Late 2013 Macbook Pro Retina 13'' Wifi Issues

Here is the solution (below). Worked for me. I did the modifications in sequence up to and through turning off bluetooth. The author of the solution notes that this works for many people, and it worked for me. My fondest hope is that it works for many others. This Wi-Fi issue with Mavericks has been an incredible waste of countless users' time. The perfectionism and demand for excellence that Steve Jobs embodied is sorely missed.

@howtoapple fix: Nothing personal here, but isn't deactivating Bluetooth a bit like curing a nosebleed by head amputation?

I take it back: the fix was only temporary.

Christ, I'm having this disconnections again and it really ****** me off. I can't even read this thread without waiting for connection to reappear every 3-5 minutes.

****!

I got my MBP "repaired" through Apple. They returned it with a new network card. I turned on my macbook and after about five seconds of browsing, the same recurring problem returned. I am one extremely unsatisfied customer.

What do you get when you hold down the Option key and clcik on the WiFi Icon in the menuBar?

Mine looks like this:

.

Mode, Channel, RSSI and Transmit Rate can be very telling.

How many networks do you see beside your own?

You have a good signal strength.

The THREE standard Clear channels for 802.11g in the 2.4GHz band are 1, 6, and 11. Each one laps over two channels up and two channels down, i.e., 6 takes up 4,5,6,7,and 8.

With seven other networks visible, you are encountering massive interference. Your Router has responded by trying to use a channel "on the edge" of a real data channel.

I believe Apple has responded to the huge outcry at about WiFI problems by tightening their standards -- if the connection will be marginal, they do not connect.

The solution is to get out of the crowded 2.4GHz band and ADD or replace your Router with a Dual-Band Router. The additional 5GHz band will give you 8 to 12 additional clear channels, and your connection will be faster and more reliable.

I'll try that but I also have tried using other networks and I've replicated the problem at the Apple Store on their wifi. It appears that I can ping when my browser is closed, but once I open any browser such as G. Chrome, my ping speeds go down and they time out.

Hey Topfjoer!

I was having significant drops on my late 2013 rMBP running 10.9.2 then I tried your superb 'how to' on dropbox and my wifi now works significantly faster with no latency or drops! BRILLIANT 😀

Many thanks for going to the trouble of putting the 'how to' together and sharing with all, its brilliant! If only apple support were as useful and speedy as yourself!

To anyone interested in my set up:-

Late 2013 MRBr

2.8Ghz Intel Core i7

Mavericks (10.9.2)

Build: 13C64

Good luck to all and happy wifi driver fixing!

Thanks again Topfjoer!

webdude-

On you second run, your truly outstanding Signal Strength of -51 (from the first run) dropped to a poor Signal Strength of -76. That in itself could account for the decreased data rate.

In my old house, I have wire lath behind an inch of plaster, and the electricity was strung with armored cable. When the two touch (whilch is often) it turns the wire lath into a Galvanic cage and greatly reduces the WiFi signal. Then there are the chimneys, nearly four feet thick.

beley-

You are using the normally overloaded 2.4 GHz band.

You have a good signal strength at -53.

The THREE standard Clear channels for 802.11g or n in the 2.4GHz band. They are 1, 6, and 11. Each one laps over two channels up and two channels down, i.e., 6 takes up 4,5,6,7,and 8.

Your Router is set to Channel 10 -- "on the edge" of a real data channel.

I think you should check your Router and be sure it is set to choose a channel automatically. If one more Router pops up in your neighborhood, you will need to leave the 2.4GHz band and get a Dual Band Router, which can provide an additional 8 to 12 Channels in the 5GHz band.

When fix-it procedure suggest you should cycle the power on your Router, is sounds like a fool's errand, but it is not. When the Router powers on again, it chooses the available Channel that is most lightly loaded.

I can confirm that this was the solution to my issue. After trying nearly every other avenue suggested on these forums, the solution was using an older driver. Thanks Topfjoer for pointing out the real answer.

In my case I was okay with my browsing speed and downloads have never been terribly fast (rural DSL). What tipped me off that something was seriously wrong was a) Time Machine backups that never came close to completing (with only 100GB to back up), b) transfering a 23MB project folder to my 2006 Mac Pro took over a minute c) No changes to AFB/SMB or any other related file transfer settings made any difference in transfering data between the MBP and either my 2012 Mini (Mavericks) or my 2006 Mac Pro (Lion).

Good find!

I followed the last part (A how to) of headcase's description here: https://discussions.apple.com/thread/5100655?start=1470&tstart=0.

But before copying that .kext file into your system library, make sure you save the original one somewhere else before overwriting it. That way you can always roll back - which is the same procedure...

After installing the MBA driver this is what the description under Network/Wi-Fi in the system report says:

Card Type: AirPort Extreme (0x14E4, 0x112)

Firmware Version: Broadcom BCM43xx 1.0 (6.30.223.74.22)

Older drived didn't help me. So I had to buy $30 thunderbolt to ethernet adapter and 5 meter ethernet cable to keep working on my macbook.

Well done Apple!!

Hi to everyone,

After solving the "wifi takes too long to reconnect after sleep" related someway to bluetooth I began experiencing wifi drops and I did the following ping tests:

* bluetooth off: 0% packet loss

* bluetooth on and mouse paired: 1,5% packet loss

* bluetooth searching devices: 33,8% packet loss !!!

After that I found this thread and I`ve tested the driver "downgrade" suggested by Topfjoer (page 16) and it solved my problem.

Now I wonder if other people having this problem had also a bluetooth device paired.

thanks

Bluetooth uses the same part of the frequency spectrum (typically already overloaded) in the 2.4GHz band. I expect there WILL be a correlation, but only for those stuck in the 2.4GHz band with too many neighbors already.

The solution of getting a dual-band Router will cure BOTH.
