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

My new MBPR's wifi is very slow and constantly drops the connection, although it is showing that it is always connected. If I restart the computer it fixes the problem for a little bit then it starts again. I have a 2012 Macbook Pro on the same network with no isseues, and I will have to use it sometimes just to be able to browse the web. Is there any way to fix the issue on the new Macbook?

MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9)

    Did you check with Option-WiFi on the MenuBar? Are you getting reasonable values?

    It sounds like your antenna may be disconnected:

    There is nothing wrong with the antenna.

    If there was a problem like this, how do you explain the excellent connection with the Windows driver? (Bootcamp)

    No luck for me using 10.9.4

    I installed it; rebooted; slept over night, and on wake up it does not connect to my 802.11n 5ghz router.

    This behaves exactly as I previously described the no-wifi-on-wake issue does.

     

    I have yet to try creating a new location or resetting the smc or pram. I will try those, and we'll see if it can maybe not regress afterwards as has been the case.

     

    Other than that Johnniecache have you tried something more rigorous than file transfer, like with http://iperf.fr/ ?

    Same here.  I installed the update while in France while on holiday with some hope that I would reconnect instantly when I get home.  Still get the wifi search taking a few minutes before it finds and connects to my home network.  Frustrating and infuriating that these Apple 'geniuses' can't work out a simple and basic problem especially since this latest update was specifically to address this wifi issue.  Hope they finally get it right with Yosemite but I am not going to bet on it.

    This is weird!

     

    10.9.4 fixed my problem but after a couple of days it came back!

    I tried to create a new location in my network settings but still no luck ...

    Mine connects sometimes and sometimes it doesn't.  Afraid to connect my bluetooth speakers which started the problems for me last time.  Anyone with an instant wifi connection AND bluetooth connection working at the same time?

    Bluetooth uses a different modulation technique, but the same part of the frequency spectrum as the 2.4GHz WiFi band. If your connection is already marginal, active Bluetooth can make it worse.

     

    What do you get when you hold down the option key and click the WiFi icon, like this:

    ALSO: How many other Networks do you see?

    That exactly happened to me in both 10.9.3 and 10.9.4, only 10.9.4 reverted to broken in about 8 hours.

    Whatever is the cause, it's probably very hard for Apple to reproduce and therefore fix.

    Funny thing is that i have also a macbook pro retina 15" late 2013 and there are no issues with BT on all the time.

     

    When i upgrade to 10.9.4 and I opened my lid the computer was already connected to my wifi, no problem. Nowdays it shows connected or the exclamation mark but no access, OFF/ON solves.

     

    My iphone works fine and i use "auto channel" Which is always set to 11 and when i checked option wifi . It shows as connected with good signal.

    How do I copy and paste my result?

    Hold down the Option key.

    Click the WiFi Icon.

    type Command-Shift-4

    drag over the part of the screen to be captured. It will be saved by default on the desktop as "Screen Shot <date>.at.<time>".

     

    Click the tiny camera Icon on the forum to insert a picture.

    navigate to the screenshot file and click on it.

    Finish and click Reply.

     

    >> or if you prefer, just copy down the numbers and re-type RSSI, mode, transmit speed and how many Networks.

    After trying several ways, the ONLY thing that worked for me so far is disabling Bluetooth completely. As soon as I did that, my rMBP stopped dropping the WiFi connection even when waking up from a deep sleep.

     

    It's definitely a Hardware Conflict that needs to be addressed, and it seems to be related only to the rMBP model, since I have coworkers/friends with Macbook Air or other MBP models that don't have this issue.

    Bluetooth uses the 2.4GHz band that is also being used by inexpensive Routers. There are only THREE clear channels in the 2.4GHz band, so if you see more than two other networks, you are directly competing with another Router for those Channels.

     

    Bluetooth uses a different modulation technique, so it does not clash directly, but will contribute to general interference in that band. A Dual-band Router is needed in crowded areas to give you additional clear channels in the 5GHz band and additional speed through the use of wider channels and more sophisticated modulation techniques.
