Aug 21, 2015 4:24 AM in response to mattormondby pieter70nl,I wonder, did anyone tried an external USB WiFi dongle?
I have this problem also and I am willing to spend some little money, disable the onboard WiFi adapter and go with the dongle (they are small).

Sep 4, 2015 10:31 PM in response to mattormondby unbelievablejeff,I was having this problem for ages but only at home and have fixed it today. Please note for me the wireless dropout was only on certain networks, for instance it didn't happen when I connected to my work network.
Please note I tried the deleting the system prefs suggested above and it didn't work. I reinstalled the whole OS X Yosemite and it didn't work.
I am in the UK and have BT broadband, they supply the wireless router. As default the routers work at 2 frequencies, in this case 2.4GHz and 5GHz. As default your devices can jump across from both, however some Apple devices have an issue with this. To fix this, there is a setting on the router that you can split the frequencies so in essence you have 2 wireless networks with 2 SSIDs one at 2.4GHz and one at 5GHz. Once you do this and apply it the problem disappears.
Please see there full technical instructions here http://bt.custhelp.com/app/answers/detail/a_id/44798

Sep 15, 2015 6:22 PM in response to unbelievablejeffby FIRSACHI,I was frustrating to: I read every single comment, i did everything , i could..... Reset , reboot, PRAM, SMC, Automatically, channels change, nothing help I have Macbook. with Yosemite , my two other macbook air even i did upgrade them to Yosemite , still work fine, no random disconnect from WIFI. Also have in my household, windows based comp., three iPhones , all them work fine with existing Airoport extreme. My native language is russian, so idecide to go to russian sites and research there.... And that what i found! So far so good! Try this maybe it will help. Go to system preferences/ network/ advanced/hardware/configure/ (choose manualy)/ MTU (choose custom) type in 1453. and that should solve problem

Sep 16, 2015 3:27 AM in response to kultiginby Pasi Kolkkala,I think I found a solution to my Wifi instability. I had over 100ms pings to local router and over 30% packet loss during those pings. The issue started after upgrading to Yosemite and has come and gone ever since, even after the 10.10.5 update.
I was protecting my Yosemite box from the just disclosed AirDrop vuln and thought I'd disable my AirDrop peer-to-peer WiFi interface, and came across this post on Lifehacker http://lifehacker.com/fix-yosemite-wi-fi-issues-with-a-terminal-command-16634140 63
And disabling/enabling AirDrop interface with sudo ifconfig awdl0 down and sudo ifconfig awdl0 up actually makes an immediate difference in the ping times (I have ping -i 0.1 <local router ip> running while I do this).
Still on the fence about this, as the issue has always crept back after a few days, but this seems really promising

Sep 24, 2015 12:20 AM in response to mattormondby Daniel tzhenyao,I have faced the similar problem and I solved it after watching a youtube video (link below)
- Turn off wifi
- Simply unplug power source and do a complete shut down
- Then turn wifi back on
- SOLVED!

Oct 12, 2015 4:29 PM in response to mattormondby tomasz290,Hey, Had exactly same issue. Tried all advice from this thread and nothing helped.
What did it finally, was to go to network prefs / advanced ... and renew DHC lease.
Hope will work for you too. -
Oct 28, 2015 11:00 AM in response to mattormondby MisterMojo,I am also having WiFi disconnects since upgrading to Yosemite. Mavericks worked just dandy. . . All my network hardware is Apple with up-to-date firmware.
I tried logging-in via the Developer's Bug report page but it wouldn't accept my Apple ID. I assume that's because I'm not registered as a developer.

Oct 28, 2015 11:04 AM in response to mattormondby MisterMojo,Within three minutes of running Wireless Diagnostics in monitoring mode I experienced a dropped connection. I did this while I was trouble shooting the problem and before I read your suggestion.

Dec 6, 2015 8:49 AM in response to dannymdby ramsterine,I have tried everything listed on the internet. I ALSO tried power-cycle the modem and / or the router.
IT WORKED.
But there is one small problem...
The problem comes back again once I close the lid of my macbook pro. It appears that every time my computer has awaken from its sleep, my laptop finds it so hard to connect to my wifi. The connection drops every 4 seconds.
My temporary solution is:
1) Keep resetting my router every time my laptop goes to sleep.
2) Or, make sure my computer does not sleep at all.
