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

My ipad2 hasn't the problem. My ipad air has the same problem (slow wifi)

I had the two following problems on my returned Macbook Pro and the new iMac

3. Ping problem

4. No wifi connectivity after sleep

I rolled back to Broadcom BCM43xx 1.0 (6.30.223.74.22) driver and both problems disappeared

New Ping

22 packets transmitted, 22 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 0.956/1.189/2.167/0.331 ms

I noticed two differences

1. Wifi always reconnects after sleep but takes longer to establish a connection compared to Broadcom BCM43xx 1.0 (6.30.223.154.45) driver

2. There is a lot more information written in log. The message "kernel[0]: ptkThread: Sleeping!" is written in the wifi.log for every millisecond of sleep

I don't think this is a final solution. I just want to investigate if it is a driver issue and decide on returning or keeping the iMac

hey guys,

I think I posted my initial positive findings on my 2nd mbpro too soon.

after the last mails on this thread today  I started to doubt if my initial good browsing experiences with my replacing mbpro would be the same today. So I did some thorough testing today.  Finally had some time to really doublecheck everything.

Ping results still turn out to be very inconsistent and mostly very bad. Even at 2 mtrs from my router.

My old 2007 macbook pro has very good results all the time. The 2013 mbpro has bad results mostly.

Then I did some more testing at 5 meters distance...just browsing through some bookmarks.......and it turns out that the machine is behaving just like the previous one.

At 5 mtrs slow or no internet at all......ping results are very bad mostly.

Download and upload speed tests alongside my old 2007 model are always worse on the 2013 mbpro.

tried it at least 20 times.....

a software issue after all ?  Pfff spend about a week on this matter.....

Are you testing on 11ac, 11n or 11g? Everybody is testing on different networks in different ways, making it very hard to see whether people are experiencing the same problems or different ones. It would be helpful if more people would test on different protocols (g, n, ac) and the two different drivers.

You have a good chance that your latency issue will be solved if you take the earlier driver. That has worked for most people with an MBA an also for nirmalts and me (11n at work and 11g at home, but not 11n at home). However, this roll back might introduce problems with connectivity (ie not waking up after sleep) as the newer driver was supposed to solve that for the MBA, though I haven't had that issue at all.

Also, has anybody else seen differences in behavior between native Apple apps (Safari, App store, iTunes) and non-native ones (Chrome, Firefox)? In contrast the Apple apps, non-native ones did not show the latency problems for me on 11n on the newer original driver.

all day on windows, I've done a lot of testing, Retina 15 basic absolutely perfect. 20 minutes by OSX, 115 ms, 89 ms, 68 ms. the problems are in Mavericks....

I saw the same when I was testing in Windows XP running within a vitrual machine in Virtualbox. Everything seemed fine on Windows, but bad in the terminal on Mavericks (several tests run randomly after each other in Mavericks and XP). On the MBA thread, however, people also report latency issues running Windows through boot camp (so not in a VM).

Did you run boot camp or a VM? What was the network protocol (g, n, ac)? Do you perhaps have Chrome or Firefox installed on Maverick? I found pages to load fairly quick in Chrome, whereas these same page woudl get "stuck" at 30 to 50% in Safari.

I have bootcamp installed with Windows 8.1, it is perfect. I ping the router 1/2 ms, Chrome is too fast. Mavericks in chrome is better than safari but the ping router is stable on 60/70/90 ms. I use bgn connection, 300mps, Tp-Link Modem Router.

this is the stable result on windows 8.1 :

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.
