Slow internet connection after update to OS X Yosemite

After Yosemite install, Safari seems buggy and slow. Very slow. Unbearably slow. Sometimes nothing loads at all. Mac Mail also sometimes decides to go all exclamation-pointy and stop getting new mail. I find:

a) Chrome appears to run faster - seemingly almost normally

b) Turning off bluetooth, which is remarkably inconvenient because I have a bluetooth keyboard and trackpad on my iMac, right this second sped up my download speed from 12Mbps (it's been a lot slower than that by the way) to 22.68Mbps. It happened instantaneously.

Please may we have an update or a patch or something, Apple. We got Yosemite for free. I wouldn't have minded paying if it didn't bug up the Most Critical Thing (the INTERNET).

I gave up on it. I managed to fix the wifi connectivity issues, but wifi bandwidth remained terrible. At least it didn't drop on me, I could use the internet again, but attempting to stream anything with wifi would occasionally start to stutter like the bandwidth was being choked, but it was local streaming so I know it wasn't my ISP, it was my wifi.

I've been having slow internet speeds since yesterday. I read through this thread and tried a few things. The thing that worked for me was disabling the Handoff in Preferences. As soon as I did that, speeds were back to normal. I can't use Handoff until I get this issue fully resolved, but at least I can work now.

Given US Courts' propensity to award huge damages at the drop of a hat (I know as I used to be an insurance underwriter), Apple would be terrified to admit openly to any fault. Doing so, could leave them open to some bunch of ambulance chasing lawyers, starting a class action suit. In the UK, Bring at the cutting edge of technology and a developing product can be cited as a defence but not in most states of the USA.

I wonder if we're going to find out that we all have some third party app that is in conflict with Yosemite. DNSCrypt, Freedom, EyeTV (TV Guide) some leftover piece of a utility... ?

I saw the post to disable "Handoff" between devices. Many have stated that this new feature of Yosemite is really cool, but there are some major oversights here:

1. The option to enable/disable is not available for all users, it simply does not exist. (Strong work there Apple)
2. Workaround 1 Connect your iPhone to iCloud and laptop to iCloud, pair them, then disable on both devices. Unfortunately, I do not have an iCloud account, nor do I own an iPhone. So do I have to go buy a device, just to connect, so I can disable it? (Again, Strong work Apple)

Can someone tell me the services that are related to this so I can simply disable those services to try and fix this?

Here is my problem, I am on a 120MB connection that has been reduced to dial up speeds (WIRED and wireless). I have tried every possible solution thrown out there and anywhere else I can find.

I would love some ideas to try from APPLE, since they obviously don't have the in-house talent to test, maybe I can at least be guided in the right direction to test myself.

ANY help is greatly appreciated, really anything, ....anything at all. ....crickets.

Like MrBlack, I wondered if there was a conflict with a third party app and my suspicions also fell on Eye-TV. However I have disabled that as a login item along with everything else. I have checked with the applications utility that nothing is running that should not be and Internet connection is just as bad and flaky as ever. I think it is a pure screw up with Yosemite. Since Apple had multiple reports of this from the first Beta, I am surprised that either it was not fixed or that the release was not delayed until it was, given that connectivity is now such a large part of the way most folks work.

My Safari / internet was running substantially slower after upgrading to Yosemite. My iMac is wired directly to my Apple Airport Extreme. Speedtest.net showed my download speed where it always has been at 30-35 megs/sec. But Safari was poking along. I've been running Sophos anti-virus. Somebody mentioned to try turning it off, so I did. Now my iMac is SMOKIN fast on the interwebz. But I hate to not run Sophos. Hopefully Sophos will fix their conflict problem soon.

greetings all!

I've been following this thread for a while now. I can tell you and promise you that this issue is not restricted to wifi. it happens to me with a WIRED cconnection as well. Also, it has nothing directly to do with a third-party app such as antivirus or TV anything. I don't have an antivirus or use any of the third party programs mentioned. I'm not using any third party networking programs. Download speeds are just plain insane. Often dial-up would be quicker. that's not an exaggeration.

this is horrendous and MUST get fixed.

