Jan 29, 2015 11:59 PM in response to Illcomm66by jndupuis1,I failed to mention. I did yet another clean install on my External HD. Installed 10.10.1, configured, installed purchases and immediately installed 10.10.2 update.

Jan 30, 2015 12:42 AM in response to hexdiyby Akos G. Garai,Hi hexdiy,
Had a look at the suggested sites and found something intriguing in the process (direct link to a post):
Re: New Macbook Air - wifi connectivity problems
Very similar issue (BT killing Wi-Fi downstream) dated May 25th, 2014 with the exact same card (or so it seems based on the HW IDs) on Maverics (now that's bad news for me).
As for the tech details of my early 2014 MBA:
Card Type: AirPort Extreme (0x14E4, 0x117)
Firmware Version: Broadcom BCM43xx 1.0 (7.15.159.13.12)
I'd been contacted by Apple Wireless support to provide some details (I'm out of town now, but I'll do that next week when I'm back in the office) so they do care about resolving this.
On the other hand judging from the whole lot I believe the Wi-Fi / BT problem might actually be related to the Broadcom chipset itself.
I'll send the reports to Apple and then most probably do a complete re-install of Yosemite to 10.10.1 and then update to 10.10.2.
If that does not help than I'll try to get the Apple Service Centre to replace the Wi-Fi card...
Update:
Strange...just looked at Hardware / Bluetooth under System Information:
Apple Bluetooth Software Version: 4.3.2f6 15235
Hardware, Features, and Settings:
Address: 9C-F3-87-D0-C9-81
Bluetooth Low Energy Supported: Yes
Handoff Supported: Yes
Instant Hotspot Supported: Yes
Manufacturer: Broadcom
Transport: USB
Chipset: Unknown (ffff)
Firmware Version: v99 c8867
Bluetooth Power: Off

Auto Seek Pointing: Off
Remote wake: On

Product ID: 0x828F
HCI Version: 0x6
HCI Revision: 0x22A3

I'm not sure, but this is the first 10 minute period I haven't been knocked off since upgrading last night. Good luck!"
- Tried this, no change.
just as a sidenote:
i never had any wifi problems since years, i am using 2 macs (imac 27" late 2013 / mbair late 2013) and 1 iphone 6 plus and 1 ipad air.
i was on 10.10.1.
yesterday i updated to 10.10.2 and i had my first wifi problem during the whole day. it kept disconnecting without any reason every 5 minutes.
tried this (above), and after reboot wifi is working stable until now (10minutes). will report back..
thanks!

Jan 30, 2015 1:43 AM in response to jndupuis1by AndreasSt,I also currently don't have WiFi issues with my MacMini 2012 and OS X 10.10.2 (clean install from scratch).
My best-practice tipp is to use then 5GHz network for all Macs, especially when using Bluetooth devices. However, OS X does often fall back to the 2.4GHz network automatically. To stop this, you'll have to assign both networks different SSIDs. Then you'll have to make sure that the 2.4GHz network remains unacessible for OS X (hence remove it from the known network list). Note that the AirPort Utility will add it back to the known network list, when accessing the AirPort base station. All iOS devices should be associated to the 2.4GHz network for best performance.

Jan 30, 2015 2:21 AM in response to tomstephens89by Babucifer,Hei,
Just installed the 10.10.2 update on my mid 2014 macbook pro. Had no problems with 10.10.1 and after this update (about an hour ago) no wireless network works. Tried a couple of them in the building where i work, with different hardware configurations, and still nothing.
This computer had a fresh installations, out of the box, 1 month ago when i bought it new.
I tried also the 10.10.2 Combo update but still nothing.
Only way working is when i setup a mobile hotspot with my samsung galaxy note 2...but this is not a solution.
Pls help

Jan 30, 2015 2:21 AM in response to Babuciferby peppermint,this worked for me !

Jan 30, 2015 2:54 AM in response to LadyPacby bcanuel,Ditto from me and very sorry to hear resolution of this issue is still not available. I had actually tried to load Yosemite when it was first available and bricked my late 2009 MBP! (That might have been a user error but I learned later that Yosemite would not work with 3rd-party SSD's (something to do with KEXT signing). That alone means I'll never load Yosemite.) Restored Mavericks and things have run smoothly ever since...as usual. Looks like I'll be on Mavericks for a very long time.

are you sure?
i installed 10.10 on an external SSD (thunderbolt), brand: Intel SSD and it worked

Jan 30, 2015 3:01 AM in response to tomstephens89by Theral Sadurns,With the official 10.10.2 version the WiFi issues persist. Funny thing though:
the fifth public/dev beta build 14C106a had solved the issues. The release version build 14C109 reintroduced them.

Jan 30, 2015 3:58 AM in response to AndreasStby jndupuis1,My practice in Mavericks as I have carried through to 10.10.2 is to make sure that I change my .local name in sharing. System Prefs>Sharing>Edit. Then make that name different from the Computer Name. I then use that name as my NetBios name System Prefs>Network>Advanced under WINS Tab use the .local name as your NetBios Name. Then I change WorkGroup to HomeGroup in both Wi-Fi and Ethernet. I have not modified or changed anything else. My Router is a Linksys N750 (EA3500). I have manually configured. No Cisco Connect software installed. Media Prioritization turned ON. I dragged my Mac Mini icon to Top of list in High Priority. This helps for smooth media streaming. My wife's iPhone and Macbook Pro are connected to 5 GHz and in the High priority list of the router as well.
This morning Yosemite 10.10.2 is running very well on my Mac Mini (late 2012). Amazing. I have opened Mail clicked on "go to discussion" Safari opened and I'm typing this with no Wi-Fi issue. Still monitoring.

