Problem started after installing El Capitan on my macbook 2015 retina. My 2013 Macbook Pro 13 works fine after the upgrade. The problem may be associated with using e-mail app. If I do not use the e-mail app (and use webbased gmail) then I do not experience the resume problem (yet)... e-mail could be a red herring...
Got a tip for us?

Why, oh why hasn't El Capitan fixed Mac's most infamous WiFi issue after all these years!!!

I have a 2008 MBP with El Capitan on it. Its WiFi works fine. So does my 2012 Mac Mini. I can only surmise there is a setting difference or corrupted file somewhere on these computers since it's too strange that the same models work for some and not for others.
Short answer: I'm reliably informed that for at least one type of access point, outdated firmware is desirable.

I would ask you all who got this problem to go to System Preferences - Energy Saving - UNTICK Wake for network access.
It seems it kind of worked to me (although it's too soon to speak yet). Check it out and post your feedbacks.

In one of my work environments, the network name eduroam is visible.
OS X 10.9.5 on an early 2009 MacBookPro5,2 works fine for me.
OS X 10.10.5 on a 2015 MacBook Pro a few feet away from me finds trouble, almost certainly with the same access point.
For both me and my colleague, the access point is nearby and in sight.
I have not tested OS X 10.11.1 in that environment; El Capitan is not yet supported.
I just had to come on here and say that I FINALLY!!!!!!! (Fingers crossed) seem to have solved my wifi dropout issue, that has been plaguing me for over a year (whenever Yosemite first came out). I've looked at so many forum posts and tried so many things over the last several months, including:
- Fresh Install of Yosemite
- Fresh Install of El Capitan
- Reset SMC
- Tweaked every imaginable setting on my router (Bluetooth settings, channels, WMM, etc. etc.) and several firmware flashes of the router
- Disabled Bluetooth, replaced bluetooth settings, etc.
- New Network settings, etc.
- 'ping' method
- other things I can't even remember
I have two machines - a mid-2011 iMac (running 10.11.1) and a first-gen retina MBP (running 10.10.latest). I have been so frustrated about this issue for so long. I never had constant, severe dropouts like some users did, but basically it seemed that often when I was doing something that lightly stressed my network connection was when it would drop out. The randomness of it was partly why it was so frustrating - I could transfer a huge file across the network for an hour and it would be fine, but then a minute later, trying to load a movie trailer in Safari would kill it and I would have to turn my wireless off then back on to get back on the network. On an average day I would have three to five dropouts, but they also tended to cluster - like four within the same ten minutes. Life like this has sucked a$$ and has required real work arounds since a lot of my work depends on reliable network connections.
So what fixed it? Well I should say, what have I done that now I haven't had a single dropout in three days? DD-WRT.
Here's the interesting part - I've been running MULTIPLE versions of Tomato up until this point. And I have been very thorough over the last couple of months in trying every change I could think of inside Tomato to see if it made a difference. Finally the other day I had some time to kill so I decided to see if changing to a different firmware would make a difference. So first I went back to the stock firmware of my router (Linksys E1200v2). Right away had the same issues. Not knowing if I could go straight back to Tomato without flashing DD-WRT first, I went with an old build of DD-WRT (build 21676 for those curious) that was specific to my router, and just out of curiosity decided to stick with it to see how it went. GLORY GLORY HALLELUJAH.
So I know there are other people out there who have had dropout issues while running DD-WRT - so I'm not claiming I know this is THE solution or that its even feasible since a lot of people aren't able/willing to try different router firmware. But here are my few anecdotal thoughts about why it might have made a difference for me-?
- The build of DD-WRT I'm running is from 2013. This got me curious if there is something in new router builds that are part of the problem, but I couldn't find any versions of Tomato that old for my router to test.
- I still like Tomato more than DD-WRT- the number one reason being it was a lot faster. I can't seem to get nearly the transfer rates to my NAS that I was with Tomato. But that got me thinking - could the dropouts have been caused by me pushing the router too hard? Or maybe pushing my iMac's wifi too hard? The dropouts only seemed to affect my computer (other devices kept running fine) but I wonder if there is like a threshold of performance that triggers the dropout. After all, dropouts did only seem to occur when in the middle of a fast/big data request.
- Other interesting note: this build of DD-WRT is able to wake-on-lan my AppleTV successfully, which Tomato was never able to do (although Tomato could WOL my NAS and other devices). Now I can just select AppleTV to Airplay on my phone and it will wake it right up!
Anyway - I'm gonna keep my fingers crossed that it stays stable. And I wanted to post in here to see if this gives anyone more ideas to try, or some hope at the end of what has been a long tunnel for me.

