Late 2013 Macbook Pro Retina 13'' Wifi Issues

https://discussions.apple.com/thread/5535320?start=195&tstart=0

Ok. Following my previous discoverings. I solved the problem of the dropping connections. 🙂

I read in another thread a post that somebody set up a low IP and it is what i did.

I have manual connection settings with this IP

192.168.2.2.

I also changed the router channel to the last one (13). It could be it is a channel with less users so less interferences.

I rebooted ( I think this is very important). !!

In my opinion the driver has a bug and once it gets blocked with the DHCP negotiation it gets blocked. I did what i explained and no dropping connection for one week. Not even once. But be sure to shut down the mbp no just suspend the system.

My network is 11g. WPA2.

In the other hand I'm having issues with the pings. Are very unreliable. Working always but with a lot of variation in response time. Not missing anyone but time has a lot of variation.

i can try to change my router with my old Netgear g Connection... if windows 8.1 is indipendent from Router, is a good result

i tested on both n and g.

where can I download the proper earlier driver?

I am on WLAN AC with Fritzbox 7490

The driver could be installed with headcase's instructions from here

https://discussions.apple.com/thread/5100655?start=1470&tstart=0.

followed the instructions but terminal won t let me. verystrange.....

anyway...more strange things to mention.....pings are ok now suddenly ...also at 5 mtrs distance from router, where I could not even get acess to the net this morning from this place.........

so behaviour is inconsistent.....gonna give it two more days of testing ..if it comes back...i will bring it back to apple and get a refund.

Could it be that there is some network activity in the background happening? The pings are ok when the network is active

Don't forget to save the original driver though. If the new one somehow doesn't work out, you need to be able to roll back.

Sounds like you may have some trouble with interference. Microwave? The neighbour's network? Depending on atmospheric conditions, these interferences may differ across time...

What doesn't the terminal let you do? Were you able to copy the kext file into the systems library (/Systems/Library/Extensions; this is not the library in your home folder!). The commands in the terminal are to change the access rights and the ownership of the new driver from you to the system (root:wheel). I suspect that the copying of the new driver didn't go right either, otherwise you would probably not have any wifi at all at the moment because the system would not be allowed to use the driver anymore.

You could do everything through the terminal:

1) First download and extract the new driver to your Desktop. You should get a file called "IO80211Family.kext" on your Desktop.

2) Now open a terminal window (in Finder go to: Applications > Utilities > Terminal)

3) Save your original driver to your Desktop in the folder "DriverBck" using the following two commands in the terminal (line by line; enter in between):

sudo mkdir ~/Desktop/DriverBck (the terminal will ask for your password after you press enter)

sudo cp -R /System/Library/Extensions/IO80211Family.kext ~/Desktop/DriverBck/IO80211Family.kext

4) Now only if the previous step went OK; copy the new driver from your Desktop to the Systems Library:

sudo cp -R ~/Desktop/IO80211Family.kext /System/Library/Extensions/

5) Change the access rights abnd ownership of the new driver (line by line; enter in between):

sudo chmod -R 755 /System/Library/Extensions/IO80211Family.kext

sudo chown -R root:wheel /System/Library/Extensions/IO80211Family.kext

sudo touch /System/Library/Extensions/

6) Reboot your system:

sudo reboot

thnx for that topfjoer

will retry tomorrow like u described.

I couldn't change the short howto anymore so here's a small addition/change:

A better (safer) way of copying the new kext file from the Desktop to the Systems Library (step 4) is:

sudo rsync -av --delete ~/Desktop/IO80211Family.kext/ /System/Library/Extensions/IO80211Family.kext/

instead of:

sudo cp -R ~/Desktop/IO80211Family.kext/System/Library/Extensions/

To roll back copy the kext package from the "DriverBck" folder to your Desktop and repeat steps 4 to 6.

I have this issue with my home network and it is seriously annoying.

I have tried everything: removing keychain entries, creating new network location, resetting the SMC and nothing helped. Using old MBA driver didn't helped either =(

Since many issues are getting discussed here it would be nice if everyone commenting here writes the problem and wifi type in their signature

For example.

[wifi g/n, wifi drop, ping latency, wifi sleep]

[wifi n, wifi slow, ping latency, wifi sleep]

In my case

[wifi ac, ping latency, wifi sleep]

I received a call from Apple (about my new 15" MBP, ironically same issue on my new iMac 27" over wifi). Sounds like they are working on a resolution to this and will send be sending me details about a fix they would like to test and it sounds like they are working on it for 10.9.2. Crossing my fingers. 🙂

I agree with nirmalts. Instead of just saying you have "problems", it would be helpful to explain the type of problem and the network you're on.

In my case:

Networks tested: wifi n (2x) and g

Issues: Ping and other software (eg Safari) latency. Haven't had any issues with drops or reconnecting after sleep.

Change to older driver solved latency issues on g and 1 out of 2 n networks.
