Q: OSX Yosemite Wifi issues
-
Apr 25, 2015 12:14 PMby casey-al,Again, a follow up to my previous....
Fixed the residual bluetooth issues by doing the following:
First
I went into System Preferences -> Network and deleted the Bluetooth PAN and DUN entries
If you don't see any, you may need to add them in and then delete them. You can use the following Terminal command to see if there is an orphan DUN or PAN running.
networksetup -listallnetworkservices
If so, add the orphaned items back into Network Settings (make sure you click Apply) and then delete them again.
Second
This last step may be unique to me -- but it appears the 10.10.3 update caused my bluetooth to distrust the keyboard (although my trackpad was working).
The suggestion at this link fixed it.
Finally
I was hesitant about the first step because I thought it would disable my Bluetooth tethering (or something else), but it didn't. Everything is working for me now (or until the next OS X update I suppose).
If you need the PAN and DUN however, perhaps rebooting and adding them back would do the trick -- but since I haven't found a need, i can't test that for you. Perhaps others will advise you here.

Apr 25, 2015 1:37 PMby bentryan,Having the same issue, wifi drops out at least 10 or 15 times an hour, sometimes it drops and doesn't come on. My Macbook pro is late-2013 retina display, Specs are: 2.4 GHz Intel Core i5, 4 GB 1600 MHz DDR3,Intel Iris 1536 MB, 121 GB Flash Storage. I have tried every solution out there and still seems not to work. This has been an issue ever since I upgraded from Maveric to Yosemite. Can someone please help

Apr 25, 2015 1:49 PMby uffe_17,Same here.
WIFI - still requires re-boot 50% of my MBP late 2014 of the days when I get home from work (where I use ethernet and disable the wifi) and try to use wifi. Sometimes it works when I get home and use a checkpoint vpn connection, but stops working after I disconnect the VPN.
Bluetooth - Not possible to see the Iphone 5 from the MBP. When searching for bluetooth devices the only thing that is seen is the old Nokia 27xx something classic.
Airdrop still the same problem with no visibility between the iphone and MBP
The only thing that seems to have been fixed with the 10.10.3 upgrade is that I now can access my airport extreme to login/change settings there. That was impossible in the earlier versions of Yosemite.

Apr 25, 2015 3:56 PMby jndupuis1,Hello, A little something that may help all of you with Bluetooth. Wireless keyboard, Magic Mouse and Magic Trackpad problems. They require a lot of juice. I personally was going through Alkaline batteries 8 pk. to be exact in about a month. Replacing when System Administrator's Trackpad reported 20% or less.
Little known secret alert!!! Apple Battery Charger Kit! The best $30.00 bucks you'll ever spend. Increases usage big time. 2 to 4 hours use a day using my Trackpad with these batteries gives me a month easy on 1 set of batteries, kit comes with 6 ea. Bluetooth response is better and the system wide performance is increased as well. Including Wi-Fi.
Early on in this gazillion page Thread we posted temp fixes, and, well, that is all they are. Including, but limited to deleting and re-establishing Kext. One major hurdle to overcome is addressing the router. I found instead of using 802.11n only, "mixed" is the way to go for me. As well, WPA/WPA2 Personal. Channel, I choose Auto. This config is for my 2.4 GHz and 5 GHz. My Macs are connected to 5 GHz.
Another issue that creeps up is Local Network renaming itself. I addressed this issue early on in this Thread. Simply go to System Preferences>Sharing click Edit and name it something other than your computer name. Click OK exit out and restart your computer for it to take effect. Simple enough but not enough for me. I then went into System Preferences>Network>highlight Wi-Fi then click Advanced button. Click the WINS Tab you'll see your new Network name. Change WORKGROUP to HOMEGROUP then click OK and APPLY then restart for changes to take effect. I shut down, plugged into Ethernet and repeated this process in both Ethernet and Wi-Fi. You can shutdown and disconnect your Ethernet. Now when I log into my router, I see both Ethernet and Wi-Fi under the same computer name. Works fine, lasts long time, for me. I use Ethernet for router config only, routers do not like you to use Wi-Fi for that, plus, it is totally unsecured. Mac Mini late 2012 running 10.10.3 with no issues. Hope this helps. !!!BUY THE APPLE BATTERY CHARGER KIT!!! It's the best Apple product I've bought besides my USB SuperDrive. Cheers All.

