Last week the advisor informed me that Apple knows there is an issue with compatibility on some routers. He didnt give me a definitive list of what routers mavericks isnt playing nice with but he mentioned some routers brands from several existing cases with the same issues I was having. My router was an Linksys EA3500 and the another router he mentiond specificly was a D-Link, but i think there was more. After asking me for a bunch of info about my router's configuration, he adiviced me that Apple engineers were working on the issue but he was not sure how long it would take them to find a fix. I asked him if there were any routers that were not having issues and as you would guess he had seen no reported issues with the Apple routers. So I went out and got an Airport Extreme and have not had any droped connection issues since. My ping reponse times still suck, anywhere from 4 to 150 ms, but I have never had any dropout issues. My suggestion is that if you are having issues with your connection I would try it on a few other networks and see if that resolves it. Then either wiat for a fix or bit the bullet and replace your router.
Come to think of it, do you have any of this in writing? If Apple is admitting it can't get its (expensive) laptops' wifi to work with anything other than a few select routers, shouldn't it be supplying those routers for customers until they've fixed things?

Feb 24, 2014 2:05 PM in response to cb12394856by Rollj83,Yes and no, I have some correspondance that they are collecting data about my wifi router and others to determine the correlation between them and me providing updates about my issues and the steps I took to troubleshoot for the apple rep. The way the rep. explained it is that the wifi router issue is kinda hit or miss right now, meaning that they (apple) do not have any definitive answer on what make or model of routers are having issues. I just asked if there were any routers that were not having any reported issues and that is why I bought the Airport Extreme. I can provide you with more information if you would like (maybe outside this forum).

Feb 24, 2014 2:21 PM in response to Rollj83by cb12394856,@Rollj83: Thanks, I appreciate the offer, but I don't want to spend more on another router just now. I've ordered a cheap USB wifi adapter that I hope will make things tolerable until 10.9.2. If that doesn't improve matters, I'll take the MB to a store to see what they can do (unfortunately my nearest is a couple of hours drive away, and I can't do without my MB even for a day due to current work stuff).
As an aside, what is it with Apple and wifi? I remember they had a similar problem with one iOS version (5 IIRC?). They did fix it eventually (I had several calls from Apple engineers about it). But I've never had any other gear with wifi issues, ranging from cheap pcmcia cards (remember those?), to my current Nexus 5 (which for wifi access speed and stability knocks every Apple product I've ever owned into the proverbial).

Feb 24, 2014 3:25 PM in response to cb12394856by Rollj83,I completely understand and only bought the Airport Extreme because I got tired of messing with it (and it also was an upgrade to my previous setup, supporting the AC standard and beam forming goes along way in future proofing). I will say that the apple rep. was very friendly and always got back to me promptly trying everything in his power to help me out. I did at one point ask that if I purchased a new router and it did not resolve the issue, if apple would be willing to compensate me for the expense. For which he said that he might be able to send me an Airport Express, but given that I am now running upwards of ten devices off one router it didnt seem like a good idea to overload that old of a device. So I sprang for the Airport Express.
I certainly do not have an axe to grind with apple or the rep, and was merely sharing the additional trouble shooting step of trying your troubled laptops on different networks to see if that fixes the connectivity issues. From what the rep. told me, my case was actually one of the more mild ones and that some people were have wifi dropouts on a more frequent basis. As I mentioned my laptop only seemed to dropout after waking from sleep and it also seemed to make a difference if I allowed the laptop to fall asleep with the lid open or when I intentionally shut the lid. In most cases shuting the lid prevented the connectivity issues I was experiencing. Since replacing the router I have had zero issues (crossing my fingers) and will be very happy if this is the only one I have to deal with during the life of owning it. Coming from windows based pc's that have had issues that I eventually just had to deal with, even though they came with a similar $3k price tag, I am quite pleased with my purchase. But as you mentioned, I have never had any wifi issues on these other windows devices. To be fair though on the previous linksys router I had a 2 iphones, 2 ipads, and 2 apple tvs, in addition to a windows and linux pc, all of which had no issues. So you got me on why the macbook is the only one having issues. Maybe Mavericks? From what I've read Apple was pretty aggresive with the power saving features incorperated into the OS. I guess if they release a fix soon we will know.

