wifi keeps dropping since Yosemite upgrade

Both me and my husband did a clean install after wiping the disc and it's still happening, if I turn my Wi-Fi off the mouse works fine but as soon as I turn Wi-Fi back on to work my mouse stops(Bluetooth) I did a 62 mile round trip yesterday for all this still to be happening starting to get cross now. It's really messing up my"experience" with Apple

I don't believe this is a wifi-specific problem. I believe it's a Safari-specific problem. My issues tended to arise when I was doing a lot of downloading in a short period of time via Safari. After a few downloads my connection would come to a screeching halt. Today I switched to using ethernet with the wifi turned off and the same exact thing occurred. So, I then tried to recreate the situation via other browsers and I couldn't do it. Neither Chrome nor Firefox had a problem no matter how many files and websites I tried to visit at even an accelerated pace. I then switched back to Wifi and had the same exact results: Safari would crap out within 30 seconds to 5 minutes while the other browsers had no problem at all. So, my conclusion is that whatever the connectivity issue is it seems to be related to Safari.

FYI, my tests involved opening up at least 30 tabs at one time and then option-mouse clicking to download as many media files as I could from each of the tabs opened. Safari was the only one that had any kind of issues at all.

I don't think it's a Wifi-specific issue. I think it's a Safari issue. I've come to this conclusion after switching to ethernet thinking it would solve the problem.

My problem generally occurred when I was doing a lot of downloading while surfing. It seemed to happen more with video than with pics. The solution had been to toggle wifi off and on. This worked for increasingly shorter and shorter periods of time before I'd have to repeat the step. The same problem occurred when I was using ethernet with wifi turned off.

So, I tested different browsers to see if I could recreate the issue and no other browser had any kinds of problems. My test involved opening at least 30 tabs at the same time and then option-click downloading as many media items as I could as quickly as I could. Firefox doesn't have that command other than a right-click menu option, so, it didn't have an issue since it would download faster than I could attempt to jam it. Chrome has that function and no matter what I did I couldn't break it. I then switched back to Wifi and I got the same exact results.

So, my conclusion is that this is a Safari-specific issue and not a hardware issue.

I don't use Safari. Chrome exclusively.

When I started having this problem, I tried Safari and the same thing happened there as well. The thing is that it is random. It may work well for 10-20 mins at a stretch or start dropping out in seconds.

I don't believe it is HW issue either .. I still think it is a WiFI SW (drivers/configuration) issue.

I also still believe it's Wi-Fi and Bluetooth, I wasn't running safari just in my iPhoto and my mouse continuously kept dropping out,i turned my Wi-Fi off and it worked flawlessly, as soon as I turned Wi-Fi bank on mouse started playing up again, we have also done clean installs with yosemite and still happening.

Indeedbeta release 10.10.1 seems to be better but far from perfect for me too on my '09 Macbook but I am still seeing occasional problems with Wifi and more worryingly Ethernet too where for example Ethernet in system preferences says wierd stuff like it is using a self-assigned IP address and can't connect to internet (when connected direct to router), then restarts seem to make it ok. Am very concerned Apple if Wifi is broken and fall back option ethernet is flaky too.

Without the patch on an iMac mid 2011, ethernet is impossibly flaky for non admin users too. System prefs seem to say Ethernet is OK, with an IP that refreshes when I renew DHCP, but there is simply no connectivity to internet, or to be more precise it seems to load half of one home page then connection breaks. Feels to me like Yosemite does not like switching users, resuming from sleep.

I've deleted on my stock Yosemite iMac pref plists, created new locations, deleted and reinstalled network services, PRAM and SMC resets, and frankly draw the line at disabling dual band on my router as the whole point is some devices close by need one and devices further away another band. And I have problems enough with wired.

I went back to hardwired keyboard and mouse to remove any Bluetooth chatter but still lose count of how many reboots of routers and macs i do to get a connection. Shame on you Apple. Forget fancy Yosemite eye-candy. Every single user wants a reliable connection to keyboard, mouse, and internet and you've failed me, my family ("Dad, the old PC always worked"), if I have to disable Bluetooth, reboot constantly and run a 80 foot Ethernet cable through the house through doorways to try and get a connection to write this!

Many have commented already but I want this to count as a +1 from another Mr Angry.

