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

Problem still persists after Mavericks update.  Pings are "ping ponging" all over the place.  My thunderbolt ethernet adapter has perfect ping, but AC wireless connecting to a new Apple AC router is all over the place.

Hi all,

it seems I have been able to solve my WiFi problem with Late 2013 Macbook Pro 13 Retina.

In my case, it was not due to Wi-Fi power saving features, pings etc. but to a strange interference between Bluetooth and Wi-Fi.

I noticed that because casually I turned off my Bluetooth and istantly Internet became faster than light, when it was stucked only a few seconds before.

To solve my issue once and for all, I followed the instructions on another Apple forum (sorry but I cannot find the link again):

- Go to Bluetooth preferences

- Click on Advanced button

- Disable all the options there (all three of them)

- Click OK.

Done. Hope this helps someone else, for me it was a life-saver!

For me changing bluetooth settings hasn't had any effect, but changing my router to use channel 13 on the 2.4ghz band did help and I'm not seeing the sporadic periods of high latency+drops anymore.

PHY mode: 802.11n

channel: 13 (2.4GHz)

security: WPA personal

RSSI: -43

transmit rate: 130

MCS index: 15

163 packets transmitted, 163 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 0.671/1.467/22.427/2.589 ms

Sorry, I spoke too soon: 40 minutes later, I do see the issue again regardless of channel.

I had the same problem after upgrading to Mavericks, diggin in another thread i found this:

https://github.com/MacMiniVault/Mac-Scripts/blob/master/unicastarp/unicastarp-RE ADME.md

That amazing work by MacMiniVault team saved my day before I went crazy, please help the community spreading the voice...

"

I'm using a Netgear CG3000 from my ISP, who has locked it down with an outdated formware.

It's running 802.11 b/g/n, 40 Mhz, auto channel. I've tried cycling through all the channels manually, but untill now only 802.11g on the rMBP.

Just now I've tried enabling WMM in the router as per mshybut's post. Instantly the rMBP connected at 802.11n. Thanks dude."

I have the same Router, an your post helped. I enabled WMM, and now i run on 802.11n - Thanks

I am having the same EXTREMELY ANNOYING issue. My brand new rMBP has extremely slow internet connections. Pinging the gateway is extremely bad:

I am running all the latest updates.I turned off bluetooth. If I reboot the router, things get better for a while.

My iPhone/iPad connected to the same wireless router work just fine. I will test with my old 17" MBP tomorrow...

So FRUSTRATING....

Is there a known solution to this problem by now?

I am also the same situation , I have applied for a new machine to replace .

macbook pro retina 15 / cpu 2.0 ram 16GB , Taiwan

Would be great if Apple stopped wasting their customers time with useless replacements.. but they don't even read their own support forums.

I was turned off the Apple Magic Mouse  and my problems with slow wifi connection will be solved %( MBPro13 late 2013

Apple please, do it something with it!

same big problems with 13" MBPr late 2013 here :-(

Heres my ping:

Actually i have already returned an Airport Extreme Router, which was probably perfectly good. I did not suspect the MacBook being the culprit, especially since i have never had wifi issues with any other notebook or router. A bit disappointing apple..

should try using a HD HomeRun streaming live TV on Late 2013 MacBook Pro, stream keeps stalling every few minutes when the latency spikes kick in

even just loading websites, the throughput is great but simple network activites like ssh and just initial page loading seem to incur huge latencies using both official AirPort Extreme 802.11ac and other 802.11n routers

ok, i just read the complete thread and figured out that a normal ping is not representative on the MBPr models. The -i 0.2 ping gets me good results. Also i am not seeing any lost packets so far.

However, loading websites is slow. I have never had such slow WiFi with any other notebook, sometimes it takes several seconds until a page loads.

now i left the ping -i 0.2 running in the background, turns out i am getting lots of "request timeouts" in between the successful pings. Here is an example:

Eventualy it completely looses the connection, which can only be re-established by turning off wifi and then reconnecting :-(

Problem still exists with the latest 10.9.1 special release for the new retina MBPs.

My problem is, that i can't connect to fritzbox 7330 sl and a few other APs after resuming from sleep.

Only a reboot helps.
