Slow WiFi issues after 10.10.2

If you are having slowness issues, and disabling bluetooth fixes it, it is probably a conflict issue with Bluetooth PAN and network drivers. Since I don't use the Bluetooth PAN (but do use BT for other things like keyboards, etc) I simply removed the PAN option from network setting and it resolved the issue.

System Preferences > Network. Highlight Bluetooth PAN, and click the "-" button at the bottom. You can always add it back if that didn't fix your issue, using the "+" icon.

I have been beta testing 10.10.3 for about a month, and all my wifi issues were SOLVED!!! Everything works as expected.

No they weren't.

Try downloading a big file and check your speeds with bluetooth on and then with bluetooth off. You will notice big diferences. That's not proper behaviour.

I think I’ve found a fix!

Go to: Wifi settings, then to the left select “Set Service Order", and make sure WIFI is the first one. Click set and wait for wifi to reconnect.

Worked for me 🙂

The solution from Henrik_K works for me for now. Thank you.

Can someone plz upload the newest driver file (ver7.1) for me? I need to access App Store but the original version that I kept does not work somehow. 😟

OMG!! You are awesome! I've been struggling with this ever since I updated to 10.10.2! Tried everything! Called my IPS like a hundred times, Apple customer service about another hundred with no success. All my other devices and computers would work just fine on my home network except my new MBA which stopped working after the upgrade. It would only connect if I put it literally on top of the router...so weird, used to work perfectly from any point of my apartment when I was on 10.10.1. I reseted my router a million times, changed network name and password, reseted my SMC and PRAM, tried everything I read in every blog until now that I finally saw yours. THANK YOU! Still, we shouldn't have to be dealing with this as customers and regular users. I am not a computer hacker!...had never in my life opened the "extensions" file for anything until now. Apple should have fixed this bug, not the bloggers.

Lysin, you made my day. Was going crazy about this but very quick fix thanks to you!

Q: I seem to have the same issue with my iphone and ipads. Any suggestions there?

Thank you, Lysin -- the driver rollback worked, and my WiFi speeds are back to a usable state once again!!!

Thanx if worked for me ! Quite incredible.

So, it was working for me for a while but eventually reverted back to its usual decelerating pattern. I finally resorted to what a few other posts have suggested, and bought an Apple AirPort router. I was using a Cisco E3000, and bought the Apple AirPort Extreme. On Day 2, and no issues so far... not even WiFi drops (which has been just as infuriating as the slow WiFi since upgrading to Yosemite).

If this is the only sure course of action, it would be ridiculous -- you'd almost have to wonder if it's by design. Still too early to conclude success, but so far so good... we'll see.

I was well still am having the same problem on my early 2014 Macbook-Air so it must be something with newer computers. I will try doing all that has been suggested about reverting to the 10.10.1 because my wi-fi is so bad I literally have to turn wi-fi off and back on again every time I want to go to a new link. I was looking up my problem on the internet and found this, and it sounds like it has been successful so I will defiantly try it.

I had the same issue with 10.10.3 but the IO80211Family.kext from 10.10.2 solved the problem for me https://dl.dropboxusercontent.com/u/5044929/IO80211Family.kext.zip ( install with Kext Utility http://cvad-mac.narod.ru/index/0-4 or any other kext tool )

Thank you @Rokotyan! The Kext Utility you posted, helped a lot!

I read all the post just about everywhere trying to figure out why my brand new 2015 MacBook Pro was only reaching 30 mbps download when every other device in my home was getting 90-105 mbps. The answer was so simple and tucked away in Apple's own pages. Open your router menu look for the WMM setting and ENABLE it.. reboot your router.. My Macbook Pro is now smoking the Web at 95 mbps ..