Dear Apple,

Time to fix this problem and quit dumping an OS that is not ready for primetime. That's so, Microsoft.

I used to upgrade my Apple OS without giving it a second thought. No more. Glad the wife has waited, wish I had.

If you a separate Admin user account, log into it if you haven't done so for a while.

I had the same problem for a few weeks following my upgrade. I moved all 4 iMacs (2 on the same desk running desk off the same AirportExtreme router) to Yosemite, and only one has had problems. Ironically enough it was one of the two that are side-by-side. I have tried about 3-4 of the solutions offered in these forums from SMC resets to bluetooth tweaks to DNS overrides. None really worked for more than a day at most.

But I did accidentally stumble on something (decidedly not a deep plumbing fix) that seems to have worked for me. The machine that was having the problem is one that is more of an open family computer, so I have an Admin user for me and a general user that everyone logs into for daily use. I never really log into the Admin user, just use passwords for installing apps/updates as needed. But I did log in recently (first time since upgrading to Yosemite) to set up a new user. And when I did, I was surprised to see the final Yosemite upgrade/install/optimize process (grey image of screen with bullet points) starting to run.

Ever since, running perfectly. No other changes, updates or fixes. I happen to run all three of the other machines from the Admin user account and these are ones I never had an issue with.

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Feedback

There are definite bugs in Yosemite that need to be addressed by Apple. Multiple people are experiencing Wifi issues with fresh installs of Yosemite.

I was experiencing consistent Wifi issues after a fresh install of Yosemite. I validated that it wasn't my computer or router by doing a fresh re-install of Mavericks. Wifi works flawlessly under Mavericks but always fails under Yosemite. No other software was installed as part of this test.

Here is my configuration:

Model Name: MacBook Pro

I can connect to Wifi to an insecure BT Hotspot - but it is only at 4 Meg. Previously, I was able to get 40Meg via Wifi. The PC also struggles to run several open programs now (4GB RAM) - previously it was super fast and capable.

Yosemite is a pile of S%&*t. Apple have let us all down badly - I will not buy another one as they are just as bad as Microsoft now. The adage - 'It just works' - is now laughable. So why pay premium prices - a Lidl special Laptop is just as good.

I think this latest fiasco will probably not do Apple any harm in the short-term. But they have clearly gone down the same route as other massive corporates. Get a good reputation, a good product... then just make them in the far east for pence, destroying quality. But in the longer term, they will not be able to retain the premium price tag as they just like everyone else.

Apple - go F%^$k yourself.

You can always replicate this test by rebooting in safe mode - which uses neither Mavericks nor Yosemite and that can give you a read - is your wifi problem related to Yosemite. There is likely something going on but hard to understand and all these remedies I read.... not sure there is a generalised robust solution here. But reverse to Mavericks and wait for the next OS is fiddly but should work. It is a pity that Apple does not enter the conversation. My own results are really mixed. I have some great performance from my Yosemite MacBook Air - at my university where the wifi network is updated I am getting 100- 150 MBS down and 100 up. Through thunderbolt, I can get 600-700 down! UK universities have a great backbone. But in my office, where the router is still maximum 55 MBS I get much worse performance than was the case with Mavericks. So where the wifi network is "good" Yosemite performs well, better than Mavericks perhaps. Where the network is weak, I think Yosemite is less tolerant of it than its predecessors and it keeps dropping. At home, I have bought Apple's router and that has made a difference (at a cost) and retired a very old mac mini and that has improved wifi performance as well. Let us see if the updated OS will fix these problems. I suspect it will for many but not all of us.

Same as everyone else. Dropped via upgrade, and when I did a clean install (15'Macbook Pro Retina/2012) same problem. Took off security on Router (MAC Address only) and seems to be stable. Very frustrating... Oh, and Bluetooh is off. When can we expect a fix to this, and the host of other problems encountered with Yosemite (machine name keeps changing? multiple Note items? etc...).

I've fixed the problem by connecting to a 2.4 Ghz wireless rather than 5 Ghz. This worked for every laptop in the house that had issues. Speed seems fine as well...

Anyway - this worked for us - was a simple change on the router.

Hi All,

I had the same problem here but i think its working fine now (hopefully it'll continue like this),

the problem was in the network router itself, i just re-configure my adsl network and everything just fixed (thnx god) 🙂
