Q: OSX Yosemite Wifi issues

Running Mavericks with repeated WiFi dropouts with one router sine an upgrade a couple of months ago,
Problems with drop outs persisted after an upgrade to Yosemite.
Applying the Kext file in this thread solved the frequent WiFi dropouts
But there remained other issues with WiFi -
i) WiFi would drop if the laptop was closed and would not reconnect without a restart
ii) Sometimes on restart / startup the WiFi menu bar would say "no hardware found"
iii) Occasional dropouts occurred but nowhere near as frequently as before, i.e. one or two a day as opposed to every few minutes.
So I thought I'd back up the hard drive, erase it and do a clean install of Yosemite.
On restart "no hardware found", I trashed the system Config and restarted. OK. WiFi dropped after 2 minutes.
I give up.

WiFi loses connection to the router
4 bars in menu bar and WiFi says On
Turn WiFi off -
WiFi won't turn on again
System preferences>Network>Make service Inactive (WiFi).
Click: Apply.
System freezes. Every time. Only a hard power off can be used.

Oct 30, 2014 2:11 PMby kohls,I had the same wifi problem with my new MacBook Air after upgrading to Yosemite. Just got off the phone with Apple. It's a bit tricky, but here's what they had me do:
Turn off the computer.
Plug in the adapter.
Place 3 left hand fingers on R, Opt, and Cmd (I used my thumb for Cmd) and one finger of the right hand on P.
Press the power button with another finger of the right hand (don't press the others yet) and let the power button go.
Then quickly press and hold all except the power until you hear three tones.
Computer should start up with wifi on.
It's working for me so far.

Its the diagnostics that appear when you hold the option key then click on the wifi icon that I needed to run. This produces a report on the desktop that i have sent to Paul from apple.
Perhaps you guys should do the same and send in wifi diagnostic reports to apple support.

Then from your Mac, look for all available wifi connections, you should see something like "fliptale's iphone". Choose that and provide the same password you set earlier in your iPhone. Once connected, instead of the usual wifi symbol, you should see the hotspot icon instead (chain).
It will also work if your phone is on 3G but being on your local wifi is preferred.

Oct 30, 2014 6:46 PMby FlipTale,not sure if i got it. in ios 8.1 there is no "settings > personal hotspot" option. u should go into settings > cellular and only if it's active, after entering a name into "settings > cellular > cellular data network > personal hotspot > username field" u'll get an access to the personal hotspot option, which will be sitting in "settings > cellular > personal hotspot". this option will be there only if ur cellular (mobile) internet is on and will use only 3g-2g internet. when u connect to this hotspot from ur macbook, u'll be using ur mobile internet. u cannot use ur wifi (to read- free) internet using this combination iPhone + macbook pro, because as only u turn off "settings > cellular > cellular data" = off u wont be able to connect to ur iphone anymore.
please, correct me if i'm wrong.

- Creating a New Wi-Fi Service
- Copy and paste these instructions, because you'll be disconnected from the Internet and you'll need to reboot.
- Go into your Network Preferences > Select Wi-Fi Service (in the list in the left column) > Click on the options (cog icon) > Select "Make Service Inactive" > Select Apply.
- Select the same Wi-Fi Service > Delete It ( – ). Reboot.
- Return to Network Preferences > Create a New Service ( + ).
- Inside the prompt select Wi-Fi under Interface, name the Service Name something other than Wi-Fi. (I named mine Wi-Fi2. Apparently if you retain the previous Wi-Fi name the WiFi dropping will return on reboot.) > Click Create.
- Click Apply.
Restart the machine again.

Oct 31, 2014 7:30 AMby WaldenGreen,I can confirm this issue across several different MacBook Pro models and different access points (Linksys, Apple, Belkin) with differing encryption modes, so most likely we're looking at an Apple-software-specific bug here, not a hardware incompatibility. So maybe that will help a few of you in the troubleshooting process. I've had reasonably good luck just using the wifi indicator in the menu-bar to quickly turn wifi off and back on. So far that seems to keep things working for a decent amount of time before I have to repeat the process (often several hours on my primary MacBook).
(This isn't really all that new a thing; for some reason Apple manages to screw up wifi connections on both the Mac and iOS with nearly every major (and sometimes even the minor) OS updates. I don't know how they manage it since they are working with such a limited number of devices, but if you google it you'll find it happens over and over again. Best bet is not to upgrade until Apple has the fix in place so you don't have to spend hours trying to fix it.)
