I use ethernet with Wi-Fi turned off at work. I brought my laptop home after updating to 10.10.1 and turned Wi-Fi on.... internet didn't connect automatically, had to click my network for it to join.
 
Slightly unrelated: I downloaded the update but haven't restarted yet and now I don't want to. Is there a way to get rid of the update now?
 
MY rMBP late 2013 worked fine before the update and fine after the update.

I have a apple time capsule if that makes any difference.
 
Didn't have problems before the upgrade; sure DID after

I don't think I had any Wi-Fi issues, but I ran the upgrade simply because I install all upgrades. After that, on my iMac, my Wi-Fi couldn't even get an IP address, and my Ethernet connection could get an IP address but even though it did, it could not provide Internet connectivity.

I was forced to roll back to 10.10 via an online restore of the OS.

10.10.1 was nothing less than a disaster for my networking.
 
came here to say wifi still disconnects after waking from sleep

It used to disconnect twice before sticking, this time it did it 3 times as I was trying to load the forums (when waking you get about 30 seconds of wifi before it disconnects and you have to select your router again).

so no they didnt fix anything
 
Cause I'm not upgrading unless it has. :D

Mine works just fine. Never had an issue from day one with 10.10 nor 10.10.1. I have the Apple Airport Extreme newest version. I did a clean install and installed fresh my programs not from a back up. I changed my DNS server to a faster one, and changed my Wireless channel to a faster one as well. Unknown why others are having issues.
 
Has anyone with wifi issues still after the update removed all the wifi network connections and re-established them to see if that helps?
 
My wifi had been awful after the initial Yosemite upgrade. I have a developer account and I downloaded the beta update last week but I read all the warnings and did not attempt an install. Somehow over the last week my wifi began working normally. I did the upgrade this morning, still working ok.
 
Decided to just do it because this laptop is ruined now anyway, and immediately upon starting up it dropped wifi again. So there's that.
 
It took me 3 seconds to connect to the university wifi network today, instead of 3 minutes like it's taken since I upgraded to Yosemite. So probably sort of?

Edit: An hour in, and my connection hasn't dropped. It was dropping out every 10 minutes before.

Like I said in the other thread, it is hard for them to fix a bug that I never had.

I went from Lion straight up to Yosemite on my mid-2011 MBA (clean install), and have had no problems at all with WiFi.

If indeed a bug, it is hit-or-miss with a number of models, as I've seen people complain about it, and I've seen people say they haven't had a problem. I'm in the boat of the latter. I'm making the jump to 10.10.1 now, and I'll report back if I have or don't have WiFi.

i still have the Wifi problem.... When mba goes to sleep then wake it up the wifi indicator says i got full bars, but no internet...
 
mine's finally working

Before the update it was playing peek a boo. It would connect disappear connect disappear...seems like you were trying to catch it and couldn't only fix was hard reboot...thankfully now since the update its working Whew!!!!!!!
 
I had a bunch of WiFi problems on Mavericks (both in the office and with my home Time Capsule). Yosemite (starting with developer previews) fixed it all :D
 
Still broken on rMBP late 2013 with external GPU - as it was with 10.10.0.

The rMBP is connected to an Airport Extreme, I measure throughput speed to another MBP connected via LAN cable to the Airport Extreme. WiFi speed is fine when I boot from an external clone of my last Mavericks installation.

It is still under warranty / Apple Care so I am toying with the idea to just bring it in the shop and tell them to fix it for me.
 
Back from running the update, and now am on 10.10.1.

WiFi still works for me. MacBookAir4,2.

So whatever ails WiFi for some isn't across the board.
