Q: OSX Yosemite Wifi issues

I guess Broadcom's lawyers can't find you...

Interestingly when I first tried connecting to Apple through its IP numbers rather than narrative address I was told No such website exists!!

I have gradually switched my devices over to openDNS and added .local to DNS searches - so far so good. Certainly internet is faster on the Mac presently

Yesterday I also deleted Bluetooth PAN...

Today my newest discovery is that no emails have gone for 3 days - all queued up nicely in Outbox - so off we go on another round of discovery...

"The world's most advanced operating system" brings you no internet and no email! ;-)

While I can accept things go wrong and nothing is perfect, I can't accept how long it's taking to sort this out.

I can't say much as I'm taking part in the seed testing and don't want to end up in court, but what I will say is non of the updates both official or seed have solved my BT problems. Bluetooth when switched on always, every time takes out my WIFI. It at the very least halves the speed some times takes it out completely.

This has been the case for me since October 2014 and that is unacceptable.

Agreed.  I returned my newly purchased 2014 Mac Mini.  I hate to admit it, but this was my solution (see below):   Purchased on eBay refurbished for USD $419.  Because of major issues with iTunes a few months ago (since more or less resolved, at the loss of years of ratings and play counts) - I've tried to take a "best of breed" approach to things and not get tied to to any one particular ecosystem.  So - other than a nightmare around migrating my Dropbox folder - it hasn't been that traumatic.  I use iTunes and iTunes Match for music (works on Windows too); Google Docs; Google Drive for cloud storage; and Dropbox to back up my Camera roll, which I then transfer to Google Drive at random intervals.  I miss Time Machine tremendously, and the trackpad on my Macbook.  But - pretty much everything else is OK.  Used my first Mac in 1988, but have also of course had to use Windows at work and even at home for a spell.  Installing Classic Shell turns Windows 8.1 into Windows 7 in terms of the Start Menu, so no big deal there.

I think Apple needs to "stand down" from gimmicky things like Continuity and Airdrop (both of which seem to also have lots of issues) and focus on getting the basics working rock solid.

Email Outbox now releasing mail - didn't change any settings except deleting a redundant account - who knows, maybe this IT stuff is all magic after all..

Can't see anybody blaming you for your action and lots will empathise and feel you did your best to be a positive victim.  Hopefully Apple will start to deliver machines that work and bring you back

I've read that the next version of iOS (9) is going to "focus" on "stability". I would have wished everything did/will.

5 months WiFi, BT, Mail, Time Machine are issues. Sad.

Very interesting (I lie - confusing) I just tried to login to my hub and safari couldn't find it via usual narrative address but using the numeral IP address it went straight there.  Remind me again what this means and why?

That means the OS will not have to do a DNS lookup to find that IP. DNS lookup is what they call "resolving DNS". And, Yosemite being connected to your WiFi router (as seen in the antenna symbol), but not actually connecting to internet or other devices on your network, is exactly what is a stake in the majority of the complaints here: DNS resolving issues.

That clear enough?

Clear enough but.... I have never had a problem connecting to the hub before using narrative address.  I am using both ethernet and wifi today - wifi connection rock solid (at least according to the antennae icon)  so assuming I am connected why wouldn't it connect on the narrative address? Thickie of London

Been running 10.10.2 since it came out and still the same problem.

Close the lid,bingo. That is, when I open the lid and try to connect to internet nothing.

Turn Wifi on off, reboot, etc, etc have tried all of the fixes from all of the threads and same problem keeps reappearing.

Very frustrating. I have 2 iPads and 2 iPhones (all software up to date) and they work perfectly on the same network that I am running my Macbook Pro, Retina, Late 2012 model. Not what I expect from Apple - have spent hours trying to solve this problem to no avail. There is just something deep down in the OS that is screwing everything up (by everything, the ability to connect to the internet when I open the lid to my beautiful brick).My internal network is working perfectly (hopefully Apple will not screw up my Time Capsule and AEX's). My problem is a pure "connecting to the internet" and it is a reoccurring one - it never goes away - unlike my internet connection which constantly goes away.

I have tried EVERY listed solution, they all work for less then a day (close the lid, couple of hours, open the lid - no internet). I'm getting tired of these work arounds that don't really work. BTW, I do get to the internet (obviously since I'm posting) after a wait of 15-30 minutes with the lid open. This is very bizarre since my iPhones and iPads work all the time. Another BTW, when I tried switching the ipv to Local my internet speed dropped by half, when I went back to automatic it returned to normal. No difference in the internet connectivity.

APPLE HELP!!!!

If switching your IPv6 to local only causes a drop in internet speed, it probably means IPv6 is already active in your vicinity. By all means leave it on "auto", then.

I am using both ethernet and wifi today - wifi connection rock solid (at least according to the antennae icon)  so assuming I am connected why wouldn't it connect on the narrative address?

If it doesn't connect on the narrative address, means DNS doesn't get resolved. The "full" antenna icon means there is good radio contact between the Mac and the WiFi router. 1st thing, you need stable radio contact. Next DNS Discovery needs to do its job. Which obviously it fails to do in some cases.

And what do you mean by running WiFi and Ethernet both?

Hi there! What we have here is a failure to communicate in Yosemite. Simply put Yosemite is unable to efficiently resolve DNS as Hex has posted many times. Most of the world's (and I use most loosely) ISP's are WINS Server based IPv4. They are not quite there yet to "pull the plug" on IPv4 just yet. An example of DNS resolve is found at my corporate workplace. Windows Server Domain. I.T. cringes and grits their teeth if a suit wants his Mac set up on the Domain. This even goes for Mavericks and earlier. Most of your consumer Routers highly suggest Windows Internet Explorer 9 and above or Chrome to use their Web Configuration page. Then, when you make the router changes, they are not "set" until you follow through with a hard boot not just a soft boot. DNS Resolution is where Yosemite is seriously failing. Apple is trying to get iPhone capability on their Laptops, iMacs, Mac Mini's and Mac Pro's. This is comparing Apples to Oranges. You don't attempt to "dummy" down your high-end computer OS just to suit your already simple iOS. Simply resolving and establishing your Home Network in your Hub and/or Router should be enough. As previously posted, simply changing your ".local" name in System Prefs>Sharing>Edit to a name unreflective of your computer's name, sets a NetBios Name that starts the DNS resolve. Then go into Prefs>Network highlight Wi-Fi click Advanced button change WORKGROUP to HOMEGROUP do this under ethernet as well (this is optional) works for me. That's it. Those should really be the only things an average user may change to establish network settings. Yosemite? It just ain't working out right for some. I now am using Ethernet and Wi-Fi together on my Mac Mini. Just had to address and resolve some network settings between Mavericks and Windows. Yep, NetBios, WINS and DNS is all it took. My router now sees the same computer connected in Mavericks and Windows. Like Hex said, leave IPv6 in Auto because you will find that most web sites are not IPv6.
