This is not the most "infamous WIFI bug." The most infamous WIFI bug, according to most historians, is buggerito wifirenzus, more commonly known as "Buggy the Kid," the baby-faced cockroach who terrorized the still-nascent wireless internet in the early 1990's, roaming the southwestern U.S., rustling bandwidth as he travelled from small town to small town with the ethercops always two steps behind.

It's a brand new Mac, WiFi issue out of the box. Same WiFi issue on my MBP 2015, 2014, 2012, MBA 2013, 3 different houses, 7 different routers.
Incredible. Never had an issue like that! Have you submitted a bug report to Apple at least once?
 
Are you talking about Time Machine Backup? If so, I would love to know how you are getting that performance. I can see that drag and dropping files to my NAS, but never with Time Machine.

I don't want to go off topic so let's not get into a big discussion about this. But it's quite a coincidence you mention it because just today I installed the latest Synology DSM 6.1 beta. It supports Time Machine over SMB (previous versions only AFP) and I have witnessed a performance increase now I'm using it.

If your NAS supports TM over SMB, use it.

I'm still omniscience's the 6.0 branch. Just out of curiosity, do you have to configure DSM to use SMB, and if so, where is that done? (on 6.0, time machine is under "mac file service," so I'm just curious how they handle configuration).

It's really simple, there are even notes in the web interface about it. Under 6.1 You turn off the Mac file service (now renamed AFP) and you turn on Enable Bonjour Time Machine broadcast via SMB.

Thanks. Not using a Synology, Netgear ReadyNAS Pro. Maybe it is time to change NASes!
 
Could this by an IPv4 vs IPv6 negotiation issue? I've had a similar problem with WiFi dropping ever since I upgraded from Yosemite. Since then I briefly loose a wifi connection shortly after waking up from sleep. The oddest oddity in my circumstances is that under network preferences my displayed IP address shifts to what looks like IPv6 format while internet access is lost before returning to the classic IPv4 format when the connection is restored.
 
I want to say that it does have something to do with IPv6. When I had the problem with the iMac back during Lion was the last time I really looked into it.
When Yosemite came out and had the much bigger wifi issue, I waited on purpose till 10.0.1 came out. Apple patched it again not too long after to fix it again, but I wasn't affected by it.

The issue with Sierra isn't nearly as bad, but it is there. And BTW people, I'm not at home right now.. totally different router setup, and it happened again. (I wasn't going to bother checking the forums while i was here, but the wifi dropped...)
 
Bug: WiFi fails to auto-reconnect after long idling

I really thought this bug would become history with the new MacBook Pros. Not so fast. Not the latest software, not even the latest and greatest hardware was able to permanently fix this damn bug. I can't believe after all these years, it's still an issue. I went though so many Macs, so many OS's, and it's there every damn time.

[crying]
I feel your pain
I work in a small business
They use an Pancake style AirPort Extreme

The Ssid for the 2.4 and 5 ghz radios are different
The Ssid is hidden
They use MAC authentication

Just about everything that Apple says don't do.

Doing a network scan (inet) there are 40 + DHCP address active in the scan.

There is a bunch of legacy 802.11 b/g junk on the network from webcams by the doors,
Old hp printers, scanners, fax machines.

For pcs there are Windows desktops and laptops running Windows 7 and 10 and a few MacBooks and an apple air.

I use my own 2012 MacBook Pro retina. An iPhone 7 and and Apple Watch from my cubicle.

I'm not the system admin and I don't get to tell them how to run their business, just a consultant.

The single biggest help for me and connection issues was
After making a connection Forgetting The Network
Shutting down the machine, complete power off
Then when reestablishing a Network 2.4 GHz connection
PICKING WPA2 Personal in the Security dialog
Box before putting in the network password.

I use 2.4 GHz because my Apple Watch does not have a 5GHz radio and everything plays nicely.

As A test After giving the IT guy the MAC address I just added an iPad with no issues.

I can understand your frustration as I know this issue. However I have learned how to tackle it, hopefully this will help you as well.

Basically it depends on a combination of aluminum enclosure, quality of the wifi chip, router and... most important: quantity of wifi signals around you.

What helped me to solve this is to change the channel on the router and on the Mac.
It is annoying for two reasons:
- you have to try all of them one by one
- you have to set the channel to manual, therefore it may not work on your macbook when you leave your home (you need to put it back in automatic mode)

I am now used to do this everytime I move and it solves my problem as I have a mac mini and my girlfriend has a macbook which she tipically uses just at home. Hopefully it does it for you as well.
