Oct 25, 2014 3:46 PM in response to iMarxellby Curveuk,I had the problem with failing wi-fi after waking from sleep on a MacBook Pro (mid 2012).
Tried many of the solutions described in this thread - the one which worked for me was disabling iCloud Drive, so it seems that that feature can also somehow mess up wi-fi....

Oct 25, 2014 6:17 PM in response to GalagBashaby smilingatlast,Wow! And I thought it was just me.
I upgraded my late 2013 MBP (retina display, full flash memory) from Mavericks to Yosemite about a week ago, and ever since I've had bad wifi problems.
Interestingly, the wifi problems occur only at certain locations, such as a nearby Starbucks in a Harris-Teeter store. It used to work perfectly there for hours on end. Totally glitchless. Now I get 15 or 30 "good" minutes of wifi access before it starts dropping the connection every 30 seconds. At that point, I have to pack up and go home.
Very frustrating. I will need to go back to Mavericks unless Apple figures out what's going on soon.
I'm sorry I upgraded!!! Fix it, Apple!

I am at a friends house with Yosemite DP6. He has a dual-band Cable company router/gateway. It has two SSIDs, once is 2.4G/20Mhz, the other is 5G/40Mhz.

Every time I connect to the 5/40 SSID (same as the 2.4/20 SSID), It drops every 30-60 seconds. the 2.4/20 works perfectly. Apple gear has had issues for a long time with 40Mhz channels. At home, I have all Apple TC dual-band units, which do not have this configuration, and I do not have any WiFi issues either.
Next time the SSID that gives you a problem, just alt+WiFi icon and note what band/width the SSIDs. Correlating these should help provide a better technical input for Apple to provide a fix.

Oct 25, 2014 7:19 PM in response to Curveukby bam.86,Tried this and it actually worked. I don't know for how long, though. Had to re-install Yosemite because I moved around some of the system files and the computer stopped registering thumb drives. Apple really missed with this new OS. I hope they soon will make an update to fix any and all bugs.

Just messing about and am using an Ethernet to Thunderbolt connection, and my god it flies, it's like having a different machine, no lagging when viewing pages, DNS works and I've got a decent speed.

Oct 26, 2014 10:09 AM in response to GalagBashaby Timmmmyyyyy,It's the backing up to the Time Capsule that kills it for me. I've tried a few of these but no luck. Tried to run a back up and it went.
For the moment, I'm backing up somewhere else.
Hope that helps.

Oct 26, 2014 10:30 AM in response to GalagBashaby stepbate,The best advice for those experiencing wifi instability issues after a Yosemity OX upgrade is to visit your local Apple Store. The staff there are can fix the problem in seconds, but because it's NOT an official Apple fix, it's apparently been kept under wraps.

Oct 27, 2014 9:06 AM in response to kunauby eddiefromglasgow,I was tearing my hair out with the wi-fi dropping every 30 secs, the only way I could fix it is to close my uTorrent, wi-fi has not dropped once since I closed it down, only drops when I start running it again, Tried changing to Bit Torrent and this is the same.

Oct 27, 2014 10:06 AM in response to eddiefromglasgowby peper-,Torrents heavily load network connections, cause they establish not one, but many connections at a time. So (and it is pretty often) router itself, but not Mac, can be a problem in your case. While I personally prefer to delegate torrents download to NAS (Synology in my case), which has gigabit wired connection to the router and works very nice with such tasks, could also recommend you at least to use wired connection for torrents even when downloading directly to Mac.

Oct 27, 2014 11:20 AM in response to GalagBashaby peper-,Majority of issues which are reported here, are somehow connected with bluetooth (or technologies, using it, like Handoff, AirDrop, BT mouse, etc.).
Two variants are possible:
1) Either Apple developers, while working on all this cool new features, messed smth in underlying bluetooth/wi-fi firmware and drivers. This is unpleasant, but not fatal. In such a case it could be repaired with software update in the (nearest) future. Just report this to http://bugreport.apple.com. The more users report it - the sooner it will be sorted out.
2) Or this is some hardware issue with Wi-Fi/Bluetooth in Macs, that shows itself under heavy load of Bluetooth (e.g. encryption). Not sure, if these two use the same hardware chip, but they can at least use the same antenna. This problem was not common before, cause not so many users of MacBooks use BT devices like Mighty Mouse (and mouse can be pretty lightweight device for bluetooth to work with). And now this became "visible" problem, cause Apple rolled-out these new features in Yosemite (Continuity, Handoff, AirDrop, Instant HotSpot, etc. all using BT) which a decent number of users are trying to check. Still, I hope this is only software issue and can be fixed.
