Some OS X Yosemite Users Plagued With Wi-Fi Connection Issues

I deleted the plist files as suggested and my Yosemite experience does seem to be better. Made it through a long iTunes download last night without any fuss. My Mac does not seem to be back to where it was with Mavericks, but at least it works. One would think the dev community didn't exercise wifi, as widespread as the issues have been reported (tongue-in-cheek).

I also run some Linux machines and it seems in that world we can never get wifi right, either. If I was younger and wanted to change the world, I'd write 'nix and 'nix variant wifi drivers that always worked.

that worked for me too, for about 24 hours
 
Here's another bug I reported that has not been addressed even though I've been a beta tester since day 1 for Yosemite...

MAIL / KEYCHAIN PASSWORD issues.

Unless I reboot periodically MAIL will not remember the CORRECT passwords from the key chain and keep repeatedly asking me for passwords I already know are correct.

Now this problem is complicated by the fact that often its an issue with AOL or Yahoo servers, but REALLY, can no one figure this out and make it work 24/7?

If you're security wise like me, you have different passwords for various email accounts, so this bug is truly maddening to me and worse in Yosemite than in Mavericks. I've even seen this bug in Leopard, but it got better, and like many things with Apple, then got worse again. :(
 
I had wifi problems with Mavericks soon after installing it - would have to disconnect wifi in the preferences (menu bar wasn't enough) - but got it working pretty well after fiddling with some registry files.

After installing Yosemite - things are pretty the same with a surprising caveat.

My computer is shared with my two children who have their own log-in accounts, and, they prefer the Chrome browser. Soon after upgrading, they began to say they hated the upgrade (Yosemite) - why, because it doesn't work on the internet. I'd troubleshoot a bit and noticed that every time I switched to my account - everything was still working - AND - when switching back, everything still worked.

That was, until the kid loaded Chrome!!! If they did, wifi immediately died. I'd then switch to my account, and back, and viola, everything was golden again! Wow! So, we tried an experiment - and found that just by switching to the login window, and retyping in the password for the same account, wifi would be restored.

Weird. So I told my kids to quit using Chrome - Safari is a much better browser, anyway! No problems since.

There's a simple solution... Just plug in your iPhone 5s with an unsupported Apple cable, it will brick your Bluetooth. Then use a plug in mouse/keyboard to use Feedback Assistant which will then brick your WIFI.

REBOOT and RETRY. Resets your WIFI every time. Problem solved. :D

Why are you people complaining? That's normal right along with the 3 minute boot time on a Mac Pro to the wrong display across the room? Just find your damn TV remote! It's ALL YOUR FAULT FOR NOT DOING A CLEAN INSTALL! DUH! LMAO

-- The NEW Tim Cook Apple
 
This existed in Mavericks until 10.9.4 - no idea what Apple are dicking about with; but they need to stop it.
 
Son's 2014 13" Air was so badly plagued with Wifi issues it was crashing 2-3 times a day (all the crash logs showed the same wifi driver as probable cause).

In the end reverted his machine to prev OS and will wait for a couple of patches before I re-attempt.

Other machines in house have no issues - 2013 macbook pro, 2011 27" iMac, 2010 21.5" imac. All run over wifi.

EDIT (His machine also refused to work with handoff... his 5c worked elsewhere and no other phones would work with the air...)... Coincidence? seems possible.

I've just tested this by downloading an app on Steam.
1. Without the Mac being awake I get a very humble download speed of 2MB/s.
2. If I turn the Mac on it quickly drops to about 25KB/s.
3. I close the Mac and it jumps up to its original speed.
4. Rinse and repeat, it's an incredibly strange issue.:confused:

Steam will try very hard to not interfere with your bandwidth. Are you sure the mac is not downloading some updates? Thereby pushing your Steam download aside.

There are USB Ethernet devices. Silly solution, but if it works. In general ethernet connections are faster and more stable.
 
