Late 2013 Macbook Pro Retina 13'' Wifi Issues

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?

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 ...

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.

I had gone into the 'genius bar' which always denies knowing of ANY problems with their wonderful machines. When I showed him the MacWorld article about this issue he then admitted that Apple knew about it. Lying b******s. Anyway he said it was either a software, hardware or firmware issue. I said 'Gee, what's left? Underware?' He did say that it may be a security authentication issue with home networks since I had no problems connecting with the Apple store's open network after sleep. He also said that it would not make a difference whether it was a 2.4 or dual band router. My Google Nexus 7 connects wifi and bluetooth instantly on my 2.4 router with no conflicts.

monty88haynes-

Your computer is seeing the slower, more crowded 2.4GHz band, which usually indicates that is all that your Router is putting out.

You are connecting on Channel 11, which is one of only THREE Channels in this band. Typical top speeds here are 72.2 unless you use Multiple streams. It appears you ARE using multiple streams to get a Transmit speed of 130. Signal Strength (RSSI) of -65 is pretty good. MCS index of 15 says you are able to use the most complex modulation scheme available. Overall, this is a good connection.

Your Mac may be trying to find a different Network. To stop that, be sure you have Airport at the TOP of the list (not as shown below, because I use Ethernet as my main connection).

Be sure you have checked the " [√] Ask to join new Networks" box:

In addition, make sure that only the Networks you want to join RIGHT NOW are shown here:

If you often go to a different place and use a different Network, you should set it up using a different named "Location". A "Location" collects all the settings you need and can apply them in one click, for example, to turn on your Mac FireWall and connect to a particular network with its password (if any) when at Starbux.

Hi Grant,

Thanks for the analysis but I don't have airport and I have tried creating a Home network and deleting all the other networks but nothing works consistently like it should.

My screen shots are old, and the terminology has been updated from "AirPort" to "WiFi" for exactly the reasons you suggested.

Sometimes when folks are at wits end, and have already done all the right things, the desperation move is to use ( Assist Me ) > ( Assistant ) set it up again from scratch, being sure to specify a new "Location" instead of the default.

OR you read the signs and accept that the Mavericks WiFi driver on the current MBPr is a big ugly mess.

Ive also gone through two macbooks, several routers, clean installs, apple support.

Please somebody post a screenshot where i see the 802.11ac working smoothly and somewhere near its capacity. Show me and i will believe.

Add me to the list of people having this issue.

Macbook Pro late 2013

OSX 10.9.4

I'm connecting to a netgear ac wifi router. Confirms it's in ac mode when checking the wifi list and a transmit rate of 600Mbps (capable of 1.3Gbps mode but the range isn't as good).

The connection stops at random times or usually when I resume from sleep. The wifi indicator still indicates that I have an active connection but I get no traffic. Turning wifi off and on again fixes the issue for a while.

What I've done to try and fix the issue:

• Bluetooth off
• Booted into safe mode to run a check on the startup volume
• Created a new location in system prefs-->network
• Booted into recovery mode and repaired permissions/disk
• Changed channel on the router
• Changed wifi ac transmit rate of the router
• Changed over to the 2.5Ghz band on the router
• Changed wifi security type of the router
• Tried various wifi access points (My work and a couple of friends wifi connections)

I'm still having the issue after all of this and it happens on multiple wifi networks. As soon as the wifi drops I immediately check my iPhone and the wifi is still working.

Lets hope there is a driver update to fix this. It doesn't happen all the time but when you pay the premium for an Apple device you expect it to work or have these issues fixed quickly. Can't believe it's July and nothing has been done to fix this yet.

rhirons-

10.9.4 has some fixes for some of those issues. It has been generally available for about a week. Some users reported their problems fixed.
