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

MadBeaverDK,

What wireless router are you using ?

Zakarados,

What wireless router are you using ? What settings have you set on the router ? 11g mode ? 11bgn mode ?

I think I found a fix for my problem, where my late 2013 13" rMBP wouldn't connect to my Linksys WRT310N router via 802.11n.

I found this:

Wi-Fi: Unable to connect to an 802.11n Wi-Fi network

http://support.apple.com/kb/ts3727

When I went into the Applications & Gaming --> QoS settings I found that WMM (Wi-fi Multimedia) support was disabled, despite the default being enabled.  Upon enabling this my rMBP immediately connected via 802.11n.  It seems this was solely preventing my Macbook and potentially other newer Apple devices (Retina Mini) from connecting to wireless N.

I saw this solution somewhere in another forum but didn't stumble upon my WMM settings until now.

Hope this helps at least a few of you!

I am using a TP-link router running 11bgn 20MHz only.

I got my replacement rMBP yesterday and no longer getting dropped packed and the pings are much lower than before. Happy camper now.

--- 192.168.1.1 ping statistics ---

1000 packets transmitted, 1000 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 1.307/37.929/107.619/32.388 ms

I spoke too soon:

While I am now able to connect via 802.11n on my late 2013 rMBP, all of my other devices wifi speeds suffer when WMM is turned on, as in going from 20 MBPS without WMM to 1 MBPS with WMM enabled.  Only the rMBP is not affected.

Here's a board where they discuss the unintended effects of WMM:

I'm using a Netgear CG3000 from my ISP, who has locked it down with an outdated formware.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

Just to let you that I am another afflicted by wifi issues...have tried a number of the suggestions on the post to no avail...Apple has also been no help...perhaps time to ditch the new computer and go back to the old one which actually worked properly.  I have requested a replacement from Apple but they simply want me to speak to yet another person...Apple products + Apple Care are not cheap...I simply want them to work.

Agreed. Take them in. The run around is why I only buy machines directly from an Apple Store with Apple Care. Good Luck.

I need to take mine in.

See your other post in the other thread.

Thanks

I'll join the club - had my new MBP for 4 weeks - wifi - pretty unreliable - really hope Apple are working on a solution and that it does not mean loosing my machine. Guess a trip to the genius bar beckons. :-(

I've got a Macbook Pro Retina (15", Late 2013). Seeing an identical issue at work, which is an Aerohive.

What is also interesting is that this appears to affect other clients. When I join the network - everyone suffers.

Not seeing the same issue at home, which is an older-generation Airport Extreme.

Just confirmed this as an issue on another rMBP Late 2013 machine. Large variations in ping times to the router, dups and dropped packets.

Regular MBP on the same network had no issues.

Well, I had to disable WMM again, as it caused havoc on my other devices.

Now the internet on my rMBP is slower than ever, and I'm getting dropped packages, which didn't happen before. Thinking on getting an Airport router. Anyone know if these work without issue?

This is my first Mac, and I got it as it's supposed to just work. I've been having nothing but trouble with wifi, and also there's issues with my WD Mybook Live and OS X in general. Come on Apple.

Yeah you would thik so but no. I have a new airport extreme router and it's got issues too. The latest firmware was a mess and I had to downgrade.

Also OS X Mavericks and WD are having issues. Western Digital has been posting news on their site. Basically uninstall their software entirely and be crazy careful.
