Hi ..


Might be corrupted network preferences as a result of the upgrading.



Open the Finder. From the Finder menu bar click Go > Go to Folder


Type or copy paste the following:


/Library/Preferences/SystemConfiguration


Click Go then move all the files in the SystemConfiguration folder to the Trash.


Restart your Mac.



See if that makes a difference.


Your Mac will generate a new SystemConfiguration folder for you.


If that doesn’t help, try here > Wi-Fi: How to troubleshoot Wi-Fi connectivity

Carolyn,

you solved all my WiFi - Bluetooth related problem - THANKS!!!


As soon as I connected the Magic Mouse to my Macbook 15'' Retina, WiFi lost connection and tried to reconnect all the time, thus pulling down the entire network to zero performance. Update to 10.10.2 did not help a bit. But after deleting the configuration files as you suggested everything seems to run 100% smooth.

And imagine, I now can get back to work with the **** thing. Was kind of sick and tired using either the computer OR the mouse :-)


Thanks again and best regards

Thomas

I had same problem.. or so it looks.

Turned out to be some conflict between my bluetooth and wifi. With bluetooth turned on, continually problems with wifi and/or bluetooth. With bluetooth turned off: wifi worked perfectly...

I eventually found the solution here: http://osxdaily.com/2015/02/18/remove-bluetooth-pan-wi-fi-conflict-os-x-yosemite /

Turnes out that the bluetooth PAN in the network connections seems to be the troublemaker. I removed it just like suggested in the post at osxdaily, and my problem vanished... I hope it stays away. At least, now both my wifi and my bluetooth are working fine again..

Thanks for your post. It also seems that this problem affects iOS8. My daughter has been using an iPad mini retina since December without any problem. She recently bought a bluetooth keyboard to use with the iPad, now her wireless connection regularly drops, in fact every time she uses it. Confirmation of the connection between OS and iOS with bluetooth?

It really seems that Bluetooth has an issue/causes problem with the internet connection. On our MBP Retina 13” we were permanently connected to the router but the internet connection kept dropping.

Funny thing now: ⚠⚠ I disconnected/disabled the bluetooth but it had no impact on the issue. Connection kept dropping👿

I also reset PRAM and SMC without any effects.

Here it comes now:😮😮 in one the USB ports was the receiver for a wireless mouse. After I took this out the internet connection stopped dropping. As soon as I put it back the trouble started again.😕✅ As I am not an expert I can only presume that this is also a kind of bluetooth related problem

Updated to Yosemite 10.10.3 .... This is still an issue. Email and Safari can't function after a period of inactivity. Have to turn off wifi then turn it back on. Have followed threads and documents which haven't not eased the problem.Some say Bluetooth is the issue but since I have a track pad, turning off bluetooth isn't going to work for me.

I can confirm this is still an issue with Yosemite 10.10.3 on a MacBook Pro, 15'' Early 2011 model:


- no networking after few hours of inactivity, or after wakeup from sleep

- wifi shows connected state and full strength though

- wifi switch off and on does not help

- not related to bluetooth, i haven't switched that on for the past 4 years...

- when it starts, web pages load halfway and stop there (same in Safari, Chrome, ...)

- only complete reboot helps, logout-login does not


I am after a reboot now and Wireless Diagnostics found everything as expected, so I guess it's not an issue with my ISP or LAN.

Btw, every other device (2 iPhones, iPad, Apple TV) work perfectly.

I suddenly started periodically losing my internet connection over wifi. Same problem for the other members of the family on their MacBook Pro's. Nothing had been changed regarding our home network for a long time--at least 6 months, with perfect reliability.


Here's what worked for me:

Turn off every internet connected device in the house. Every iPhone, iPad, all the laptops (they're all MacBook Pro's various generations), don't forget the Apple TV or the old, retired iPhone that's plugged into the docking speakers in the garage as sort of a cheapo media center. Yep, we have a lot of Apple devices in this family.


Then turn off the cable modem and the router (in our case, a Time Capsule 2nd generation), let it sit off for a minute, then turn the cable modem and Time Capsule back on.


Then turn the various devices back on.


My internet connection to all the devices seems to be reliable again, at least for the last 12 hours. That includes all the family members who were also experiencing problems as of yesterday.


I have no idea if this discoveryd thingie was the origin of my problem, but this is where I got the idea for the above approach: http://bit.ly/1cj5Mrb

Having upgraded to 10.10.4 and after a problem solving mission with apple support I think I have found a solution to stop the wifi issues I was having when I upgraded to 10.10.3


My macbook lost wifi connectivity when i awoke it from sleep mode, so I would have to turn wifi off and back on again to solve the problem.


Apple support performed a lot of tests on my macbook and the one that seems to have worked is a SMC RESET.


Resetting the System Management Controller (SMC) on your Mac - Apple Support


Since i have done this reset, my wifi connectivity seems to be fine. I had previously tried system cache resets, checking my disk permissions for errors, checking my icloud integration, face time settings etc etc but nothing seemed to work.


I hope some of you may find this useful as I have tried every suggested fix in these forums and nothing helped.