This has only just started to affect me in the last few days, despite downloading Yosemite on the second day it was available. It will take anywhere from 10-15 seconds for a webpage to load, and sometimes it doesn't load at all. I will have to turn my router on and off to connect. At first I thought my wifi was just slow, but I did a speed test and it confirmed that I'm running at at least 47mbps and my Apple TV is streaming HD stuff perfectly, so it has to be something with my connectivity. Very frustrating.

----------

Actually I just went in and turned off handoff and everything improved dramatically. Still slow on some websites (Macrumors especially??) but that must've been my particular issue. Still hoping for a fix soon, though. I have the 2014 rMBP and I would really life for it to run like a speedy, brand new machine again.

I also noticed this problem only after a while. It definitely was not there right from the start of my Yosemite experience. Now it's also affecting my phone calls, when I call from my rMBP using iPhone. The audio is very choppy and almost useless. Web page loading is getting slower by the day.
 
802.1X Networks - Education

Spoken to Apple for three hours, on the phone...All steps inc clean install.
In recovery mode my MBP 2012 won't connect to wifi.
My signal drops when at work but not home - I'm a university lecturer.
Work use 802.1X, same as most in Europe, and it's that which Yosemite has a problem with, and that Apple 'doesn't support'...That's what they said 'we don't support 802.1X networks' after three hours on the phone!!

Seems standard wifi connections are fine, 802.11a/b/...n/...ac etc

No fix works, there is no fix. Just hope Apple realises and updates quickly. If you send an email at just the moment it drops, the email is lost and doesn't seem to come back into recovered mail, draft, outbox or sent folders. It just vanishes, which means I can't really email important emails from this computer. Crazy really.

WPA2 Enterprise (802.1X) should be support by Yosemite. So you are saying that Yosemite will not connect to such a network although the RADIUS servers are working correctly...?

I've no idea what a Radius server is. I can connect to the networks on a variety of other macs, machines, tablets and phones. I can connect using my mac too but it disconnects frequently and reconnects itself after a few seconds - minutes usually.

Apple care told me 'we don't support 802.1X' and to get help from the tech guys at work!

My mac was fine pre-yosemite.

Often after wifi drops, the wifi logo blinks and continues to blink for a long time after wifi has reconnected. The strangest thing is that in Recovery mode, any kind of attempt at wifi connection instantly says 'connection failed'.
 
This is so annoying, when will there be a patch?

New Mac Pro 6 core Yosemite user here.
Since I updated I have troubles staying connected to wifi. Connections just drops occasionally, disabling and reenabling helps sometimes.
We need a patch here! People can't work like this on their macs.

When you say "...Air was so badly plagued.." that means it was not plagued bad enough. Recheck the use of ly, better written would be "...Air was plagued so bad..."

I'm using Apple Airport Extreme and it can also connect to the WiFi without a single issue. Mavericks, Yosemite, or even Leopard, I haven't run into any WiFi issues UNLESS I'm connecting my Mac to something like the WiFi at Akihabara Train Station. The WiFi connection will keep dropping, but since that is a train station's Free WiFi, I'm not surprised if something like that happen.

I guess people who are complaining about WiFi issue should just go and get the Apple Airport Extreme or Apple Time Capsule.

Since Yosemite, I've had problems with network performance for my 2013 iMac. My network gear is a 5th gen extreme and 3 expresses to extend. According to airport utility on my mac, the routers have been continually rebooting but now it looks like I'm realizing it was the iMac loosing connection all along. I couldn't stream to any express the other night and realized it would work fine from my phone.
 
I experienced the problem and it was maddening. I only got if fixed by following the directions posted about purging the pslist...
 
Early 2014 rMBP and 2012 MBA.

The rMBP has all sorts of problems even with the latest Airport Extreme / Airport Express routers (same setup at two different locations).

The rMBP has more problems than the MBA.

Right now I'm on a Verizon mifi (staying with somebody) and it's awful. Today I've been dropped 10 or 12 times. Making a new location and bringing the mifi to the top of the list has helped, but hasn't completely fixed it.

A few days ago I had to use my iPhone 5 as a hot spot for the rMBP and that was an adventure. I got my work done eventually but it was a real chore. Under Mavericks I never had hotspot problems.

On Mavericks, back home (AE) being dropped was a rare event.
