The long term solution if you can see more than a few neighbors' Routers is to upgrade to a dual-Band Router, and use the 5GHz band. It adds several more channels, and they are wider.
This doesn't work. For me anyway. I had the issue on my router which is dual band (2.4 & 5Ghz networks). Scanning my local area there are no other 5Gz networks nearby. I've left the channel on auto and tried manually selecting several channels. The problem persists.
I've got the beta build of OSX Yosemite on a separate partition and when I'm using that, I don't appear to be having the problem. Hoping they've finally fixed the issue with the latest release of OSX.

Jul 26, 2014 8:22 AM in response to rhironsby VidyaRajaram,Try doing a fresh install using an USB. I downloaded Mavericks [10.9.4] from AppStore yesterday and did a fresh install. I was having all the issues listed in this whole thread previously but after the clean install, I don't have any connection dropouts. I am having rMBP Late 2013 13".
Create the USB using the createinstallmedia option as specified in various sites.

Jul 29, 2014 9:37 AM in response to rhironsby monty88haynes,(Sorry my screenshot is so GIANT!!! Don't know how to make it smaller.) I don't want to jinx myself but I upgraded to a dual band router last week and it has been connecting ALL BY ITSELF without me turning wifi off and turning it back on again. In other words it has been working like a normal computer should. When I go out into the garden it still connects to 802.11n because it's out of range of ac. And to tempt fate I hooked up my Bose Soundlink Mini which disrupted everything the first time and everything has been working smoothly for two days now. Now I have Bose and mouse hooked up via bluetooth. Hope I don't have to post in a few days time that everything has gone wonky again. Good luck everyone and the release of Yosemite can't come soon enough.

Level 9 (61,180 points)
DesktopsYour connection shown here is on Channel 36, (anything above 14 is in the 5GHz band. Channels there are wider, and there is far less interference. You have a really strong signal at -48, and you transmit speed is a phenomenal 1300. You have left all your neighbors and all your Bluetooth devices behind in the 2.4GHz band.
The new Router may also have more and better antennas in the 2.4GHx band, so that may work a little better when you are out of range of 802.11ac.

Aug 1, 2014 10:50 AM in response to Grant Bennet-Alderby monty88haynes,Thanks for the analysis Grant. The transmit rate is not always 1300 but it is usually 878 to 702 when I am sitting about 2 meters away from the router. I am connecting automatically for the past week so I think it is all clear. Thanks again.

It just starts to fail!!! to solve i need to turn wifi off&on
The wifi icon show that the connection is ok and also i know it is connected to the router. This doesn't happen with my iPhones and windows machine in the same network.
The BT is off and this happens 3 or 4 times per hour. It is quite annoying.
My computer is a macbook pro 13" retina, 8GB, 2.4Ghz intel core i5

Aug 20, 2014 10:15 AM in response to ShaneD90by rhirons,I've found a solution to the issue. For me anyway Your mileage may vary. I'm sorry if this has been posted before as a potential fix. I'm not about to check 50 pages of posts to find out
Solution
Delete your bluetooth plist file and reboot. This worked for me on the latest version of Mavericks and the Yosemite beta preview.
- Go to your Mac's Finder.
- Click on the File menu and select New Finder Window
- Click on your Mac's icon in the Devices list in the sidebar
- Open Macintosh HD (or whatever your Mac's hard drive may be named)
- Open Library
- Open Preferences
- Find the file called "com.apple.Bluetooth.plist"
- Move it to your desktop. It should copy there.
- Remove it from the Preferences folder by dragging it into the Trash. The Mac will tell you that Finder wants to make changes. Type your password to allow this.
- Restart your Mac.

Hope this works for you too.

Sep 8, 2014 12:38 AM in response to ShaneD90by Surjective,Hello everybody. I recently bought a macbook pro retina 15" late 2013.
I have some wifi issues. For exemple, when I switch on my macbook, all my devices (macbook pro included) disconnect from wifi. I need to wait 1 or 2 minutes to reconnect.
I have some connection drops. It's not a big problem now but I'm afraid it get worse.
Any fix ? You think it's a hardware or software problem ?
-
Sep 8, 2014 2:12 PM in response to ShaneD90by Surjective,Ok, things are getting worse.
My macbook refused to connect when I turned it back from sleep.
I'm afraid. Is it a hardware problem ?

