Jan 29, 2015 5:48 AM in response to Dillonphotoby Lysin,★HelpfulHi Dillonphoto,
I had the exact same problem.
Wifi in 10.10.1 was not perfect but it worked.
After the 10.10.2 update it became painfully bad. Dropped packets, pings floating from 100 to 1000's and timeouts, no internet for large amount of times, etc.
I contacted apple support and they said they had no reports of a bug in the last update, and after running numerous tests they suggested I dropped by an apple repair certificated facility to run more tests.
As it turns out, this is a bug with the latest wireless drivers. They may have fixed the WiFI for other but they ruined it for me.
I resolved the issue (temporarily of course) by reverting the wireless driver to the one before the update.
I just hope apple notices the bug and fixes it.

Jan 29, 2015 6:15 AM in response to Dillonphotoby Lysin,★HelpfulIf you have a backup from 10.10.1 browse your backup and go to /System/Library/Extensions and copy the file IO80211Family.kext.
First, shut down wifi.
Next, in your updated system (running 10.10.2) go to the same path and make a backup of the same file. If you click get info on both files you can see that 10.10.1 had the version 7.0 and 10.10.2 has the version 7.1
Now paste and replace the IO80211Family.kext file.
To be sure everything is fine regarding permissions, run Disk Utility and press Repair Permissions.
When finished, reboot.
If you don't have a backup I can try and upload mine, but I'm not sure it will work across different devices.
Please let me know if this helped.

Jan 29, 2015 1:30 PM in response to Lysinby rcmarple,Thank you Lysin. This fixed the issue on my 2014 iMac Retina - never had a wifi problem before 10.10.2 then became virtually unusable. All back to normal now.

Jan 29, 2015 4:35 PM in response to Dillonphotoby Todd Rockey,I have this problem also. Syncing two mac use to take 3 minutes, now 28 minutes. Downloading anything from the web take hours.
Why can't Apple get this right?????? Do we need to wait months for this to get resolved? And these things never come up during beta???

Jan 30, 2015 1:19 PM in response to Lysinby Dillonphoto,Thanks Lysin,
I've finally been able to get around to replace the IO80211Family.kext file as you suggested with a time machine copy from before 10.10.2
After a restart my WiFi speeds are now back to 45 Mbps down and 16 Mbps up - whereas this afternoon, before the change they were 2 Mbps down and 5 Mbps up!
What a stupid situation!!
Thanks again
Dillon

Jan 30, 2015 1:24 PM in response to Dillonphotoby Todd Rockey,Does reverting back to the IO80211Family.kext version 7.0 mean that we will gain back issues with wifi dropping-out and disconnection?

Jan 30, 2015 1:56 PM in response to Todd Rockeyby Dillonphoto,That's a good point - will have to wait and see - but the 10.10.2 update made it TOTALLY unusable...

Jan 31, 2015 3:37 AM in response to Lysinby Dillonphoto,What machine did you have your issue on Lysin?
I've just done the 10.10.2 update on my old (2010) MacBook Air (2.13 Core 2 Duo) and I didn't get the same issue as we've had?
I wonder if it is model based therefore?

Mine is a Macbook Pro mid-2014, 2,8GHz . This must be something with the wireless drivers for newer cards, because not everyone is having the same issue.
I'm happy this worked for you guys. It's not a solution but at least we get to use our mac's.
PS: I also reiceved an email from apple asking to help them narrow down the origin of the issues. Logs sent and now waiting for a fix
Cheers