I have the same issue on my Mac Pro with a hard wired connection.

I am going to add some additional info for those looking to fix themselves.

Here is a list of my stuff, even though I don't think it is app related, since it is happening on 4 of my 12 machines here at the office. (That is 33% for those of you keeping track)

We use the following apps that are fairly consistent across multiple machines:

Skype

VMware

Firefox

Chrome

We tried removing these, rebooting and tested the machines again, with no luck.

I thought it might be a caching issue or a writes permission, since I can attempt to load a website and it will hang on loading, but if I refresh the same page while it is loading, it will "load pop", which many developers are familiar with when choosing to load until the page completes. Larger sites and sites with load balanced servers seem to be far worse, Amazon, for instance is almost unreachable on any of the machines without persistence.

I tried most fixes, rebuilding the caches, rebuilding the connections, creating new connections, hard wiring, setting the router on my computer. I even crated new profiles to see if it was related to the profile itself. I tested with guest accounts, admin accounts, I even tested with multiple accounts within windows using vmware.

I am trying to think of what other programs use the connection itself or access the connection (which is probably why some lucky people who had antivirus can now disable it and it works). My assumption is that it had control over the connection prior to the update, then they were able to disable it after, which is why it is working for them. Same with some of the bluetooth issues.

In researching that concept more, I did find that Apple decided to introduce their wonderful spyware into this release that sends your searches and data back to them in real-time. This ****** me off for one, but for the other, it made me think that this is probably the reason they are so hush hush about what the problem really is, for fear that they will get even more negative publicity than they already have from it. BTW, if you are interested in turning this "Feature" off (which I HIGHLY recommend), there are instructions here: http://thehackernews.com/2014/10/Aplle-Mac-OS-X-Yosemite-location-privacy.html

Keep in mind that this IS profile specific, so you will need to disable on every profile.

My next move is to install antivirus and disable it to see if that helps, and I also have a USB wireless dongle to test and see if a newly installed hardware component will work better. (I will post back my findings)

I went to the "Genius Bar" and they did say they are having luck fixing it for some, but in each case, it was usually a format and reinstall that did the trick. I would like to think there is another way, so I am hoping that others can add their configurations and testing so we are not duplicating efforts and can leverage each other for a faster remedy to this AWFUL beta release they call Yosemite.

That's the thing. People think it has to do with wifi, but problems exist even with hardwired connections.

I am having this issue too on a late 2013 pro retina 13". It's ridiculous how apple seems to be ignoring the problem which is obviously widespread!

UPDATE - WORKING !!!

I am very happy to report I solved my issue and am happily speeding along again.

I tried all of the above things, including (most recently) downloading and installing Sophos and then disabling it, which did not work, btw.

My last step before the sledge hammer was:

I ordered a tp-link usb wireless adapter from amazon and when it got here, i found out that it was not mac compatible!!@#$%^!

so.... I used my windows install, in vmware, to install the driver and test it in windows. As soon as the driver was installed on the windows vmware install, everything worked in both windows and mac instances. speed went from .3 Mbps to 15.3 Mbps

My recommendation is to get the drivers for your device, save them locally, uninstall the hardware and reinstall. Or, try what I did, and find some random additional networking device, install it and hopefully it will overwrite the configuration and unbreak your $3000 paperweight.

Good luck and Godspeed!

It was me that mentioned the Sophos issue but I found a few references to it elsewhere which is why I tried it. I was running wired to my (cable/fibre) superhub router and losing 100MBs - yes that much. My speeds have been fine but large apps still time out on the iTunes store on and off.

I'm running without AV but have superb speeds so worth the risk as I work in IT anyway and take the usual precautions.

There have been several release from what I can see of betas and 10.10.1 is out in one of the beta programs from reports, it will be interesting to see if that solves anyone's problems.

In the meantime, I'm having no end of issues with my iPad 4 in iOS 8 freezing (not even responding to home being pressed) in Safari, Facebook, Tweetbot and the Photos app so I'm not out of the woods yet.