Apr 25, 2015 4:20 PMby jndupuis1,Okay...so I forgot to mention that I performed a complete erase of my HD and did a clean install of 10.10.3. I also made sure I immediately downloaded all of my purchases just after set up.
All with persistent Bluetooth and Wi-Fi issues that are unresolved by any user method seriously need to make an appointment with your nearest Genius Bar. Diagnostic is free for us Mac owners. Wi-Fi and Bluetooth comfortably reside on the same Broadcom card. Have the Apple Store check it out. You may have a Broadcom lemon. Give them all the info you can. Just because it is working in the Apple Store doesn't mean it is working. Cheers!

Apr 26, 2015 3:47 PMby Mr. Luigi,I couldn't bear the thought of reading though all 204 pages of this discussion to see if anyone else has discovered the following prevents wifi from disconnecting on Yosemite 10.10.3.
There are applications which I am forbidden to name by the moderators whose sole purpose is to prevent your screen AND COMPUTER from sleeping as long as you keep the application on. Usually activating these applications is done simply by clicking on an icon on your menu bar. Turning off the application is as simple as clicking on the icon again. I use one of them. Great for presentations as you don't need to tap the track pad regularly to prevent the screen from going black. Why do I mention this? Because I noticed that every time I used one of these applications where I teach (enterprise network) I never lost wifi. (Otherwise I lose wifi connectivity multiple times an hour). I've tried this a couple times now to verify. Same result. Wifi endures.
It appears, at least in my case, that if I don't let my computer sleep I do NOT lose wifi in Yosemeti. BTW, when I'm away from my computer I turn the screen to black using the brightness keys on my keyboard. No need to prematurely wear and tear my display (15" 2014 retina MBP).
If you do not have one of these applications you can, of course, go into preferences, and manually set the energy saver to never let the computer sleep. Since the screen saver functionality has no effect on wifi, you can keep it at 15 minutes, or whatever setting you have.
Maybe this magic just works for me. But I thought I'd share just in case.

Apr 26, 2015 3:54 PMby Sparkleberry,A script will keep your connection alive if that is an issue for you.
I have always used the following, not because the WiFi drops but one of my VPN providers did
AppleScript that keeps the VPN connection alive.
on idle tell
application "System Events"
tell current location of network preferences
set myConnection to the service "NAMEOFYOURVPN_Setup"
if myConnection is not null
then if current configuration of myConnection is not connected
then connect myConnection
end if
end if
end tell
return 120
end tell
end idle
Here is one source of the script

Apr 30, 2015 9:04 PMby huuanito,our mac book air finally came right after a PRAM reset. Haven't had to do that since system 6, *** apple, are we reverting?
We had been having wifi troubles since 10.10.1 on the macbook air and around the same time on an iphone 5. Updating the router did not fix things.
10.10.3 on the mac book air fixed it for a few hours then it dropped out completely and would not connect again at all no matter restarts, reboots of router or what. The PRAM reset fixed it and it has been solid now for two days (just like it was for years before software updates broke it).
The iphone was intermittent connecting to wifi since around september last year did not come right til ios 8.3 a few weeks ago. OI VEY! I'd complain to apple but I'm not a beta tester. They should test stuff in house on a variety of devices BEFORE releasing the updates.

Apr 30, 2015 10:51 PMby PRiSTiQUE,This is simply opening up a security hole in your computer, it has nothing to do with generating a stronger wifi signal. I highly recommend NOT doing this, as it will not change bandwidth issues from a router whatsoever, and I presume all this does is allow applications from other computer in your LAN to connect to your computer.

May 3, 2015 4:02 AMby tomstephens89,I am the OP of this thread and just giving a quick update.
Like I said apple contacted me for diagnostic logs etc a while ago, and a couple of months ago I sent the wifi router which I first noticed the problem with to them in exchange for an Airport Extreme (which works fine by the way, excellent connection).
However this week I have been troubleshooting issues with high latency / packet loss on one of our Wifi networks at work (which is a Ubiquiti Unifi system) and the ONLY device that has problems with latency and drop outs is my Macbook Pro running Yosemite. 3 other laptops I had running next to it had no problems at all!
So there are still issues with wifi and Yosemite im afraid Apple!

May 3, 2015 4:19 AMby osihara,Thanks for that. I'm also still having ongoing issues. i was contacted too. They haven't asked my my router. Wish they would. I'd like a new one ... Still Would be nice to have some conclusion for this issue. Feel bad for them, I'd hate to be the one to solve this. Not a single user idea has had any effect at all for me. Glad that some have had success.
