Question: OSX Yosemite Wifi issues

Hi there,


I upgraded my Macbook Pro Retina 15" (mid 2014 revision) to OS X Yosemite last night and am now having issues when using my home WiFi connection. Whilst it connects to either the 5Ghz or 2.4Ghz network, it is basically unusable. Web pages take minutes to load (if they even load at all), dropbox doesn't sync because it can't get a connection and even trying to get to the router config page is extremely slow and hit/miss.


Tethering to my iPhone seems to work ok, as does using my home network via wired ethernet.


Are any others having problems with Yosemite? Wifi was working fine on Mavericks.


Tom

MacBook Pro with Retina display, OS X Yosemite (10.10)

I just tried something, which so far seems to be working. Go in to your Keychain access - System. Find your wireless network - double click. There are two tabs, Attributes & Access Control. Go into the Access Control and check "allow all applications to access this item". Mine was defaulted on confirm before allowing access, which I think was knocking me off every time I tried to do anything.


I'm not sure, but this is the first 10 minute period I haven't been knocked off since upgrading last night. Good luck!

I've been suffering from this same ailment since I upgraded on Thursday. After much gnashing of teeth (PRAM, SMC, reinstall of Yosemite, etc. etc.) I finally **RESOLVED** it by creating a new Network Location.


*under Network Preferences

*Click drop-down for Location

*Create a new location.. (I called mine "Internet")

*that's it!


hope it helps you too

Having problems with wifi after installing Yosemite?


Yes and it is driving me crazy. I've tried all the reported fixes and nothing sticks. Not changing the location, keychain access, Kext, etc. It may seem like it is changing for a few minutes but it always comes back. And it is across all wifi connections.

I will try that as well but I have narrowed this down a bit more.


My macbook has been working fine all day on the work Wifi which is a Linksys wireless N access point and like i said it also works fine when wifi tethered to my phone.


My home wifi is AC, the router is a talk talk 'super router'. It gives out AC on the 5Ghz band and N on the 2.4Ghz band. I have the same problem connecting to either. So out of frustration I changed back to my older talk talk router which just does N on 2.4 and so far so good. It works.


Maybe I have stumbled across a compatibility issue?

This is SOO annoying. Mavericks had its issues with JUMBO Frames that was never fixed but this is crazy now. Last night I upgraded to Yosemite from Mavericks. Now I can see my 5Ghz SSID but only have internet for 30 seconds at best. I don't even see my 2.4GHz network at all. If I toggle Wifi on and off I see the 2.4 for a moment and then gone. I removed all favorite wifi's and manually configured the 2.4 and will not connect. Removed that one and tried 5Ghz and same 30 seconds. I have done all updates, I have restarted numerous times and no go!


I did a fresh (clean) install. I formatted the HDD and had the original Lion install by default that came with the unit. It booted, had internet fine and then upgraded straight to Yosemite and immediately no wifi. Can anyone say if they did a clean install but from Mavericks and upgraded to Yosemite with same results??


What kills me is that apple doesn't seem to be giving ANY information out, no acknowledgement, and certainly no fix yet. I feel more and more like I am purchasing Microsoft Products where I am beta testing. If apple knew in Beta releases this was an issue with ALOT of people, they should not have released this yet! My laptop is my business and I am now tethered to a cable for everything!


Bluetooth disabled made no difference for me. Also I found that if I disable wifi while using my ethernet it will disconnect connectivity from ethernet until I unplug and replug...


APPLE ??? I guess I should just make some apple juice? or can I get some lemons??

I installed Yosemite on two computers: a 2013 Macbook Air and a late 2013 Macbook Pro. No problem with the latter one. Unresponsive Internet via wifi on the Air using my son's account. What is strange is that the Internet speeds are fine on the same Air using my own account with Administrator privileges. I tried some of the suggestions above as well as removing parental controls on my son's account, but no luck so far.

I for sure have this issue and it's very frustrating. Funny though, I could connect fine (it seemed) when using my non iPhone device at work for Internet sharing...seemed to keep the signal. But at home now, it kicks off after only a few seconds. I bet that the time it took me to type this, I got bumped off. Also, i notice, even when connected, the WiFi Looking for Networks notices still running...so it appears the PC is not understanding it is being connected. It appears. This is a major bummer!