Sep 10, 2014 2:44 PM in response to ShaneD90by jd78,Hi I've tried to read though most of this massive thread, and can see there are lots of issues going on.
I have not see one exactly like I am having (maybe jonnycache?), so I will describe it to see if anyone has successfully solved it.
I have my macbook connected by wifi to a NAS via a TP Link ac router. The NAS is gigabit wired to the router. When all is working well I get transfer speeds between mac and Nas of 40-50MB/s and am very happy with this.
Sometimes though the transfer speeds drop to 2-3MB/s. It seems random when this occurs - maybe a couple of times a week. I thought it was related to the macbook sleeping rather than being shut down, but can't reliably repeat this. Sometime it can sleep and wake up fine, sometimes it can be fully shut down and then be slow after starting up.
The wifi always connects quickly and almost never seems to fully drop out, so I'm not seeing some of the issues mentioned in this thread, just a massive speed reduction.
The only reliable way to restore the speed is to reboot the router. A couple of times I have restored the fast speed by deleting the wifi connection and restoring it (entering the password again), but this doesn't usually work.
I have a support case with TP Link and they have offered to replace the router, but having read this thread I have my doubts over whether this will help, and strongly suspect the mac to be the issue. Unfortunately I don't have any other AC clients with which to test the speed.
I just can't understand why the router reboot always restores the speed - what is changing? Rebooting the mac doesn't fix it.
Is it worth opening a support case with Apple? Should I try the router exchange? Any other ideas?
The 2.4Ghz band seems solid by the way, no major speed variations. But obviously with this I can't get AC speeds.
Here is my screenshot from a time when it was slow in case it helps (the stats are pretty much the same whether the speed is fast or slow):
Many Thanks!

Oct 6, 2014 3:57 AM in response to ShaneD90by FilipVesely,Hello everyone!
I want to share my experience about this issue.
I had the same issue with my Macbook Pro Retina 13 Late 2013 bought in March 2014.
I had problems when using Magic Mouse and dropping wifi connection. However it happened scarcerly also with bluetooth off. I measured it with a router pinging and I could observer "Request timeouts" in random chunks and erratic pings.
I could conclude that this happens mainly with 802.11g/n 2.4G networks, when you are futher away from the router, although the network strength indicates full signal. The G network performs worse than N network.
The issue fits exactly to the same one with MB Air: http://www.midwesternmac.com/blogs/jeff-geerling/2013-macbook-air-wifi-problems
I tried everything what I could find about the issue, nothing worked at all.
I had it serviced in Authorized Service Centers twice here in Czech Republic.
First time, they reported faulty Airport Card and replaced it. It did not change.
Second time (a different one) they could not reproduce the issue. In my opinion, they did not really try. They provided me a testing log with ping, which exposed "Request timeouts", but this was nothing for them to care about.
Then I got in touch with Apple Customer Center and demanded to replace my MacBook. After two month of negotiations, this actually happened.
I got a brand new Macbook Pro Retina 13 Mid 2014. It did not change at all.
This means to me that this is considered as a "normal system behavior" and it does not seem to be considered at Apple side as an issue.
I don't really see any solution to this now.
Hope you wi-fi and bluetooth works fine!
Cheers,
Filip

Oct 12, 2014 10:36 AM in response to FilipVeselyby phoneuser,This somehow tells you how the quality control in both SW and HW has gone down since Steve Jobs has passed away. I have this laptop for 1/2 year and this problem has not been fixed with different tries. also, SMB authentication bug is still there. IOS8 is full of bugs. The share my location is confusing since it is everywhere in the settings, and when you are in the middle of something the portrait and landscape mode always mess up the title bar....
Those things could only happened in Windows and Android.
I am deeply worried if apple is going to be as bad as the others in a few years.... Tim Cook needs to be tough on his QA team!!!

Oct 16, 2014 8:20 PM in response to ShaneD90by chotty1,I can confirm this issue is 100% FIXED (MacBook Pro 13" late 2013) with today's release of OS X Yosemite 10.10.
