Late 2013 Macbook Pro Retina 13'' Wifi Issues

Hey Grant,

Sorry I meant 10.9.4. I'll update my post.

For me the issue comes and goes! this is super weird!

Funny fact: I enabled BT and now the wifi is connecting all the time!

apple's stance is non-action as evidenced over these many few yrs

Thank you for your suggestion. I had changed my router's setting (specifically changed the wireless channel from Auto to 6). It worked so well 🙂

You got lucky. That is only a temporary solution if you have a lot of nearby networks competing for the THREE clear channels available. Sooner or later your neighbors will move to Channel six and fight with you.

The recommended procedure is to leave your Router set to "Automatic". When it is slow, cycle its power. As it powers up, it will evaluate the amount of traffic on each available channel. It will pick the least-used Channel, "Automatically". That will give you best performance, unless conditions change. At that point, "cycle the power to your Router" and it will choose the best available at that moment.

That is why "cycle the power on your Router" is so often step 1 in problem-solving these issues.

Well that's just great. Now my Late 2012 Mac Mini (OS X 10.9.4) started having this same issue today. All of a sudden it doesn't like its Bluetooth Keyboard / Magic Trackpad anymore, and loses its WiFi connection/Bluetooth keyboard when waking up. And no, it isn't a keyboard battery problem.

Great.

Bluetooth uses the same part of the crowded frequency spectrum already populated with baby monitors, cordless land-line phones, microwave ovens and all of your neighbors' Routers. But bluetooth does not use the same modulation technique, so it just adds noise.

The long term solution if you can see more than a few neighbors' Routers is to upgrade to a dual-Band Router, and use the 5GHz band. It adds several more channels, and they are wider.

This doesn't work. For me anyway. I had the issue on my router which is dual band (2.4 & 5Ghz networks). Scanning my local area there are no other 5Gz networks nearby. I've left the channel on auto and tried manually selecting several channels. The problem persists.

I've got the beta build of OSX Yosemite on a separate partition and when I'm using that, I don't appear to be having the problem. Hoping they've finally fixed the issue with the latest release of OSX.

Try doing a fresh install using an USB. I downloaded Mavericks [10.9.4] from AppStore yesterday and did a fresh install. I was having all the issues listed in this whole thread previously but after the clean install, I don't have any connection dropouts. I am having rMBP Late 2013 13".

Create the USB using the createinstallmedia option as specified in various sites.

(Sorry my screenshot is so GIANT!!! Don't know how to make it smaller.) I don't want to jinx myself but I upgraded to a dual band router last week and it has been connecting ALL BY ITSELF without me turning wifi off and turning it back on again. In other words it has been working like a normal computer should. When I go out into the garden it still connects to 802.11n because it's out of range of ac. And to tempt fate I hooked up my Bose Soundlink Mini which disrupted everything the first time and everything has been working smoothly for two days now. Now I have Bose and mouse hooked up via bluetooth. Hope I don't have to post in a few days time that everything has gone wonky again. Good luck everyone and the release of Yosemite can't come soon enough.

Your connection shown here is on Channel 36, (anything above 14 is in the 5GHz band. Channels there are wider, and there is far less interference. You have a really strong signal at -48, and you transmit speed is a phenomenal 1300. You have left all your neighbors and all your Bluetooth devices behind in the 2.4GHz band.

The new Router may also have more and better antennas in the 2.4GHx band, so that may work a little better when you are out of range of 802.11ac.

Thanks for the analysis Grant. The transmit rate is not always 1300 but it is usually 878 to 702 when I am sitting about 2 meters away from the router. I am connecting automatically for the past week so I think it is all clear. Thanks again.

After 10.9.4 the problem still persists.

Im using my mac normally and this is the log from a ping to 8.8.8.8:

It just starts to fail!!! to solve i need to turn wifi off&on

The wifi icon show that the connection is ok and also i know it is connected to the router. This doesn't happen with my iPhones and windows machine in the same network.

The BT is off and this happens 3 or 4 times per hour. It is quite annoying.

My computer is a macbook pro 13" retina, 8GB, 2.4Ghz intel core i5

I've found a solution to the issue. For me anyway Your mileage may vary. I'm sorry if this has been posted before as a potential fix. I'm not about to check 50 pages of posts to find out 😝

Solution

Delete your bluetooth plist file and reboot. This worked for me on the latest version of Mavericks and the Yosemite beta preview.

1. Go to your Mac's Finder.
2. Click on the File menu and select New Finder Window
3. Click on your Mac's icon in the Devices list in the sidebar
4. Open Macintosh HD (or whatever your Mac's hard drive may be named)
5. Open Library
6. Open Preferences
7. Find the file called "com.apple.Bluetooth.plist"
8. Move it to your desktop. It should copy there.
9. Remove it from the Preferences folder by dragging it into the Trash. The Mac will tell you that Finder wants to make changes. Type your password to allow this.
10. Restart your Mac.

Hope this works for you too.

Hello everybody. I recently bought a macbook pro retina 15" late 2013.

I have some wifi issues. For exemple, when I switch on my macbook, all my devices (macbook pro included) disconnect from wifi. I need to wait 1 or 2 minutes to reconnect.

I have some connection drops. It's not a big problem now but I'm afraid it get worse.

Any fix ? You think it's a hardware or software problem ?
