OSX Yosemite Wifi issues

Yeah, i think that if there was a real end-user fix, it would have been discovered.

I got mine to work by disabling dual band switching on my Airport. But my bandwidth with Wifi streaming still chokes.

Despite the fact that I have an Apple computer, Apple router, and AppleTV and it all should have worked right away-there was no better environment for Apple products to work in!

I don't mind troubleshooting, I work in IT after all. But the nail in the coffin for me was Apple's failure to respond, acknowledge, or fix this issue-and-the fact that this issue existed since beta and was released to hit a launch date anyways.

It was with a heavy head that I ordered a Windows PC. It took me weeks to pick one out. Half of them look like electric shavers, and the rest look like a NASCAR. With Macs, my annual choice was easy. Buy the new one. Done! With PC, ugh I ended up buying a "gaming laptop" to get the specs I wanted. So now I have a super awesome, high powered machine with a freakin' bright red Dragon on the lid. Shake. My. Head. but I did what I had to do to.

I've been suffering from this same ailment since I upgraded on Thursday. After much gnashing of teeth (PRAM, SMC, reinstall of Yosemite, etc. etc.) I finally **RESOLVED** it by creating a new Network Location.

*under Network Preferences

*Click drop-down for Location

*Create a new location.. (I called mine "Internet")

*that's it!

hope it helps you too

This helped me. Thank you

Me too, having same issue with 10.10.1 -- I just upgraded from Mavericks 10.9.5 straight to Yosemite 10.10.1 on a Macbook Pro 15" (early 2011). Had no wifi problems with Mavericks. Now suddenly I cannot stay online for more than new seconds. I had to physically connect a cat5 network cable to the router in order to be able to post this! APPLE: HELP!

I don't know how long this "fix" will last, but I opened my router settings and switched the WiFi radio from channel 11 to channel 10, rebooted the router, and reconnected. Ever since I have had WiFi connectivity. No reason I know of why this would need to be required or why it would work. The prior channel worked fine on Mavericks. ???

Having the same issues, and tried everything mentioned reported on the internet, I think it all boils down to problems with interference of routers. This also explains a lot of the supposed solutions. Airport picks a router and configuration, however, if there are multiple routers and settings to choose from, it can pick suboptimal configurations. This can result in degrading performance or even loosing connection.

If my hypothesis is true, then try your mac (book) on a location where there is little or no interference possible from other routers (can be difficult these days). You can also download and use a wifi explorer/sniffer that gives you all the routers in your neighbourhood.

I am no expert, but I think this could really be the issue.

Yes, but if they changed the configuration options of the wifi then this could become an issue. Just go to a place without possible interference and try then if the problem still persists. I have noticed that working in my hospital with lots of routers, connectivity is a huge issue, whereas, at home things run smoothly.

If this doesn't work out for you, I am wrong.

run airport in terminal to find local channels

-I = info about your connection

-s = scan for local wifi channels

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airp ort -I -s

The only BIG problem is that you cannot force Airport to select a specific channel or BSSID. Tried that, but Yosemite, being stubborn, switched right back to a channel with (I think) interference. In previous os x you could actually pick a specific BSSID.

Hi, there:

I just wanted to say what has worked for me since I updated to Yosemite 10.10.1. I have a MacBook Pro (Retina, Mid 2012) that was having Wifi problems also. I went to System Preferences > Energy Saver and turned off the Wake for Wi-Fi network access. Since I did this my Wi-Fi problems have disappeared. Problems included disconnection every five minutes, slow downloads and disconnected downloads.

I know it may not be the standard solution for everybody but I wanted to help a few of you that may find this to work in your favor.

I have a slightly different problem.... My macbook pro has slow wifi connection 2.4 (0,5 mbps) and a better connection using 5G (20 mbps).

When I put my bluetooth off, my 5G connection drops to 10 mbps! and my 2.4 goes up to 8 mbps!! ????

It is my first macbook, I just bought it and it is the biggest piece of crap I ever had!! I come from a normal windows laptop (an old one), and I NEVER had any kind of problems that big on a new windows release!! Incredible!!

Everyone gives solutions, but no one has a real working solution! Apple doesn't react at all!

Anyone interested in a brand new macbook pro??? I give you a nice price!!