I have the same wireless POS router from my cable company and the same issue. I've read your posts...but did you ever have any additional luck? I've been searching Google for months...with none.
I don't have WiFi issues with El Capitan and I didn't with Yosemite. There's always two sides to a WiFi story, and in the OP's place I would try other routers.
Two iMacs, Android phone, Android tablet, Linux laptop – no problems.
Brand new Macbook Air, 10.11.1 – no wifi on wake.

Oh OSX wifi problems.. First time I ever had them was with a 2008 Macbook and Lion 10.7.0 (was fixed with 10.7.4 or something). They came back up in Mavericks and Yosemite. I've had it happen on a range of hardware and post 10.7 versions of OSX.. there seems to be no reason or rhyme.
I used Yosemite on my late 2012 iMac for a month to play Tomb Raider 2013. If I'm not mistaken, the game requires internet connection all the time. The game ran fine even if played for 3+ hours. I also use both non-Apple wireless mouse and Bluetooth trackpad.
Now I'm using El Cap on my mid 2009 MBP. I binge-watched Twilight Zone for hours, and it never got disconnected.
Strange how some experience wifi issues while others don't...

According to Wifi tab: Airport
According to Ethernet card: Broadcom 57765-B0
iMacs work fine though, Air had problems. After trying various solutions I deleted the Keychain and Network entries, added them again and so far so good. I'm a bit alarmed though that they somehow managed to break within three days from purchase.
On Mac OS 10.11.4 Public Beta, the bug still persists.
I've reported this bug 3 times this year so far.
Anyone else?

It was so annoying that I sold my last MacBook and got an iPad Pro to replace my laptop and iPad Air. Haven't had one wifi drop as of yet, works perfectly. Also no changes on the wifi side of things either. I had previously bought a new AirPort Extreme, reconfigured the wifi 3 times from scratch and even bought my own stand alone modem to replace the Xfinity modem/router which I thought may have been the issue. I took it to the Genius Bar and they tested and said it was fine, of course it wasn't.
[doublepost=1453016494][/doublepost]I have a MBP late 2013 and i have had this bug since birth of my PC. I am constantly turning off my Wifi off and turning it on again to get a signal. So no upgrade has ever changed this issue. If i move 1m either side to where i am sitting i will lose signal. Not quite what i was hoping for a 1k computer. I know everybody does not have this issue but plenty also do....i would not purchase another MBP on the back of this. My kids have basic microsoft laptops and never ever lose signal. I wish i had an answer for you, but I've tried everything so i just have to put up with it.
Why don't you people with this "supposed" problem just change your WiFi router? It seems obvious from everything I've read THAT is where the problem is. I have a Netgear dual Radio router and I have no problem connecting ANYTHING to to it including a Macbook Pro or Mac Mini (both with El Capitan on them) via WiFi or Apple TVs or FireTVs or iPods or anything else. Apple "fixed" the WiFi for the bug it had (i.e. it's the same WiFi driver type it used prior to Yosemite) so if you're still having problems then it's your router or your WiFi is defective on your particular Apple box.
Well I'm not sure about what "people' you are referring to, but I did change my router, from the xfinity router to an "Apple AirPort Extreme" now if it doesn't work with that automatically what would. Furthermore after doing a lot of testing I don't think it's really router related, my other machines like the iMac I have on wifi-never disconnects, 2 iPads and 2 iPhones in the house-never disconnect. I use constant pings and I can see there is no connection, this doesn't only happen on wake, it happens randomly as well, though the other machines are streaming, surfing just fine. I've had a 2013 retina MacBook and a retina MacBook 12" both same issue, the 2013 ran Yosemite and El Capitan and the 12" ran only El Capitan, which I also performed a clean install to see if the problem subsided.

Except when it happens as a result of a software update and to any wifi networks you happen to be connected to.
It happened to be constantly with one of the OSX Lion updates, then resurfaced in Mavericks and I think also in El Capitan at the beginning.
Following on from everybody else comments, i too have two Microsoft laptops in my house, no connection problems, I have and iPhone 6 my wife an iPhone 5, no connection problems, two work iPads, no connection problems, personal iPad air, no connection problem and my wife has an iPad mini, no connection problems....so clearly there is a problem with my MBP. Thanks for your advise but when i spend 1k on a laptop, i expect to connect to the internet where ever i am.
