Q: 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)

    Thought I might throw this out there because it seems to be working for me now.
    After more than a month with a practically unusable macbook pro via wifi, i sat down last thu for a fix-it or ditch it day. tried everything i could find suggested on the web - here and elsewhere, at no avail.
    Finally, after looking at the console and seeing an instance of the below every 3 minutes or so:

     

    :wl0: Roamed or switched channel, reason #8, bssid 38:2c:4a:5c:84:xx

    AirPort: Link Down on en1. Reason 8 (Disassociated because station leaving).

    : SDStatusMonitor::kStatusWirelessPowerChanged

     

    ... I went into my Asus RT-AC87U W-AC2400 router and changed the 2.4G channel to static 9. I just picked a number, nothing special about 9...

    Haven't had a problem since EXCEPT this one:

     

    Connecting to Dropbox on 'com.getdropbox.dropbox.garcon.cafe_501'

    Could not connect to Dropbox on port com.getdropbox.dropbox.garcon.cafe_501. Trying again later.

     

    - no dropbox connection. I have a few other machines (PCs) and can connect to dropbox there through the same network, so i got rid of it.

     

    NO idea if these are related or not (can't imagine why dropbox would not connect after making it a static channel - nevertheless, my machine now works. no more sluggish web connections ether.

    I should note I also have google drive and this service seems to work fine.

     

    Machine is now behaving like before updating to Yosemite.

     

    hope this helps someone as a temp fix until Apple comes up with a fix.

     

    In case it does, let me know - maybe you know more than I do and can share why this is happening....

     

    Cheers!

    So is the consensus that 10.10.2 fixed the WiFi problems? I upgraded to Yosemite at its release but downgraded back to Mavericks because of the WiFi problems. Is it time to try Yosemite again? Or is it still unuasable?

    Is .2 only available to developers or everyone?

     

    I ask as I'm on Snow Leopard after installing an SSD and didn't bother upgrading to Mavericks let alone Yosemite until this issue is fixed.

    It's currently available to developers and select Apple Seed program members. I've been part of the original Apple Seed program for public betas, but haven't received it yet. I did get to beta test 10.10.1, so I'd say .2 is still a bit away from general release.

    I believe it is still in Beta as we speak

    Ah - OK - I hadn't realised that. Apple sent me an email suggesting that I try out 10.10.2. I hadn't realised they wanted me to beta test it again. I was in the original Yosemite beta test and fed back to them that wifi didn't work, which they then ignored. I think I will decline their invitation and wait until Yosemite actually works this time.

    Ya, 10.10.2 was released 3 days ago…..that's why I asked if it was just beta as I haven't read any big news that it fixes the issue. Just little blurbs here and there.

    I spent two hours on the phone with my ISP today trying to fix my prehistoric wifi internet speeds (0.17 Mbps and worse) thinking it was their fault. I didn't even consider the possibility that the issue could be my Mac which is less than six months old. I mean why would it be? This is 2014 and that sort of thing only happens on PC's right? It was only after numerous tests we were able to narrow the problem to my computer rather than anything else. I then went online and saw the well publicized issues with Yosemite and suddenly it all made sense. I upgraded when it came out and have had stupidly slow internet speeds ever since. It is literally unbelievable that Apple would release a software update that means many people can't use the internet on their macs. What a complete joke.

     

    I've seen the various temporary fixes available, most of which appear to be band aids. Frankly I don't see why I should waste time having to fix and issue like this but even then I wouldn't mind so much if the solutions was simple and permanent. I see the next update is imminent and like everyone else am hoping this provides a fundamental solution. I am a long time Apple loyalist but this is totally unacceptable.

    Just upgraded my MBP Retina mid 2012 from Mountain Lion to Yosemite 10.10.1 today. Didn't know about the wifi problems before I did it. Wish I hadn't upgraded now. Now it loses wifi connection after waking from sleep every time. Sometimes OSX reconnects on its own (I think), most times I have had to select the network again. Also had to turn wifi off and back on a couple times.

     

    This really is unacceptable. What a joke. W T F, Apple?!

    Not that I know of.
    And I am not waiting... a static channel has worked for about a week now - it's an easy fix and also easily turned off once Apple actually fixes the problem.

    There are many many suggestions on how to fix it. ATM the only thing you can do is try them and with some luck, one will work for you.

    I was experimenting with a Cisco 2700 AP this weekend and hit this issue.  Using iperf3 I noticed that my 2011 Macbook Air was getting around 150 Mbps transfer rates (the stated wifi connection speed was 300Mbps), yet my early 2013 Macbook Pro retina sitting next to it was getting 40 Mbps max, despite its stated wifi connection speed of 450 Mbps.  Performing a file copy of a .iso image from my local NAS confirmed the discrepancy.  Both are at OS X 10.10.1.  The difference I note is that the Broadcom firmware version on the Macbook Air was 5.something, whereas the Macbook Pro was 7.something.  My wife’s 2012 Macbook Pro at Mavericks 10.9.5 was getting 300 Mbps actual transfer rate with iperf3.

     

    I have other partitions on the Macbook Pro so I installed Mountain Lion and found I was getting around 300 Mbps actual transfer rate as well.  Boot back to Yosemite on the same system and I get 30-40 Mbps.  I googled some and found that others had downgraded the wifi firmware by replacing /System/Library/Extensions/IO80211Family.kext so I tarred up that from the Mavericks system.  After replacing that and performing an SMC and PRAM reset I saw that my Macbook Pro was now at wifi firmware 5.106.98.100.24 and I was getting better than 300 Mbps.

     

    Note that connecting to a current generation Airport Extreme with both the old firmware and the new I get 280 Mbps, so whatever changed in the Broadcom firmware explicitly did not affect Apple Airport products but seems to cripple at least some non-Apple wifi access points.  I also see that an iPhone 6 is crippled running against the Cisco AP vs the Airport Extreme as well, but on the other hand a new iPad Mini gets twice the throughput with the Cisco AP vs the Airport Extreme (I believe both of these devices support 802.11ac, which is configured on both APs).  Weirdness!

     

    I’m looking forware to seeing whether 10.10.2 actually fixes the issue!