Jan 30, 2015 4:41 AM in response to peppermintby jndupuis1,I have my 10.10.2 installed on a Thunderbolt External as well. My Mavericks and Boot Camp:Windows 7 Pro are residing quietly on the internal HD. I have Wireless Diagnostics running to detect drops and to send logs to Apple Engineering as they occur. My above outlined settings (my post to AndreasSt) is all I have done along with proper router configuration. I will continue to monitor on my day off today. As time and days go by I want to see drops as they occur as reported in this thread. I would like to see this put to bed and behind us. 10.10.2 is the closest I've seen to stable since Yosemite's release. Hope it worked for a lot of you. Again I took the plunge and performed a "clean" install on my external HD as I am not ready to replace my Mavericks just yet.

Jan 30, 2015 4:44 AM in response to jndupuis1by jndupuis1,I do not have Keychain active. I did not like it in Mavericks. So, I do not use it.

Jan 30, 2015 5:17 AM in response to peppermintby Akos G. Garai,I don't know if the below helps, but it's worth a try. It's basically for re-initializing the interfaces...
(I could not have BT and Wi-Fi together as BT killed off the downstream, but now it actually looks like it got fixed for the last 4 hours)
This needs a few restarts and some fiddling with settings (in case of iMacs I'd say suit disconnect from the mains):
1. Under "Network Preferences" with the "-" remove ALL PRESENT interfaces (Wi-Fi, Bluetooth PAN, etc...)...Press Apply
2. Shut down the Macbook and disconnect from the charger
3. Leave it for at least 3 minutes (I'd left it alone for 5 actually)
4. Start up and go again into "Network Preferences" (Don't be surprised by the Wi-Fi icon having a big "x" in the middle)
5. Click on "Locations" and then "Edit locations"
6. With the "+" add a new location (I'd called mine "General", just make sure that it's different from any previous (I'd used Automatic and Internet beforehand)
(Note: Wi-Fi will come up, but will still show the "x", no worries, don't do anything else)
7. While still in there with the "-" sign remove the one you used to have and highlight the one which You'd just added.
8. Press on "Done" and then "Apply"
9. Click on the "cogwheel" and then "Set Service Order"
10. Drag Wi-Fi to the top of the list (or at least above Bluetooth)
11. Click on "OK" and then "Apply"
12. Shut down the Macbook and leave it unplugged from the power supply for at least 3 minutes (I'd left mine like that for 5 minutes).
13. Start up...and hopefully enjoy BT and Wi-Fi working together...
14. Let the community know if this actually helped or not...With me now it seems like DL/UL is actually more stable having BT on than without it...
Cheers...
(It might be also a good idea to re-boot your Router and/or Access Point while you're counting the seconds during the second shutdown...)

Jan 30, 2015 7:01 AM in response to tomstephens89by airbrush30,I was having internet connection issues on my Macbook Pro as soon as I upgraded to Yosemite. I could get on the web using Crome, but if I tried Safari, App Store, or iTunes, I was getting no where. Tried troubleshooting it in different ways according to several suggestions in the support pages/web and final decided to get in contact with Apple.
We went through three different tests…this is what worked for me (Test#3). Hope it helps someone.
TEST#1
first create a test account
Open System Preferences by clicking the in the upper left and selecting it from the drop down menu.
Choose "Users & Groups" under the System list, then Click the Lock to unlock then to make changes. You will be prompted for your Computer password.
Select the + directly above the Lock to add an account. The format should be as follows:
New Account: Administrator
Full Name: Test User
Account name: testuser
(Use separate Password): Test
Verify: Test
Password hint: Test
I would like for you to use Safari to see if you are having the same issue.
Alright you may delete the test user account.
TEST#2
Next we will perform a pram reset: What the reset does is reset the settings controlling your speaker volume, screen resolution, startup disk selections, time zone information, Keyboard and a few other settings. (No data would be lost.)
Here is how to reset the PRAM:
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Here are the remaining steps:
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
You may let me know when you hear the startup sound more than once please.
While holding down the keys after pressing the power button to turn on, you may see a grey screen, but it goes off really fast.
TEST#3
Our next step would be to use the Disk Utility application to check the hard drive for any errors.
Here are the first set of steps:
1. Shut down the system.
2. Hit the power button to turn on the computer, immediately hold down both the left command key and the R key.
1. Keep those two keys held down until you see a bar loading to the bottom of the screen and then release the keys.
2. Select “English” in the language menu then click on continue or next.
Here are the remaining steps.
1. When the menu comes up Select “Disk Utility” from the menu.
Great: Here are the next steps: 1. On the left hand side select “MacIntosh HD”
2. On the bottom right hand side, click on “Verify Disk”(this may take a few minutes)
3. If the results shows “The disk seems to be okay” in green, then quit disk Utility.
4. If the results shows “The disk seems to have errors” in red, then click on the “repair” key on the bottom left.
Okay let’s verify it again
Me:it went through with no errors
Awesome, so what we can do is restart the system then check to see if you are still having the same issue. If you are the next step would be to reinstall the OS X which would place a fresh copy of the OS X on the macbook pro along with your data.
Quit Disk Utility
Then you restart.
Test Safari, App store, iTunes store
