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)

    Well Paul, I do believe this Fon issue may be fairly ontopic anyhow. The password question is very interesting. Passwords are usually stored in Utilities>Keychain Access, or in a browser specific keychain in the browser preferences.

    If the password is rejected, this may mean your Mac is erratically trying to switch to the Fon network, so the password gets rejected. Have you actually activated he fon/ auto fon network yet?

    Try to chuck the fon network out of the list of preferred networks in System Preferences>Network>Advanced>Airport. Drag your network(s) to the top of the list, and preferably create a different network name for the 2.4 and 5 GHz bands. Uncheck the box "remember networks..." Especially get rid of a possible "auto fon" network.

    Or do the inverse, and try and connect to the fon network exclusively. Create a different/ new WPA2 password for the fon network.

    Well, just a few suggestions for tinkering with... Good luck and happy hunting!

    I installed the Beta and after several days, the problem seems to have gone away. I use bluetooth keyboard, but hooked up old corded mouse, so only one BT device (don't have an old corded keyboard)

     

    Steve Jobs, please come back from the dead and get Apple back to quality control, "It just works" died with you.

    For any of you still experiencing those severe periodical Yosemite WiFi dropouts: It has come to my attention today that the daemon "secd", probably a "Discoveryd" component most possibly taking care of the iCloud keychain, is systematically causing CPU threads to crash, possibly thus causing unresolved DNS, and thence, Internet silence. No more data packets getting through.

    "secd" is fairly undocumented.

    Just for verifying/testing this theory: read this link and follow the advice quoted:

    http://apple.stackexchange.com/questions/159809/what-is-secd-process-on-osx-mave ricks-yosemite

    It looks like secd is responsible for syncing the keychain with iCloud?

    So what should you do? Try one or more of these:

    1. If you don't need iCloud keychain syncing, turn it off in iCloud preferences.
    2. Use launchctl to disable secd if it doesn't seem to adversely affect anything.
    3. If you need iCloud keychain syncing, see if you have a ton of keychain items, and remove the ones you don't need.
    4. Perhaps rebuild your keychain (make a new keychain, move items you need into it, and move it over the older one), in case there are unnecessary artifacts left over in the old keychain.

    If you are uncouth enough and have a backup, I might have an inkling as to a Terminal command that has remedied some issues in Mavericks and Yosemite as well (one of the first workarounds on this Yosemite issue), but with a variation specific to "secd", so far more targeted.

    $ sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.secd.plist

    $ sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.secd.plist

    You will have to provide your admin password, and mark well that under Terminal, the green cursor stays still while you provide that password- that is how it goes, rest assured. You may have to shut down and relaunch the secd preference list on every restart. A preference list is prone to rebuild itself (disabling it and reenabling it will probably clear its caches or the likes). Or just use the 1st command and see what happens.

    If I'm not tunneling down on the issue, please let me know.

    Well, good luck!

    Sorry Hex but I won't try this one - I am a bit of a whimp re Terminal and as I said to Mr Sympathetic earlier, I worry about applying fixes that might then stop me from suxccesfuly using the fixed Yosemite upgrade. Also I have invested recently in too many Safari generated passwords to now switch off KeyChain

     

    good luck I hope there's more adventurist people out there than me- I must off to my potting shed

    After months of Wi-Fi disconnecting multiple times per day, for two days now it's been faultless. All I did was to create a new profile on my broadband modem (it's a mobile wireless modem since we cannot obtain ADSL or fibre, "4G in, WiFi out"). This involved simply reentering into the modem our ISP username, password etc.

    This doesn't make any sense but something's changed and I haven't altered anything else. I'll post back here if WiFi problems begin to reoccur.

    Same problem.
    Box Fresh Macbook Pro with Yosemite.

     

    Tried every trick, starting to think that the software in the router needs a update.
    Or in other words, the computer or its software is not compatible with the network, yet.
    Every other gadget runs normal.

    Just try to kill the "secd" process by force quitting, or using the stop button in Activity Monitor. Or try my suggestions posted directly above (unload/reload "secd" using "launchtl" via command line).

    BTW: are you running the latest seed build 14C99d? Should do the trick as well, whereas 14c91f failed. Don't ask me about version numberings.

    Just running retail Yosemite 10.10.1 will be buggy as ****. It is already obsolete by far. 10.10.2 beta 5 is being evaluated for a retail version as I write.

    Big Beta count, usually v.3 does the trick. Early adopter, eh?

    Good luck!

    Right, LaMatti,

    Yosemite still may clash with OpenWRT, AsusWRT, Merlin, DDWRT, and the likes (firmware) routers. This needs to be investigated further still.

    After being sick of tired of not being able to use my Mac since the ill-fated Yosemite update, I went to the Apple Store today and had them re-install Mavericks, which took about five minutes. I had tried all of the suggested fixes on here and unfortunately none had worked. I'm glad to report that normal service has been resumed and my WiFi is now working as it should - quickly and with a stable connection. I wish I had done this months ago, instead of all the faffing about.

     

    I will be monitoring the situation with Yosemite closely, but no way will I be upgrading this until the WiFi problems have been 100% sorted. God knows when that will be.

    Well, God Speed, MattyB199! You did the right thing for the moment, and you not being into experimenting. Someday soon, I expect...

    My problem wasn't just with wifi. My rMBP has simply taken down my whole network. Wired/wireless... it killed indiscriminately. It took me a bit to realize it was my laptop doing the dirty work. I'd open the laptop, a few moments would pass, and everything in my house suddenly lost internet. It took me a bit longer to realize the solution, and I honestly can't believe I'm typing this: The answer was to just stop using Safari. I had blamed it on Yosemite, but whenver I was "hopping on" I was "hopping on" Safari!!!  So I switched, and suddenly everything became stable.

     

    Perhaps I'll reinstall Safari someday? Not sure what happened with that. Any guesses? (I DID empty my cache/cookies/etc.)

    I too have the same problem. It's infuriating.

    Well, after an almost flawless day yesterday - easy access to 5 ghz after a router restart (actually switch off/on) this morning a different picture (well actually almost the same picture)

    Sadly yesterday’s good performance not maintained overnight…

     

     

    1 connection when awaking had switched to 2.4ghz

     

    2 time machine's EHD "not ejected properly" error message - 1st for while; (can't remember if that started with Mavericks or Yos)

    3 could not reconnect to 5ghz - usual "invalid password" nonsense

    4 repeated brief red lights on hub this morning and auto reconnects

     

    So frustrating, disappointing