Feb 25, 2014 1:23 AM in response to ShaneD90by rranon,I have a Retina 15" MBP, late 2013, since mid january.
Initally, wifi connection was fine. At a certain point (a couple of weeks ago or more) it started exhibiting all the issues mentioned in this thread:
- difficulty to reconnect after sleep
- intermittent disconnections
- very slow connection at times, I think because of problems in resolving names
- very high ping times to the router (an old Netgear with 801.11g network).
Other machines in the house connect without problems.
I tried various fixes suggested in this thread (and elsewhere), with no result. But, when I changed the ISP-provided DNS with google's ones (as suggested by someone in the thread), connection became just fine. It still has problems reconnecting after sleep, but now connection is speedy and ping times to router are ok, which I don't understand, because, AFAIK, the two things shouldn't be related. Go figure ...

Feb 25, 2014 5:04 AM in response to ShaneD90by qpWKZvukEPYagHXqFoiy,I have a Retina 15" MBP, late 2013.
The very high ping times to the router has something to do with enabled Bluetooth. I tried most of the fixes suggested in this thread -- with no result!
- new firmware: 6.30.223.154.63
- disabling all advanced bluetooth options
- setting the mtu to 1453
- creating a new network profile
- ...
If bluetooth is enabled I'm getting very high ping times. If bluetooth is disabled the MBP works like a charm and I'm getting pings to google with avg. 25-30ms. Just try the following things:
- check ping with bluetooth on > high ping times, wifi drops, timeouts
- open the bluetooth settings window > increased ping
- pairing of new devices like apple keyboard > increased ping
- check ping with bluetooth off
So please Apple, fix this!

Feb 25, 2014 7:59 AM in response to ShaneD90by Silvain24,I have the same problem, but as i bought my 13 inch Retina at the same time my new Airport Extreme, i tought it was a 8012.11ac bug.
You have already a topic here for this issue:
https://discussions.apple.com/message/22982610#22982610
In fact, after many tests here at home, it appears that when the connection is established at full speed (1.3Gbit/s), the latency is perfect, close to 1ms.
The latency is high when all the 80Mhz band can't be reach, i think it's a channel selection problem or load balancing mismatch in the ac algorithm.
Anyway, it's very difficult to reach the 1.3Gbit/s or you need to place your MacBook pro just in front the Airport and enough close, 1 meter max.
I hope it's just a firmware problem and Apple will solve the problem, because when you have a pretty speed fiber at home, it's a shame to have this kind of latency.

Feb 25, 2014 8:16 AM in response to cb12394856by Carl_UK,It is easier to blame router chipsets and non-apple related hardware however, you can prove the software driver fault by tethering (mobile hotspot) between a macbook pro retina and the latest Ipad Air, you will see the same latency problem and I can also replicate it with my Iphone 5S.
These problems all dissapear once you update the driver.
There may indeed be cases where the router is at fault, I would expect these problems to be in the minority of cases and it is simply the wireless driver causing the majority of the drama on this thread.

Feb 25, 2014 11:03 AM in response to ShaneD90by SvB1,10.9.2 seems to fix my problem. My Late 2012 MBP 13 Retina had awful ping on 2.4Ghz, though worked fine on 5Ghz. After updating to 10.9.2 I switched my Airport Express (1st gen. version) back to 2.4Ghz b/g/n. Here is the ping test:

Much better comparing to old tests. And I don't have "No Internet connection" messages anymore.

Feb 25, 2014 11:14 AM in response to Silvain24by cb12394856,No good here. Router ping times for my 4 week old MB Retina Pro are all over the place, and download speeds half either the cheapo Windows box or my Nexus 5.
Appointments made: Genius Bar next Tuesday, ACCC (Australian Competition and Consumer Commission) for Thursday (it's illegal under Australian law for Apple to knowingly continue to sell a faulty model).

Feb 25, 2014 11:51 AM in response to ShaneD90by qpWKZvukEPYagHXqFoiy,Same here, still high ping times after installing 10.9.2. Much more timeouts in the first minutes ...
unbelievable, apple :-/

Feb 25, 2014 11:55 AM in response to ShaneD90by SvB1,After one hour since update to 10.9.2 I can add to my previous post, that Transmit Rate drops sometimes to 5 and connection freezes for a moment, though connection is stable and I'm online all the time (Dropbox for example shows that it's connected). Before update my MBP could lose connection and some of my apps could go offline. Not perfect, but now better than before.

Feb 25, 2014 12:29 PM in response to ShaneD90by qpWKZvukEPYagHXqFoiy,So those of you who have high ping or connection issues after installing 10.9.2 -- is bluetooth enabled? I'm currently using an external wifi usb adapter which works like a charm -- constant ping, no timeouts. It has to be sth. to do with wifi / bluetooth interferences, i guess.
and regarding: 'issue is solved after installing the newest wifi firmware'
Firmware Version: Broadcom BCM43xx 1.0 (6.30.223.154.63) > still a lot of problems
