Q: Wifi problem since 10.11.2

Might be a router problem for some, not for me. I've got two Retina Macbooks at home, a 13" early 2013 and a 15" late 2013.

The 13" runs just fine on 10.11.3, the 15" model is unusable on that same version. I had to roll back to 10.11.1 for it to be functional again, none of the tips and tricks I have searched for around the web have made any difference; and I've tried a lot of stuff...

Scary thing is that the yet to come 10.11.4 doesn't seem to solve this issue - that is referring to feedback I've seen from beta testers that have encountered the same erratic wifi behavior since 10.11.2.

Maybe we should start listing the hardware hit by this plague. So far most people I have read about are owners of a late 2013 15" Retina Macbook like myself, but most people fail to disclose what computer they're using.

So for those who have not yet found a solution to their unbearable wifi connection, which Mac model are you using?

2013 Retina Macbook Pro

15"? Late 2013?

15" retina MacBook Pro, Late 2013

16GB RAM

2,3 GHz Intel Core i7

You sound awfully certain. Have you tried resetting it or are you just certain it cannot be the problem?  The only reason I say this is because I had exactly the same thoughts for quite a while. I have 2 Macbook Pros (1 2013 retina, 1 2011 non Retina); 2 Macbook Airs (2012 2014); 3 27" iMacs; 3 21" iMacs. Only 1 of the 13" macbook airs exhibited the problem (2014) and I would boot back to the older 10.10 and it would work fine on that MBA. All had the same version of the OS (even the ones that I ran the betas on). So why not the OS? It probably does have something do with the combination of it and the Asus router upgrade--for me.

After reading the tip online to reset the router, I thought what the heck can I lose but a few minutes to set it back up? And it worked.  Do all the updates and the do a factory reset. I just want to make sure that people don't spend of lot of frustrating weeks/months waiting on Apple to fix it, if you can do it yourself in minutes.

Hi brycesteiner,

I'm in the same situation as Bersekone2 and a lot of other people here, I have this issue since the first beta.

Like a lot of us here, I've tried everything:

• Reset all possible parameters on the router, of course
• Playing or resetting DNS
• Resetting PRAM
• Playing or resetting everything in the network parameters
• I forget a lot of things…

The two things that seem to work are downgrading to 10.11.2 or keeping the wifi to Wifi-g norm, not n norm.

So yes, Bersekone2 might sound awfully certain, but it's because he's tried everything like all of us. Since December we're trying to figure out how to properly use the wifi on our $2000+ MacBooks, and despite all of that, we have no solution from Apple, not even an acknowledgment of the problem.

To acknowledge a problem would be to admit you're just like everybody else - the air or superiority would no longer be valid.

I still don't see how it can be a router problem when the same hardware installed with Windows 8.1, or 10 has no issues.

What are Apple doing that's so different to everybody else?

I don't think anyone here is saying its a router problem, our suggestion is a workaround to an issue getting a workable connection over WiFi on some apple PCs

Bersekone2  suggestion to list model info here is a good one

I am experiencing the same issue. Intermittent wifi connection followed by kernel panics and complete cpu and memory usage by the wifi processes. 

Attempted all remedies in the previous posts. For now I go through my monitors lightning cable connection to my computer.

Running 10.11.3 on a Macbook Pro Retina 13-inch Late 2013.  It most certainly is not a router issue as it fails to connect on a plethora of settings.  I hope a fix is release soon as many of you know we don't have ethernet ports on these. So unless you want to tote your display around..... You are screwed.  This has been a continuous problem on el capitan.

NUMBER 2 - DELETE THE WIFI CONNECTION ALTOGETHER AND CREATE A NEW ONE. IT WORKED. THANKS!!

The only thing I haven't been able to try so far (and yes I have restored my all stuff to factory settings many times) is to configure my router to another wifi norm. Unfortunately, I do not have that option on the hardware I use at home, plus I do not have admin access to any other network I use.

Some members of this thread have insisted on the fact that the rest of their electronically connected equipment works flawlessly on their personal networks alongside their problematic Mac(s). My iPhone has never encountered any wifi problem whatsoever anywhere, but one of my Macs is unusable in most cases anywhere...

My point being: I do not walk around all day wondering about the next router's firmware or norm, I simply use my laptop.

This could very well be an OSX wifi driver problem that showed its teeth with 10.11.2, many late 2013 Retina Macbook Pro users seem to be in this turmoil. Different wifi complications exist, we might just not all face the same one, let's try to pin-point things down.

Yes, it seems the issue is linked to Late 2013 MacBooks. As stated above I do not have admin access to work routers or other routers to change the settings to a different standard.

Of course I have deleted the wifi protocol and reinstalled, as well as all the other tips and tricks such as changing IP6 to local link only and the MTS.  However, it seems to be a driver error.  If you stop the kernel panic on system activity it will end the problem but also end your wifi. 

I have bug reported to no avail. But, going on several months now with having intermittent wifi and using my desktop monitor as a channel to the ethernet is getting a bit ridiculous.

Ridiculous indeed!

10.11.4 is out. Has it fixed the problem for anyone?

Problem's still there on my end...
