.I find it truly disgraceful that Apple won't even acknowledge their customers when there is a problem and worst won't admit their mistakes.If we want to be noticed we must do something about so please everyone who has this issue submit your complaints http://www.apple.com/feedback/ . Also if we really want to be noticed we can all "ping" www.apple.com during the use of our Macbooks and other Mac devices. The way to do so is the following command:

ping -i 0.1 www.apple.com

this will ping www.apple.com unlimited times until stopped with control + C or close terminal.

If this is too much work to do every time you turn on your mac do the following:

-Open Terminal then go to Terminal Preferences

-Go to Settings then choose a Theme

-Duplicate set Theme

-Choose Shell

-Checkmark Run Command under Startup and type in or paste the command above

-And you are done everytime you Login/Turn on your Mac the Terminal will open and run this command indefinetly

Not only will this perhaps annoy Apple, it will also help your connection problem as it won't allow the Network Adaptor to be put to sleep when the lid is closed and keeps the WiFi snappy.

I hope this helped some of you and will help all of us with the problem to be noticed

I had the problem of WLAN not reconnecting after deep sleep. I tried all options I found in different forums to fix this (including clean install of Mavericks) and was about to return my rMBP. Yesterday, I did two steps as in this article http://howtoapple.com/mavericks-wifi-issues-fix/ to (1) Set Service Order and (2) Delete ‘SystemConfiguration’ folder. I am pretty sure I have tried this before, maybe not in this order and it hadn't worked. But now, the problem has completely disappeared.

The pings are normal (even without -i 0.2). The WLAN used to be in the connected state when rMBP wakes up from sleep. Now it is greyed out and takes 1-2 seconds to reconnect. But it network is always available.

I realized now that I also did another step (3) Disable Wake for Network Access. This seems to be the one that has fixed the problem. This however has the disadvantage that the rMBP is not available on the network after it sleeps.

Just for the record - before you try all of these snake oil remedies, do the following:

1. Reboot the computer into recovery mode by holding Cmd-R.

2. Launch Terminal from Utilities menu

3. Do ping google.com or whatever you do to check the network from there

The guy in Apple support suggested this to remove any interference of you current configuration. If it drops packets or anything - go straight to Apple service provider, which is what I am going to do now.

Evening Ladies & Gentlemen,

Jarvis has identified this issue with my 13" rMBP. If we disable WIFI and turn it back in again it connects fine. So I join you all in stating the obvious: Apple tries to conserve battery power by disconnecting from WIFI once sleep mode has been entered. There is a coding issue between the rMBP's ability to reconnect after awaking from sleep.

Jarvis is analyzing the script and will try to compute a solution. In the meantime, Happy International Hangover Day!

I have done what you said and some packets were dropped what does this mean??Is it a hardware issue then?

justin:

If you have another computer - run ping on it and compare. Normally both readings should be pretty much identical, if Retina has dropped packets or ping times differ - drag it to repair.

15" retina here, 16gb/1TB SSD.  WiFi goes away after a sleep.  Icon shows connected, but nothing works.

Interestingly tonight, I had an issue I've not seen before.  When I went to ping something, i got a timeout, but also a "could not allocate memory" error after every timeout.  I was using it pretty extensively the night before with many apps going (some consuming about 2 gigs of RAM) over two different user profile, and have been using it all day today as well w/o any issues -- wifi or otherwise.  But I hadn't seent that before.  A reboot fixed the wifi as well as memory allocation error.

Regarding the wifi, turning it on/off seems to always fix it.  It's not all of the time, but is certainly annoying.  My MBP was an ordered one and I had tracked it from China.  (Had to order it due to the 1TB SSD)

I am past the 14 day return window, but with the holidy return policy, I am considering bringing it back.  My older 2011 MBP 13 never had any wifi issues at all.

The ping times are also all over the place.  The 2011 13" MBP has no issues.  Side by side, same destination.  Drastically different results.  1-2ms on 2011 MBP versus 1-60ms on the 2013.  Just to the local router.

I'd gesture to say this is across all haswell-based machines.  My guess from reading through the forums.

Don't think I had issues with 2013 Haswell-powered Macbook Air which my wife is using now. And she is not complaining either.

Same problem here with 15" late 2013 mbpro 2.6 ghz.

When close to router seemingly no problem with WIFI. Altough I did not do Ping tests.....

At plm 5 meters very slow internet access with every browser or even no WIFI signal at all......

I have the feeling that it is worse when clicking links or seperate pages on a site.

Typing in a homepagename seems to load faster in the browser.

Do hope it is sofware related.

A statement from Apple that they are aware of the issue would prevent me to return the machine.

The genius bar is not the right place to find qualified people who can help fixing this I think.

Going there would be a waste of time , unless a replacing model would be the only solution.

Going from 2.4 ghz to 5 ghz on the wifi router solved the issue.

So it is software related is my guess.

only problem now is that other apple devices do not support 5ghz.........

waiting for a fix from apple to be able to use my mbpro on 2.4 ghz........

Just for fun, I decided to swith the network around, even thouh I know it's not a network issue.  I have an AirPort Extreme, although I don't normally use it for wireless and routing.  For giggles, I switched that on and gave it a unique name.  The MacBook with the wifi problem could see that device perfect and never lost a single ping.  However, seeing anything past it was really 'really' bad.  Many time outs and very long times. 

For comparison, my Early 2011 MBP connected to the same AirPort and saw no issues at all.  Everything totall clean.

The AirPort is running the latest firmware as well.

I'd hope that Apple is reading these forums, as I think this machine will go back, even though I really like it.  I use it for work and personal with multiple profiles.  I'm a failry heavy user so need something that is bullet proof reliable.  Network connectivity is my life (I'm a network engineer). 

If I find any other relevant information, I'll post it here.
