Slow internet connection after update to OS X Yosemite

OK, so I am back.

My fix worked for 1 full day. Upon restarting the machine, I am relegated once again to 1980's dial-up speeds and cannot function in the workplace on this machine. I have pulled out my 'ol trustee windows machine and will be using that until I get a fix.

I must have just gotten a "Bad Apple" with this one. Gee, I sure hope that name doesn't stick.

"The Bad Apple Update" or the new PC commercials. "You *could* buy a mac, I just hope you don't get a BAD APPLE"...... Marketers could really have some fun with this one!

for download 8 mega of document, it took me 6 minutes.

is this an apple support forum or is just a diner were we talk about weather?

So they did an "update" but it didn't change a **** thing. Wifi barely works if at all and ethernet connection works fine. This is really bad of Apple considering that this update was supposed to fix this!!!

Turn off BLUETOOTH DUN and BLUETOOTH PAN, they are not used for bluetooth mouse or iOS bluetooth.

I am having the same problem and it is extremely annoying!! I hardly use my macbook because of it so please apple do something and try to be useful!

Finally I did a clean install on my macbook pro.

A week ago I backed up my data with Super Dooper and I only restored some necessary data. I did not use time machine, because a restore with time machine would give me also the junk data.

The internet speed increased more than 100%.

I am having the same problem but I now know the cause: simply Yosemite. Ran a ping test using a very old Windows laptop and Internet Explorer using a wireless connection and got Ping at 44MS and Jitter at 1. Ran the same test using a MacPro and Safari using both a wired and wireless connection and got Ping at 67 MS and Jitter at 4. I then tested Firefox on the same MacPro with no better results.

Go here to run test: http://www.pingtest.net/ Please post results. Good results are around 40 and 1.

The difference here is significant and is indicative that something in Yosemite is causing poor Internet throughput. This is not a WiFi problem nor a browser problem as can be seen above. This may be a network interfacing problem within the OS. BTW: I have the same problem on an iMac and an Air. All three boxes received a completely clean install of the OS.

Hope Apple is on this and will provide a fix.

I have to macs: an older MBP (MacBook Pro) 2008 and an MBA (Macbook Air) 2012. My MBP has Mavericks installed, and my MBA has Yosemite. I ran speed tests several times in both on different days (www.speedtest.com) and consistently received on avg. these results.

MBP with Mavericks = 22.0 Mbps download speed, 2.2 Mbps upload speed.

MBA with Yosemite = 3.0 Mbps download speed, 2.2 Mbps upload speed.

Clearly this is either a Yosemite issue or an issue with my MBA wifi card. But given that many people are having the same issued, I would have to point to Yosemite as the culprit.

Does anyone know how I can downgrade to Mavericks ? or whether there is a fix? I tried reducing transparency, turning off dose encryption but no luck.

I find this article that suggest a temporary fix for Yosemite and other ios devices

Here the part about Yosemite:

Yosemite WiFi Issues Fix

This issue with D2D/AWDL is the same root cause of the severe WiFi performance degradation affecting users on Yosemite (continues on 10.10.1). Although AirDrop was introduced in OSX Lion and used AWDL, with the release of iOS 8, perhaps there’s more sharing or just some bad new code. AirDrop and AWDL have been active since iOS 7, yet the issue seems to have suddenly appeared in iOS 8.

@rpetrich mentioned AirDrop used to be two incompatible, but identically named protocols until Yosemite/iOS 8. Perhaps this and the changes for continuity introduced bugs in this area.

Turning off AWDL

Perhaps not surprising for Apple users, you actually can’t easily (see below) turn off AWDL/AirDrop in Yosemite. You can remove it from the left side of Finder, but that doesn’t fix the issue. Apple? User choice?

Either way, you can fix your Yosemite WiFi issues, at the cost of disabling AWDL and AirDrop, by typing the following command at the OSX terminal:

sudo ifconfig awdl0 down

And vice versa to restore AirDrop and AWDL (and the WiFi issues)

sudo ifconfig awdl0 up

For clarification: that’s “a w d (lowercase L) (number zero)”

Update: Older Mac’s/MacBooks may not have this interface on Yosemite due to hardware incompatibilities. Based onhttp://recode.net/2014/10/16/os-x-yosemite-arrives-what-does-it-mean-for-older-m acs/, looks like they don’t have full AirDrop and probably don’t support AWDL.

Removing the system passwords for my bluetooth iphone connection (from keychain) did the trick for me too. Insane,

After removing Airdrop linking via Terminal, my connection got better for a while but now just as bad as ever. Connects quickly to wifi and ISP but then takes up to 10 minutes to find internet. Then connection is unstable. Roll on 10.10.2, where there is a faint hope that it might cure the problem. Devices not using Yosemite (older Macs using legacy operating systems and iOS devices) connect immediately via the same wifi network, so definitely a Yosemite problem.

I am fairly sure I have now diagnosed the problem but there is little I can do about it. My RMBP's internet is slow to connect whenever I am in the vicinity of either my Mac Mini or iMac and Bluetooth is active on either of those. As the Mac Mini uses Bluetooth for both its Keyboard and Trackpad and my iMac for its Magic Mouse, there is little I can do about this. It staggers me that Apple did not pick this up and cure it at the beta stage.

It helped for a short while, now speeds are back to being ridiculously slow. 0.2 mbps initially, then bursting up to 9 mbps. I should be getting 40+ mbps. Arg!

Well, I've wasted hours trying everything advised. It works, but only briefly. This suggests we are treating the symptoms, not the cause. I'm so tired of doing the fixes, achieving fast internet ... and then it just slows down again.

Yosemite must be fundamentally flawed to cause this. Hard to believe Apple could have released this obvious bug. This and the IOS 8 problems have certainly taught me a lesson: NEVER, EVER UPDATE IN THE FIRST COUPLE OF MONTHS.

Apple, where is the fix? The official fix is taking far too long. I love all my Apple products, and I'm a patient guy who normally never comments, but this really is disappointing. Apple's poor record of bug fixes is making Microsoft look good! - never thought I'd say that!

To anyone else reading this thread for help, my advice is: if you have a life and your time is limited, don't bother with all the advice/fixes, they're all temporary. What you really need is the proper Apple fix. In the meantime, maybe buy a Windows computer to tide you over?

That's the point. I totally agree.. I updated my all new iMac and thank god i had a time machine backup and i got back to Mavericks so that i can use my Mac.

Very disappointing Apple...