Yeah! After update to 10.10.1 I have the same problem. When bluetooth is working, wi-fi is not working. Why? Apple, are you serious? Yosemite is real amazing OS. Most powerful! I love it! Sorry, guys, this is incredible

I have MacBook Pro 15'' retina (mid 2012)

That is the point, Apple doesn't react at all 😟

You have absolutely no idea what you are talking about. So let me talk for a sec.

1) I am a developer and use developer previews. I beta test for a lot of companies. I know of 3 companies which are participating SO actively in bug solving as Apple. Only 3.

2) Based on THIS very thread, I received an email from Apple Care. They asked politely if I would be willing to participate in a telephone conversation so that they could gather material for a repro-case. I have had two conversations with them pertaining to THIS here very issue. So far. And I am VERY sure that they don't just call one person but many. I'm in Germany they in the U.S. I have yet to personally experience ANY company reaching out, internationally over the phone, to gather diagnostics to repro a bug. Based on what SOMEONE, in this case me, was writing on a public non-beta forum.

I am NOT a fanboy in any regard. I use what I think is best. NOT because it has a shiny surface or is packaged nicely. Be that Apple or Microsoft.

But to claim that Apple doesn't care about their product and simply don't react is simply put; not true and does not reflect reality.

Just so that you can understand HOW difficult it is to solve a bug like this one which is NOT occurring reliably. It has been 48 hours since I was asked to repro the case and the past 48 hours my Wifi has been working 100% as expected. And I am REALLY trying to repro. Set WLAN to 2.4 GhZ, connected 3 different bluetooth devices, moved as far away from Airport as I could, put iPhone next to MBP etc... ALL the things that would typically repro the case.. Only THIS time, the devil refuses to rear his face... I am putting the computer to sleep waking it... Nothing... WiFI and BT are 100% steady. I am sure that eventually it will happen again... And then I will send in the diagnostics...

So - as you can see it is not very simple to produce a clear-cut case and tell Apple; Do this and THAT will happen....

Such a scenario is a worst-case scenario. If you can't find whats broken - it makes it pretty impossible to fix... Even though you would like to.

Think about that for a minute before you jump to unreal conclusions !

I, too, received an email and phone call from an Apple tech, following my couple of comments on this message board, yesterday. Spent almost two hours on the phone, and we went over everything - with me trying to explain what exactly has been happening and with him translating it all from Average User to People Who Know What They're Talking About.

First I couldn't decide if I should find the phone call and emails creepy and 1984-ish, but then I thought it was actually pretty darn cool that they'd reach out to a very average user (meaning that it's highly questionable whether my extremely limited knowledge and understanding of what's been going on with my MBP since installing Yosemite - other than "I can't use my wifi anymore, give me my wifi back, I need it, wawawaaaaaah!", - is going to get them even a millimeter closer to an eventual solution,) and invest quite some time and attention into trying to figure out what has been causing my particular issues (which is probably something just slightly different than what's been causing a lot of other people's problems.)

OK, that sentence is way too long... Anyway, my point is that while I cannot disagree with people who say that it wouldn't be insane of us to expect some sort of public acknowledgement of the problems, I can attest to the fact that they are, indeed, trying to fix the issues. I would think it would be highly unlikely that they'd be reaching out to and spending all this time chatting with random users, you know, just for the heck of it. 🙂

Good point. It would be difficult to tally the possible combinations/ permutations reflecting the multiple network configurations a user has coupled with the multiple 3rd party apps sitting in the user startups.

let's start a new thread:

Click here if your Wifi is working under Yosemite

😝

In my experience, particularly with the "patched" version of the bug (i.e. the patch made it worse), is that I can leave the machine (mid 2009 MBP) running for hours with only imessage running and mail app running and everything appears fine. However, when I start using browsers, particularly when streaming videos and have several browsers open (I need this for work), I find that the connection disappears. I bought the new airport express last week to ensure this was not a router issue (previous airport/time capsule was 5 years old).

Trying to click on the airport icon and selecting (turn off/turn on etc) does not allow me to reconnect. I have had some success using terminal to control it (networksetup -setairportpower en0 on; networksetup -setairportpower en0 off, etc). That may work for a while and allow me to finish downloads etc. But a restart is generally required shortly afterwards.

Have also tried the "new location" strategy mentioned previously, deleting network config folder, PRAM & SMC resets, deleting all wifi networks. I haven't turned on bluetooth in months.

In summary, the wifi is most volatile when I am using multiple browsers and actively downloading/streaming/browsing. Seems most stable when it's not being actively used.
