OSX Yosemite Wifi issues

Same, if not similar problem with Wifi and Yosemite:

Safari browsing is where I continue to have an issue. I'll browse for 30 seconds, maybe a minutes, then all of a sudden I'm waiting for Safari to respond. iPad is fine, iPhone is fine, just Mac cuts out randomly. I don't get it.

I'm pretty annoyed, I installed Yosemite, now my internet won't work. Wifi says connected, but App Store, Safari, and everything can't connect to Internet. If there's an update to fix it, how do I even get it without a connection? I tried plugging an Ethernet cable from iMac to modem, but that didn't seem to work either. The things other people said to try have been unsuccessful.

Hey everyone,

You guys have to turn off BLUETOOTH, which i know is super annoying.

I am having the same issues. it seems its either bluetooth or wifi, running them both is not happening.

it's got nothing to do with your connection network preferences or anything like that, or even the wifi band or router settings. it's entirely software driven.

we just gotta stay tuned for an apple update to fix the bug ridden OSX release.

First time poster here. I'm new to Apple, I own a Macbook Air 2014. Constant issues with Wifi since upgrading to Yosemite. Hangs on web pages and same issues whether I am on my router or my mobile hotspot through an Android phone. Tonight was so bad had to restart multiple times just to get a few pages to load before hanging again. I just turned off bluetooth and everything has been working perfect for 30 minutes. I know other solutions have been proposed but that is what has worked for me so far.

Sorry everyone, but I don't use Bluetooth at all, tried turning it on and off and the Wifi still drops out after a couple of minutes, on both 2.4GHz and 5GHz bands... thought I was doing something wrong but looks like others who have upgraded are sharing my frustration! I'm on a Late 2013 MBP Retina 15", can't understand how something so fundamental in the software can be this buggy? Any practical solutions anyone on what to do to get around this? Besides turning WiFi on and off...

I just got in touch with an AppleCare representative, you can potentially try resetting the System Management Controller, there is an article here on how to do this, and it's easy and safe Intel-based Macs: Resetting the System Management Controller (SMC) - not sure if this is the solution for everyone, but I have had some success so far, lets wait and see how long it will last!

And Handoff is working for the first time as well, so maybe this has solved the problem? Let me know if anyone else has the same result

I was able to maintain a stable connection with my 5 Ghz band but not my 2.4 band. Whenever the 2.4 band would start cutting out, I noticed my mouse would lose connection, as well. I did the bluetooth plist delete/restart and all has been well after that. I've been using internet on the 2.4 band for several hours now.

I have this issue, MBP Retina Late 2013. Slow wifi, drops out. Connected to a 7.7.3 AirPort Extreme and time capsule. Great signal strength. It just drops out randomly!

Any other symptoms? If you're having bluetooth mouse sluggishness or disconnects, try the bluetooth plist solution listed above. If not, try the other solutions in nicknish's post on page 2

I was reading on another post about this. They suggested the following in Terminal to keep BT and WIFI.

sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid

I gave it a shot and was able to connect with WIFI (disabled my ethernet which seems to be fine through all of this). Did not try it for more than 15 minutes that way but it seems to have helped for the moment. Tomorrow when I'm not on hard wired connection I'll try it for longer and report back.

For me, I lose my connection occasionally while Time Machine is doing a back over wifi. It doesn't happen every time, but it only drops during the backup.

Hey there, yeah I am having similar issue. I am running Yosemite on a MBP 15" early 2011.

At office I am running two routers

1) Linksys wrt54gc v2 dd-wrt - I can get connected to the WIFI but only to get cut off every 40 seconds or so (even when i disable wpa & wpa2);

2) Linksys wrt56gl Tomato 1.25 - it has stable connectivity but at a snail pace. Pings takes forever to complete (never), but oddly listening to online radio is fine.

At home I am running a Huawei router, WIFI or banwidth has no issues but instead Bluetooth connectivity to my wireless keyboard and trackpad range is only good with in 0.5 meters from my MBP before "lost connection" and "connected" starts dancing on my screen.

I do hope fixes for this comes out soon in OS X 10.10.1 😢

Hi everyone,

I have 13" MBP Retina - Late 2013. Upgraded to Yosemite yesterday and started getting having issues with wi-fi connectivity. Would drop the connection every couple of mins (even in the middle of an active download).

Tried all the solutions listed here. Nothing was a permanent fix.

Finally might have found a solution on Reddit.

My router is a mixed n/g/b router and was running all 3 bands.

I changed to 'g' only and it hasn't dropped the connection since. 20+ mins now. Longest connection since the upgrade yesterday.

Will try 'n' only in a little bit.

I have a D-Link 665 dual band router.

Hope this helps.

I am having the same issue when using my AirPort at home. I will have to see if the same issue persists when I am at work. One thing that I have just changed that appears to be working is to do the following steps:

(1) go into network preferences

(2) Select Wi-Fi on the left side

(3) Click on advanced

(4) Click on proxies

(5) Unselect all proxies (mine was set to auto proxy)

(5) Click ok

(6) Click on apply

I was loosing my connection every 30 seconds and would have to turn off Wi-Fi and then turn it back on in order to have internet connectivity. After turning off the proxy setting, I have been up now for an hour. I hope that this was the issue.
