Q: Yosemite 10.10.3 Wifi/Bluetooth Issue FIX

Eh it kept happening. I ended up completely resetting my router to its default settings then reconfiguring it without doing anything special. My connection issues have not returned.

Perhaps there are compatibility issues from this update. I'm still irritated because it worked perfectly fine before I updated to 10.10.3. I haven't messed with my router settings in nearly a year.

MOTHER OF GOD it totally worked for me. I had the same problem after updating to 10.10.3. I spent days looking for one solution. Thank you very much

This is definitly working for me ,

"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 on http://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."

Well, it did not last longer than a couple of hours. So did my patience, Apple.

Yes, it worked for me too, so far! At first I didn't think it worked as all I turned off was the cell phone calling feature, but one day later I went and turned off ALL of the new Continuity features, I cannot street how important this is ALL OF THEM. Including handoff, SMS messaging from Messages, etc. And voila, it works now! Thank you all so much!

One thing that amazes me is how little Apple cares.  I fought with WiFi when I bought it in 2013, and listened to Apple Support tell me to have my university change all of our routers to Apples ones (no, really, he did).  And now, May of 2015, I again cannot go more than 5 minutes without having to disconnect and reconnect to get WiFi back.  And now that my support has run out, they want me to pay them to tell me how their problem is my problem.  Sorry for the venting, just very, very frustrated.  And I just did it again so I could hit 'reply'.

I had a problem with Bluetooth not working. Based on your tip went into FaceTime and selected Turn FaceTime off.

Next I went into Bluetooth Preferences it was finding devices again.

I turned FaceTime back on and enabled all features in Preferences and Bluetooth connectivity is still working.

I switched off everything on FaceTime and the problem was semi solved. I was able to tap onto the Wifi but it still took time before I could get Internet connectivity.

I read elsewhere about how iCloud seemed to be a problem for some users so I pretty much switched it off but only left one feature running i.e. Find My Mac and Keychain. For now life seems good with a stable internet connection. *Fingers crossed. Eyes crossed. Toes and fingers crossed too*

Thank you so much!!!!!! FINALY!!!! strange to know that all these "cool" features (that i never use anyways) are the cause of problem.

My bluetooth was nonoperational and I applied the info about shutting down the facetime integration with the wifi (exc). thank godd!! I was about to pull my hair out!!  But,, Hells yeah!!  I disengaged the facetime BS  and shutdown. Now restarted and Bluetooth WORKS!! yay!! I was about to see a Genius for way more money then they're due. BOOM thank you!

Thanks God!!! Amazing!!!

Your fix work for me, thanks romboface.

works... sigh of relief.  That was really annoying.  Thanks

edit

argggh... five minutes later and its back again!

YES!! Worked like a charm, immediately!

FYI I'm on 10.10.5, and my magic mouse has been unusable unless I turned off WiFi on the computer.

Tried Repairing permissions, changing Wifi channels (both 5 and 2.4 GHz), moving the router around the house, diagnostics, nothing worked.

This did it. Thanks so much!

The problem is only with the Magic Mouse. Others work well !!
