Q: OSX Yosemite Wifi issues

As it seems, anything changing to the Yosemite network setup will render it stable for an indefinite period of time. I hope yours will stay so. But don't be disappointed if it isn't. And this goes for anyone here.

Hate to say it guys but after 2 days of things being back to normal I am back to drop outs.

I am now connected again back to the network via ethernet and even then when the mac

enters sleep mode it drops off the shared network and won't pop up again unless I reboot it.

I returned my laptop to Mavericks and everything network wise is back to normal with that.

Yosemite has a lot of nice things to offer but none of it is worth the price of losing stability

in your home network.

These issues should of been found on BETA prior to Yosemite release.

That was exactly the point I was trying to make in my previous post, OzziesMAC. Please don't shoot the messenger...

OzziesMAC. I agree. The BETA should have caught this at the get go.  I use an EA3500 Router and Motorola SB6141 Modem to take advantage of GB Ethernet. All my network settings for my router and the one's I apply in Mavericks. They hold up and are stable. Guys, I apply these settings in Yosemite and it just holds up long enough to make you think it's going to work, but only problematic at best. In Mavericks, on my Mac Mini and my Apple devices I connect to 5 GHz to avoid SNR in 2.4 GHz that has been mentioned. All my stupid "Smart" devices - printer, Android, etc can only connect to my 2.4 GHz. They have no troubles. Speaking for myself, I believe the "average" computer people now know more then they ever have of Network Settings. Hope the fix comes soon. Yosemite has great potential. Maybe we ought declare October as "Yosemite WIFI Network Awareness month". Just a thought to lighten things up.

I just tried something, which so far seems to be working. Go in to your Keychain access - System. Find your wireless network - double click. There are two tabs, Attributes & Access Control. Go into the Access Control and check "allow all applications to access this item". Mine was defaulted on confirm before allowing access, which I think was knocking me off every time I tried to do anything.

 

I'm not sure, but this is the first 10 minute period I haven't been knocked off since upgrading last night. Good luck!"

I tried this and this solved my problem. Thanks a lot for sharing this solution. What I do not understand is that yesterday I installed Yosemite 10.10.2 and that did not solve my Wi-Fi issue. How come that this update could not fix the Wi-Fi the way I fixed it now?

I also would like to add what this Wi-Fi issue has cost me. I have spent two days searching for a solution. I could not find one. I bought an ethernet cable and a thunderbolt converter to connect the ethernet cable to it. All this has cost me 35 euros. Plus the time I have lost. Why? Because of a simple uncheck in Keychain settings. This should not have happened, or at least should have been fixed in the Yosemite update or Apple should have informed us well.

Yes, indeed, too much time consumption tweaking around with embedded settings in the OS X that, normally, no user has to worry about. All of this settings change will have to be undone or "Clean" install when Apple fixes these issues with Yosemite. I've looked at the Support Community with the Mac Pro, Mac Air, Mac Book Pro and the Mac Mini. All of which are experiencing a vast array of annoying problems due to Yosemite. The average User should be able to install Yosemite, config their Network, be it Home or Business and be up and running. It's a shame we are goofing around with settings holding our WIFI antennae and pointing our finger due South at 48 degrees to resolve an inherent problem embedded in Yosemite. I'm still running Mavericks until the powers that be fix it.

I tried the keychain solution, it did not resolve my problem. My wifi continuously keeps falling away and reconnecting, most of the time the internet connection is slow because of this and sometimes the system just about stops because of it especially after its been in sleep mode. I even have to reboot on occasions.

I am totally fed up with this issue and am disgusted that apple has not acknowledged or resolved this. I might as well switch back to Microsoft, after all I moved to apple because it "just worked", well that doesn't seem to be the case anymore.

Sorry I needed to fend my frustrations.

To disappoint all of you here, it turns out that my problem is also not solved with the Keychain trick. It did work for an hour and now for no reason I am stuck again. My Mac connects to the modem but after 10 seconds I start to receive no data or very very little data. I am fed up of the issue too. And yes I do not understand why Apple does not acknowledge the issue openly. This is too frustrating. I now wonder if and when actually there will be a solution.

I am honestly so disappointed in Apple and their failure to openly acknowledge the severity of this issue. I work solely from my Macbook and have been without wifi since the first day Yosemite came out, I do not own a back-up drive so reverting back to Mavericks would cause me to lose all my data and I have tried every fix suggested on this forum and elsewhere to no avail. This has cost me so much money and time, forcing me to lose serious work productivity and flexibility due to the fact that I cannot wirelessly access any internet.

It seems unbelievable to me that one of the biggest technology companies on the planet could let a product be released before it was ready for use (and the fact that they surely must have known of an issue such as this). I understand that they are probably trying hard to now fix the issue but their lack of communication about the issue to their customers is infuriating. This has cost me serious time and money and I am just plainly disappointed.

Apple, please put your wealth of knowledge and capital to use and finally fix this problem.

I am afraid most work arounds that are possible have already been posted and most appear to be unsuccessful.

This is a huge Yosemite Bug that not even the current beta seems to be able to fix it and have it stay fixed.

Option 1 go to your previous OS

Option 2 keep trying temp fixes and getting frustrated when they don't work

Option 3 Wait for Apple to announce that this is a new security enhancement to your wi fi network and its the way it's suppose to work.

Thats what they said when they killed FireWire with Mavericks.

If it is possible for you go2804, Boot Camp Windows 7 Pro or Windows 8 on your Mac. I Boot Camped Windows 7 Pro on my Mini and doing fine. I only use the Mac side because I have Microsoft Office for Mac 2011. Otherwise Boot Camp and the Boot Camp drivers are making my Mac Mini "just work". Like you and many others, just waiting for the go on Yosemite....and waiting, and waiting....

Folks,

It seems that Apple is abandoning us (those impacted by the BUG). Its been two months and I see no indication from Apple that they are even working on it. They have effectively muted the press on this issue. It seems they believe they can power through it. I'm not sure what to do at this point. Going back to Mavericks doesn't seem like a good plan. Frankly, I feel like a fool now for ditching Windows for Mac.  Microsoft may have its problems but I have never experienced this level of hubris.  

That's odd, I wonder who the Engineer who emails me every day from Apple works for then and why others are risking their peace of mind to improve YoUR OS?

I have some appreciation for Apple’s dilemma. Here’s the scenario I believe played out:

With iPhone 6 launching they pulled every available software engineer to help. Yosemite suffered.  But, they wouldn’t delay Yosemite launch because it had iPhone features. Let’s face it, mobile devices are Apple’s focus, not us Mac users. With insufficient testing they completely underestimated the impact of this bug. Further, I’ll bet that the changes to the networking protocol that created the bug are crucial to the local communication features. So, now Apple has a dilemma. They chose not to communicate the issue. Further, through innuendo, they persuaded the press to downplay the problem. Many of the users affected gave up and just purchased new routers. Through time, those affected decreased their public display of frustration. Apple decided they could just power through.

Now I realize they are still plodding along.  But, I also believe this issue will never be fully fixed. It’s now a war of attrition on Apple’s part. Those of us affected will eventually just buy a new router and move on. As someone posted before, it will eventually be explained as a new security feature of Yosemite.
