Late 2013 Macbook Pro Retina 13'' Wifi Issues

So I updated to 10.9.3, mind you that I had to get the wifi connected at home in order to do that right, which is done by toggling it off and on (regarding the stuck-wifi-on-wake issue).

After installing and rebooting into 10.9.3 (from 10.9.2) my Lat 2013 15" retina mac book pro did not reconnect to wifi. I again tried pinging the router locally, with no link, saw it thought it was connected to the ssid I have, and it got no traffic through for some 10-15 minutes until I rebooted.

I didn't zap pram, change settings, clear the smc etc. Just rebooted, and now with 10.9.3 which had that initial disspointment, it connected on bootup. And it has continued to reconnect every time I sleep and wake.

However I have not since rebooted again. Current up time (during which I've slept and rewoken about 3 times for 4-20h at a time depending, is 4 days, 12h and 15 minutes. I am affraid to reboot, or change any network settings, since, well, there's a chance it could behave again as it did on first boot, with the stuck-wifi-on-wake issue.

The only thing that's changed in the wifi details is:

CoreWLAN went from 4.3.2 (432.47) to 4.3.3 (433.48).

This might control how the driver is told to sleep and wake. It might not. That's a guess.

The other details are the same between 10.9.2 and 10.9.3: CoreWLANKit, Menu Extra, System Information, IO80211 Family, Diagnostics, AirPort Utility, All the details including Firmware Version on en0.

The router was not changed nor restarted during this.

I'll set a date for a couple months from now to remind myself to report back if stuck-wifi-on-wake has not recurred. If it has, I'll let you know sooner.

P.S. dantart, you have more networks than a single 100mbits fibre network. One of those networks is your 802.11n network you're using with your macbook, another may be the 1gbit wired network your router bridges your wifi network to which you may not be using, and your router routes packets to your 100mbits fibre network connection. Your wifi will never be capable of 1300mbits becasue that's an 802.11ac spec, but all people are saying is that were you using an 802.11ac network you should expect to get that speed because that's what you were promissed in the specifications of the machine you bought... personally I take issue with what they were saying too becasue no one gets the max speed in practice. We know that you're not seeing those speeds, nor the 600mbits max capable of your 802.11n network. We don't know for sure if it's congestion or interference on the wifi, the router, or the fiber connection to the internet. Those tests are never quite reliable. But we do see that yes, you've tested two different devices around a similar time, multiple times, and on average yes your older macbook is working better than your newer one, and it's probably totally down to the wifi network. I think the only question is what can anyone but Apple do about it? And some suggested some kind of consumer advocate suit process. Which is close to being able to do nothing.

Im in my vacation place right now with a 2.4GHz (802.11g) Network.

10.9.3 didnt improve anything. Same s**t, no reconnect after sleep, connection slows down and dies often when browsing websites etc.

On my 5GHz 802.11ac WiFi at home i dont have the problems described above, only the transfer rates are half of what they should be.

I bought my MBPr in Nov2013, this problem persists for 6 months now. No fix from apple.

Does Wireless Diagnostics (Option-click on the Wi-Fi fan in the menu bar) tell you anything of use?

its very kind of you that you want to help out, but this is NOT a problem caused by a user configuration or local network. I recommend you to read this complete thread, many people are experiencing these problems with all kinds of networks.

On the same WiFi networks, other products such as iPad, iPhone, older MacBooks, Windows PC, are not affected by these problems at all. Even the MBPr's are not experiencing problems when they run Windows.

Then it would make sense to try and narrow down what's different between them and the hundreds of thousands of people without any Wi-Fi issues on their rMBPs (including every rMBP in every Apple Store, as they're all connected via Wi-Fi and stay that way all day.)

There has to be a root cause, and often Wireless Diagnostics will report those things, e.g. Wi-Fi interference causing the rMBP driver to drop to lower and lower connection speeds to reduce net error/retransmission rates.

Just for the record, after applying patches, deleting plists Wi-Fi got fixed on my rMBP'13 but unfortunately not on my wife's MBAir'13. She is restarting Wi-Fi and complaining all the time and I don't know how to help her.

1. Every MBPr user i know has some problems with the WiFi. Surprisingly most of them accept it.

2. The problem has been narrowed down to the driver. Like i said, read the thread. I wont explain again.

Hi all,

I think I have the exact same problem with my late 2013 MBP, after searching everywhere I found a post (perhaps somewhere in this thread) that suggested turning off the bluetooth. I tried it just to see and it solved the problem. For my MBP, as long as the bluetooth is off when the laptop enters sleep, it is able to reconnect easily to wifi when it wakes.

This isn't a solution but it will remedy the problem until the drivers fix the issue.

(Also this was after an appointment with the genius bar that verified that everything hardware related on the mbp where working as expected. ) Hope this helps.

One of the recently-identified issues with BlueTooth is that users have allowed it to creep up on the list of Network Interfaces. It then becomes a candidate for a regular networking protocol, and your Mac chews up time trying to find out if it has a good connection to the Internet.

If you need to be using BlueTooth, make certain you have used:

System Preferences > Network > Press the little gear at the bottom of the right-hand box and "Set Service Order" to put Bluetooth LAST on the list of network Interfaces.

I had tried just moving the priority to the bottom of the list but that did not solve issue the wifi connection - the computer still searched endlessly unable to join unless I manually turned wifi on and off and reselected whichever network I wanted to join. So far the only thing that works is to keep bluetooth off, but it does work perfectly to keep the wifi responsive (unfortunately that is a problem for all of my bluetooth devices).

Well if you really think the issue is the Bluetooth network DUN thing, instead of just moving it down the list in priority (assuming you don't use it ever, like me) you can delete it from the list entirely. This is what I did when I setup a new network location that contains only thunderbold ethernet, usb ethernet and wifi in that order. That said under 10.9.2 this didn't solve any wifi-stuck-on-wake issue, until I moved to 10.9.3 with the same location. Caveat being that the first boot of 10.9.3 exhibiited the issue.

I don't believe there is a way to fix this at the moment. I have all of the updates and have taken it to the genius bar for their input. I do use bluetooth most of the time I am working on the laptop, however I can simply disable it after turning off the mouse each time and that fixes the wifi problem for now.

I am hoping that apple releases a driver update or some other solution that fixes this eventually however.

You can use Bluetooth devices like mice, keyboards, headphones, and headsets without needing to have either Bluetooth PAN (personal area network) or Bluetooth DUN (dial up network) as an option in your network settings.

I have this problem too on my rMBP 13" late 2013 8G/256GB.

First my wifi couldnt reconnect when the BT was on. So i turned it off and it started to work! Great.

Then after a couple of days. The wifi started to drop but the icon says connected.

No internet but local router page works!!

I went to the router page and checked "who is connected" and interestingly my rMBP is not on any list. DHCP table, arp, anywhere. So i renewed my dhcp lease and it started to work after a bit.

I guess that the problem is related to IP. I cannot confirm this works all the time. But at least i dont need to reboot the wifi anymore!

I find I turn on computer and I have to in most cases go to wifi symbol on the bar and click network preferences go to advanced and click on the click on my network, click ok and then force it in the network name. It is irritating but eventually works, but this is not acceptable for such an expensive computer. My ipad, iphone, and all other computers work fine on the network.
